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 147, is
switched on automatically with the AUTO pro‐
gram.
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.

cally with the AUTO program.
When using the automatic climate control,
condensation water, refer to page 172, devel‐
ops that exits underneath the vehicle.
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.Seite 147Climate controlControls147

tween the minimum and maximum marks.The marks are on the side of the coolant
reservoir.SymbolMeaningMaximumMinimum
Adding
1.Let the engine cool.2.Turn the lid of the coolant reservoir slightly
counterclockwise to allow any excess
pressure to dissipate, then open it.3.If the coolant is low, slowly add coolant up
to the specified level; do not overfill.4.Turn the lid until there is an audible click.
The arrows on the coolant reservoir and
the lid must point towards one another.5.Have the cause of the coolant loss elimi‐
nated as soon as possible.
