& WARNING Risk of accident due to the
ignition being switched off whilst the
vehicle is in motion
If you switch off the ignition whilst the vehi‐
cle is in motion safety-relevant functions will
be restricted or no longer available. This may
effect the power steering system and brake
force boosting, for example.
You will need to use considerably more force
to steer and brake.
Do not switch off the ignition whilst the
#
vehicle is in motion.
& WARNING Risk of exhaust gas poisoning
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases causes poisoning.
Never leave the engine 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 if the vehicle gets 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.
Driving and parking 133
Open a window on the windward side of
#
the vehicle to ensure an adequate sup‐
ply of fresh air.
& WARNING Risk of accident or injury due
to driving under the influence of alcohol
and drugs
Driving and the consumption of alcohol
and/or drugs are an extremely dangerous
combination. Even small quantities of alcohol
or drugs can compromise your reflexes, per‐
ception and judgment.
The possibility of a serious or even fatal acci‐
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or
#
allow anyone to drive who has been
drinking alcohol or taking drugs.
