G
Risk of injury
Very hot or very cold air can flow from the
air vents. This could cause burns or frost-
bite 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 vehi-
cle interior.
Please observe the following notes to ensure
that the air can flow freely through the air
vents:
R keep the air inlet between the windscreen
and the bonnet free of deposits, such as ice
and snow, to guarantee the supply of fresh
air into the vehicle interior.
R never cover the vents or air inlet and outlet
grilles in the vehicle interior.
i Position the sliders for the centre air
vents in the central position to provide vir-
tually draught-free ventilation. Cont

Risk of accident

ting off. Impaired visibility could otherwise
endanger you and others.
i At very low temperatures, the rear win-
dow heating is only switched on once the
vehicle interior has warmed up.
i The rear window heating has a high cur-
rent draw. You should therefore switch it
off as soon as the window is clear, as it only
switches off automatically after several
minutes.
i If the battery voltage is too low, the rear
window heating may switch off.

unpleasant odours are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated. G
Risk of accident
Only switch over to air-recirculation mode
briefly at low outside temperatures. Other-
wise, the windows could mist up, thus
impairing visibility and endangering your-
self and others. This may prevent you from
observing the traffic conditions, thereby
causing an accident.

Risk of injury
Make sure that nobody can become trap-
ped between the side window and the door
frame as the side windows are opened and
closed. Do not place objects or lean against
the side window when it is 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,
press the :button again. Press the but-
ton for stopping, opening or closing the side
window in the opposite direction as appro-
priate.

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 set interior temperature.
i The blower will run at a low speed regard-
less of the airflow setting.

at high temperatures, only the ventilation
will be activated. The blower runs at
medium speed.

Risk of poisoning
Exhaust fumes are produced when the aux-
iliary 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 system, e.g. a garage. G
Risk of fire
When operating the auxiliary heating, parts
of the vehicle may become very hot, and
highly inflammable material such as fuels
could be ignited. Operating the auxiliary
heating is thus prohibited at filling stations
or when your vehicle is being refuelled. You
must therefore switch off the auxiliary heat-
ing at filling stations.
The auxiliary heating heats the air in the vehi-
cle interior to the set temperature without
using the heat of the running engine. The aux-
iliary heating is operated using fuel directly from the vehicle's fuel tank. 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.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature.
Before activating
X
Turn the key to position 2in the ignition
lock.
X Set the temperature.
The auxiliary heating/ventilation can be acti-
vated even when the air conditioning is being
controlled manually. Optimum comfort can
be attained when the system is set to auto-
matic 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 133).

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 further information, con-
sult a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre. The remote control has a maximum range of
approximately 300 metres. This range may be
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.
i A battery symbol appears in the display
when the batteries in the remote control
are low. Replace the remote control bat-
teries (Y page 312).

Risk of injury
Children could injure themselves if they
operate the sliding/tilting sunroof.
Never leave children unsupervised in the
vehicle. Always take the KEYLESS–GO
key* with you when leaving the vehicle,
even if you are only leaving it for a short
time. G
Risk of injury
Make sure that nobody can become trap-
ped when you are opening and closing the
sliding/tilting sunroof. If there is a risk of
entrapment, release the switch and push it
briefly in any direction to stop the sliding/
tilting sunroof. G
Risk of injury
The glass in the sliding/tilting sunroof
could break in an accident. If you are not
wearing a seat belt, there is a risk that you
could be thrown through the opening in the
event of the vehicle overturning. Therefore,
always wear a seat belt to reduce the risk
of injuries. !
Only open the sliding/tilting sunroof if it
is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding/tilting sunroof. The seals could oth-
erwise be damaged.
i Resonance noises can occur in addition
to the usual airflow noises when the slid-
ing/tilting sunroof is open. They are caused
by minor pressure fluctuations in the vehi-
cle interior.
Change the position of the sliding/tilting
sunroof or open a side window slightly to
reduce or eliminate these noises.
i It is also possible to open and close the
sliding/tilting sunroof from the outside
using the "Summer opening" (Y page 101)
and "Convenience closing" (Y page 102)
features respectively.
When PRE-SAFE ®
* has been activated, the
sliding/tilting sunroof closes automatically in
the event of danger, leaving a small gap open. Controls
