& WARNING Risk of accident when the
ignition is switched off due to steering
wheel lock
If you switch off the ignition while the vehicle
is at a standstill, the steering wheel lock
engages in vehicles with manual transmis‐
sion.
You can no longer steer the vehicle.
Turn on the ignition before rolling the
#
vehicle to deactivate the steering wheel
lock.
& WARNING Risk of accident when switch‐
ing off the ignition when driving
If you switch off the ignition 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 then need to use considerably more
force to steer and brake.
Do not switch off the ignition while driv‐
#
ing.
& DANGER Risk of fatal injuries due to
exhaust gases
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases is hazardous to health
and can lead to poisoning.
Never leave the engine running in an
#
enclosed space without sufficient venti‐
lation.
& DANGER Risk of fatal injuries 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, for example, if the vehi‐
cle is stuck in snow.
When the engine or the stationary
#
heater are running, keep the tailpipe
and the area around the vehicle clear of
snow.
Open a window on the side of the vehi‐
#
cle facing the wind to ensure an ade‐
quate supply of fresh air.

& WARNING Risk of accident due to over‐
heated brake system
If you rest your foot on the brake pedal during
while driving, the brake system may overheat.
This increases the braking distance and the
brake system may even fail.
Never use the brake pedal as a footrest.
#
Do not press the brake pedal and accel‐
#
erator pedal simultaneously while driv‐
ing.
On long and steep downhill gradients, you should
change down to a lower gear in good time. Take
particular note of this when driving a laden vehi‐
cle. By doing so, you will make use of the
engine's braking effect. This relieves the load on
the brake system and prevents the brakes from
overheating and wearing too quickly.
* 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.
