06 Starting and driving Brake system06169Brake servoIf the car is rolling or is being towed with theengine turned off, the brake pedal must bedepressed about 5 times harder than when theengine is running. If the brake pedal isdepressed when the engine is started, you willfeel the pedal drop. This is normal and due tothe brake servo becoming active. This may bemore noticeable if the car has EmergencyBrake Assistance (EBA).WARNINGThe brake servo only works when the engineis running.NOTEIf braking with the engine switched off,press the brake pedal sharply once, notrepeatedly.Brake circuitsThis symbol illuminates if a brakecircuit is not working.If a fault should occur in one of thecircuits, it is still possible to brakethe car. The brake pedal will travel further andmay feel softer than normal. Harder pressureon the pedal is needed to produce the normalbraking effect.Dampness can affect brakingcharacteristicsBrake components become wet when the caris driven in heavy rain, through pools of wateror when the car is washed. This may alter brakepad friction characteristics so that there is adelay before braking effect is noticed.Press the brake pedal lightly from time to timeif driving for long stretches in rain or slushysnow, as well as after setting off in very dampor cold weather. This warms up the brake padsand dries off any water. This precaution is alsorecommended before parking the car for a longperiod in such weather conditions.If the brakes are used heavilyWhen driving in the Alps or other roads withsimilar characteristics, the car's brakes areheavily loaded even if the brake pedal is notbeing depressed especially hard.Because speed is often low, the brakes are notcooled as effectively as when driving on flatroads at higher speed.So as not to overload the brakes, shift downwhen driving downhill instead of using the footbrake. Use the same gear driving downhill asyou would use driving uphill. This uses enginebraking more efficiently so the foot brake isonly required for brief periods.Bear in mind that driving with a trailer puts anadditional load on the car's brakes.Anti-lock braking system - ABSThe anti-lock braking system(ABS) prevents the wheels fromlocking up during braking.This means the ability to steer ismaintained and it is easier to swerve to avoid ahazard for example.After the engine has been started, the ABS willperform a brief self-test at a speed ofabout 20 km/h. This can be felt and heard aspulses in the brake pedal.To get the most out of the ABS:1. Depress the brake pedal with full force.Pulses will be felt.2. Steer the car in the direction of travel. Donot release the pressure on the pedal.Practice braking with the ABS system in a traf-fic-free area and in different weather condi-tions.
