Interior air quality
The air quality inside the vehicle is improved by
an emissions-tested interior, a microfilter, and a
climate-control system for regulating tempera‐
ture, air flow, and recirculated-air mode.
This chapter describes all standard, country-spe‐
cific and optional features offered with the series.
It also describes features that are not necessarily
available in your vehicle, e. g., due to the selected
options or country versions. This also applies to
safety-related functions and systems. When us‐
ing these functions and systems, the applicable
laws and regulations must be observed.
In addition there are other functions which de‐
pend on the vehicle's equipment, for instance
microfilter/activated-charcoal filter, automatic cli‐
mate control with automatic recirculated-air con‐
trol AUC, and parked-car ventilation.

Press button.
Switching on
The LED is illuminated with air condi‐
tioning switched on.
Press any button except for the following:
▷ Rear window defroster.
▷ Seat heating.
Depending on the weather, the windshield and
side windows may fog up briefly when the en‐
gine is started.
Switching off
The air conditioning is switched on automatically
with the AUTO program.
Press the left button for the minimum
speed.
When using the automatic climate control, con‐
densation water, refer to page 229, develops
and drains underneath the vehicle. This is nor‐
mal.
Temperature
Concept
AUTO program
The automatic climate control achieves the set
temperature as quickly as possible, if necessary
by using the maximum cooling or heating power,
and then keeps it constant.
Concept
Air flow, air distribution and temperature are con‐
trolled automatically.
Settings
Switching on/off
Turn the ring to set the desired
temperature.
Press button.
The LED is illuminated with the AUTO
program switched on.
Depending on the selected temperature and out‐
side influences, the air is directed to the wind‐
shield, side windows, upper body, and into the
floor area.
Do not rapidly switch between different tempera‐
ture settings. Otherwise, the automatic climate
control will not have sufficient time to adjust the
set temperature.
The air conditioning, refer to page 201, is
switched on automatically with the AUTO pro‐
gram.
Air conditioning
Concept
The air in the car's interior will be cooled and de‐
humidified and, depending on the temperature
setting, warmed again.

Concept
Concept
You may react to unpleasant odors or pollutants
in the immediate environment by temporarily
suspending the supply of outside air. The system
then recirculates the air flow within the vehicle.
The air distribution for climate control can be ad‐
justed manually.
Operation
Operation
Turn the wheel to select the de‐
sired program or the desired in‐
termediate setting.
Press button repeatedly to select an op‐
erating mode:
▷ LED off: outside air flows in continuously.
▷ LED on, recirculated-air mode: the supply of
outside air into the vehicle is permanently
blocked.

Defrosting windows and removing
condensation
Make the following settings to defrost the win‐
dows and remove condensation:
With constant recirculated-air mode, the air qual‐
ity in the car's interior deteriorates and the fog‐
ging of the windows increases.
If the windows fog over, switch off recirculated-
air mode and increase the air flow, if needed.
▷ Direct the air distribution onto the windows.
▷ Increasing the air flow.
Controlling the air flow manually
▷ Increase the temperature.
▷ Switch on the air conditioning if needed.
Concept
The air flow for climate control can be adjusted
manually.
Rear window defroster
Press button. The LED lights up.
Operation
The rear window defroster switches off
automatically after a certain period of time.
Press the left or right side of the button:
decrease or increase air flow.
Microfilter
In external and recirculated-air mode the microfil‐
ter filters dust and pollen from the air.
The air flow from the air conditioner may be re‐
duced automatically to save battery power.
Have this filter changed during vehicle mainte‐
nance, refer to page 274.

Maximum cooling
Concept
Settings
The system is set to the lowest temperature, op‐
timum air flow and recirculated-air mode.
Turn the ring to set the desired
temperature.
General information
The function is available above an external tem‐
perature of approx. 32 ℉/0 ℃ And with the en‐
gine running.
The automatic climate control reaches this tem‐
perature as quickly as possible, if needed, by in‐
creasing the cooling or heating output, and then
keeps it constant.
Switching on/off
Press button.
Do not rapidly switch between different tempera‐
ture settings. Otherwise, the automatic climate
control will not have sufficient time to adjust the
set temperature.
The LED is illuminated with the system
switched on.
Air flows out of the vents to the upper body re‐
gion. The vents need to be open for this.

Depending on the weather, the windshield and
side windows may fog up briefly when the en‐

Depending on the selected temperature, the in‐
tensity of the AUTO program, and outside influ‐
ences, the air is directed to the windshield, side
windows, upper body, and into the floor area.
The air conditioning is switched on automatically
with the AUTO program.
The air conditioning, refer to page 204, is
switched on automatically with the AUTO pro‐
gram.
When using the automatic climate control, con‐
densation water, refer to page 229, develops
and drains underneath the vehicle. This is nor‐
mal.
At the same time, a condensation sensor con‐
trols the program so as to prevent window con‐
densation as much as possible.

CONTROLS
In the AUTO program, the air flow may be re‐
duced during a phone call on the hands-free sys‐
tem.
Recirculated-air mode switches off automatically
at low external temperatures after a certain
amount of time in order to avoid window fogging.
If the windows are fogged over, switch off the re‐
circulated-air mode and press the AUTO button
to utilize the condensation sensor. Make sure
that air can flow to the windshield.
Intensity
With the AUTO program switched on, the inten‐
sity can be set. This changes the automatic con‐
trol for the air flow and air distribution.
Controlling the air flow manually
Press the left or right side of the button:
decrease or increase intensity.
Concept
The selected intensity is shown on the display of
the automatic climate control.
The air flow for climate control can be adjusted
manually.
Automatic recirculated-air control/
recirculated-air mode
General information
To manually adjust air flow switch off AUTO pro‐
gram first.
Concept
The automatic recirculated-air control AUC rec‐
ognizes odors or pollutants in the outside air.
The outside air supply is shut off and the interior
air is recirculated.
Operation
Press the left or right side of the button:
decrease or increase air flow.
The selected air flow is shown on the display of
the automatic climate control.
General information
If the system is activated, a sensor detects pollu‐
tants in the outside air and controls the shut-off
automatically.
The air flow of the automatic climate control may
be reduced automatically to save battery power.
If the system is deactivated, outside air continu‐
ously flows into the car's interior.
Controlling the air distribution
manually
With constant recirculated-air mode, the air qual‐
ity in the car's interior deteriorates and the fog‐
ging of the windows increases.
Concept
The air distribution for climate control can be ad‐
justed manually.
