SafetyVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and sys‐
tems.
Airbags
The following airbags are located under the
marked covers:1Front airbags2Side airbags in the seat backrests3Knee airbag
Front airbags
Front airbags help protect the driver and pas‐
senger by responding to frontal impacts in
which safety belts alone cannot provide ade‐
quate restraint.
Side airbags
In a lateral impact, the side airbag protects the
side of the body in the chest area.
Knee airbag
The knee airbag supports the legs in a frontal
impact.
Protective action
Airbags are not triggered in every impact situa‐
tion, e.g., in less severe accidents or rear-end
collisions.
Even when all instructions are followed closely,
injury from contact with the airbags cannot be
ruled out in certain situations.
The ignition and inflation noise may lead to
short-term and, in most cases, temporary hear‐
ing impairment in sensitive individuals.
Information on how to ensure the optimal
protective effect of the airbags▷Keep at a distance from the airbags.▷Always grasp the steering wheel on the
steering wheel rim, holding your hands at
the 3 o'clock and 9 o'clock positions, to keep
the danger of injury to your hands or arms as
low as possible if the airbag is triggered.▷There should be no people, animals, or ob‐
jects between an airbag and a person.▷Do not use the cover of the front airbag on
the front passenger side as a storage area.▷Keep the dashboard and window on the
front passenger side clear, i.e., do not cover
with adhesive labels or coverings, and do not
attach holders such as for navigation instru‐
ments and mobile phones.▷Make sure that the front passenger is sitting
correctly, i.e., keeps his or her feet and legs
in the footwell; otherwise, leg injuries can
occur if the front airbag is triggered.▷Do not place slip covers, seat cushions or
other objects on the front passenger seat
that are not approved specifically for seats
with integrated side airbags.Seite 73SafetyControls73

Direct the flow of air to the win‐
dows
, to the upper body area
, or to the knee area and foot‐
well
. Intermediate positions are
possible. In the 6 o'clock position, a
small amount of air is also directed toward the
windows to keep them from fogging over.
Recirculated air mode If the air outside the car has an un‐
pleasant odor or contains pollu‐
tants, shut off the supply to the interior of the car
temporarily. The system then recirculates the air
currently within the vehicle.
The recirculated air mode can also be activated/
deactivated, refer to page 12, via a button on the
steering wheel.
Only use recirculated air mode for a limited
period
If condensation starts to form on the inside win‐
dow surfaces during operation in the recircu‐
lated air mode, you should switch it off while also
increasing the air flow rate as required. The re‐
circulated air mode should not be used contin‐
uously for lengthy periods; otherwise, the qual‐
ity of the air inside the car will gradually
deteriorate.◀
Air volume Press the corresponding button.
The higher the rate, the more ef‐
fective the heating or cooling will
be.
The air flow rate may be reduced or the blower
may be switched off entirely to save on battery
power.
Switching the system on/off Press the left button at the mini‐
mum fan speed. The blower and air
conditioner are completely
switched off and the air supply is cut off.Seite 90ControlsClimate90
Online Edition for Part no. 01 40 2 609 184 - 09 11 500

To switch on the air conditioner, set the desired
air flow rate.
Switching cooling function on/off The cooling function cools and de‐
humidifies the incoming air before
reheating it as required, according to the tem‐
perature setting. This function is only available
while the engine is running.
The cooling function helps to prevent conden‐
sation on the windows or to remove it quickly.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
Rear window defroster The defroster switches off auto‐
matically after a certain time or
when the hardtop is opened.
Temperature To increase the temperature, turn
the rotary switch clockwise to‐
wards red. For a lower temperature,
turn the rotary switch counter‐
clockwise towards blue.

Air distribution, manual
Depending on the selected setting, the air is di‐
rected to the windshield, to the upper body area,
to the knee area and into the footwell.
Adjusting air distribution manually Press the button repeatedly until
the air distribution is set as re‐
quired. The corresponding LED lights up.
The manual air distribution is also switched on
when the AUTO program is deactivated.Temperature
Set the desired temperatures indi‐
vidually for the driver's and passen‐
ger sides.
The automatic climate control ach‐
ieves this temperature as quickly as possible re‐
gardless of the season, using maximum cooling
or heating power if necessary, and then main‐
tains it.
To give the automatic climate control enough
time to achieve the set temperature, do not
switch between different temperature settings
in quick succession.
Maximum heating power can be obtained with
the highest setting, regardless of the external
temperature.
The lowest setting effects continuous cooling.Seite 92ControlsClimate92
