The operating principle of cruise control and instructions for use. How does cruise control work with a manual transmission? What does active cruise control mean?
During long trips, many drivers are faced with the fact that constantly keeping their foot on the gas pedal in a fixed position leads to rapid fatigue. It is to simplify driving when driving long distances that a system called cruise control is installed in modern cars.
Take cruise control on a long road trip
That's why it's so important to learn how to use cruise control on long trips. Currently, installation of such a system is possible both on cars with manual gearboxes and automatic ones.
What is cruise control
Cruise control is a system designed to automatically maintain a speed set by the driver. Activation of this system in a car allows you to maintain a given speed limit regardless of the terrain, without resorting to tiresome mechanical action of your foot on the accelerator pedal.
In cases where the road situation requires an increase in speed, for example, to overtake a passing vehicle, the driver simply presses the gas pedal and the car accelerates. To slow down the car, the driver.
Pressing the brake and gas pedals will temporarily disable cruise control.
However, when such manipulations are stopped, the system is automatically activated and restores the previously set speed, information about which is stored in the internal memory of the device.
Automatic speed control (cruise control)
The adjustment system has a cruise control switch - usually in the form of a single button. However, there are options with several buttons for different functions. Standard cruise control has a button that allows you to activate and deactivate the system. Another button, designated “set,” is used by the driver when the car reaches the desired speed. To improve information content, a corresponding indication is displayed, reflecting all actions with cruise control. Increased traffic on motorways has meant that standard cruise control, called passive cruise control, is increasingly being replaced by adaptive cruise control, which is a more advanced version of the system.
The main advantage of adaptive cruise control is the presence of additional functions that, although they do not replace the driver, make driving much easier and more comfortable. Such functions include automatically maintaining the distance to the vehicle in front, preventing unauthorized rolling down slopes, automatically braking when an obstacle occurs, etc.
Cruise control control
Cruise control can be activated both while driving and when the vehicle is parked. The activation of the system is accompanied by a corresponding light indication on the dashboard, the color of which depends on the car model.
Pressing the cruise control lever causes the vehicle to reach and maintain the last stored speed.
Typically, it can record speeds of 40 km/h and above. The presence of an emergency function in the cruise control allows you to instantly turn it off when you press the brake pedal.
Cruise control switch button
To control the cruise control function in some car models, only one button is used, pressing which automatically turns on the system. In this case, the cruise control is turned off by pressing the brake pedal by the driver. If there are five standard buttons on the car panel or a special cruise control control lever, the system is turned on slightly differently. Pressing the “on” button brings the on-board computer into a ready state, and cruise control is activated by pressing the “set” button, after which the speed is adjusted by pressing the gas pedal.
In order to determine the procedure for turning on the cruise control system installed on a particular vehicle, you need to carefully examine the control lever. The simplest cruise control systems, controlled by just one button, are automatically activated when the button is turned on and turned off when the brake pedal is pressed. The speed is adjusted by pressing the accelerator pedal. In other cases, when the cruise control is controlled using five standard buttons, turning on the cruise control (the “on” button) only means that the car’s on-board computer is ready to activate this system, which is done by pressing the “set” button at the speed set using the gas pedal.
Some features for different types of cars
Two of the additional buttons are designed to increase and decrease the vehicle's speed. In most cases, each press increases or decreases the speed by 1 km/h.
cruise control may have several buttons
Here's a little instruction: cruise control is controlled by additional buttons
- Acceleration. Lightly pressing the lever and holding it in this position allows you to gain the desired speed without the driver pressing the gas pedal.
The accumulated speed is recorded and recorded in the device’s memory by releasing the lever.
Interruption (failure) of the set speed occurs in cases where the current speed for 1 minute exceeds the one recorded in the memory by 10-16 km/h (depending on the car brand), or the current speed is lower than the set speed by 8-10 km/h . To adjust the speed, you must recall it again from the cruise control memory or set it and save it again.
- Slowdown. Slowing down using cruise control is done in the same way: the corresponding button (lever) is pressed and, after reducing the speed to the required speed, it is released. In this case, the speed is fixed, and its value is stored in the device’s memory. Short-term presses lead to a decrease in speed by 1 km/h. In some cars, for example, the BMW 525td, as well as cars equipped with an automatic stability control system, in order to maintain speed, you need to write the set speed into the device’s memory and then use the cruise control in this way, the memory, relatively speaking, of this device already helps.
- Shutdown. The system is turned off by lightly pressing the corresponding button. Current driving conditions do not matter.
Turning off the engine leads to erasing the speed recorded in the device’s memory.
In addition, cruise control is disabled when the driver brakes, when acceleration exceeds 1.5 m/s and when the automatic transmission control lever is moved to the neutral position (position N).
How to use cruise control
Special switches installed on the clutch and brake pedals allow you to adjust whether cruise control is turned off. The system also provides for the installation of a pneumatic actuator that regulates the throttle valve, which allows the vehicle with activated cruise control to move without the driver pressing the gas pedal. In this case, the fuel supply is adjusted using a special cable connected to the throttle valve.
Thus, the cruise control control unit is a real minicomputer that quickly analyzes a lot of data entering it and maintains a given speed limit, being a successful example of the real implementation of the theory regarding automatic control systems.
Think about safety
Ride comfort is not only about caring for the driver's feelings.
A tired driver can make a mistake that will lead to very sad consequences.
This is especially important. Several hours of driving, and even several days in a row will challenge anyone, even a physically strong person.
Cruise control is important for driving safety
Video - how to use cruise control
Conclusion!
Modern means of increasing comfort are offered by car manufacturers, including to eliminate such unpleasant complications. Even a novice driver without much experience would do well to learn how to use cruise control while driving. This is not particularly difficult and does not require much labor. But it will only bring benefits.

Without cruise control, traveling long distances would become tiresome and contribute to driver fatigue. Let's tell you: what it is and what it is needed for, how to use it, what is the difference between passive and adaptive.
What is it and how to use it?
Cruise control is a device that maintains a constant vehicle speed by automatically increasing or decreasing the gas on its own. without driver participation. Most often, it is used while driving on highways. The driver sets the optimal speed at which he intends to drive, and the system itself presses or releases the gas pedal.For example, we set the system to 100 km/h (additionally adjusts within plus or minus 5 km/h) in order to keep the highway limit to 90 km/h plus the permitted 20 km/h and not get fined. The driver can only steer. The system may reduce speed on downhill slopes or when approaching a slow vehicle. After passing it, it will automatically dial the specified value.
In urban conditions, where the speed of the car is not constant, it is not needed. For safety reasons, cruise is switched off as soon as you press the brake pedal and is inactive when driving below 40 km/h.
For ease of use, the cruise buttons are located directly on the steering wheel and consist of 5 main ones: On (turn on), Off (turn off), Set\Accel (set/increase), Resume (restore), Coast (lower). Plus a brake pedal that automatically turns off the system.
Everything is clear with the on/off buttons. When you press the Set/Accel button, the cruise control will record the speed at which you are currently traveling. If you press this button again, it will increase by 2 km/h. If you brake, then to restore the lost speed you need to press the Resume button. If you hold the Coast button, the speed will decrease.
What is adaptive cruise?
There is an adaptive type system that monitors the speed of the car in front or the topography of the road, and knows where there will be turns, descents, and difficult sections. Depending on these conditions, it automatically adjusts your speed and maintains a safe distance between two cars. Those. in essence, this is the ability of a car to move autonomously with minimal driver input. In some cars, it is able to go around slow cars or change lanes.This opportunity will appear thanks to the installation of a radar and a digital processor. This type is called active. Traditional cruise control is considered passive and does not automatically adjust the speed; you must do this yourself.
Let's look at an example of how active cruise control works on Mercedes cars. It works when they are positioned behind a car and uses a video camera to point at the license plate of the leading car. Then your car will follow the leader as if tied, if he does not change lanes, and the road is not a mountain serpentine with sharp turns.
If the car in front slows down, the system sends a signal to reduce speed. When the road is empty, it gives a signal to restore speed. If you have a passive cruise, then you must slow down and then also independently restore the speed to the set one.
Active cruise control operates at speeds from 30 to 200 km/h. And the main condition for its use is Under no circumstances should you take your hands off the steering wheel, otherwise it will turn off. There are also options when the car follows the road markings and moves within the lane, rather than looking for another car. In essence, adaptive cruise is an automatic driving system without a first-level driver, but which still requires driver participation in the process.
Video review using an example
Active cruise control is designed to help avoid collisions with vehicles ahead. If the system does not have time to reduce speed and there is a possibility of a collision, it signals the driver to apply the brakes or move away from the collision. In advanced systems, it is capable of braking independently without driver intervention.
Not all modern drivers know what cruise control is in a car. However, this option belongs to rather old systems installed on foreign-made vehicles. This system is designed to provide comfort and convenience when driving on country roads. There are many benefits to using this option, so let's look at the characteristics of cruise control.
Cruise control: what is it?
Cruise control is an additional vehicle option, thanks to which the speed is maintained at a certain level. This function is used exclusively for long trips on country roads or highways. When driving in urban areas, this function is not used.
This is interesting! On domestically produced cars, the cruise control system began to be used relatively recently, and only on luxury trim levels. If the need arises, you can install it yourself, which is what many owners of Russian cars do.
The cruise control system functions as follows: the driver drives out of town onto the highway, after which he turns on the option to support a certain speed limit. Regardless of the road surface, the system will maintain the speed at a certain level. This allows the driver to take his foot off the gas pedal and not control the speed.
Appearance of the cruise control buttons located on the steering column switch
The system in question is not a new product at all, but it gained popularity in Russia not so long ago. In Western European countries, the use of cruise control is the norm, as the system eliminates driver fatigue during long journeys. This option is installed from the factory on cars with different types of engines and transmissions. If the system in question is not installed on the car from the factory, then this is not yet a reason to change the vehicle. You can install it yourself, and even a beginner can cope with this task.
The invention of the cruise control system occurs in the USA, where the device is extremely popular. Today, manufacturers from different countries are producing such a system: Germany, Japan, China and others. Translated from English, “Cruise Control” means “constant speed control.” However, in addition to controlling speed and reducing driver fatigue, this system has another significant advantage - fuel economy. Numerous studies among motorists have revealed that fuel savings correspond to values of up to 5-7%. This is another reason to equip your vehicle with cruise control.
Features of operation on manual transmission and automatic transmission
On vehicles with manual transmission and automatic transmission, the operating principle of cruise control is the same, with the exception of some points. These points lie in the number of functions performed by the devices. However, let’s look at the initial components of the device and its operating principle.
The design of the simplest cruise control consists of a servo drive, which is connected to the throttle control mechanism. It is the servo drive that is responsible for supplying a certain amount of the fuel mixture. A servo drive is a negative feedback product used when driving a vehicle with a manual transmission.
Cruise control servo drive responsible for fuel supply
The operating principle of the device is as follows:
The cruise control module analyzes the information received and also compares it with those specified by the driver. Based on information processing, a specific car control algorithm is created. Now let’s figure out what are the differences in the functioning of the cruise control system for cars with manual transmission and automatic transmission.
How does the mechanical system work?
When using the cruise control system on a car with a manual transmission, the sector stops at the limiter. To do this, the driver should change from high to low gear. In addition, with a manual transmission, the driver needs to independently press the brake pedal if the need arises.
On a car with a manual transmission, when driving uphill and with the cruise control option activated, the driver will need to switch to a lower speed. If you don’t switch to it when going up a steep climb, you simply won’t be able to overcome the obstacle. The same applies to the situation when a car goes down a hill. If you do not shift to a lower gear for engine braking, the engine will develop a high speed.
Video: cruise control on a Suzuki Grand Vitara with manual transmission
How does the automatic system work?
On “automatic”, with the cruise control option turned on, there is no need to switch, since the device is responsible for all actions. As soon as the car reaches the desired speed, the servo will fix the position of the damper. If an adaptive type system is installed on a vehicle with an automatic transmission, then the car braking occurs automatically.
Types of device
There are two types of devices under consideration, which are called passive and adaptive. The first option is a classic system that is used on cars with different types of gearboxes for a long period of time. The main function of passive devices lies in maintaining a certain speed of movement.
The adaptive type is the most interesting and in demand, so we will deal with each type separately.
Passive cruise control and its features
The passive type of cruise control has the simplest design, and such a product is used primarily to maintain a certain speed while driving on highways and highways. The design of the passive device includes the following structural elements:
The device operates quite simply. To do this, you need to go out of town to a highway with good road surface. It is not rational to use this option, both in city traffic and outside the city on roads with poor-quality road surfaces (if there are potholes and other defects on the roads, as well as on primers). As soon as the car reaches a certain speed, which is optimal for a given area, the cruise control is turned on (manually).
After enabling this option, the microprocessor located in the control unit is responsible for the speed of movement. Sensors determine the speed of the vehicle, as well as the throttle position, and transmit information to the control module. When driving conditions change, which can be ascents and descents, the sensors send appropriate signals.
It is important! The sensors do not detect other types of obstacles, so the driver should be careful when the cruise control is on.
As soon as the type of track changes when driving uphill or downhill, the sensors send signals to the control unit. The unit analyzes the signals, after which it sends a command to the servo drive, and the throttle valve closes or opens.
Adaptive cruise control and its features
The adaptive type of cruise control is a new generation of the device. This type of device is used on modern cars, and is intended not only to maintain a certain speed limit, but also to take into account the traffic situation. The traffic situation is taken into account using auxiliary devices: sensors, radars and cameras.
The use of adaptive cruise control makes it possible to link your vehicle to the car moving ahead. The speed of the vehicle ahead is taken into account, and a safe distance is maintained, on the basis of which the control unit controls the vehicle.
Location and overview of adaptive cruise control sensors
If the car moving ahead changes speed, the sensors will send corresponding signals to the ECU. The unit will analyze the signals and make a decision to reduce or increase the speed. If there is no vehicle ahead, the device gives a signal to increase the speed to the required value, after which it maintains it.
This is interesting! There are also cruise control systems that can read road markings. This feature allows the driver to eliminate the need to drive a car.
Adaptive cruise control is designated ACC. This type of system is installed on cars from the factory. The cost of such a system is quite high, due to the use of expensive sensors, cameras and radar. The device also uses a modern control unit, capable of calculating not 2 functions, but several dozen. Depending on the device model, the driver can be notified of an emergency situation ahead by both visual and audio signals.
It is also important to note the fact that the adaptive cruise control system operates in tandem with the ABS anti-lock braking system and ESP. If one of these systems does not function, it will be impossible to activate cruise control. It is recommended to turn on adaptive cruise control when cars are moving at a uniform speed outside the city.
Displaying the adaptive cruise control system on the vehicle's on-board computer
If the vehicle design does not have an adaptive type of cruise control, then its installation does not make justifiable sense. Although this system is more advanced and modern, a passive device is quite sufficient for trips outside the city.
How to use cruise control
What cruise control is in a car and why it is needed was discussed in detail. It is important to understand the question of how to use this device correctly. After all, many motorists, when switching to foreign cars, do not understand what this option is and how to use it correctly.
If a car has cruise control installed from the factory, the control buttons for this option are often located on the steering wheel, and only occasionally on the steering column switches. If you install the cruise control yourself, then a special control panel with several buttons is installed on the steering wheel.
Cruise control buttons located on the Hyundai multifunction steering wheel
The location of the control panel on the steering wheel is the most convenient, since at any second you can not only enable the option, but also disable it or make settings. However, some car models are equipped with control panels located on the steering column switches.
Control buttons for standard cruise control on Lada Granta
Depending on the vehicle model, as well as on the design of the device, there are some differences in control. The cruise control control algorithm consists of performing the following manipulations:
- First, you need to accelerate the vehicle to the speed at which you plan to continue moving. The minimum speed at which the device can be turned on is 40 km/h.
- Enable option. This is done by pressing a button in the form of a tachometer with an arrow or moving the regulator to the “ON” position.
The cruise control system is activated by pressing the button with the corresponding icon
- In this case, the corresponding white or yellow indicator will light up on the instrument panel, which usually looks like a tachometer with an arrow. If the device was installed on the car yourself, then no indicators on the instrument panel will light up. The indicator glowing white or yellow indicates that the device is turned on, but this function is not yet working.
The yellow icon on the instrument panel indicates that the cruise control device is turned on, however, for it to fully function, you must press “SET-“
- The system is put into operation by pressing the “SET” button with a minus sign. On some car models, the name of this button may differ, however, the activation principle is similar.
Motorists who often travel along the highway do not skimp on installing the function, even if it does not come as standard on the car.
- In this case, the indicator will change from white or yellow to green, which indicates the functioning of the device.
The green icon indicates the operation of the cruise control function.
- If you need to increase or decrease the speed of movement, you can use the plus and minus buttons. When you press these buttons, the speed of the car will increase or decrease by a value from 1 to 2 km.
To turn off the device, press the “Off” button. This is a complete disabling of the option, and is performed when you enter the city. An emergency way to turn off is by pressing the brake pedal. In this case, the system goes into readiness mode (lit with a white or yellow indicator). You can turn on the option at any time and continue moving along the highway. It is often used when you need to overcome an obstacle, make a stop, etc. Another way to turn off the device is to press the gas pedal. This shutdown option is used on vehicles with adaptive systems installed.
More details on how to operate cruise control on your car can be found in the manual for your vehicle.
Let's look at some designations of cruise control options:
- On – switch on.
- Off—disable.
- Set Accel – setting the mode.
- Resume – remembering speed.
- Coast – speed reduction.
Video: how to use cruise control
It is important to mention that the cruise control has a self-off function. The following factors serve for this:
- If a sudden acceleration occurs at 5.4 km/h.
- If you move the lever to the neutral position on a car with automatic transmission.
On vehicles with a manual transmission, the cruise control will not turn off when the gear shift lever is moved. The car will slow down, but the sound of the engine roar will be heard.
To summarize the device under consideration, the following advantages should be noted:
- Opportunity for the driver to rest. In this case, the driver can only relax his legs, but not his arms or head.
- The ability to install the device on any car, even if it is not equipped with the option from the factory.
- Reduced fuel consumption by 5-7%.
- Using the adaptive view of the device allows you to automatically maintain not only speed, but also distance.
Cruise control, like almost any function, has its downsides:
- If any sensor of the device malfunctions, the system will not function. This is especially true for the adaptive control system.
Laziness is the engine of progress, and the example of cruise control, which came to the automotive industry from the USA, confirms this. Lazy Americans, whose distances from one city to another are measured in thousands of kilometers, complained that their legs were tired of constantly keeping their foot on the accelerator pedal. And their complaints were heard - engineers developed a special system that, without driver participation, could keep the car moving at a constant speed. This is how cruise control appeared, which will be discussed in this material.
From simple to complex
The first automatic speed control systems appeared in the mid-1950s. They were tested for several years on Chrysler vehicles. It was this company that decided to be the first to make the dreams of American motorists about autopilot come true. And although cruise control did not perform all the functions of the autopilot, maintaining a constant speed without human intervention was already progress. The debut of this system took place in 1958 - the Chrysler Imperial production car equipped with cruise control went on sale and showed significant commercial results in the same year.
The operating principle of the first cruise control was simple: special sensors read information from the crankshaft and, focusing on its rotation frequency, controlled the supply of the required amount of fuel to the engine through a special solenoid. At the same time, the driver did not need to press the gas pedal - the system did everything itself. Over time, the cruise control algorithm became more complex. New systems were able to control the fuel supply, focusing not on the crankshaft speed, but on the speed of rotation of the wheels or engine speed. In addition, the improved cruise control mechanism allowed the driver to set the speed with an accuracy of 1 km/h. This value was taken as a step, and the car owner could adjust the speed of the cruise control by adding 1 km/h to the already set value.
The cruise control system is activated by a button located on the dashboard or on the steering wheel.
The driver can select the speed that the system will maintain, and when it is necessary to exit “autopilot”, just press the brake pedal. In modern cars, cruise control is installed on both models with automatic and manual transmission.
The evolutionary development of the system was the invention of adaptive cruise control. The new mechanism was named so because the system, in addition to maintaining the speed of movement, can independently, depending on the road situation, adjust the distance between cars traveling in the same direction ahead. Thus, if simple cruise control is an option for the lazy, then adaptive cruise control has become part of the car’s active safety system. Adaptive cruise control consists of a radar, an electronic control unit (it includes longitudinal controllers and a digital signal processor), sensors that read information from systems.
The principle of operation of adaptive cruise control is as follows: a radar installed in the front of the car (usually located behind the radiator grille) constantly monitors the area in front of the car. When it detects a car ahead, it sends a signal to the electronic “brain” of the system, where the received information is processed. From there, the data goes to the brakes, ABS, EBD, ESP systems (if there is a short distance to the car ahead and you need to maintain a safe distance), and the engine. When the distance to the car in front increases, adaptive cruise control sends a signal to the above components and assemblies to increase the speed.
Advantages and disadvantages of cruise control
Cruise control is a fairly convenient system that has a number of advantages. Firstly, it relieves the driver of the need to constantly adjust the speed of the vehicle. Secondly, it allows you to save fuel - when driving at a constantly set speed, fuel is not consumed as intensively as when driving at a variable speed. Third, adaptive cruise control is an effective safety system.
The disadvantages of cruise control are purely technological. If the sensors become clogged, the radar malfunctions, or there is an error, the adaptive cruise control system may decide that a vehicle is moving at an unsafe distance ahead and sharply reduce speed until it stops. And the driver may not be ready for this. Well, one more minus - cruise control relaxes and makes the driver less susceptible to changing road conditions.
An article about what cruise control is, why it is needed and how to use it. At the end of the article there is a video about cruise control.
The content of the article:
Automotive technology is constantly evolving, offering us an ever newer and more modern approach to a car and the convenience of driving it. One of these systems is the so-called cruise control - it is better known in Western countries. Not many people are familiar with her work, so let's take a closer look at her.
The main task of the cruise control system is to maintain the set speed limit in the car. The homeland of its developers is the USA, where the system has demonstrated its usefulness during long-distance travel.
It doesn’t make much sense to use the system in the city, and we’ll see this later.
The system is turned on by the driver after leaving the city, which leads to the establishment of an optimal speed of movement, which is automatically adjusted when road conditions change (the presence of descents or ascents). There is no need to hold the accelerator pedal when the system is on, so the driver has the right to slightly relax the lower limbs, which is reflected in the reduction of fatigue after the trip.
There is no difference in the transmission when installing cruise, since it supports operation on both manual and automatic transmissions. There are passive and adaptive control systems.
Passive control system
The first type of system is considered classic and consists of only a few components:
- Control block;
- control sensors;
- throttle position control drive.
If it is necessary to increase or decrease the fuel supply, the sensors transmit data to the unit, which facilitates the opening or closing of the throttle. And the required speed is maintained without the active participation of the driver himself.
Adaptable control system
If the “passive” system is designed only for driving at a given speed, then the adaptable system is capable of calculating the situation on the road.
Adaptable cruise control involves the installation of auxiliary sensors, as well as cameras and radars that transmit information to the unit. This type of cruise control allows you to move together with the car moving in front, helping to adapt to its speed. The required distance is maintained.
As soon as the front car changes its speed, the sensors will be able to detect this change and transmit the received information to the unit, which will adjust the throttle position.
The most modern adaptive cruise control systems are also able to perceive road markings - this helps to move in only one lane, without driving into oncoming traffic or the side of the road.
Since the control buttons are located in the steering wheel, operating the cruise control is not difficult. The buttons are as follows:
- ON/OFF– button to activate and, therefore, deactivate the system. On some models it may not be there at all;
- SET/ACCEL– button to record the current speed. If you press the button once, the cruise control will remember the current speed and will calculate the throttle position exactly for it. If you press it a second time, the recorded speed will increase by 2 km/h. By the way, when setting the speed on the control panel you will see the inscription "CRUISE ENGAGED", which indicates that the cruise is on;
- COAST– speed reduction button. Pressing it once will reduce the speed by several km/h. Holding the button will reduce the set speed further;
- RESUME– button to return to the speed that was set some time ago.
But it should be remembered that the system is not capable of storing specified information for a long time when disabled, so RESUME will only be relevant during a short deactivation.
If there is no button on the steering wheel ON/OFF, cruise control is activated by pressing SET/ACCEL, and deactivated by pressing the brake or clutch.
In the event of a potential malfunction in the cruise control, you must ensure that there is no damage. If after pressing the system activation the message does not light up CRUISE ENGAGED– the light bulb responsible for this has burned out. It will need to be replaced.
To indicate errors in the cruise control, press the RESUME button for a few seconds. The CRUISE ENGAGED indicator will light up and then go off. If there are any malfunctions, the indicator will display error codes:
- code 01– problems with the wiring of the control unit. It is recommended to check the functionality of the ON/OFF button, as well as the system’s response to pressing the brake;
- code 05– there may be a problem with the fuse. It is recommended to check it and the wires connecting it to the cruise control;
- code 07– problem with cruise activation/deactivation. It is recommended to check the ON/OFF button, as well as the operation of the sensor responsible for receiving the signal from the brake pedal;
- codes 011, 012– problems in switching the system. It is recommended to check the cruise control switch.
Conclusion
Cruise control is especially useful if you often drive outside the city. It helps you feel less tired while driving, allowing you to concentrate on the situation on the road. The only thing is that it is not recommended to use cruise on wet or slippery roads, as well as in fog, so as not to create emergency situations. And when driving in the city, the system will be practically useless, since it is deactivated when the speed drops to 40 km/h.
