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.
Cooling function
The passenger compartment can only be
cooled with the engine running.
Rear window defroster
Press the button.
Press the button.
The rear window defroster switches
off automatically after a certain period of time.
The air is cooled and dehumidified
and, depending on the temperature setting,
warmed again.
Air flow, manual
Depending on the weather, the windshield may
fog up briefly when the engine is started.
Press the left or right side of the but‐
ton: decrease or increase air flow.
The cooling function is switched on automati‐
cally with the AUTO program.
The air flow of the air conditioner may be re‐
duced automatically to save battery power.
When using the automatic climate control,

ops that exits underneath the vehicle.
AUTO program
Press the button.
Recirculated-air mode
Air flow, air distribution, and tempera‐
ture are controlled automatically.
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.
Depending on the selected temperature and
outside influences, the air is directed to the
windshield, side windows, upper body, and
into the footwell.
Press the button repeatedly to select
an operating mode:

Temperature
With the AUTO program switched on, auto‐

can be adjusted.
Turn the wheel to set the de‐
sired temperature.
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.
The automatic climate control reaches this
temperature as quickly as possible, if neces‐

put, and then keeps it constant.
Maximum cooling
Press the button.
Avoid rapidly switching between different tem‐
perature settings. Otherwise, the automatic cli‐
mate control will not have sufficient time to ad‐

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.
AUTO program
Press the button.
The air is cooled fastest when the engine is
running.
Air volume, air distribution, and tem‐
perature are controlled automatically.
The air volume can be adjusted when the pro‐
gram is active.
Depending on the selected temperature, the
AUTO intensity, and outside influences, the air
