will not start again automatically if any one of
the following conditions are met:
▷The driver's safety belt is unbuckled and
the driver's door is open.▷The hood was unlocked.
Some indicator lights light up for a varied
length of time.
The engine can only be started via the Start/
Stop button.
Functional limitations
Even if driving off was not intended, the deacti‐
vated engine starts up automatically in the fol‐
lowing situations:▷Excessive warming of the car's interior
when the cooling function is switched on.▷The steering wheel is turned.▷Steptronic transmission: change from se‐
lector lever position D to R, N or M/S.▷Steptronic transmission: change from se‐
lector lever position P to N, D, R or M/S.▷Fogging of the windows when the auto‐
matic climate control is switched on.▷Vehicle battery is heavily discharged.▷Excessive cooling of the car's interior when
the heating is switched on.

Climate control functions in detail
Switching the system on/off
Switching on
Set any air volume.
The AUTO program can also be switched on
directly via the AUTO button.
Switching off
Turn the rotary switch for the air volume, refer
to page 161, to 0. The blower and automatic
climate control are turned off entirely.
Temperature Turn the ring to set the desired
temperature.
The automatic climate control reaches this
temperature as quickly as possible, if needed
by increasing the cooling or heating output,
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 air in the car's interior will be cooled and
dehumidified and, depending on the tempera‐
ture setting, warmed again.
The car's interior can only be cooled with the
engine running.
Press button.
Air conditioning is switched on or off.
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 185, devel‐
ops that exits underneath the vehicle.
AUTO program Press button.
Air flow, air distribution and tempera‐
ture are controlled automatically.
Depending on the selected temperature and
outside influences, the air is directed to the
windshield, side windows, upper body, and
into the floor area.
The cooling function, refer to page 160, is
switched on automatically with the AUTO pro‐
gram.
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:▷LED off: outside air flows in continuously.▷LED on, recirculated-air mode: the supply
of outside air into the vehicle is perma‐
nently blocked.
To prevent window fogging, recirculated-air
mode switches off automatically after a certain
amount of time, depending on the environ‐
mental conditions.
With constant recirculated-air mode, the air
quality in the car's interior deteriorates and the
fogging of the windows increases.
If the windows fog over, switch off recircu‐
lated-air mode and increase the air flow, if
needed.

Air flow, manualTurn the ring to set the desired
air flow.
The higher the rate, the more ef‐
fective the heating or cooling
will be.
The air flow of the automatic climate control
may be reduced automatically to save battery
power.
Manual air distribution
Press buttons repeatedly to select a program:▷Windows.▷Upper body region.▷Floor area.
You may combine these programs as needed.
Defrosts windows and removes
condensation
Press button.
Ice and condensation are quickly re‐
moved from the windshield and the front side
windows.
Adjust air flow with the program active.
If the windows are fogged over, you can also
switch on the cooling function to dehumidify
the air.
Rear window defroster Press button.
The rear window defroster switches
off automatically after a certain period of time.
Microfilter
In external and recirculated air mode the mi‐
crofilter filters dust and pollen from the air.
This filter should be replaced during scheduled
maintenance, refer to page 226, of your vehi‐
cle.Seite 161Climate controlControls161

Maximum cooling Press button.
The system is set to the lowest tem‐
perature, optimum air flow and recirculated-air
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.
Adjust air flow with the program active.
AUTO program Press button.

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 floor area.
The cooling function, refer to page 163, 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.
To switch off the program: press the button
again or manually adjust the air distribution.
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 intensity.
The selected intensity is shown on the display
of the automatic climate control.
Automatic recirculated-air control/

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.
Recirculated-air mode switches off automati‐
cally at low external temperatures after a cer‐
tain amount of time in order to avoid window
fogging.

operated directly: any external tempera‐
ture.▷Battery is sufficiently charged.
If parked-car ventilation is switched on, the
vehicle battery will be discharged. Thus,
