Driving tips
cannot enter into the driver's floor area. Use
floor mats that are suitable for the vehicle and
can be safely attached to the floor. Do not use
loose floor mats and do not layer several floor
mats. Make sure that there is sufficient clear‐
ance for the pedals. Ensure that the floor mats
are securely fastened again after they were re‐
moved, e.g., for cleaning.◀
Driving in wet conditions
When roads are wet, salted, or in heavy rain,
gently press the brake pedal every few miles.
Ensure that this action does not endanger
other traffic.
The heat generated during braking dries brake
discs and brake pads and protects them
against corrosion.
In this way braking efficiency will be available
when you need it.

WARNING
Light but consistent brake pressure can
lead to high temperatures, brakes wearing out
and possibly even brake failure. There is a risk
of an accident. Avoid placing excessive stress
on the brake system.◀
WARNING
In idle state or with the engine switched
off, safety-relevant functions, e.g., engine
braking effect, braking force boost and steer‐
ing assistance, are restricted or not available at
all. There is a risk of an accident. Do not drive
in idle state or with the engine switched off.◀
Drive long or steep downhill gradients in the
gear that requires least braking effort. Other‐
wise, the brakes may overheat and reduce
brake efficiency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if needed.

Things to remember when driving

Brake disc corrosion
Corrosion on the brake discs and contamina‐
tion on the brake pads are increased by the fol‐
lowing circumstances:
▷ Low mileage.
▷ Extended periods when the vehicle is not
used at all.
▷ Infrequent use of the brakes.
▷ Aggressive, acidic, or alkaline cleaning
agents.
Corrosion buildup on the brake discs will cause
a pulsating effect on the brakes in their re‐
sponse - generally this cannot be corrected.
Condensation water under the parked
vehicle
When using the automatic climate control,
condensation water develops and collects un‐
derneath the vehicle.
