Starting the engine
The engine starts automatically under the fol‐
lowing conditions:
▷Automatic transmission:
By releasing the brake pedal.▷Manual transmission:
The clutch pedal is pressed.
After the engine starts, accelerate as usual.

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 lamps light up for varying
lengths of time.
The engine can only be started via the Start/
Stop button.
Note
Even if driving away was not intended, the de‐
activated engine starts up automatically in the
following situations:▷Excessive warming of the passenger com‐
partment when the cooling function is
switched on.▷The steering wheel is turned.▷Automatic transmission: change from se‐
lector lever position D to N, R or M/S.▷Automatic transmission: change from se‐
lector lever position P to N, D, R or M/S.▷The vehicle begins rolling.▷Fogging of the windows when the auto‐
matic climate control is switched on.▷Vehicle battery is heavily discharged.▷Excessive cooling of the passenger com‐
partment when the heating is switched on.▷Low brake vacuum pressure; this can oc‐
cur, for example, if the brake pedal is de‐
pressed a number of times in succession.
Activating/deactivating the system

sired program or the desired in‐
termediate setting.▷ Windows.▷ Upper body region.▷ Windows, upper body region, and foot‐
well.▷ Footwell.
Defrosting windows and removing
condensation
Direct the air distribution toward windows, in‐
crease the air flow and temperature, and, if
necessary, use the cooling function.
Rear window defroster Press the button.
The rear window defroster switches
off automatically after a certain period of time.
Air flow, manual Press the left or right side of the but‐
ton: decrease or increase air flow.
The air flow of the air conditioner may be re‐
duced automatically to save battery power.
AUTO program Press the 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 footwell.
The cooling function, refer to page 142, is
switched on automatically with the AUTO pro‐
gram.
Temperature Turn the wheel to set the de‐sired temperature.
The automatic climate control reaches this
temperature as quickly as possible, if neces‐
sary by increasing the cooling or heating out‐
put, and then keeps it constant.
Avoid rapidly switching 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 passenger compartment can only be
cooled with the engine running.
Press the button.
The air is cooled and dehumidified
and, depending on the temperature setting,
warmed again.
Depending on the weather, the windshield may
fog up briefly when the engine 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 164, devel‐
ops that exits underneath the vehicle.
Recirculated-air mode You can 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.

Air flow, air distribution, and temperature 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 145, 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.
Intensity of the AUTO program
With the AUTO program switched on, auto‐
matic control of the air flow and air distribution
can be adjusted.
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.
Maximum cooling Press the button.
The system is set to the lowest tem‐
perature, maximum air flow and air circulation
mode.
Air flows out of the vents for the upper body
region. 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.
The air flow can be adjusted when the program
is active.
Cooling function
The passenger compartment can only be
cooled with the engine running.
Press the button.The air is cooled and dehumidified and, de‐
pending on the temperature setting, warmed
again.
Depending on the weather, the windshield may
fog up briefly when the engine is started.

ops that exits underneath the vehicle.
Automatic recirculated-air control/
recirculated-air mode
You can 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 the 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 controls the shutoff auto‐
matically.▷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 window fog‐
ging.
If the windows are fogged over, switch off the
recirculated-air mode and press the AUTO
button to utilize the condensation sensor.
Make sure that air can flow onto the wind‐
shield.
Continuous recirculated-air mode
The recirculated-air mode should not be
used for an extended period of time, as the air
quality inside the vehicle deteriorates stead‐
ily.◀

ture, or slowly adjusting the rate of heating or
cooling of the passenger compartment, fuel
consumption can be economized.
