Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Ractivate the "Windshield defrosting" function
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improving the interior
climate.
The cooling with air dehumidification function is
only available when the engine is running. Opti-
mum climate control is only achieved with the
side windows closed.
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 76). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
iThe integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. A clogged filter reduces the
amount of air supplied to the vehicle interior.
Depending on the operating conditions and
environmental influences, the interval for
replacing the filter may be shorter than speci-
fied.
iIt is possible that the blower may be activa-
ted automatically 60 minutes after the engine
has been switched off depending on various
factors, e.g. the outside temperature. The
vehicle is then ventilated for 30 minutes to dry
the climate control system.

Optimum use of 3-zone automatic cli-

Dual-zone automatic climate control
The following contains instructions and recom-
mendations to enable you to get the most out of
your dual-zone automatic climate control:
RActivate climate control using the Ã
rocker switch. The indicator lamp above the
à rocker switch lights up. The "Cooling
with air dehumidification" function is not acti-
vated automatically in automatic mode. If
necessary, activate this function
(
Ypage 99).
RSet the temperature to 72 ‡ (22 †).
ROnly use the "Windshield defrosting" function
briefly until the windshield is clear again.
ROnly use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in
a tunnel. The windows could otherwise fog up, since no fresh air is drawn into the vehicle in
air-recirculation mode.
ECO start/stop function
During automatic engine switch-off, the climate
control system only operates at a reduced capa-
city. If you require the full climate control output,
you can switch off the ECO start/stop function
by pressing the ECO button (
Ypage 109).
Operating the climate control sys-
tems
Setting climate control
General notes
When the climate control is switched off, the air
supply and air circulation are also switched off. The windows could fog up. Therefore, switch off
climate control only briefly
Switch on climate control primarily using the
Ã
rocker switch (
Ypage 100).
Activating/deactivating
XSelect key position 2with the Start/Stop
button (Ypage 106).
XTo switch on: set the airflow to level 1or
higher using the Hrocker switch.
XTo switch off: set the airflow to level 0using
the H rocker switch.
Switching cooling with air dehumidi-
fication on/off
General notes
If you deactivate the "Cooling with air-dehumid-
ification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also
not be dehumidified. The windows can fog up
more quickly. Therefore, deactivate the cooling
with air-dehumidification function only briefly.
The "Cooling with air dehumidification" function is only available when the engine is running. The
air inside the vehicle is cooled and dehumidified
according to the temperature selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc-
tion.
Activating/deactivating
XPress the ¿rocker switch up or down.
The indicator lamp above the ¿rocker
switch lights up or goes out.

function.
XVisit a qualified specialist workshop.
Setting climate control to automatic
General notes
In automatic mode, the set temperature is main-
tained automatically at a constant level. The
system automatically regulates the temperature
of the dispensed air, the airflow and the air dis-
tribution.
During automatic controlling, the "Cooling with
air dehumidification" function is activated.
Automatic control
XSelect key position 2with the Start/Stop
button (Ypage 106).
XTo activate: press rocker switch Ãup or

or
XPress the upper or lower section of the _
rocker switch.
The indicator lamp above the Ãrocker
switch goes out.
In automatic mode, if you adjust the airflow or
air distribution manually, the indicator lamp
above the Ãrocker switch goes out. The
function which has not been changed manually,
however, continues to be controlled automati-
cally. When the manually set function switches
back to automatic mode, the indicator lamp
above the Ãrocker switch lights up again.
Setting the temperature
Different temperatures can be set for the driv-
er's and front-passenger sides.
XSelect key position 2with the Start/Stop
button (Ypage 106).

Rear window defroster
General notes
The rear window defroster has a high current
draw. You should therefore switch it off as soon
as the rear window is clear. Otherwise, the rear
window defroster switches off automatically
after several minutes.
If the battery voltage is too low, the rear window defroster may switch off.

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.

!Avoid making long journeys with too little coolant in the engine
cooling system. The engine will otherwise be damaged.
XAdd coolant, observing the warning notes before doing so
(Ypage 236).
XIf coolant needs to be added more often than usual, have the engine coolant system checked at a qualified specialist workshop.
?The fan motor is malfunctioning.
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.

Coolant Too HotStop Vehicle TurnEngine 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 122).
XWait 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 gauge.
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 †).
