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 selec‐
tor lever position D to R, N or M/S.▷Steptronic transmission: change from selec‐
tor lever position P to R, N, D or M/S.▷The vehicle begins rolling.▷Fogging of the windows when the auto‐
matic climate control is switched on.▷The vehicle battery charge is very low.▷Excessive cooling of the car's interior when
the heating is switched on.▷Manual transmission: low brake vacuum
pressure; this can occur, e.g., if the brake

tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are notnecessarily available in your car, e. g., due to
the selected options or country versions. This

NoteSufficient ventilation
When remaining in the vehicle for an ex‐
tended period of time, ensure sufficient exter‐
nal ventilation. Do not continuously use recircu‐
lated-air mode; otherwise the air quality in the
interior continuously deteriorates and window
condensation increases. ◀

sired program or the desired in‐
termediate setting.▷ Windows.▷ Upper body region.▷ Footwell.▷ Windows, upper body region, and foot‐
well.
Defrosts windows and removes
condensation
Direct the air distribution toward windows, in‐
crease the air flow and temperature, and, if
needed, use the cooling function.
Air flow, manual Turn the ring to set the desired
air volume.
The higher the rate, the more ef‐
fective the heating or cooling will
be.
The air flow from the air conditioner may be re‐
duced automatically to save battery power.
Temperature
Turn the ring to set the desired
temperature.
Cooling function
The car's interior can only be cooled with the
engine running.
Press button.
The air will be cooled and dehumidi‐
fied and, depending on the temperature set‐
ting, warmed again.
Depending on the weather, the windshield may
fog up briefly when the engine is started.
The air conditioner produces condensation wa‐
ter, refer to page 136, that will exit from below
the car.
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 condensation, recirculated
air mode switches off automatically after a cer‐
tain amount of time, depending on the external
temperature.
If the windows fog over, switch off recirculated-
air mode and increase the air flow, if needed.

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 con‐
trol: a sensor detects pollutants in the out‐
side air and shuts off automatically.▷Right LED on, recirculated-air mode: the
supply of outside air into the vehicle is per‐
manently blocked.
To prevent window condensation, recirculated
air mode switches off automatically after a cer‐
tain amount of time, depending on the external
temperature.
If windows are fogged over, switch off the recir‐
culating mode and press the AUTO button.
Make sure that air can flow to the windshield.
Sufficient ventilation
When remaining in the vehicle for an ex‐
tended period of time, ensure sufficient exter‐
nal ventilation. Do not continuously use recircu‐
lated-air mode; otherwise the air quality in the
interior continuously deteriorates and window
condensation increases. ◀

The Coasting driving condition is enabled under
certain conditions.
Under certain conditions the engine is auto‐
matically decoupled from the transmission in
selector lever position D. The vehicle continues
traveling with the engine idling to reduce fuel
consumption. Selector lever position D remains
engaged. An indicator provides information
about the distance traveled in Coasting mode.
In addition, context-sensitive instructions are
displayed to assist with an optimized fuel con‐
sumption driving style.
The achieved extended range is displayed in
the instrument cluster.
