Heating and air-conditioning system
Air-recirculation mode switches off automati-
cally after about 10 to 30 minutes, depending on
the outside temperature.
XSwitch on climate control (Ypage 102).
XTo activate/deactivate:press theebut-

If the indicator lamp in the ebutton lights
up, air-recirculation mode is activated.
Rear-compartment heating and rear-
compartment air-conditioning system
On vehicles with rear-compartment heating and
a rear-compartment air-conditioning system,
you can activate or deactivate air-recirculation
mode for the rear-compartment climate control.
XSwitch on climate control (Ypage 102).
XTo activate: set the temperature control of
rear-compartment heating =(Ypage 101) or
rear-compartment air conditioning system ;
(
Ypage 102) to the center position.
Only one of the two climate control systems in
the rear compartment is activated and is in
air-recirculation mode.
XTo deactivate: turn the temperature control

clockwise. Only change the temperature in
small increments.
Adjusting the air vents
Important safety notes
GWARNING
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-condi-
tioning system, you can also adjust the air vents
in the roof duct.
iFor 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:
Rkeep the air inlet grille on the hood free of
blockages, such as ice, snow or leaves.
Rnever cover the vents or the ventilation grilles
in the vehicle interior.

Adjusting air vents for the passenger
compartment
Air vents (example: right-hand side of the vehicle)
You can use the air vents to ventilate the vehicle
interior on the left and right, in the rear and the
headroom.
XTo open: for the right-hand side of the vehi-
cle, turn thumbwheel ;to the left or for the
left-hand side of the vehicle, thumbwheel :

XTo close: for the right-hand side of the vehi-
cle, turn thumbwheel ;to the right or for the
left-hand side of the vehicle, thumbwheel :

Adjusting the air vents in the roof duct
!
Always leave at least one air vent open.
If the rear-compartment air conditioning is
switched on and all the air vents are closed,
the air-conditioning system may be damaged.
On vehicles with rear-compartment air condi-
tioning, adjustable air vents are integrated into
the roof duct.
XTo adjust the airflow: open or close the air
flap in air vents :as needed.
XTo adjust the air distribution: turn air
vent :to the desired position.
Operating the auxiliary heating sys-
tem
Important safety notes
GDANGER
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 anadequate supply of fresh air, open a window
on the side of the vehicle that is not facing into
the wind.
Operating the auxiliary heating system107

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 109) or
with the remote control (Ypage 110).
Rauxiliary warm-air heater is done via the timer
above the overhead control panel
(
Ypage 114).
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 112) 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.

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 a maximum of two times
without the engine running if the outside tem-
perature is Ò5 ‡ (Ò20 †). If you attempt to do it
again, the indicator lamps in the y
(
Ypage 109) button flash alternately for about
two minutes indicating restarting lock. 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.

Operation with the remote control
Important information
You can switch the auxiliary heating on/off and
set the operating duration using the remote con-
trol. You can use up to 4 remote control units on
the vehicle. These must be synchronized for the
receiver in your vehicle (
Ypage 111).
The remote control has a maximum range of
approximately 600 meters. This range is
reduced by:
Rsources of interference
Rsolid objects between the remote control and
the vehicle
Rthe remote control being in an unfavorable
position in relation to the vehicle
Rtransmitting from an enclosed space

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.
