General information about
heaters
The parking heater can be started
immediately or set with two different start
times using TIMER 1 and TIMER 2. Here,
start time refers to the time the car should be
heated and ready. The car's electronic
system calculates when heating should be
started based on the outside temperature.
There will be no heating if the outdoor
temperature exceeds 25°C. At temperatures
of –7°C and below, the maximum running
time of the parking heater is 60 minutes.
WARNING!
The car must be outdoors if using petrol
and diesel heaters.
Activating the heater
1. Enter the time when the car is to be
used. Press RESET (C) to enter the
hours and minutes when the car is to be
used.
2. Press RESET again. The timer is
activated.
Press RESET button to activate the Timer.
• The timer is activated: ON lamp lights
with a steady glow.
• The heater operates: ON lamp flashes.
Parking on a hill
If the car is parked on a steep incline, the
front of the car should point downhill to
ensure that there is a
supply of fuel to the parking heater.
Heater direct start

"DIRECT START".
2. Press the RESET button (C) to make
ON and OFF selections available.

The heater will now run for 60 minutes.
The passenger compartment will begin
to heat up as soon as the engine
coolant has reached a temperature of
38°C
Immediate stop of heater
1. Use the thumb wheel to scroll to
"DIRECT START".
2. Press the RESET button (C) to make
ON and OFF selections available.

Battery and fuel
If the battery is not sufficiently charged or the
petrol level is too low, the parking heater will
be switched off automatically. A message
appears in the information display. Confirm
the message by pressing the READ button
(A).
IMPORTANT!
Repeated use of the parking heater
combined with short journeys may
discharge the battery and impair starting.
In order to ensure that the generator has
time to produce the energy required by
the heater without discharging the battery,
if the heater is used regularly the car must
be driven for a period equalling the time
during which the heater has been active.
