GWARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot, e.g.
the exhaust system.
Flammable materials such as leaves, grass or
twigs may ignite if they come into contact
with:
Rhot parts of the exhaust system
Rthe exhaust gas itself
There is a risk of fire.
When the auxiliary heating is switched on,
make sure that:
Rno flammable materials come into contact
with hot vehicle components
Rthe exhaust gas can escape from the
exhaust pipe unhindered
Rthe exhaust gas does not come into contact
with flammable materials.
!Turn on the auxiliary heating at least once a
month for approximately 10 minutes. The
auxiliary heating could otherwise be dam-
aged.
!Make sure that the flow of hot air is not
blocked. The auxiliary heating will otherwise
overheat and switch off.
Your vehicle may be equipped with either an
auxiliary hot-water heater or an auxiliary warm-
air heater. Adjustment and operation of the:
Rhot-water auxiliary heater is done via the on-
board computer and with the auxiliary heating
button in the control panel (
Ypage 107) or
with the remote control (Ypage 108).
Rauxiliary warm-air heater is done via the timer
above the overhead control panel
(
Ypage 112).
The auxiliary heating works independently of the
engine and supplements the climate control
system in the vehicle. The auxiliary heating
heats the air in the vehicle interior to the tem-
perature set.
If your vehicle is equipped with a hot-water aux-
iliary heater, the auxiliary heating also keeps the
coolant warm. This way, the load on the engine
is minimized and fuel is saved.
The heater booster function (
Ypage 110) of the
auxiliary heating supports the climate control system when the engine is running and the out-
side temperature is low.
You can use the auxiliary heating at an outside
temperature of up to 39 ‡ (4 †). At an outside
temperature above 39 ‡ (4 †) the auxiliary
heating system and the heater booster function
switch off automatically.
Hot-water auxiliary heating
Heating time
The heating time when operating the auxiliary
heating with the vehicle is stationary without the
engine running depends on the outside temper-
ature and the electrical consumers switched on.

Below 5‡
( Ò 15 †)Approx.
50 minutes2
You can then switch on the auxiliary heating
again.
If you do not start the engine for a while, the total
duration of heating is limited to a maximum of
120 minutes to protect the starter battery.
Switching on the auxiliary heating is then auto-
matically disabled. You can, for example, switch
on the auxiliary heating without the engine run-
ning if the outside temperature is Ò5‡( Ò20 †) a
maximum of two times. If you try it again, the
indicator lamps in the ybutton
(
Ypage 107) flash alternately for approximately
2 minutes to signal switch-on interlock. The aux-
iliary heating cannot be switched on without
starting the engine.
When the condition of charge of the starter bat-
tery is sufficient again, the switch-on interlock
will be deactivated. To charge the starter bat-
tery, let the engine run. The engine run time
required to reach the necessary condition of
charge depends on the outside temperature and
on the electrical consumers switched on.

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

Replacing the remote control battery
GWARNING
Batteries contain toxic and corrosive substan- ces. If batteries are swallowed, it can result in
severe health problems. There is a risk of fatalinjury.
Keep batteries out of the reach of children. If
a battery is swallowed, seek medical attention
immediately.
HEnvironmental note
Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately and recycled to protect the
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.
