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.

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.

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 ℃.Seite 167Climate controlControls167

▷When the engine is running or when elec‐
trical drive readiness is available.
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.

needed.
The system can be switched on and off di‐
rectly or by using two preset reel-on times. It
remains switched on for 30 minutes.

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.

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 216MobilityCoolant216
