Overview of air-conditioning systems
The vehicle is equipped with one of the following air-conditioning systems: 2-zone Thermatic
4-zone Thermotronic*
Rear-compartment air conditioning*
242-zone Thermatic is an automatic air-condi-
tioning system combining an automatic heat-
ing and ventilation system with a cooling
system. 4-zone Thermotronic is a luxury automatic
air-conditioning system combining an auto-
matic heating and ventilation system with a
cooling system. You can control the air con-
ditioning separately for each zone in the vehi-
cle. The rear-compartment air conditioning
allows a separate temperature setting for the
rear compartment.

Risk of accident
Clear all windows of ice or snow before set-
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 approxi-
mately six to twenty minutes.
i If the battery voltage is too low, the rear
window heating may switch off.
i Saloon: there are aerial wires in the upper
area of the rear window; this area is there-
fore not heated.
X Make sure that the key is in position 2in

X Press the ¯button.
The indicator lamp in the ¯button lights
up or goes out. Activating/deactivating air-recircula-
tion mode
You can deactivate the flow of fresh air if
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.
X Make sure that the key is in position 2in
the ignition lock.
X To activate: press the,button.
The indicator lamp in the ,button
comes on.
i Air-recirculation mode is activated auto-
matically at high outside temperatures.
When air-recirculation mode is activated
automatically, the indicator lamp in

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. If necessary,
press the switch that stops, opens or closes
the side window in the opposite direction.
Make sure that nobody can become trap-
ped when you open or close the sliding/
tilting sunroof*/panorama sliding sun-
roof*. If there is a risk of entrapment, press
the , button again. If necessary, press
the switch that stops, opens or closes the
sliding/tilting sunroof*/panorama sliding
sunroof* in the opposite direction.
X Convenience closing: press and hold
the , button until the side windows and
the sliding/tilting sunroof*/panorama
sliding sunroof* have closed.

ted.
X Convenience opening: press and hold
the , button until the side windows and
the sliding/tilting sunroof*/panorama

position.
The indicator lamp in the ,button goes
out. Air-recirculation mode is deactivated. i
If you open the side windows or the slid-
ing/tilting sunroof* or panorama sliding
sunroof* manually after closing using the
convenience closing feature, it will remain
in this position when opened using the con-
venience opening feature. Switching the residual heat on and off
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.
i If you activate the "residual heat" function
at high temperatures, only the ventilation
will be activated. The blower runs at
medium speed.
X Make sure that the key is in position 0in
the ignition lock or that it has been
removed.

G
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 a temperature between 20 †
and 24 †, without depending on heat emitted
by the running engine. The auxiliary heating
is operated using fuel directly from the vehi-
cle's fuel tank. For this reason, the tank con-
tent 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
Make sure that the key is in position 2in
the ignition lock.
X Set the temperature to a value between
20 † and 24 †.
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 desired temperature
within this range. If a higher temperature is
set, the vehicle is heated to 24 †. If a lower
temperature is set, the vehicle is heated to
20 †.
Activating/deactivating the auxiliary
heating/ventilation
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

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 311). Controls

Risk of injury
Never leave children unsupervised in the
vehicle. They could operate the sliding/tilt-
ing sunroof and injure themselves. Always
take the key with you when leaving the
vehicle, even if you only leave 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 danger threatens,
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. Controls
