Climate control functions in detail
Switching the system on/off
Switching on
Press any button except:▷Rear window defroster.▷Left side of Air volume button.▷Seat heating.▷Seat ventilation.▷If necessary, SYNC program.
Switch off
▷Complete system: Press and hold the left button on
the driver's side until the control
clicks off.▷On the front passenger side:
Press and hold the left button on
the front passenger side.
Temperature
Turn the ring to set the desired
temperature.
The automatic climate control achieves this
temperature as quickly as possible, if needed
by using the maximum cooling or heating ca‐
pacity, and then keeps it constant.
Do not rapidly switch between different tem‐
perature settings. Otherwise, the automatic cli‐
mate control will not have sufficient time to ad‐
just the set temperature.
Cooling function
The car's interior can only be cooled with the
engine running.
Press button.
The air will be cooled and dehumidified and,
depending on the temperature setting,
warmed again.
Depending on the weather, the windshield and
side windows may fog up briefly when the en‐
gine is started.
The cooling function is switched on automati‐
cally with the AUTO program.
When using the automatic climate control,
condensation water, refer to page 195, devel‐
ops that exits underneath the vehicle.
Maximum cooling Press button.
The system is set to the lowest tem‐
perature, optimum air flow and air circulation mode.
Air flows out of the vents to the upper body re‐
gion. The vents need to be open for this.
The function is available above an external
temperature of approx. 32 ℉/0 ℃ and with the
engine running is indicated.
Adjust air flow with the program active.
AUTO program Press button.
Air flow, air distribution and tempera‐
ture are controlled automatically.
Depending on the selected temperature,
AUTO intensity program and outside influen‐
ces, the air is directed to the windshield, side
windows, upper body, and into the footwell.
The cooling function, refer to page 168, is
switched on automatically with the AUTO pro‐
gram.
At the same time, a condensation sensor con‐
trols the program so as to prevent window
condensation as much as possible.Seite 168ControlsClimate control168

Intensity of the AUTO program
With the AUTO program activated, the auto‐
matic intensity control can be changed.
Press the left or right side of the but‐
ton: decrease or increase the inten‐
sity.
The selected intensity is shown on the display
of the automatic climate control.
Automatic recirculated-air control/
recirculated-air mode
You may respond to unpleasant odors or pollu‐
tants in the immediate environment by tempo‐
rarily suspending the supply of outside air. The
system then recirculates the air currently
within the vehicle.
Press button repeatedly to select an
operating mode:▷LEDs off: outside air flows in continuously.▷Left LED on, automatic recirculated-air
control: a sensor detects pollutants in the
outside air and shuts off automatically.▷Right LED on, recirculated-air mode: the
supply of outside air into the vehicle is per‐
manently blocked.
With constant recirculated-air mode, the air
quality in the car's interior deteriorates and the
fogging of the windows increases.
If the windows are fogged over, switch off the
recirculated-air mode and press the AUTO
button on the driver's side to utilize the con‐
densation sensor. Make sure that air can flow
to the windshield.
Air flow, manual To manually adjust air flow turn off AUTO pro‐
gram first.
Press the left or right side of the but‐
ton: decrease or increase air flow.
The selected air flow is shown on the display of
the automatic climate control.
The air flow of the automatic climate control
may be reduced automatically to save battery
power.
Manual air distribution Press button repeatedly to select a
program:▷Upper body region.▷Upper body region and footwell.▷Footwell.▷Windows and footwell.▷Windows, upper body region, and footwell.▷Windows: driver's side only.▷Windows and upper body region.
If the windows are fogged over, press the
AUTO button on the driver's side to utilize the
condensation sensor.
SYNC program The current settings on the driver's
side for temperature, air flow, air distri‐
bution, and AUTO program are transferred to the front passenger side and to the left and
right rear.
The program is switched off if the settings on
the front passenger side or in the rear are
changed.
Residual heat The heat stored in the engine is used to heat
the interior.
Functional requirement
▷Up to 15 minutes after switching off the
engine.▷Warm engine.▷The battery is sufficiently charged.▷External temperature below 77 ℉/25 ℃.
The availability of the function is shown on the
display of the automatic climate control.

Press button.
Ice and condensation are quickly re‐
moved from the windshield and the front side
windows.
For this purpose, point the side vents onto the
side windows as needed.
Adjust air flow with the program active.
If the windows are fogged over, you can also
switch on the cooling function or press the AUTO button to utilize the condensation sen‐
sor.
Rear window defroster Press button.
The rear window defroster switches
off automatically after a certain period of time.
Microfilter/activated-charcoal filter
The microfilter removes dust and pollen from
the incoming air.
The activated-charcoal filter removes gaseous
pollutants from the outside air that enters the
vehicle.
This combined filter should be replaced during
scheduled maintenance, refer to page 238, of
your vehicle.

rectly or by using two preset departure times.
The reel-on time is automatically determined
based on the temperature. The system
promptly switches on before the selected de‐
parture time.
Operation can be performed via iDrive.

▷When the departure time is preselected:
depends on internal, external and set tem‐
perature.▷Direct operation: any external temperature.
Open the vents to allow air to flow out.
