The rear automatic climate control is not op‐
erational if the automatic climate control is
switched off or if the function for defrosting or
defogging the windows is active.
AUTO program Press button.
Air flow, air distribution, and tempera‐
ture are controlled automatically:
Depending on the selected temperature, the
AUTO intensity, and outside influences, the air
is directed to the upper body and into the foot‐
well.
The cooling function is switched on automati‐
cally with the AUTO program.
Intensity of the AUTO program With the AUTO program activated, the auto‐
matic intensity control can be changed:
Press the left or right side of the but‐
ton: decrease or increase the inten‐
sity.
The selected intensity is shown on the display
of the automatic climate control.
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. The automatic climate con‐
trol will not have sufficient time to adjust the
set temperature.
Manual air distribution
The air distribution can be adjusted to individ‐
ual needs.
Press button repeatedly to select a
program:▷Upper body region.▷Upper body region and footwell.▷Footwell.
Air flow, manual
To manually adjust air flow turn off AUTO pro‐
gram first.
Press the left or right side of the but‐
ton: decrease or increase air flow.
The selected air flow is shown on the display of
the automatic climate control.
Switching the system on/off
Switch off Press and hold the left button.
Switching on Press any button except:
▷Left side of Air volume button.▷Seat heating.
Maximum cooling
Press button.
The system is set to the lowest tem‐
perature, maximum 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.
Air is cooled as quickly as possible:
▷At an external temperature of approx.
32 ℉/0 ℃.▷When the engine is running.Seite 165Climate controlControls165

Residual cooling
When the automatic climate control has re‐
duced the interior temperature, this tempera‐
ture can be maintained after the engine has
been switched off. This function can be acti‐
vated up to 15 minutes after the engine is
switched off and for a maximum period of 6 mi‐
nutes.
Functional requirement▷The high-voltage battery is sufficiently
charged.▷External temperature at least ap‐
prox. 59 ℉/15 ℃.

bution can be adjusted with the radio-ready
state switched on.
Switch off Press and hold the left button.
The symbol on the automatic climate Con‐
trol Display disappears.
Parked-car ventilation The conceptThe parked-car ventilation ventilates the vehi‐
cle interior and lowers its temperature, if
needed.
The system can be switched on and off di‐
rectly or by using two preset departure times.
The reel-on time is automatically determined
based on the temperature. The system
promptly switches on before the selected de‐
parture time.
Open the vents to allow air to flow out.
Functional requirement▷When the departure time is preselected:
depends on internal, external and set tem‐
perature.▷When operated directly and if there is no
parked-car heating: any external tempera‐
ture.

Auxiliary air conditioning
The concept Auxiliary air conditioning cools the heated ve‐
hicle interior immediately prior to driving off.
The automatic climate control lowers the inte‐
rior temperature with high cooling output.
The auxiliary air conditioning can be switched
on or off using the remote control.
The system is activated for approx. two mi‐
nutes.

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.
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 211CoolantMobility211
