When the engine is off, no vacuum is created and each time you press the brake pedal, the additional braking force is reduced, so you should not press the brake pedal unnecessarily.
If the brakes fail while driving, the parking brake may be applied (see below).
Attention: Do not keep your foot on the brake pedal when the car is moving, because. this leads to heating and premature wear of the brake mechanisms, as well as to an increase in the braking distance. When driving downhill, do not use the brakes for too long, instead use engine braking by downshifting. After washing the vehicle, driving in the rain, or driving in water, dry the brakes by lightly depressing the brake pedal and holding it until the brake performance returns to normal.
The brake system is divided diagonally into two independent hydraulic circuits. If one of the circuits fails (for example, as a result of a seal failure, this is felt by the softness of the pedal) the second one continues to function normally, providing adequate braking of the car, but with an increased braking distance.
A low brake fluid level, as well as worn brake pads, is indicated by the activation of the relevant warning lamps in the instrument cluster and the appearance of corresponding messages on the display in the instrument cluster (see Section 13).
Anti-lock brake systems (ABS), stability control (ESP) and their functions
The ABS system constantly monitors the speed of rotation of the wheels of the car and prevents them from blocking by repeatedly modulating the hydraulic pressure in the brake system. Thus, even with the brake pedal fully depressed, the car remains steerable. The anti-blocking system is activated automatically every time the ignition is turned on, which is confirmed by the inclusion of the corresponding K / L in the instrument cluster (see Section 13). After successful passing of self-diagnostics ABS K/L is switched off. If K / L does not go out, then the ABS is faulty. In this case, the service brake system can function normally.
During ABS operation (it is felt by the pulsation of the brake pedal) do not change the pressure on the brake pedal, because. this will prevent the ABS system from working at its maximum efficiency.
Always remember the following precautions:
- even with the ABS system, the car cannot be stopped instantly, - keep a safe distance;
- always slow down when cornering as the ABS system cannot prevent the occurrence of an accident at high speed;
- when driving on rough roads/puddles, braking with ABS may cause a longer braking distance than without ABS;
- do not neglect the general rules of road safety.
Based on the ABS system, the system of dynamic stabilization of vehicle stability is based (ESP). It recognizes driving conditions that lead to reduced stability (for example, if there are prerequisites for skidding), and keeps the vehicle on course by reducing engine torque and braking individual wheels.
Note: ESP cannot operate outside physical limits, so do not rely on this feature to work. If the ABS fails, the ESP is automatically deactivated.
The ESP system is activated automatically every time the ignition is turned on, which is confirmed by the inclusion of the corresponding K / L in the instrument cluster (see Section 13). After successful passing of self-diagnostics ESP К/Л is switched off. If a malfunction of the ESP is detected, the K / L does not go out, a corresponding message may appear on the display in the instrument cluster (see Section 13), and the ESP system itself is disabled. Blinking R/L ESP indicates operation of this system.
In the presence of the ESP system, there is a function to counteract wheel slip (ASR), preventing loss of grip (slippage) driving wheels with the road at the time of the start of movement or during acceleration. The ASR OFF switch is located in the center console (24 in illustration 12.1) and is designed to forcibly disable this function and then enable it when the engine is running. Turning off the ASR function may be required when driving in deep snow or loose ground, or when freeing a stuck vehicle "swinging". Once it is no longer necessary to disable the ASR feature, it should be enabled for added security.
The distribution of braking forces between the wheels, depending on the vehicle load, is controlled by the corresponding function of the electronic differential lock (EDS), also powered by ABS. Under excessive load, EDS can be disabled to prevent overheating of the brakes, emergency brake assist function (BAS) determines the moment of hard braking by measuring the speed of pressing the pedal. As long as the pedal remains depressed, the system provides maximum braking performance.
The emergency brake assist function can reduce the stopping distance in critical situations.
Hill start assistant (recoil system, NNS) facilitates acceleration when driving uphill. The system maintains the brake pressure generated by pressing the brake pedal for approximately 2 seconds after releasing the brake pedal. In this way, the driver can take their foot off the brake pedal and onto the accelerator pedal and start uphill without using the parking brake. Brake pressure decreases gradually as you press on the gas pedal. In the event that the car does not move within two seconds, it will begin to roll back. The rollback system is active from 5% uphill if the driver's door is closed. The system operates in both forward and reverse motion. When driving downhill, the system does not work.
Parking brake
The parking brake lever is located between the front seats. To apply the parking brake, depress the brake pedal and pull the lever up; to release the parking brake, depress the brake pedal, press the button on the end of the lever while pulling it up slightly, and then lower the lever.
Note: Do not use a transmission in gear instead of a parking brake.
When stopping on an incline, park your vehicle as close to the sidewalk or shoulder as possible and steer your wheels toward the center of the road so that if the vehicle is accidentally moving backwards, the front wheels would hit the curb.
When stopping on an incline, park your vehicle as close to the curb or curb as possible and steer your wheels toward the curb so that if the vehicle accidentally moves forward, the front wheels would hit the curb.
At each start of the engine, check the K / L of the brake system (see Section 13) - with the parking brake engaged, the K/L should be on, and after it is released, the K/L should go out. If you start driving with the parking brake applied, after three seconds of driving at a speed of more than 6 km / h, an audible signal sounds, and the message in the instrument cluster display may appear "Remove from manual brakes!"
