Note: The specifics of starting the engine on models with an ABS system when the battery is completely discharged are given in the subsection "Jump starting with an additional battery" chapters "User manual".
Description of the Anti-lock Braking System (ABS)
1. Anti-lock braking system (ABS) controls the pressure in the brake circuits of all four wheels, preventing the wheels from locking.
ABS allows:
- to avoid an obstacle with a high degree of confidence, even in the event of emergency braking;
- stop the vehicle during emergency braking while maintaining control and stability on the road, even on a curved trajectory.
2. The main function of the ABS system is to ensure the stability and control of the vehicle. However, the system cannot prevent the vehicle from skidding if the cornering speed limit is exceeded.
3. The ABS system consists of a hydraulic unit, an electronic ABS control unit, a master brake cylinder with a vacuum booster, wheel speed sensors, a relay and an "ABS" indicator.
4. Receiving signals from all sensors during braking, the electronic control unit determines which wheel is on the verge of locking. At this point, the electronic control unit activates the corresponding electromagnetic valve in the hydraulic unit to provide the required pressure in the brake circuit of the corresponding wheel.
5. The electronic control unit has self-diagnostic and emergency mode functions. When a malfunction is detected, the "ABS" indicator lights up on the instrument cluster and the corresponding malfunction code is entered into the control unit memory, then the system goes into emergency mode (ABS system shutdown).
6. The anti-lock braking system (ABS) is activated when the vehicle speed exceeds 10 km/h and deactivated when the speed is less than 5 km/h.
