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.
The indicator lamp above the grocker
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.
XPress the 3switch to stop the sliding sun-
roof.
The sliding sunroof stops.
XTo then open the sliding sunroof, pull back on
the 3 switch.
XConvenience opening feature: press and
hold the grocker switch up or down until
the side windows and the sliding sunroof start
to open automatically.
The indicator lamp above the grocker
switch goes out. Air-recirculation mode is
deactivated.
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.
The indicator lamp in the Ábutton lights
up.

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.

The coolant temperature
gage shows a value
above 248 ‡ (120 †). A
display message may
also appear in the multi-
function display and a
warning tone may sound.The coolant level is too low. The coolant is too hot and the engine is no
longer being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant to
cool down.
XCheck the coolant level (Ypage 238). Observe the warning notes
as you do so and add coolant if necessary.
If the coolant level is correct, the radiator fan may be faulty. The cool-
ant is too hot and the engine is no longer being cooled sufficiently.
XAt coolant temperatures below 248 ‡(120 †), drive to the nearest
qualified specialist workshop.
XAvoid heavy loads on the engine as you do so, e.g. driving in moun-
tainous terrain and stop-and-go traffic.

Automatic transmission
Important safety notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
GWARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.
After switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parking
brake.

The coolant level is too low.
XAdd coolant, observing the warning notes before doing so
(Ypage 238).
XHave the coolant system checked at a qualified specialist workshop
if the coolant needs topping up more often than usual.
?The fan motor is faulty.
XAt coolant temperatures below 248 ‡(120 †), drive to the nearest
qualified specialist workshop.
XAvoid heavy loads on the engine as you do so, e.g. driving in moun-

Coolant Too HotStopVehicleSwitchEngine Off
The coolant is too hot.
A warning tone also sounds.
GWARNING
Do not drive when your engine is overheated. This can cause some
fluids which may have leaked into the engine compartment to catch
fire.
Steam from the overheated engine can also cause serious burns which
can occur just by opening the hood.
There is a risk of injury.
XPull over and stop the vehicle safely and switch off the engine, pay- ing attention to road and traffic conditions.
XSecure the vehicle against rolling away (Ypage 130).
XLeave the vehicle and keep a safe distance from the vehicle until the
engine has cooled down.
XMake sure that the air supply to the engine radiator is not blocked,
e.g. by snow, slush or ice.
XDo not start the engine again until the display message goes out and
the coolant temperature is below 248 ‡ (120 †). Otherwise, the
engine could be damaged.
XPay attention to the coolant temperature display.
XIf the temperature increases again, visit a qualified specialist work-
shop immediately.
Under normal operating conditions and with the specified coolant
level, the coolant temperature may rise to 248 ‡ (120 †).
