Anti-lock braking system (ABS) (Renault Symbol 1)

Anti-lock braking system prevents slippage (blocking) wheels on the road surface during sudden braking, thereby eliminating skidding of the car and contributing to a significant increase in its stability and controllability. The system is automatically switched on when the engine is started. The switching mode is controlled by a lamp in the instrument cluster, which should go out after a few seconds.

If the lamp does not go out or lights up while driving, then there is a malfunction in the ABS system. In this case, the car's braking ability is fully preserved, but without the anti-lock function of the wheels.

The ABS system starts working when the vehicle reaches a speed of 3–5 km/h.
