Safety and Security Driving and safety systems Braking At the instant one of the wheels is about to lock up, a slight pulsation can be felt in the brake pedal, indicating that the ABS is in the regulating mode. Keep firm and steady pressure on the brake pedal while experiencing the pulsation. Continuous, steady brake pedal pressure yields the advantages provided by the ABS, namely braking power and the ability to steer the vehicle. The pulsating brake pedal can be an indication of hazardous road conditions and functions as a reminder to take extra care while driving. Emergency brake maneuver Keep continuous full pressure on the brake pedal. LOW RANGE- ABS During off-road driving, a special low range system for the ABS is operational with transmission in LOW RANGE mode ( page 125). When applying the service brakes at speeds below approximately 18 mph (30 km/h), the front wheels are locked cyclically to shorten the braking distance (dig-in effect). This affects steering the vehicle. i With the ABS malfunctioning, the BAS, the EBP, ESP, and the 4-ETS are also switched off. Normal driving and braking functions are still available. 77
