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 immobiliser is part of the ignition
switch and checks whether the
vehicle is allowed to be started with

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. 2 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.

108Climate controlAuxiliary heater
Coolant heater The Eberspächer 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.
