& 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 Wearing out the brake linings by
continuously depressing the brake pedal
Do not depress the brake pedal contin‐
#
uously whilst driving.
To use the 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.

Limited braking effect on salt-treated roads:
Due to salt build-up on the brake discs 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
To prevent salt build-up:
Brake occasionally while paying attention to
R
the traffic conditions
Carefully depress the brake pedal at the end
R
of the journey and when starting the next
journey
