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.

ically after about 10 to 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 activa-
ted.
Rear-compartment heating/rear-com-
partment air conditioning On vehicles with a rear-compartment heating
and air-conditioning system, you can acti-

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(Ypage 115) or rear-compartment air conditioning sys-

tems in the rear compartment is activated
and is in air-recirculation mode.
X To deactivate: turn the temperature con-
trol of rear-compartment heating 0087
(Y page 115) or rear-compartment air-con-
ditioning system 0044(Ypage 116) clock-
wise or counterclockwise. Only change the
temperature in small increments. Adjusting the air vents
Important safety notes
G
WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
The center and side air vents are adjustable.
On vehicles with a rear-compartment air-con-
ditioning system, you can also adjust the air
vents in the roof duct.
i For virtually draft-free ventilation, adjust
the sliders of the center air vents to the
center position.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior, please observe the following notes:
R keep the air inlet grille on the hood free of
blockages, such as ice, snow or leaves.
R never cover the vents or the ventilation
grilles in the vehicle interior. 120

G
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 materials such as leaves, grass or
twigs may ignite if they come into contact
with:
R hot parts of the exhaust system
R the exhaust gas itself
There is a risk of fire. When the auxiliary heating is switched on,
make sure that:
R no flammable materials come into contact
with hot vehicle components
R the exhaust gas can escape from the
exhaust pipe unhindered
R the 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 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 123) 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 con- trol system in the vehicle. The auxiliary heat-
ing 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 122

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 0084 button (Y page 123) 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 condition of charge of the starter
battery is sufficient again, the switch-on inter-
lock will be deactivated. To charge the starter
battery, let the engine run. The engine run
time required to reach the necessary condi- tion of charge depends on the outside tem-
perature and on the electrical consumers
switched on. Outside tempera-

Important information You can switch the auxiliary heating on/off
and set the operating duration using the
remote control. You can use up to 4 remote
control units on the vehicle. These must be
synchronized for the receiver in your vehicle
(Y page 126). The remote control has a maximum range of
approximately 600 meters. This range is
reduced by:
R sources of interference
R solid objects between the remote control
and the vehicle
R the remote control being in an unfavorable
position in relation to the vehicle
R transmitting from an enclosed space
