number and duration of alarm signals are stipulated by legislation.
If the vehicle battery is disconnected
or its power supply is interrupted, the
alarm siren will be triggered. First
deactivate the anti-theft alarm system
if the vehicle battery must be
disconnected.To silence the alarm siren (if
triggered) and therefore deactivate
the anti-theft alarm system, reconnect vehicle battery and unlock the vehicle
or switch on the ignition.
Immobiliser
The immobiliser is part of the ignition
switch and checks whether the
vehicle is allowed to be started with
the key being used.
The immobiliser is activated
automatically after the key has been removed from the ignition switch and
also if the key is left in the ignition
switch when the engine is turned off.
If the engine cannot be started, switch off the ignition and remove key, wait
approx. two seconds and then repeat
the start attempt. If start attempt is
unsuccessful, attempt to start the
engine using the spare key and seek
the assistance of a workshop.Notice
Radio Frequency Identification
(RFID) tags may cause interference with the key. Do not have it placednear the key when starting the
vehicle.
Notice
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 24,

Climate control119Rear air conditioning fan switch
The rear air conditioning fan assists
air flow to the rear passenger
compartment via the rear air vents.
Switch on the fan while the air
conditioning system is operating to
allow cooled and dehumidified (dried) air to be distributed.
The rate of air flow is determined by
the fan.
Auxiliary heater
Coolant heater The engine-independent, fuel-
powered coolant heater provides
rapid heating of the engine coolant to
enable heating of the vehicle interior
without the engine running.9 Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
Before starting or programming the
system to start, turn the vehicle's
climate control system to heat, set the
air distribution to V and turn the fan
on.
Switch off when not required. Heating stops automatically after the
programmed runtime. It will also
cease to operate if the vehicle fuel
level drops too low.
During operation, power from the
vehicle battery is used. The driving
time should therefore be at least as
long as the heating time. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
To ensure efficient performance,
briefly operate the auxiliary heater
once a month.
Control units
The timer or remote control unit turns the system on and off, and is used to
programme specific departure times.

range of 1000 metres. The range may
be reduced due to environmental
conditions and as the battery
becomes weaker.

lower part of the instrument panel,
beside the steering wheel.
The LED in the button confirms
operation.
Battery replacement
Replace the battery when the range
of the remote control is reduced or when the battery charge symbol
flashes.
Open the cover and replace the
battery (Type A: CR 2430, Type B: 2CR 11108, or equivalent), ensuring
