24In briefTyre pressure monitoring
system
A pressure sensor is integrated in
each wheel to monitor tyre pressure.
Whilst driving, the current tyre
pressures appear in the Board
Computer menu.
Deviating tyre pressure is displayed
in the form of a message in the
Info-Display.
Tyre pressure monitoring system

Adaptive Forward Lighting
The system improves lighting of
curves and increases the headlight
range.
The beam pivots based on steering
wheel position and vehicle speed.
At higher speeds and continuous straight ahead travel, the beam
automatically raises slightly, thereby
increasing headlight range.
Adaptive forward lighting 3 110.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving. The filter
is cleaned by burning off the soot
particles at high temperature. This
process takes place automatically
under set driving conditions and may take up to 25 minutes. Fuel
consumption may be higher during
this period. The emission of smells
and smoke during this process is
normal.
Page 27 of 217
In brief25
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If the filter requires cleaning and
previous driving conditions did not
enable automatic cleaning, control
indicator ! flashes.

Keys, doors and windows27Radio remote control
Used to operate:■ Central locking system,
■ Anti-theft locking system,
■ Anti-theft alarm system,

The radio remote control has a range of approx. 5 metres. This range can
be affected by outside influences.
The hazard warning flashers confirm
operation.
Handle with care, protect from
moisture and high temperatures and
avoid unnecessary operation.
Fault
If the central locking system cannot
be operated with the radio remote
control, it may be due to the following:
■ Range exceeded,
■ Battery voltage too low,
■ Frequent, repeated operation of the
radio remote control while not in
range, which will require re-
synchronisation,
■ Overload of the central locking system by operating at frequent
intervals, the power supply is
interrupted for a short time,
■ Interference from higher-power radio waves from other sources.
Unlocking 3 31.
