Starting the engine
The engine starts automatically under the fol‐
lowing conditions:
▷Steptronic transmission:
By releasing the brake pedal.▷Manual transmission:

Some indicator lights light up for a varied
length of time.
The engine can only be started via the Start/
Stop button.

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.▷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 car's interior when
the heating is switched on.▷Low brake vacuum pressure; this can oc‐
cur, e.g., if the brake pedal is depressed a
number of times in succession.

Washer fluid reservoir
All washer nozzles are supplied from one res‐
ervoir.
Fill with a mixture of windshield washer con‐
centrate and tap water and – if required – with a
washer antifreeze, according to the manufac‐
turer's recommendations.
Mix the washer fluid before adding to find the
right mixture.
Do not add windshield washer concentrate and
antifreeze undiluted and do not fill with pure
water; this could damage the wiper system.
Do not mix window washer concentrates of dif‐
ferent manufacturers because they can clog
the windshield washer nozzles.
Recommended minimum fill quantity:
0.2 US gal/1 liter.

Shifting Shifting into 5th or 6th gear
When shifting into 5th or 6th gear, push
the gearshift lever to the right; otherwise, inad‐
vertent shifting into 3rd or 4th gear could lead
to engine damage.◀
Reverse gear Select only when the vehicle is stationary.
To overcome the resistance push the selector
lever dynamically to the left and engage the re‐
verse gear.

Selector lever positions
D Drive Selector lever position for normal vehicle oper‐
ation. All gears for forward travel are activated
automatically.
R is Reverse
Select only when the vehicle is stationary.
N Neutral: The vehicle may roll. Use in automatic car
washes, e.g.
When the ignition is switched off, refer to
page 67, selector lever position P is engaged
automatically.
P Park Select only when the vehicle is stationary. The
drive wheels are blocked.
P is engaged automatically:▷After the engine is switched off when the
vehicle is in radio-ready state, refer to
page 67, or when the ignition is switched
off, refer to page 67, and when selector
lever position R or D is set.▷With the ignition off, if selector lever posi‐
tion N is set.▷If the driver's safety belt is released, the
driver's door is opened, and the brake
pedal is not pressed while the vehicle is
stationary and selector lever position D or
R is set.
Before exiting the vehicle, make sure that se‐
lector lever position P is set. Otherwise, the ve‐
hicle may begin to move.

sired program or the desired in‐
termediate setting.▷ Windows.▷ Upper body region.▷ Windows, upper body region, and foot‐
well.▷ Footwell.
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.
Rear window defroster Press 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 from the air conditioner may be re‐
duced automatically to save battery power.
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 footwell.
The cooling function, refer to page 136, is
switched on automatically with the AUTO pro‐
gram.
Convertible program
When the convertible top is open, the
convertible program is activated as well. In the
convertible program, the automatic climate
control is optimized for driving with the
convertible top open. In addition, the air flow is
increased as the vehicle speed increases.
The efficiency of the convertible program can
be greatly enhanced by installing the wind de‐
flector.
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 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 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.Seite 136ControlsClimate control136

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.
Recirculated air mode switches off automati‐
cally at low external temperatures after a cer‐
tain amount of time in order to avoid window
fogging.
If the windows fog over, switch off recircu‐
lated-air mode and increase the air flow, if
needed.
Sufficient ventilation
When remaining in the vehicle for an ex‐
tended period of time, ensure sufficient exter‐
nal ventilation. Do not continuously use recir‐
