Have the system checked by a specialised
workshop.
The drive proles or vehicle systems do not
behave as expected

Please note that dierent vehicle systems are

Braking system
Information about the brakes
During the rst 200 to 300 km, new brake
pads do not provide maximum braking power
and still have to “settle” ››› . When running
in the brake pads, the emergency braking
distance is longer than after they have been
run in. During the run-in, avoid sharp braking
and situations that place a lot of demand on
the brakes, e.g. driving too close to another
vehicle.
Brake pad wear depends to a large extent on
the conditions in which the vehicle is used, and
driving style. If the vehicle is frequently used
in city
traic and for short distances, or for
sporty driving, brake pad thickness should be
checked regularly at a specialist workshop.
Driving with wet brakes, e.g. after driving
through water, in heavy rain or after washing
the vehicle, braking performance may be af-
fected by wet brake discs, or even frozen discs
in winter. The driver should be ready to brake
harder.
If the brake discs and pads have a layer
of salt on them, the braking performance is
reduced and the braking distance increases.
When driving on salted roads without brak-
ing for some time, the layer of salt should
be removed by carefully applying the brakes
a few times ›››
. Braking intensity should
be higher than the deceleration achieved by
brake energy recuperation, in order to clean
o the layer of salt with the brake pad friction.
Corrosion on the brake discs and dirt on the
brake pads increase if the vehicle is left unused
for a long time, if it is not driven for many kil-
ometres or the brakes are used insuiciently.
If, due to the energy recuperation eect, the
brakes are not used, or are rarely used, or if
there is corrosion, it is advisable to clean the
discs and pads by braking hard several times
when driving at high speeds. When doing so,
select gear N, so that energy recuperation is
not used when braking. Make sure that you do
not endanger any other vehicles or road users

WARNING
Driving with worn brake pads or a defective
brake system can lead to accidents and seri-
ous injuries.
•
If you suspect that the brake pads are worn
or that the brake system is faulty, have the
brake pads checked immediately by a spe-
cialist workshop and replaced if they are
worn.
WARNING
The braking performance of new brake pads
is not optimal.
•
During the rst 300 km, new brake pads do
not provide maximum braking power and still
have to “settle”. This can be counteracted by
applying more pressure to the brake pedal.
•
When brake pads are new, drive with extra
care to reduce the risk of accidents, serious
injury or loss of control of the vehicle.
•
Only perform hard braking to clean the
brake system when permitted by the traic
situation. Do not endanger the occupants of
other vehicles. Accident hazard!
•
When running in new brake pads, do not
drive too close to other vehicles or cause sit-
uations that would require the brakes to be
applied heavily.
