At outside temperatures of up to 39 ‡(4 †) the
fuel-fired heater booster system heats the vehi-
cle interior as quickly as possible when the
engine is running.
The auxiliary heating automatically switches to
heater booster mode after the engine is started.
At an outside temperature above 39 ‡(4 †) the
auxiliary heating system and the heater booster
function switch off automatically.
If you switch off the engine without switching off
the heater booster function, the system will be
switched on the next time the engine is started (memory function).
iSwitch the auxiliary heating on or off with
the y button (Ypage 108).

environment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified spe-
cialist workshop or a special
collection point for used bat-
teries.
If the indicator lamp on the remote control
flashes red rapidly, the remote control battery is
discharged. You should replace the remote con-
trol battery.
You need a battery of the type CR2430, which
can be obtained at any qualified specialist work-
shop.

Operation with the timer
Important safety notes
GDANGER
If a switch-on time has been selected, the
auxiliary heating switches on automatically.
RIf the ventilation is insufficient, poisonous
exhaust gases can collect, in particular car-
bon monoxide. This is the case in enclosed
spaces, for example. There is a risk of fatal
injuries.
RIf highly flammable substances or flamma-
ble materials are nearby, there is a risk of a
risk of fire and explosion.
Always deactivate the preselected switch-on
times if you stop the vehicle in such or similar situations.
Use the timer to:
Ractivate and deactivate immediate heating
mode
Rset up to three switch-on times
Rset the operating duration to between 10 and
120 minutes or to continuous operation
Rset the heating level (preselected tempera-
ture) to a range between 10 and 30
