9-9 Driving and operatingBrakesFoot brakeThe brake system comprises twoseparate brake circuits.If one brake circuit should fail, thevehicle can still be braked with thesecond remaining circuit.If this happens, the brake pedal mustbe fully depressed with greater pedalpressure. The distance required forbraking will be greater. Seek theassistance of a workshop.In order to utilise the full pedal travel,particularly in the event of a brakecircuit fault, there must be no mats inthe area of the pedals 3 9-1.With the engine stopped, the brakeservo assistance is discontinued afterthe brake pedal has been depressedonce or twice. The braking effect isnot reduced, but increased footpressure will be necessary. Takeextra care if the vehicle is beingtowed.Brake system control indicator 3 5-9.Anti-lock Brake System(ABS) uThe ABS prevents the wheels fromlocking during heavy braking.It starts to regulate braking pressureas soon as a wheel shows a tendencyto lock. The vehicle remainssteerable, even during heavy braking,e.g. on bends or when swerving toavoid an obstacle. Even in the case ofextreme braking, ABS makes itpossible to drive round obstacleswithout releasing the foot brake.ABS control indicator 3 5-9.FaultHave the cause of the fault remediedby a workshop.Parking brakeAlways apply the parking brake firmlywithout actuating the release button.Apply as fully as possible on uphill ordownhill inclines.To release the parking brake, pressand hold the button, pull the lever upslightly and lower lever while holdingthe button in.To reduce the operating forces of theparking brake, depress the foot brakeat the same time.Brake system control indicator 3 5-9.CautionIf there is a fault in the ABS, thewheels may lock during heavybraking. This may cause the vehicleto swerve.
