Brake servo
If the car is rolling or is being towed with the
engine turned off, the brake pedal must be
depressed about 5 times harder than when the
engine is running. If the brake pedal is
depressed when the engine is started, you will
feel the pedal drop. This is normal and due to
the brake servo becoming active. This may be
more noticeable if the car has Emergency
Brake Assistance (EBA).
WARNING
The brake servo only works when the engine
is running.
NOTE
If braking with the engine switched off,
press the brake pedal sharply once, not
repeatedly.
Brake circuits
This symbol illuminates if a brake
circuit is not working.
If a fault should occur in one of the
circuits, it is still possible to brake
the car. The brake pedal will travel further and
may feel softer than normal. Harder pressure
on the pedal is needed to produce the normal
braking effect.
Dampness can affect braking
characteristics
Brake components become wet when the car
is driven in heavy rain, through pools of water
or when the car is washed. This may alter brake
pad friction characteristics so that there is a
delay before braking effect is noticed.
Press the brake pedal lightly from time to time
if driving for long stretches in rain or slushy
snow, as well as after setting off in very damp
or cold weather. This warms up the brake pads
and dries off any water. This precaution is also
recommended before parking the car for a long
period in such weather conditions.
If the brakes are used heavily
When driving in the Alps or other roads with
similar characteristics, the car's brakes are
heavily loaded even if the brake pedal is not
being depressed especially hard.
Because speed is often low, the brakes are not
cooled as effectively as when driving on flat
roads at higher speed.
So as not to overload the brakes, shift down
when driving downhill instead of using the foot
brake. Use the same gear driving downhill as
you would use driving uphill. This uses engine
braking more efficiently so the foot brake is
only required for brief periods.
06 Starting and driving
Brake system
Bear in mind that driving with a trailer puts an
additional load on the car's brakes.
Anti-lock braking system - ABS
The anti-lock braking system
(ABS) prevents the wheels from
locking up during braking.
This means the ability to steer is
maintained and it is easier to swerve to avoid a
hazard for example.
After the engine has been started, the ABS will
perform a brief self-test at a speed of
about 20 km/h. This can be felt and heard as
pulses 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. Do
not release the pressure on the pedal.
Practice braking with the ABS system in a traf-
fic-free area and in different weather condi-
tions.
