Braking and parking
Corrosion
Ther
e may be a tendency for corrosion to
form on the discs and dirt to build up on the
brake pads if the vehicle is used infrequently
or the brakes are not used very often.
If the brakes are not used frequently, or if rust
has formed on the disks, it is advisable to
clean off the pads and disks by braking firmly
a few times at a moderately high speed

F
ault in the brake system
If the brake pedal travel should ever increase
suddenly, this may mean that one of the two
brake circuits has failed. Drive immediately to
the nearest specialised workshop and have
the fault repaired. Drive there slowly and re-
member that you will have to apply more
pressure on the brake pedal and allow for
longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake fluid
level is monitored electronically.
Brake servo
The brake servo increases the pressure you
apply to the brake pedal. It works only when
the engine is running.
Electromechanical brake servo (eBKV)
The electromechanical brake servo only
works when the ignition is switched on and
optimises the force of the foot by increasing
the pressure that the driver exerts on the
brake pedal.
If the electromechanical brake servo is not
working, the brake pedal must be pressed
harder, as the braking distance increases due
to the lack of assistance from the servo brake.
WARNING
Any anomaly in the brake system can in-
cr
ease the braking distance, with the re-
sulting risk of an accident.
●
New brake pads and discs must be run in
and do not have the correct friction during
the first 200 km (124 miles). This reduced
braking capacity may be offset by pressing
on the brake pedal a little harder.
●
If you are driving on roads which have
been salted, braking effectiveness may be
decreased.
●
Brakes can overheat if used excessively
on slopes. Before driving down a long steep
slope, it is advisable to reduce speed and
change down into a lower gear or range.
Therefore, using the engine brake relieves
the brakes.
●
Gentle continuous braking causes the
brakes to overheat and the braking dis-
tance will increase. Apply and then release
the brakes alternately.
●
Apply the br
akes heavily to clean the
brake system only in a suitable traffic situa-
tion. Do not put other road users in danger:
there is risk of causing an accident.
●
Ensure the vehicle does not move while in
neutral, when the engine is stopped. The
braking distance is increased considerably
when the brake servo is not active.
●
If the brake is subjected to high stresses,
vapour bubbles may form in the brake sys-
tem's pipes. This reduces the efficiency of
the brakes.
●
Non-standard or damaged front spoilers
could restrict the airflow to the brakes and
cause them to overheat. Before purchasing
accessories please read the relevant in-
structions.
CAUTION
●
Ne
ver let the brakes “drag” by leaving
your foot on the pedal when it is not neces-
sary to brake. This overheats the brakes, re-
sulting in longer stopping distances and
greater wear.
●
Before driving down a long, steep gradi-
ent, it is advisable to reduce speed and se-
lect a lower gear. This makes use of engine
braking and relieves the brakes. If you still
have to use the brakes, it is better to brake
firmly at intervals than to apply the brakes
continuously.
