Vehicle features and

options

Interior air quality

The air quality inside the vehicle is improved by

an emissions-tested interior, a microfilter, and a

climate-control system for regulating tempera‐

ture, air flow, and recirculated-air mode.

This chapter describes all standard, country-spe‐

cific and optional features offered with the series.

It also describes features that are not necessarily

available in your vehicle, e. g., due to the selected

options or country versions. This also applies to

safety-related functions and systems. When us‐

ing these functions and systems, the applicable

laws and regulations must be observed.

In addition there are other functions which de‐

pend on the vehicle's equipment, for instance

microfilter/activated-charcoal filter, automatic cli‐

mate control with automatic recirculated-air con‐

trol AUC, and parked-car ventilation.

Switching the system on/off

Press button.

Switching on

The LED is illuminated with air condi‐

tioning switched on.

Press any button except for the following:

▷ Rear window defroster.

▷ Seat heating.

Depending on the weather, the windshield and

side windows may fog up briefly when the en‐

gine is started.

Switching off

The air conditioning is switched on automatically

with the AUTO program.

Press the left button for the minimum

speed.

When using the automatic climate control, con‐

densation water, refer to page 229, develops

and drains underneath the vehicle. This is nor‐

mal.

Temperature

Concept

AUTO program

The automatic climate control achieves the set

temperature as quickly as possible, if necessary

by using the maximum cooling or heating power,

and then keeps it constant.

Concept

Air flow, air distribution and temperature are con‐

trolled automatically.

Settings

Switching on/off

Turn the ring to set the desired

temperature.

Press button.

The LED is illuminated with the AUTO

program switched on.

Depending on the selected temperature and out‐

side influences, the air is directed to the wind‐

shield, side windows, upper body, and into the

floor area.

Do not rapidly switch between different tempera‐

ture settings. Otherwise, the automatic climate

control will not have sufficient time to adjust the

set temperature.

The air conditioning, refer to page 201, is

switched on automatically with the AUTO pro‐

gram.

Air conditioning

Concept

The air in the car's interior will be cooled and de‐

humidified and, depending on the temperature

setting, warmed again.

Climate control

CONTROLS

Recirculated-air mode

Controlling the air distribution

manually

Concept

You may react to unpleasant odors or pollutants

in the immediate environment by temporarily

suspending the supply of outside air. The system

then recirculates the air flow within the vehicle.

The air distribution for climate control can be ad‐

justed manually.

Operation

Turn the wheel to select the de‐

sired program or the desired in‐

termediate setting.

Press button repeatedly to select an op‐

erating mode:

▷ LED off: outside air flows in continuously.

▷ LED on, recirculated-air mode: the supply of

outside air into the vehicle is permanently

blocked.

▷

Windows.

Upper body region.

Windows, upper body region, and floor

area.

To prevent window fogging, recirculated-air

mode switches off automatically after a certain

amount of time, depending on the environmental

conditions.

▷

Floor area.

Defrosting windows and removing

condensation

Make the following settings to defrost the win‐

dows and remove condensation:

With constant recirculated-air mode, the air qual‐

ity in the car's interior deteriorates and the fog‐

ging of the windows increases.

If the windows fog over, switch off recirculated-

air mode and increase the air flow, if needed.

▷ Direct the air distribution onto the windows.

▷ Increasing the air flow.

Controlling the air flow manually

▷ Increase the temperature.

▷ Switch on the air conditioning if needed.

Concept

The air flow for climate control can be adjusted

manually.

Rear window defroster

Press button. The LED lights up.

Operation

The rear window defroster switches off

automatically after a certain period of time.

Press the left or right side of the button:

decrease or increase air flow.

Microfilter

In external and recirculated-air mode the microfil‐

ter filters dust and pollen from the air.

The air flow from the air conditioner may be re‐

duced automatically to save battery power.

Have this filter changed during vehicle mainte‐

nance, refer to page 274.

Maximum cooling

Concept

Settings

The system is set to the lowest temperature, op‐

timum air flow and recirculated-air mode.

Turn the ring to set the desired

temperature.

General information

The function is available above an external tem‐

perature of approx. 32 ℉/0 ℃ And with the en‐

gine running.

The automatic climate control reaches this tem‐

perature as quickly as possible, if needed, by in‐

creasing the cooling or heating output, and then

keeps it constant.

Switching on/off

Press button.

Do not rapidly switch between different tempera‐

ture settings. Otherwise, the automatic climate

control will not have sufficient time to adjust the

set temperature.

The LED is illuminated with the system

switched on.

Air flows out of the vents to the upper body re‐

gion. The vents need to be open for this.

Air conditioning

The air flow can be adjusted with the air flow ac‐

tive.

Concept

The air in the car's interior will be cooled and de‐

humidified and, depending on the temperature

setting, warmed again.

Depending on the selected temperature, the in‐

tensity of the AUTO program, and outside influ‐

ences, the air is directed to the windshield, side

windows, upper body, and into the floor area.

The air conditioning is switched on automatically

with the AUTO program.

The air conditioning, refer to page 204, is

switched on automatically with the AUTO pro‐

gram.

When using the automatic climate control, con‐

densation water, refer to page 229, develops

and drains underneath the vehicle. This is nor‐

mal.

At the same time, a condensation sensor con‐

trols the program so as to prevent window con‐

densation as much as possible.

Climate control

CONTROLS

In the AUTO program, the air flow may be re‐

duced during a phone call on the hands-free sys‐

tem.

Recirculated-air mode switches off automatically

at low external temperatures after a certain

amount of time in order to avoid window fogging.

If the windows are fogged over, switch off the re‐

circulated-air mode and press the AUTO button

to utilize the condensation sensor. Make sure

that air can flow to the windshield.

Intensity

With the AUTO program switched on, the inten‐

sity can be set. This changes the automatic con‐

trol for the air flow and air distribution.

Controlling the air flow manually

Press the left or right side of the button:

decrease or increase intensity.

Concept

The selected intensity is shown on the display of

the automatic climate control.

The air flow for climate control can be adjusted

manually.

Automatic recirculated-air control/

recirculated-air mode

General information

To manually adjust air flow switch off AUTO pro‐

gram first.

Concept

The automatic recirculated-air control AUC rec‐

ognizes odors or pollutants in the outside air.

The outside air supply is shut off and the interior

air is recirculated.

Operation

Press the left or right side of the button:

decrease or increase air flow.

The selected air flow is shown on the display of

the automatic climate control.

General information

If the system is activated, a sensor detects pollu‐

tants in the outside air and controls the shut-off

automatically.

The air flow of the automatic climate control may

be reduced automatically to save battery power.

If the system is deactivated, outside air continu‐

ously flows into the car's interior.

Controlling the air distribution

manually

With constant recirculated-air mode, the air qual‐

ity in the car's interior deteriorates and the fog‐

ging of the windows increases.

Concept

The air distribution for climate control can be ad‐

justed manually.

tive.

Toward blue: colder.

Toward red: warmer.

If the windows are fogged over, you can also

switch on the air conditioning or press the AUTO

button to utilize the condensation sensor.

This does not change the set interior temper‐

ature for the driver and front passenger.

Microfilter/activated-charcoal filter

In external and recirculated-air mode the microfil‐

ter/activated charcoal filter filters dust, pollen, and

gaseous pollutants out of the air.

Have this filter changed during vehicle mainte‐
