Activating/deactivating cooling with air dehumidification
Gene ral notes
If you deactivat eth e"Cooling wit hair-dehumidification "function ,th eair inside th evehicl ewill no t
be cooled .The air inside th evehicl ewill also no tbe dehumidified. The windows can fog up mor e
quickly. Therefore ,only deactivat eth e"Cooling wit hair-dehumidification "function briefly.
The "Cooling wit hair dehumidification "function is only available when th eengin eis running.
The air inside th evehicl eis cooled and dehumidified according to th etemperature selected.
Condensation may dri pfrom th eunderside of th evehicl ewhen it is in coolin gmode. This is normal
and no t asign that there is amalfunction .

!If th ecoolin gwit hair dehumidification does no tswitch on ,it is possibl ethat th eclimat econtrol
system has lost coolant.

Setting climate control to automatic
GWARNING
If you switch off the cooling function, the vehi- cle will not be cooled when weather condi-
tions are warm. The windows can fog up more
quickly. Window fogging may impair visibility
and endanger you and others.
In automatic mode, the set temperature is main-
tained at a constant level. The system automat-
ically regulates the temperature of the dis-
pensed air, the airflow and the air distribution.
Automatic mode will achieve optimal operation
if cooling with air dehumidification is also acti-
vated. If desired, cooling with air dehumidifica-
tion can be deactivated.

attempt to activate it and then goes out again.
iThe windshield defroster has a high current
draw. You should therefore switch it off as
soon as the windshield is clear. Otherwise,
the windshield heating switches itself off
automatically after 10 minutes.
iWhen the windshield heating is switched on
for the fourth time in a row, it switches itself
off automatically after 5 minutes.

minutes.
iIf the battery voltage is too low, the rear
window defroster may switch off.
Problems with the rear window
defroster
If the indicator lamp in the ªrear window
defroster button flashes, the on-board voltage is
too low. The rear window defroster has deacti-
vated prematurely or cannot be activated.
XSwitch off any consumers that are not
required, e.g. reading lamps or interior light-
ing.
When the battery is sufficiently charged, the
rear window defroster is activated again auto- matically.
Activating/deactivating air-recircula-
tion mode
If you switch on air-recirculation mode, the win-
dows can fog up more quickly, in particular at
low temperatures. Only use air-recirculation
mode briefly to prevent the windows from fog-
ging up.

Convenience opening or closing using
the air-recirculation button
GWARNING
When the convenience closing feature is oper- ating, parts of the body could become trapped
in the closing area of the side window and the
sliding sunroof. There is a risk of injury.
Observe the complete closing procedure
when the convenience closing feature is oper-
ating. Make sure that no body parts are in
close proximity during the closing procedure.
GWARNING
During convenience opening parts of the body could be drawn in or become trapped
between the side window and window frame.
There is a risk of injury.
Make sure that nobody touches the side win-
dow during the opening procedure. If some-
one becomes trapped, immediately press
the W switch in the door to stop the move-
ment of the side windows. To continue closing
the side window, pull on the Wswitch.
XConvenience closing feature: press and
hold the grocker switch up or down until
the side windows and the sliding sunroof start
to close automatically.

switch lights up. Air-recirculation mode is
activated.
If you manually open the side windows or the
sliding sunroof after closing with the conve- nience closing feature, they will remain in this
position when opened.
If parts of the body are in the closing area during
convenience closing, proceed as follows:
XPress the Wbutton to stop the side win-
dows.
The side window stops.
XTo then open the side windows, press the
W button again.

Activating/deactivating the residual
heat function
The "residual heat" function is only available in
Canada.
It is possible to make use of the residual heat of
the engine to continue heating the stationary
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 tem-
perature that has been set.
iThe blower will run at a low speed regardless
of the airflow setting.
iIf you activate the residual heat function at
high temperatures, only the ventilation will be
activated.
XTurn the SmartKey to position 0(Ypage 112)
in the ignition lock or remove it.
XTo activate: press theÁbutton.

Setting the air vents
Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
General notes
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
Rkeep the air intake grill on the hood free of
blockages, such as ice, snow or leaves.
Rnever cover the air vents or air intake grilles in
the vehicle interior.
iFor virtually draft-free ventilation, adjust the
sliders of the air vents to the center position.
iIf the automatic climate control constantly
differs from the set temperature or if unde-
sired drafts are noticeable, proceed as fol-
lows:
XOpen the side air vents
XOpen the center air vents
XOpen the rear air vents
XSet the temperature to 72 ‡ (22 †).
The automatic climate control adjusts to the set temperature.
