WARNING
Make sure that nobody can become trapped
between the side window and the door frame
as the side windows are opened and closed.
Make sure that all objects and body parts are
clear of the side windows when they are being
opened or closed. You or the objects could be
drawn in or become trapped between the side
window and the door frame as the window
moves. If there is a risk of entrapment, oper-
ate the Wswitch to move the side window
in the opposite direction.
Make sure that nobody can become trapped
as the panorama sliding sunroof is opened
and closed. If there is a risk of entrapment,
operate the 3switch to move the pano-
rama sliding sunroof in the opposite direction.
X Convenience closing feature: press and
hold the gbutton until the side win-
dows and the panorama sliding sunroof are
closed.
The indicator lamp in the gbutton lights

i If you open the side windows or the pan-
orama sliding sunroof manually after clos-
ing with the convenience closing feature,
they will remain in this position when
opened using the convenience opening fea-
ture. Activating/deactivating the residual
heat function
The "Residual heat" function is only available
with THERMOTRONIC automatic climate con-
trol.
It is possible to make use of the residual heat
of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the temperature that has
been set for the vehicle interior.
i The blower will run at a low speed regard-
less of the airflow setting.
i If you activate the residual heat function
at high temperatures, only the ventilation
will be activated. The blower runs at
medium speed.
X Turn the key to position 0in the ignition
lock or remove it.
X To activate: press theÌbutton.
The indicator lamp in the Ìbutton lights
up.
X To deactivate: press theÌbutton.
The indicator lamp in the Ìbutton goes
out.
i Residual heat is deactivated automati-
cally:
R after approximately 30 minutes
R when the ignition is switched on
R if the battery voltage drops
R when the auxiliary heating is activated 136

Auxiliary heating
Important safety notes G
WARNING
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. a garage. G
WARNING
When operating the auxiliary heating parts of
the vehicle can get very hot. Make sure that
the exhaust system does not under any cir-
cumstances come into contact with easily
ignitable material such as dry grass or fuels.
The material could otherwise ignite and set
the vehicle alight. Choose your parking spot
accordingly.
Operating the auxiliary heating is thus pro-
hibited at filling stations or when your vehicle
is being refuelled. You must therefore switch
off the auxiliary heating at filling stations.
! Operating the auxiliary heating/ventila-
tion draws on the vehicle battery. After you
have heated or ventilated the vehicle a
maximum of two times, drive for a longer
distance.
i Switch the auxiliary heating on regularly
once a month for about ten minutes.
The auxiliary heating heats the air in the
passenger compartment to the selected tem-
perature. It does not use the heat of the run-
ning engine to do this. The auxiliary heating
is operated directly using the vehicle's fuel.
For this reason, the tank content must be at
least at reserve fuel level to ensure that the
auxiliary heating functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux-
iliary heating could switch from ventilation
mode to heating mode or from heating mode
to ventilation mode. The auxiliary heating switches off automati-
cally after 50 minutes. This time limit can be
altered. To do this, visit a qualified specialist
workshop.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature.
Before switching on
X
Turn the key to position 2in the ignition
lock.
X Set the temperature.
The auxiliary heating/ventilation can be acti-
vated even when climate control is set to
manual. Optimum comfort can be attained
when the system is set to automatic mode.
Set the temperature to 22 †.
The auxiliary heating/ventilation can be acti-
vated or deactivated using the remote control
or the button on the centre console.
The on-board computer can be used to spec-
ify up to three departure times, one of which
may be preselected (Y page 242).

lation on/off using the centre console

Switching the auxiliary heating/venti-
lation on/off using the remote control Your vehicle comes with one remote control.
You may use two additional remote controls
for your vehicle. For more information, please
contact a qualified specialist workshop.
The remote control has a maximum range of
approximately 300 metres. This range is
reduced by:
R
sources of radio interference
R solid objects between the remote control
and the vehicle
R the remote control being in an unfavoura-
ble position in relation to the vehicle
R transmitting from an enclosed space
i The optimum range can be achieved if you
hold the remote control vertically, pointing
upwards when you press one of the but-
tons.

Important safety notes
G
WARNING
Very hot or very cold air can flow from the air
vents. This could cause burns or frostbite to
bare skin in the immediate vicinity of the
vents. Keep bare skin away from these air
outlets. If necessary, direct the airflow away
to a different area of the vehicle interior. 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 between the windscreen
and the bonnet free of blockages, such as
ice, snow or leaves.
R never cover the vents or ventilation grilles
in the vehicle interior.
i For virtually draught-free ventilation,
adjust the sliders of the air vents to the
centre position. Adjusting the air vents
