Rear window defroster
Rear window defroster switch
The rear window defroster consumes a lot of
power. You should therefore switch it off as
soon as the window is clear. The rear window
defroster otherwise switches off automati-
cally after 12 minutes.
X Start the engine.
X To switch on/off: press the0071switch.
The indicator lamp in the 0071button
comes on when the rear window defroster
is switched on.
If the indicator lamp in the 0071rear window
defroster button flashes, the on-board volt-
age is too low. The rear window defroster has
switched off prematurely or cannot be acti-
vated.
X Switch off any consumers that are not
required, e.g. reading lamps or interior
lighting.
If enough on-board voltage is available again
within 30 seconds, the rear window defroster
automatically switches on again. It otherwise
remains switched off. Switching air-recirculation mode on/
off
Important safety notes When you switch on air-recirculation mode,
the windows could fog up more quickly, in
particular at low outside temperatures. Only switch on air-recirculation mode for a short
time.
You can deactivate the intake of fresh air if
unpleasant odors enter the vehicle from out-
side. The air inside the vehicle will only be
circulated.
Heating/air-conditioning system
Air-recirculation mode switches off automat-
ically after about 10to 30 minutes, depending
on the outside temperature.
X Switch on climate control (Y page 116).
X To switch on/off: press the008Aswitch.
If the indicator lamp in the 008Abutton
lights up, air-recirculation mode is acti-
vated.
Rear-compartment heating/rear-com-
partment air conditioning On vehicles with a rear-compartment heating
and air-conditioning system, you can acti-
vate/deactivate air-recirculation mode for
the rear-compartment climate control.
X
Switch on climate control (Y page 116).
X To activate: set the temperature control of
rear-compartment heating
0087(Y page 115) or rear-compartment air
conditioning system 0044(Ypage 116) to the
center position.
Only one of the two climate control sys-
tems in the rear compartment is activated
and is in air-recirculation mode.
X To deactivate: turn the temperature

conditioning system 0044(Ypage 116) clock-
wise or counterclockwise. Only change the

DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, for example in
enclosed spaces or if the vehicle gets stuck
in snow. There is a risk of fatal injury.
Switch the auxiliary heating off in enclosed
spaces without extraction systems, e.g. in
garages. If the vehicle is stuck in snow and
you have to leave the auxiliary heating run-
ning, keep the exhaust pipe and the area
around the vehicle free of snow. To ensure an
adequate supply of fresh air, open a window
on the side of the vehicle that is not facing
into the wind. G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot, e.g.
the exhaust system. Flammable material such
as leaves, grass or twigs may ignite if they
come into contact with hot parts of the
exhaust system. There is a risk of fire.
When the auxiliary heating is switched on,
make sure that no flammable material can
come into contact with hot vehicle compo-
nents.
! 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 other-
wise 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:
R hot-water auxiliary heater is done via the
on-board computer and with the auxiliary
heating button in the control panel
(Y page 124) or with the remote control
(Y page 125).
R auxiliary warm-air heater is done via the
timer above the overhead control panel
(Y page 127).
The auxiliary heating works independently of
the engine and supplements the climate 122
Operating the auxiliary heating systemClimate control

control system in the vehicle. The auxiliary
heating heats the air in the vehicle interior to
the temperature set.
If your vehicle is equipped with a hot-water
auxiliary 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 (Y page 130) of
the auxiliary heating supports the climate
control system when the engine is running
and the outside temperature is low.
You can use the auxiliary heating at an out-
side temperature of up to 39 ‡ (4 †). At an
outside temperature above 39 ‡ (4 †) the
auxiliary heating system and the heater boos-
ter function switch off automatically. Heating time
The heating time operating the auxiliary heat-
ing when the vehicle is stationary without the
engine running depends on the outside tem-
perature. Outside tempera-
ture Heating time
Above 23 ‡ (
00F85 †) Approx. 20 minutes
23 ‡ (
00F85 †) to 5 ‡
(00F815 †) Approx. 40 minutes
Below 5 ‡ (00F815 †) Approx. 50 minutes
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 maxi-
mum of 120 minutes to protect the starter
battery. Switching on the auxiliary heating is
then automatically disabled. You can, for
example, switch on the auxiliary heating with-
out the engine running if the outside temper-
ature is
00F85 ‡ (00F820 †) a maximum of two
times. If you try it again, the indicator lamps
in the 0084button (Y page 124) flash alter-
nately for approximately 2 minutes to signal switch-on interlock. The auxiliary heating can-
not be switched on without starting the
engine.
When the charge status of the starter battery
is sufficient again, the switch-on interlock will
be deactivated. To charge the starter battery,
let the engine run. The engine runtime
required to reach the necessary charge sta-
tus depends on the outside temperature.
Outside tempera-
ture Engine runtime

Setting the preselection time G
WARNING
The auxiliary heating must not be operated if
there are highly flammable substances
nearby or in enclosed spaces without an
extraction system. Make sure that the auxili-
ary heating is not switched on automatically
by the timer in such places. If this possibility
exists, deactivate the respective programmed
time.
You can set three preselection times using
the timer.
Observe that when setting the preselection
time, this does not correspond to the switch-
on time but to the switch-off or departure
time. The auxiliary heating system starts up
automatically and runs for the operating dura-
tion set prior to departure.
Example: For a planned departure time of
7:00 a.m., you should also set the preselec-
tion time to 7:00 a.m. If the operating dura-
tion is preset to 40 minutes, for example, the
auxiliary heating starts up at 6:20 a.m.
If an identical time (time and day) is set in the
preselection memory, only the last time set is
saved. After a malfunction or if the battery has been
disconnected, you must set the preselection
times again. You can find further information
on malfunctions in the "Problems with the
