Air conditioning
CAUTION
● If you suspect that the air conditioner system is damaged, switch over to
ECON mode to prevent further damage and have the system checked by a
specialised workshop.
● Repairs to the air conditioner require specialist knowledge and special
tools. For this reason, please contact a specialised workshop if the system
is not working properly.
Note
● Keep the air intake slots in front of the windscreen clear of snow, ice and
leaves to ensure unimpaired heating and cooling and to prevent the win-
dows misting over.
● The air from the outlets flows through the passenger compartment and
out through the slots below the rear window. Therefore, do not cover these
slots with items of clothing or other objects.
● The air conditioner operates most effectively with the windows and the
sliding/tilting sunroof* closed. However, if the vehicle has heated up after
standing in the sun for some time, the air inside can be cooled more quickly
by opening the windows briefly. 

The ,  and  buttons (which regulate air distribution) can either be
selected individually or in combination. 
Automatic mode AUTO
Standard setting for all seasons.
Switching on automatic mode
– It is possible to select interior temperatures from +18°C (64°F)
to +29°C (86°F).
– Press the AUTO
⇒ 
Fig. 139 button.
The automatic mode maintains a constant temperature inside the vehicle
and dehumidifies the air. Air temperature, air delivery and air distribution
are regulated automatically to reach the desired interior temperature as
quickly as possible, and then to maintain this temperature. The system au-
tomatically compensates for any variations in the outside temperature and
for the effect of direct sunlight.
The automatic temperature regulation only operates at temperature settings
between +18°C and +29°C. If a temperature below +18°C is selected, LO ap-
pears on the display. If a temperature is selected which is higher than +29°C, the display will show
HI. In the maximum and minimum settings, the
climate control operates continuously with maximum cooling or heating
output and the temperature is not regulated automatically. The temperature
is not regulated.
Note
By keeping the AUTO button on the driver side pressed for several seconds,
the temperature of the passenger side can be set to the temperature of the
driver side or vice versa. The display indicates the new temperature value. 
Selecting the temperature -
+
Separate temperatures can be selected for the driver and
front passenger sides.
– Press the -
or + buttons below the displays
⇒ Fig. 139 until
the desired temperature is selected for the driver side or front
passenger side.
The currently selected temperature setting is shown in the display above
the buttons.
By keeping the AUTO
button on the driver side pressed for several seconds,
the temperature of the passenger side can be set to the temperature of the
driver side or vice versa. The display indicates the new temperature value.
The previous temperature setting can be restored by resetting the display
on the driver or passenger side as required. 

Defrosting 
The windscreen and side windows are defrosted or demisted
as quickly as possible.
– To enable this mode, press the 
⇒ 
Fig. 139 button.
– To switch off, press the 
button again, or select the AUTO but-
ton.
The temperature is regulated automatically. The air output is increased to
maximum and most of the air comes out of outlets 1 and 2 ⇒ page 169.
The air recirculation and ECON modes are switched off when the 
button
is pressed. 
Air recirculation: manual activation 
The air recirculation setting prevents fumes etc. from enter-
ing the interior.
Activating air recirculation mode
– Press button 
⇒ Fig. 139 ⇒ .
Deactivating air recirculation mode
– Press the 
button again or
– Press the AUTO
button or
– Press button 
.
In this setting, the air in the vehicle is constantly recirculated. We recom-
mend using the air recirculation mode in the following circumstances: ●
When driving through a tunnel or in traffic congestions, to prevent ex-
haust gas entering the interior of the vehicle.
WARNING
Do not drive for too long with the air recirculation mode enabled because,
if the compressor is disconnected, the windscreen may mist up because
no fresh air is entering the interior of the vehicle, with the subsequent
risk of accidents.

ECON Mode (economy) ECON
ECON mode helps save fuel.
– To activate, press the ECON
button ⇒ Fig. 139.
– To deactivate, press the ECON
button again or select the AUTObutton.
Air cooling is disconnected in ECON mode. The heating and the blower are
adjusted automatically. “ECON” stands for “Economy”. Disconnecting air
cooling (compressor) reduces fuel consumption.
Please note that the interior temperature must not be lower than the outside
temperature in ECON mode. The blower does not cool or dehumidify the air
in the interior. The windows could therefore mist up.
In diesel vehicles, the auxiliary heater is switched off in ECON mode to save
fuel. 

Air conditioning
Note
If the diode on the ECON button continues to light up when the ECON mode
has been switched off (i.e. the air conditioner has been switched on) this is
due to a defect in one of the air conditioner components. If a malfunction
should occur, please contact a specialised workshop. 
Air recirculation: automatic activation* 
If the outside air is polluted by diesel and petrol emissions,
an air quality sensor in the vehicle will automatically switch
on the air recirculation.

.
The automatic air recirculation mode should normally be left switched on at
all times.
The system is ready to operate approx. 30 seconds after the engine ignition
key has been turned. During this initial period, fresh air is fed into the vehi-
cle.
If the air purity sensor in the air conditioner detects a certain concentration
of fumes in the outside air, the control unit will either pass the incoming air
through the pollution filter or automatically switch on the air recirculation. If
there is a high concentration of pollution in the outside air, the air condi-
tioner automatically switches to air recirculation and the supply of air from
the outside is cut off. As soon as the level of pollution decreases, air is fed
into the vehicle from the outside again.
The automatic air recirculation operates for a maximum period of 12 mi-
nutes. If the windows mist up when the automatic air recirculation is on,
press the 
button immediately.
The automatic air recirculation switches itself off under certain circumstan-
ces (for instance if 
or  is selected). In “ECON” and at temperatures
lower than approx. 8°C below zero, the automatic air recirculation mode is
limited to 12 seconds. 

Air directed to windows 
This setting directs all the air to outlets 1 and 2. Unlike in setting , the
volume of air delivery remains the same.
Air to the driver/front passenger 
All the air comes from outlets 3 and 4 in the dash panel and from the rear of
the centre console.
Air to the footwells 
Most of the air emerges from outlets 5 and the outlets under the front seats.
Some of the air will also be issued from outlets 3 and 4.
Note
In all of the above air distribution settings, a small amount of air will still
come from the other outlets. 
Economical use of the air conditioner
Economical use of the air conditioner will help save fuel.
Engine power is reduced and fuel consumption increases when the
air conditioner is in cooling mode. To ensure that the system is on-
ly switched on when it is really necessary, please note the follow-
ing points:
– Select ECON mode if you wish to save fuel.
– Select ECON mode if you decide to open the windows or sun-
roof* while driving.
– If the vehicle has heated up after standing in the sun, open the
windows and doors for a short time to cool the vehicle.
For the sake of the environment
By saving fuel you also reduce the amount of pollutants emitted from your
vehicle. 
Key settings
When the ignition is switched on, the air conditioner set-
tings assigned to the key are selected automatically.
The air conditioner settings selected are automatically stored and assigned
to the key in use. When the vehicle is started, the air conditioner automati-
cally selects the settings assigned to the key. Hence, every driver automati-
cally obtains his/her preferred settings without having to select them man-
ually.
Note
Should another driver use the key and enter other settings, the previous
settings will be deleted. 
Solar-powered blower/sunroof*
If the vehicle is parked in sufficiently strong sunlight, the
blower will operate in solar-powered mode when the igni-
tion is switched off.
After the ignition is switched off, the blower is supplied with electrical pow-
er from the sunroof. Please ensure that outlets 3 and 4 are open ⇒ Fig. 141
to ensure the best possible ventilation.
The blower only works when the sunroof is closed or tilted open at the rear. 

176Driving
WARNING
● Never switch the engine off until the vehicle is stationary.
● The brake servo and the power steering system work only when the
engine is running. You need more strength to steer and brake the vehicle
when the engine is switched off. Given that you will be unable to steer
and brake as usual, this could lead to a risk of accidents and injuries.
CAUTION
If the engine has been running under high load for a long time, there is a
risk of heat building up in the engine compartment after the engine has
been switched off; this could cause engine damage. Therefore, you should
let the engine idle for approximately 2 minutes before you switch it off.
Note
After the engine is switched off the radiator fan may run on for up to 10 mi-
nutes, even if the ignition is switched off. It may also start running again af-
ter some time if the coolant temperature rises due to a build-up of heat un-
der the bonnet, or if the engine is already warm and the engine compart-
ment is heated up further by direct sunlight. 
