Overview
Seat heating
Switching on Press button once for each tempera‐
ture level.
The maximum temperature is reached when
three LEDs are lit.
If the trip is continued within approx. 15 mi‐
nutes after a stop, seat heating is activated au‐
tomatically with the temperature selected last.
When ECO PRO is activated, the heater output
is reduced.
Switching off Press and hold the button, until the
LEDs go out.
Active seat ventilation, front
The concept The seat cushion and backrest surfaces are
cooled by means of integrated fans.
The ventilation cools the seat, e.g., if the vehi‐
cle interior is overheated or for continuous
cooling at high temperatures.
Overview
Active seat ventilation
Switching on Press button once for each ventilation
level.
The highest level is active when three LEDs
are lit.
After a short time, the system automatically
moves down one level in order to prevent ex‐
cessive cooling.

Temperature
Turn the ring to set the desired
temperature.
The automatic climate control achieves this
temperature as quickly as possible, if needed
by using the maximum cooling or heating ca‐
pacity, 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 air in the car's interior will be cooled and
dehumidified and, depending on the tempera‐
ture setting, warmed again.
The car's interior can only be cooled with the
engine running.
Press button.
Air conditioning is switched on or off.
Depending on the weather, the windshield and
side windows may fog up briefly when the en‐
gine is started.
The cooling function is switched on automati‐
cally with the AUTO program.
When using the automatic climate control,
condensation water, refer to page 187, devel‐
ops that exits underneath the vehicle.
Maximum cooling Press button.
The system is set to the lowest tem‐
perature, optimum air flow and recirculated-air
mode.
Air flows out of the vents to the upper body re‐
gion. The vents need to be open for this.
The function is available above an external
temperature of approx. 32 ℉/0 ℃ and with the
engine running is indicated.
Adjust air flow with the program active.
AUTO program Press button.
Air flow, air distribution and tempera‐
ture are controlled automatically.
Depending on the selected temperature,
AUTO intensity program and outside influen‐
ces, the air is directed to the windshield, side
windows, upper body, and into the floor area.
The cooling function, refer to page 163, is
switched on automatically with the AUTO pro‐
gram.
At the same time, a condensation sensor con‐
trols the program so as to prevent window
condensation as much as possible.
Intensity of the AUTO program
With the AUTO program activated, the auto‐
matic intensity control can be changed.Seite 163Climate controlControls163

condensation
Press button.
Ice and condensation are quickly re‐
moved from the windshield and the front side
windows.
For this purpose, point the side vents onto the
side windows as needed.
Adjust air flow with the program active.
If the windows are fogged over, you can also
switch on the cooling function or press the AUTO button to utilize the condensation sen‐
sor.
Rear window defroster Press button.
The rear window defroster switches
off automatically after a certain period of time.
Microfilter/activated-charcoal filter
The microfilter removes dust and pollen from
the incoming air.
The activated-charcoal filter removes gaseous
pollutants from the outside air that enters the
vehicle.
This combined filter should be replaced during
maintenance, refer to page 226, of the vehicle.

operated directly: any external tempera‐
ture.▷Battery is sufficiently charged.
If parked-car ventilation is switched on, the
vehicle battery will be discharged. Thus,
limit the maximum activation time to save
the vehicle battery. The system will be
available again after engine starting and/or
a short trip.▷Make sure that the vehicle's date and time
are set correctly.
