& 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.
Open a window on the side of the vehi‐
#
cle 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 over‐
heat.
This increases the braking distance and the
brake system may even fail.
Never use the brake pedal as a footrest.
#
Do not depress the brake pedal and the
#
accelerator pedal at the same time
while driving.
* 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.
* NOTE Damage to the drivetrain and
engine when pulling away
Do not warm up the engine while the
#
vehicle is stationary. Pull away immedi‐
ately.
Avoid high engine speeds and driving at
#
full throttle until the engine has reached
its operating temperature.
* NOTE Damage to the catalytic converter
due to non-combusted fuel
The engine is not running smoothly and is
misfiring.
Non-combusted fuel may get into the cata‐
lytic converter.
Only depress the accelerator pedal
#
slightly.
Have the cause rectified immediately at
#
a qualified specialist workshop.
Notes on driving on salt-treated roads
The braking effect is limited on salt-treated
roads.
Therefore, observe the following notes:
due to salt build-up on the brake disks and
R
brakepads, the braking distance can increase
considerably or result in braking only on one
side
maintain a much greater safe distance to the
R
vehicle in front
