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 air conditioner produces condensation
water, refer to page 171, that will exit from be‐
low the car.
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.
With constant recirculated-air mode, the air
quality in the car's interior deteriorates and the
fogging of the windows increases.
If the windows fog over, switch off recircu‐
lated-air mode and increase the air flow, if
needed.
Air flow, manual Press the left or right side of the but‐
ton: decrease or increase air flow.
The intensity is indicated through LEDs. The
highest level is active when seven LEDs are lit.
The air flow from the air conditioner may be re‐
duced automatically to save battery power.

The selected temperature is shown on the dis‐
play of the automatic climate control.
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
