Brakes 165 X Vehicles with Telligent ® gearshift: on slippery road surfaces, also depress the clutch pedal. The engine braking effect cannot affect the ABS control system. The ABS off-road program can be activated for off-road driving. When braking at speeds of between approximately 40 and 15 km/h, the ABS off-road program allows the wheels to lock briefly. This reduces the braking dis- tance on corresponding surfaces. At speeds below approximately 15 km/h, ABS is deactivated and the wheels may lock. The steerability of the vehicle is impaired when the wheels are locked.
