active head restraints tilt forwards
slightly. The head is more effectively
supported by the head restraint and
the risk of whiplash injury is reduced.
Active head restraints can be
recognised by the word
ACTIVE.

Radio remote control Used to operate:
■ Central locking system,
■ Anti-theft locking system,
■ Anti-theft alarm system,
■ Power windows.
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 it 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 remote control while not in range,
which will require re-
synchronisation,
■ Overloading the central locking by operating at frequent intervals, the
power supply is interrupted for
a short time,
■ Interference from higher-power radio waves from other sources.

Alarm
When triggered, the alarm gives off
an
acoustic signal (horn) and a visual
signal (hazard warning flashers). The
number and duration of which are
stipulated by legislation.
The alarm can be silenced by
pressing a button of the radio remote
control or by switching on the ignition.

deactivated at the same time. Immobiliser
The system checks whether the
vehicle
is allowed to start with the key

key is recognised, the vehicle can be
started.
The electronic immobiliser activates
itself automatically after the key has
been removed from the ignition
switch or when the engine is switched
off by pressing the Start/Stop button.
If the control indicator A flashes
when the ignition is on, there is a fault
in the system; the engine cannot be
started. Switch off the ignition and
then repeat the start attempt.
If the control indicator continues
flashing, attempt to start the engine
using the spare key and seek the
assistance of a workshop.
If control indicator illuminates after
the engine has started, there is a fault
in the engine electronics or
transmission electronics 3 88,
3 135, 3 139, or there is water in the
diesel fuel filter 3 101. Note
The immobiliser does not lock the
doors. You should always lock the
vehicle
after leaving it and switch on
the anti-theft alarm system 3 32,
