[ i J Tips
If the climate control system is operating in cooling mode, air flows
primarily from the outlets in the center console and in the door
pillars . To achieve adequate cooling, you should never close the
outlets completely. •
Using climate controls economically
Using the climate controls prudently can help save fuel.
When you use the air conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should
use the air conditione r only when necessary. Also please
n ote the following points:
- If you want to save fuel, activate ECON.
If you are going to drive with the windows open, use
ECON.
W For the sake of the environment
By reducing the amount of fuel you use, you also reduce the amount
of pollutants emitted into the air.•
Applie s to v ehicl es: with so lar slidi ng /tilt ing sunr oof
Solar blower fan /solar roof
With sufficient sunlight, the blower fan continues to
operate with solar energy to bring in fresh air after the
ignition has been switched off.
T he fan motor is operated by solar energy through the solar roof
after the ignition is turned off. Please make certain that vents ©
and © are open to achieve optimal ventilation=>
page 122, fig. 137.
Con tro ls and eq uip­
ment
The ventilation operates only with the sunroof closed or in the tilted
position .
If the vehicle was switched off in the recircu lation mode, the air
conditioning automatically switches to fresh air operation.
Solar operation is not activated at low outside temperatures. •
Windshield defogging/defrosting

The windshield defogger works only when the engine is running.
The indicator light in the button illuminates when the windshield
defogger is turned on.
With a cold engine at outside temperatures below 41 °F (+5 °C) and
in !AUTO

® Air distribution
You can adjust the air circulation so that air flows from specific
vents.
• In the I isetting, al l the air flows from the vents in the center
conso le and the outle ts in the door pillars.
• In the-,!) setting, air flows from the outlets under the front seats.
• In the~ setting, air flows from outlets in the center console and

General
The basic settings for the climate control are performed in
the(SETUP] menu.
Fig. 141 MMI display:
Setup climate control
The basic settings for the air conditioning can only be made
with MMI turned on.
- Press the !SETUP] button in the controls to access the
menu.
- Select the desired function using the control knob (driver
or passenger) in the air conditioning controls.
The following functions can be selected:
• ECON
~ page 126
• Automatic recirculation ~ page 126
• Synchronization ~ page 127
• Center air vent~ page 127
• Rear seat operation* ~ page 127
• Solar operation* ~ page 127•
ECON
The ECON mode helps to save fuel.
The air conditioning is turned off in ECON mode. "ECON" means
"Economy". By switching off the air conditioning (compressor), you
save fuel.
Please note that vehicle interior temperature cannot be lower than
the outside temperature in the ECON mode. The air is not cooled or
dehumidified.
If the vehicle interior becomes too hot or if the windows fog up,
ECON mode should be turned off. As soon as the
( AUTO ] button in
the air conditioning controls is pressed, the system automatically leaves the ECON mode, and the air conditioning compressor is
turned on again .•
Automatic recirculation mode
An air quality sensor detects increased concentrations of
pollutants in the outside air and automatically switches
to recirculation mode.
We recommend that you always keep automatic air recirculation ON
to prevent polluted outside air from entering the vehicle interior.
If the
air quality sensor located in the air conditioning system
detects polluted outside air, the sensor decides whether the air
pollution can be reduced by the factory-installed pollutant filter or
whether it is necessary to switch to air recirculation . With heavy
concentrations of pollutants, the air conditioning system is
switched automatically to recirculation mode and the supply of
outside air is blocked. As soon as the concentration of pollutants in ..

_________________________________________________ w_ a_ r_ m __ a_n_ d_ c_ o_ld __ !II
the outside air drops, fresh air is supp lied to the veh icle interior
again .
In the event that the windows fog up during automatic air recircula­
tion, you must press the@ button immediately.
Under certa in operating cond itions, automatic air recirculation is
switched off automatically. With outside temperatures below about
-8 °C and in the ECON mode, automatic air recirculation is limited to
15 seconds. •
Synchronization
One climate control setting for all seats .
With synchronization active, the driver's or the passenger's settings
are adopted for the other seats . All the other settings that were
made are transferred to the other seats. This includes all the climate
control settings right down to the heated seats .
If a different setting is selected at a "synchron ized seat", synchroni ­
zation is cancelled. •
Center air vent
The temperature of the air leaving the center vents can be
changed to differ from the temperature setting .
Controls and equip­
ment
