204 Driving and parking
This jeopardises the operating and road
safety of the vehicle.
Stow all objects in the vehicle securely
#
so that they cannot get into the driver's
footwell.
Always fit 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.
& WARNING Risk of accident due to incor‐
rect footwear
Incorrect footwear includes, for example:
shoes with platform soles
R
shoes with high heels
R
slippers
R
Always wear suitable footwear so that
#
you can operate the pedals safely.
& WARNING Risk of accident if the ignition
is switched off while driving
If you switch off the ignition while driving,
safety functions are restricted or no longer
available.
You will then need, for example, to use con‐
siderably more force to steer and brake.
Do not switch off the ignition 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 venti‐
lation.
& WARNING Risk of skidding and of an
accident due to shifting down on slippery
road surfaces
If you shift down on slippery road surfaces to
increase the engine braking effect, the drive
wheels may lose traction.
Do not shift down on slippery road sur‐
#
faces to increase the engine braking
effect.
& DANGER Risk of fatal injury due to poi‐
sonous exhaust gases
If the tailpipe is blocked or sufficient ventila‐
tion is not possible, poisonous exhaust gases
such as carbon monoxide may enter the vehi‐
cle. This is the case when the vehicle
becomes stuck in snow, for example.
Keep the tailpipe and the area around
#
the vehicle free from snow when the
engine or the stationary heater are run‐
ning.
