Air conditioning
129Activating/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 To activate: briefly 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
the , button is not lit.
Outside air is added after about 30
minutes. X
To deactivate: press the,button.
The indicator lamp in the ,button goes
out.
i Air-recirculation mode switches off auto-
matically:
R after approximately five minutes at out-
side temperatures below approximately
5 †
R after approximately five minutes if cool-
ing with air dehumidification is deactiva-
ted
R after approximately 30 minutes at out-
side temperatures above approximately
5 † Switching the residual heat on/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 coolant temperature and
on the interior 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.
X Make sure that the key is in position 1or
0 in the ignition lock or that it has been
removed.
X To switch on: press the9button.
The indicator lamp in the 9button lights
up.
X To deactivate: press the9button.
The indicator lamp in the 9button goes
out.
i The auxiliary heating/ventilation is auto-
matically deactivated after about 30
minutes, or when:
R the ignition is switched on
R the battery voltage drops
R when the coolant temperature is too low Cont

Air conditioning
130 Auxiliary heating/ventilation*
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 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
It is preferable to set the air conditioning to
U.
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 obtained by activating automatic mode
and setting the temperature to 22 †.
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
page 108).
For direct access to the Heatersubmenu in
the on-board computer: X
Make sure that the key is in position 1
or 2in the ignition lock.
X Press the auxiliary heating/ventilation but-
ton for about three seconds.
The auxiliary heating switches off automati-
cally after 50 minutes.
i This time limit can be altered. To do this,
visit a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.

Deactivating the auxiliary heating/venti-
lation
X Press and hold button 1for more than two

button goes out. Remote control
Your vehicle comes with one remote control.
You may use one additional remote control
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 More information about the auxiliary
heating can be found in the "Practical
advice" section (Y page 228). Auxiliary heating remote control

Risk of injury
Children could injure themselves if they
operate the sliding/tilting sunroof.
Never leave children unsupervised in the
vehicle. 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
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
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 over-
turning. 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" and "Conve-
nience closing" features respectively. Controls
