Driving
The coolant temperature is above
248°F (120°C)
The coolant is too hot and is no longer
cooling the engine.
Stop the vehicle as soon as possible
and turn off the engine. Allow engine
and coolant to cool.

Check the coolant level and add cool-
ant if necessary (
page 332).In case of accident
If the vehicle is leaking fuel:

Do not start the engine under any
circumstances.

Notify local fire and/or police authori-
ties.
If the extent of the damage cannot be de-
termined:

205 Controls in detail
Climate control
The climate control is operational whenev-
er the engine is running. You can operate
the climate control system in either the au-
tomatic or manual mode. The system cools
or heats the interior depending on the se-
lected interior temperature and the cur-
rent outside temperature.Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
The air conditioning will not engage (no
cooling) if the A/C mode is deactivated
(
page 211).
Warning!
G
When operating the climate control, the air
that enters the passenger compartment
through the air vents in the footwell can be
very hot or very cold (depending on the set
temperature). This may cause burns or frost-
bite to unprotected skin in the immediate
area of the air vents. Always keep sufficient
distance between unprotected parts of the
body and the footwell air vents. If necessary
change the air flow using the air distribution
controls (
page 204) to direct the air away
from the footwell air vents.
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
iSevere conditions (e.g. strong air pollu-
tion) may require replacement of the fil-
ter before its scheduled interval. A
clogged filter will reduce the air volume
to the interior.
If the vehicle interior is hot, ventilate
the interior before driving off.
Keep the air intake grille in front of the
windshield free of snow and debris.

Deactivating
Press button:.
The indicator lamp on the button goes
out.
Warning!
G
Never operate the windows and tilt/sliding
sunroof* if there is the possibility of anyone
being harmed by the opening or closing pro-
cedure.
In the event that the closing procedure
causes potential danger, the closing of the
side windows can be immediately halted by
pressing or pulling the respective window
switch. The procedure for the tilt/sliding
sunroof can be immediately halted by mov-
ing the switch for the tilt/sliding sunroof in
any direction.
The closing of the side windows and the
tilt/sliding sunroof can be reversed by again
pressing and holding the :button.
iThe air recirculation mode is activated
automatically at high outside tempera-
tures.
After 30 minutes at the latest, outside
air is added.
If you have turned off the air condition-
ing (
page 211) or the outside
temperature is below 41°F (5°C), the
air recirculation mode will not switch
on automatically.
iTo achieve the fastest possible cooling
of the interior, the climate control auto-
matically switches to air recirculation.
The indicator lamp in the button:
is not illuminated when the system au-
tomatically switches to air recircula-
tion.
iPress and hold button: for approx.
two seconds. You can release
button: once the opening proce-
dure has begun. The windows and
tilt/sliding sunroof* continue opening
until they have reached their previous
position.
A window or tilt/sliding sunroof* will
only return to its previous position if it
has not been moved to another posi-
tion using the respective window
switch or tilt/sliding sunroof* switch
after it was closed with button:.
A window or tilt/sliding sunroof* that
was moved will remain in its current po-
sition if button: i s u s e d t o r e - o p e n
the remaining windows or tilt/sliding
sunroof*.

211 Controls in detail
Climate control
At outside temperatures above 79°F
(26°C), the system will not automatically
switch back to outside air. A quantity of
outside air is added after approximately
30 minutes.
Air conditioning
The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.
In addition, the air conditioning dehumidi-
fies the interior air at outside temperatures
above 41°F (5° C) and helps prevent
window fogging.Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the climate
control system. The air in the vehicle will
then no longer be cooled or dehumidified.

Press button2 (
page 204).
The indicator lamp on the button2
goes out.
iThe air recirculation mode is
deactivated automatically

after five minutes if the outside
temperature is below
approximately 41°F (5°C)


after five minutes if the air condi-
tioning and air-drying is turned off


after 30 minutes if the outside
temperature is above
approximately 41°F (5°C)
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.Warning!
G
If you turn off the cooling function, the
interior air is not dried. The windows can fog
up more quickly. Window fogging may im-
pair visibility and endanger you and others.

214 Controls in detailClimate controlDeactivating rear air conditioning
For an improved cooling or heating output
in the front passenger compartment, you
can switch off the rear passenger compart-
ment ventilation.

3-zone automatic climate control*
Maximum cooling MAX COOL
If the air distribution control as well as the
airflow volume control are set toU and
there is a high need for cooling, the display
“MAX COOL” appears in the front and rear
display.
This provides the fastest possible cooling
of the vehicle interior (when windows and
tilt/sliding sunroof* are closed).Defrosting
If the air volume is switched off or the air
recirculation mode is switched on, the
interior is not any longer ventilated and the
windows can get fogged on the inside.Activating

Press button0 (
page 218).
The indicator lamp on button0
comes on.
The climate control switches automatically
to the following functions:


maximum blower and heating power


air flows onto the windshield and the
front side windows (side air vents must
be open)


The climatic compressor is switched on
at outside temperatures above approx-
imately 41°F (5°C) for air-drying
Deactivating

Press button0.
The yellow indicator lamp on the button
goes out. Defrosting is turned off.
Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e.g. before a tunnel trav-
el). This setting cuts off the intake of out-
side air and recirculates the air in the
passenger compartment.
iThese settings should only be selected
for a short time.
When the defrost setting has been se-
lected, only the rear window defroster
can be switched on. No other settings
are possible.
iTo switch off you can press also the
button´ orU.
Warning!
G
Fogged windows impair visibility,
endangering you and others. If the windows
begin to fog on the inside, switching off the
air recirculation mode immediately should
clear interior window fogging. If interior win-
dow fogging persists, make sure the air
conditioning (
page 225) is activated, or
press button0.
