Temperature distribution
The heating action in the seat cushion and back‐
rest can be distributed in different ways.1."Climate"2."Seat heating distribution"3.Select the required seat.4.Turn the controller to set the temperature
distribution.
Rear seat heating
Switching on
Press the button once for each temper‐
ature level.
The maximum temperature is reached when
three LEDs are lit.
If the drive is continued within approx. 15 mi‐
nutes, the seat heating is activated automati‐
cally with the temperature selected last.
Switching off Press the button longer.
The LEDs go out.
Active seat ventilation, front
The seat cushion and backrest surfaces are
cooled by means of integrated fans.
The ventilation rapidly cools the seat, e. g., if the
vehicle interior is overheated or for continuous
cooling at high temperatures.
Switching on
Press the button once for each ventila‐
tion level.
The highest level is active when three LEDs are
lit.
If when the seat ventilation is turned on the Max‐
imum Cooling function is activated, the seat
ventilation automatically switches to the highest
level. When the Maximum Cooling function is
switched off, the unit switches back to the pre‐
viously set level.
After a short time, the system automatically
moves down one level in order to prevent ex‐
cessive cooling.
Switching off Press the button longer.
The LEDs go out.

Climate control functions in detail
Manual air distribution Press the button repeatedly to select a
program:▷Upper body region.▷Upper body region and footwell.▷Footwell.▷Windows and footwell: driver's side only.▷Windows, upper body region and footwell:
driver's side only.
If the windows are fogged over, press the AUTO
button on the driver's side to utilize the conden‐
sation sensor.
Temperature Turn the wheel to set the desired
temperature.
The automatic climate control achieves this
temperature as quickly as possible, if necessary
with the maximum cooling or heating capacity,
and then keeps it constant.
Avoid rapidly switching between different tem‐
perature settings. The automatic climate control
will not have sufficient time to adjust the set
temperature.
AUTO program Press the button.
Air volume, air distribution, and tem‐
perature are controlled automatically.
Depending on the selected temperature, AUTO
intensity, and outside influences, the air is di‐
rected to the windshield, side windows, upper
body, and into the footwell.
The cooling function, refer to page 133, 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 con‐
densation as much as possible.
Intensity of the AUTO program
With the AUTO program switched on, automatic
control of the air volume and air distribution can
be adjusted.
Press the left or right side of the button:
decrease or increase the intensity.
The selected intensity is shown on the display
of the automatic climate control.
Air volume, manual
To be able to manually adjust the air volume,
switch off the AUTO program first.
Press the left or right side of the button:
decrease or increase air volume.
The selected air volume is shown on the display
of the automatic climate control.
The air volume of the automatic climate control
may be reduced automatically to save battery
power.
Defrosting windows and removing
condensation
Press the button.
Ice and condensation are quickly re‐
moved from the windshield and the front side
windows.
The air volume can be adjusted when the pro‐
gram is active.
If the windows are fogged over, additionally
switch on the cooling function or press the
AUTO button to utilize the condensation sensor.
Maximum cooling Press the button.Seite 132ControlsClimate control132

The system is set to the lowest temperature,
maximum air flow and recirculated-air mode.
Air flows out of the vents for the upper body re‐
gion. Open them for this purpose.
Air is cooled as quickly as possible:▷At an external temperature of approx.
32 ℉/0 ℃.▷When the engine is running.
The air flow can be adjusted when the program
is active.
Automatic recirculated-air control/
recirculated-air mode
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.
Press the button repeatedly to select
an operating mode:
▷LEDs off: outside air flows in continuously.▷Left LED on, automatic recirculated-air con‐
trol: a sensor detects pollutants in the out‐
side air and controls the shut-off automati‐
cally.▷Right LED on, recirculated-air mode: the
supply of outside air into the vehicle is per‐
manently blocked.
If the windows are fogged over, switch off the
recirculated-air mode and press the AUTO but‐
ton on the driver's side to utilize the condensa‐
tion sensor. Make sure that air can flow onto the
windshield.
Continuous recirculated-air mode
The recirculated-air mode should not be
used for an extended period of time, as the air
quality inside the vehicle deteriorates steadily. ◀

able for your vehicle. Ask your service center for
suitable additives.Coolant level
Checking1.Let the engine cool.2.Turn the cap of the coolant reservoir slightly
counterclockwise to allow any excess pres‐
sure to dissipate, and then open it.3.The coolant level is correct if it lies between
the minimum and maximum marks in the
filler neck.4.If the coolant is low, slowly add coolant up to
the specified level; do not overfill.5.Turn the cap until there is an audible click.6.Have the cause of the coolant loss elimi‐
nated as soon as possible.
