Please also observe the following breaking-in
notes:
In certain handling and driving safety systems,
R
the sensors adjust automatically while a cer-
tain distance is being driven after the vehicle
has been delivered or after repairs. Full sys-
tem effectiveness is reached only when this
teaching-in process has concluded.
Brake pads, brake disks and tires that are
R
either new or have been replaced achieve opti-
mum braking effect and grip only after driving
several hundred kilometers. Compensate the
reduced braking effect by applying greater
force to the brake pedal.

in the driver's footwell

footwell.
Always install the floor mats securely
#
and as prescribed in order to ensure that
there is always sufficient room for the
pedals.
Do not use loose floor mats and do not
#
place floor mats on top of one another.

Driving and parking 151
& WARNING Risk of accident if the vehicle is
switched off while driving
If you switch off the vehicle while driving,
safety functions are restricted or no longer
available.
This may affect the power steering system and
the brake force boosting, for example.
You will need to use considerably more force
to steer and brake, for example.
Do not switch off the vehicle while driv-
#
ing.
& DANGER Risk of death caused by exhaust
gases
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases is hazardous to health
and leads to poisoning.
Never leave the engine or, if present, the
#
auxiliary heating running in an enclosed
space without sufficient ventilation.
