Maximum coolingPress the button.
The system is set to the lowest tem‐
perature, maximum air flow and air circulation
mode.
Air flows out of the vents for the upper body
region. 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 or when elec‐
trical drive readiness is indicated.
The air volume can be adjusted when the pro‐
gram 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
control: a sensor detects pollutants in the
outside air and controls the shutoff auto‐
matically.▷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
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 stead‐
ily.◀
Cooling function The passenger compartment can be cooled
with the engine running or switched off.
Press the button.
The air is cooled and dehumidified
and – depending on the temperature setting –
warmed again.
Depending on the weather, the windshield may
fog up briefly when the engine is started.
The cooling function is switched on automati‐
cally with the AUTO program.

The efficiency of the driving style is shown by
the color of the bar:
▷Blue display: efficient driving style as long
as the mark moves within the blue range.▷Gray display: adjust driving style, e. g. by
backing off the accelerator pedal.
The display switches to blue as soon as all
conditions for fuel-economy-optimized driving
are met.
ECO PRO Tip - driving instruction The arrow indicates that the
driving style can be adjusted to
be more fuel efficient by backing off the accelerator for instance.

CoolantVehicle equipmentAll standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
General information Danger of burns from hot engine
Do not open the cooling system while
the engine is hot; otherwise, escaping 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 your vehicle. Ask your service cen‐
ter for suitable additives.
Coolant level
If there is no Min. and Max. mark in the filler
neck of the coolant reservoir, have the coolant
level checked if necessary by your service cen‐
ter and add coolant as needed.
Note Depending on the engine installation, the cool‐
ant reservoir may be located on the opposite side of the engine compartment.Checking1.Let the engine cool.2.Turn the cap of the coolant reservoir
slightly counterclockwise to allow any ex‐
cess pressure to dissipate, and then open
it.3.The coolant level is correct if it lies be‐
tween 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.
The arrows on the coolant reservoir and
the cap must point towards one another.6.Have the cause of the coolant loss elimi‐
nated as soon as possible.Seite 210MobilityCoolant210
