Risk of accident
If you switch off the "Cooling with air dehu-
midification" function, the air inside the vehi-
cle will not be cooled (in warm weather) or
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions and thereby
cause an accident.
Condensation may drip from the underside of
the vehicle when Thermatic is in cooling
mode.

matically
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic air conditioning will achieve
optimal operation if "cooling with air dehu-
midification" is also activated. If necessary,
cooling with air dehumidification can be deac-
tivated.

Risk of injury
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 air
vents. Keep bare skin away from these air
vents. If necessary, direct the airflow to a dif-
ferent 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 air inlet and outlet
grilles in the vehicle interior.
i For virtually draught-free ventilation,
adjust the sliders of the air vents to the
centre position.

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 impair-
ing visibility and endangering yourself and
others. This may prevent you from observing
the traffic conditions, thereby causing an

Risk of injury
Make sure that nobody can become trapped
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
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, press the
g button again. Press the button for stop-
ping, opening or closing the side windows in
the opposite direction as appropriate.

The "residual heat" function is only available
with Thermotronic luxury 3-zone automatic
climate control*.
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.
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.
i It is possible that the "residual heat" func-
tion may be activated automatically an hour
after the key is removed. The vehicle is then
ventilated for 30 minutes to dry the air con-
ditioning system.

Notes on the auxiliary heating/ventila-
tion system G
Risk of poisoning
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
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 vehi-
cle is being refuelled. You must therefore
switch off the auxiliary heating at filling sta-
tions.
i Switch the auxiliary heating on regularly
once a month for about ten minutes.
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 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 Air conditioning

You cannot use the auxiliary ventilation to

lower than the outside 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 135).
Switching the auxiliary heating/venti-
lation on/off using the button on the

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 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.

when the batteries in the remote control
are low. Replace the remote control bat-
teries (Y page 304). 182

General notes
G
Risk of injury
Make sure that nobody can become trapped
when closing the sliding sunroof. If there is a
risk of entrapment, release the switch and
push it briefly in any direction to stop the slid-
ing sunroof. G
Risk of injury
Children could injure themselves if they oper-
ate the sliding sunroof.
Never leave children unsupervised in the vehi-
cle. Always take the key with you when leaving
the vehicle, even if you are only leaving it for
a short time. G
Risk of injury
The glass in the panorama 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 panorama sliding sunroof
if it is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding sunroof. The seals could otherwise
be damaged.
i When the sliding sunroof is open, apart
from the normal airflow noises resonance
noises may also occur. They are caused by
minor pressure fluctuations in the vehicle
interior. Change the position of the sliding
sunroof or open a side window slightly to
reduce or eliminate these noises.
