& DANGER Risk of fatal injuries due to
exhaust gases
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Breathing in
these exhaust gases is hazardous to health
and results in poisoning.
Never leave the engine and, if present,
#
the stationary heater, running in an
enclosed space without sufficient venti-
lation.
& WARNING Risk of skidding and of an acci-
dent 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 surfa-
#
ces to increase the engine braking
effect.
& DANGER Risk of fatal injury due to poison-
ous 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, for example, if the vehicle
gets stuck in the snow.
Keep the tailpipe and the area around
#
the vehicle free from snow when the
engine or the stationary heater is run-
ning.
Open a window on the side of the vehicle
#
facing away from the wind to ensure an
adequate supply of fresh air.
& WARNING Risk of accident due to the
brake system overheating
If you leave your foot on the brake pedal when
driving, the brake system may overheat.
This increases the braking distance and the
brake system can even fail.
Never use the brake pedal as a footrest.
#
Driving and parking 177
Do not depress the brake pedal and the
#
accelerator pedal at the same time while
driving.
* NOTE Engine damage due to excessively
high engine speeds
The engine will be damaged if you drive with
the engine in the overrevving range.
Do not drive with the engine in the over-
#
revving range.
* NOTE Causing wear to the brake linings by
permanently depressing the brake pedal
Do not permanently depress the brake
#
pedal while driving.
To use braking effect of the engine, shift
#
to a lower gear in good time.
