Brake booster
The brake booster amplifies the pressure you ap-
ply to the brake pedal. It only operates while the
engine is running or when the ignition is switched
on (plug-in hybrid drive*) .
A WARNING
- Only apply the brakes for the purpose of
cleaning the brake system when road and
traff ic conditions permit. You must not en-
danger other road users. This increases the
risk of an accident .
-
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident.
- Depending on the vehicle equipment, the
brake pedal may be pulled downward when
the vehicle automatically init iates braking.
- Never place objects in the driver's footwell.
An object could end up in the area around
the pedals and prevent you from using
them. You would not be able to use the ped-
als if sudden driving or braking mane uvers
were needed, which increases the risk of an
accident.
- Only use floor mats that do not obstruct the
area around the pedals and that can be se-
curely fastened in the footwe ll s.
- To reduce the risk of injury, do not place
your foot under the brake pedal.
(Llj) Note
- Never let the brakes " rub" by pressing the
pedal lightl y when braking is not actually
necessary. This causes the brakes to over-
heat and increases braking distance and
causes wear.
- Before driving on a long stretch with steep
slopes, reduce your speed and shift to the
next lower gear This makes use of the en-
gine braking effect and relieves the brakes.
If you need to brake addit ionally, brake in
intervals and not cont inuously.
Intelligent Technology
(D Tips
- If the brake booster is not working, you
must press the brake pedal with much more
force than normal.
- If you retrofit your vehicle with a front spoil-
er, wheel covers or simi lar items, make sure
that the air flow to the front wheels is not
interrupted. Otherwise the brake system
can become too hot.
Electromechanical
steering
The electromechanical steering supports the
driver's steering movements.
Power steering adapts electronically based on
the vehicl e speed.
