[ i] Tips
• Residual heat: With the ignition turned off, you can activate the
residual heat function by pressing the
!ECON ON/OFFJ button. The
residual heat from the coolant can be used to heat the vehicle inte­
rior. The residual heat function is turned off automatically after 30
minutes.
• Synchronizing climate control: By pressing and holding the
control knob on the driver's side, the temperature setting on the
driver's side can be switched to the passenger's side, and vice versa.
The new temperature is shown in the display .
• The grille between the
!ECON ON/OFF] and !SETUP ] buttons
must remain unobstructed and must not be taped over. Measuring
sensors are located behind it.•

Turning on and off [ECON ON /OFF]
Turning th e air conditioning on
- Press [ECON ON/OF F] briefly, or
- Press [AUTO].
Turning the air conditioning off
-Press the !ECON ON/OFF] button for at least 2 seconds to
switch the a ir cond itioning off and to block the air supply
f rom the outs ide .
"O FF" appears in the display.
Sw itchin g air c ondit ioning on /off
- Switching the air conditioning system on/off is done with
climate contro l switched on.
- Press the !ECON ON/OFF] button just
briefly.
The air conditioner turns back on if you press one of the control
buttons or the contro l knob.
ECON operation is indicated by the glowing LED on the right next to
the word ECON.
The air conditioning (compressor) is turned off in ECON mode .
"ECON" means "Economy" . You save fuel by switching off the air
conditioning=>
page 119.
Please note that vehicle interior temperature cannot be lower than
the outside temperature in the ECON mode. The air is no t cooled or
dehumidified. This can cause the windows to fog up.
[ i ) Tip s
Residu al he at: With the ignition turned off, you can activate the
residual heat function by pressing the !ECON ON/OFF] button. The
residual heat from the coo lant can be used to heat the vehic le inte-

rior. The residual heat function is turned off automatical ly after 30
minutes .•
Aut omati c mod e [AUTO ]
The automatic mode is the standard setting for all
seasons.
Turning on AUTO
- Selec t temperature be tween 60 °F (+ 1 6 °C) and 84 °F
(+28 °C) .
-Press [AUTO]~ page 112, fig. 109.
Automatic operation ensures constant temperatures in the interior and dehumidifies the air inside the vehicle . Air temperature, volume
and distribution are controlled automatically to reach or maintain
the desired interior temperature as quickly as possib le. Fluctuations
in exter ior temperature and the effects of temperature from the
position of the sun are compensated for automatica lly.
This operating mode works only in the adjustable temperature range, from 60 °F ( + 16 °C) to 84 °F ( +28 °C). If a temperature below
60 °F (+16 °C) is se lected,
LO appears in the display. At temperatures
above 84 °F (+28 °Cl,
HI is displayed. At both extreme settings,
climate control runs continuously at maximum cooling or heating
power. There is no temperature regulation. •

The air outlets are actuated either automatically or manually
depending on the operating mode selected. Heated or unheated
fresh air, or cooled air flows from the vents.
The air outlets to heat the rear footwell are located under the front
seats .
[ i] 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 control 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 conditioner only when necessary. Also please
note the following points:
- If you want to save fuel, activate ECON.
- If you are going to drive with the windows open, use
ECON.
If the vehicle is extremely hot due to the heat of the sun,
briefly open doors and windows.
~ 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. •
Controls and equip­
ment
App lies to vehic les: with solar sliding/ti lt ing sunroof
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.
The blower 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 118.
The v entilation operates only with the sunroof closed or in the tilted
position.
If the vehicle was switched off in the recirculation mode, the air
conditioning automatically switches to fresh air operation.
Solar operation is not activated at low outside temperatures. •

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 vehic le interior temperature cannot be lower than
the outs ide temperature in the ECON mode . The air is not cooled or
dehumidified.
If the vehic le interior becomes too hot or if the windows fog up,
ECON mode should be turned off . As soon as the !AUTO
I button in
the air conditioning controls is p ressed, the system automatically
leaves the ECON mode, and the air conditioning compressor is
turned on again .•
Automatic recirculation mode
An air quality sensor detects incre ased concentratio ns of
pollutants in the outside air and aut omatically switches
to recirculation mode.
We recommend that you always keep automatic air recirculation ON
to prevent polluted outside air from entering the vehicle interior .
I f the
air qualit y sensor located in the air conditioning system
detects po lluted outside air, the sensor decides whether the air
pol lution can be reduced by the factory -installed po llutant filter or
whe ther it is necessary to swi tch to air recirculatio n. With heavy
concentrations of pol lutants, the air conditioning system is
sw itched automatically to rec irculation mode and the supp ly of
outside air is blocked . As soon as the concentration of pollutants in
the outside a ir drops, fresh air is supp lied to the vehic le inte rior
aga in.
I n the event that the windows fog up during automatic air recircu la ­
t ion, you must press the® button immed iately.
Under certain operating conditions , automatic air recircu lation is
sw itched off automatically. With outside temperatures be low about
+10 °C , automatic air recirculation is limited to 30 seconds. With
outside temperatures below about -1 °C and in the ECO N mode,
automatic air recirculation is limited to 15 seconds .•
Synchronization
One climate control se tting f or all seats.
With synchronization active, the driver 's or the passenger's settings
are adopted for the other seats . Al l the other settings that were
made are trans ferred to the other seats. This includes all the c limate
control settings right down to the heated seats.
I f a differen t setting is selected at a "synchronized seat", synchroni ­
z ation is cancelled .•

Ce nter air vent
The air flow coming from the center vents can be adjusted to be
colder or warmer than the selected set temperature.
In this way you have the opportunity to have the air flow from the
center vents a little warmer or cooler, depending on the time of year.
A little cooler in the summer and a little warmer in the winter .•
Ap plies t o vehicles: with solar roof
Solar operation
With sufficient sunlight, the stationary ventilation fan
continues to operate with solar energy to bring in fresh air
after the ignition has been switched off.
- Switch solar operation to on.
The 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 118.
The ventilation operates only with the sunroof closed or in the tilted
position.
Con tro ls and eq uip­
ment
If the vehicle was switched off in the recirculation mode, the air
conditioning automatically switches to fresh air operation .
Solar opera tion is not activated at low temperatures .•
