Ice and condensation are quickly removed
from the windshield and the front side win‐
dows.
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.
Maximum cooling Press button.
The system is set to the lowest tem‐
perature, optimum air flow and air circulation 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 or when electrical drive readi‐ ness is indicated is indicated.
Adjust air flow with the program active.
Automatic recirculated-air control/
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:▷LEDs off: outside air flows in continuously.▷Left LED on, automatic recirculated-air
control: a sensor detects pollutants in the
outside air and shuts off automatically.▷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
button on the driver's side to utilize the con‐
densation sensor. Make sure that air can flow
to the windshield.
Sufficient ventilation
When remaining in the vehicle for an ex‐
tended period of time, ensure sufficient exter‐
nal ventilation. Do not continuously use recir‐
culated-air mode; otherwise the air quality in
the interior continuously deteriorates and win‐
dow condensation increases.◀
Cooling function The car's interior can be cooled with the en‐
gine running or switched off.
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 cooling function is switched on automati‐
cally with the AUTO program.
When using the automatic climate control,
condensation water, refer to page 192, devel‐
ops that exits underneath the vehicle.
Rear window defroster Press button.
The rear window defroster switches
off automatically after a certain period of time.

side for temperature, air flow, air distri‐
bution, and AUTO program are transferred to the front passenger side and to the left and

CoolantVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Hints Danger of burns from hot engine
Do not open the cooling system while
the engine is hot; otherwise, esliding coolant
may cause burns.◀
Suitable additives
Only use suitable additives; otherwise,
engine damage may occur. The additives are
harmful to your health.◀
Coolant consists of water and additives.
Not all commercially available additives are
suitable for the vehicle. Information about the
suitable additives are available from the service
center.
Coolant level
General information
If there is no Min. and Max. mark in the filler
neck of the coolant reservoir, have the coolant
level checked if needed by your service center
and add coolant as needed.
Depending on the engine installation, the cool‐
ant reservoir is located on the right side or the
left side of the engine compartment.Checking1.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.Open the coolant reservoir lid.4.The coolant level is correct if it lies be‐
tween the minimum and maximum marks
in the filler neck.Seite 221CoolantMobility221
