Climate controlVehicle features and options
This 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.
Automatic climate controlHints 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 worsens.◀
Climate control functions in detail
Manual air distribution Press button repeatedly to select a
program:▷Upper body region.▷Upper body region and footwell.▷Footwell.▷Windows and footwell.▷Windows, upper body region, and footwell.▷Windows: driver's side only.▷Windows and upper body region.
If the windows are fogged over, press the
AUTO button on the driver's side to utilize the
condensation sensor.
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 li‐
dacity, and then keeps it constant.
Do not rapidly switch between different tem‐
perature settings. Otherwise, the automatic cli‐
mate control will not have sufficient time to ad‐
just the set temperature.
AUTO program Press button.
Air flow, air distribution and tempera‐
ture are controlled automatically.
Depending on the selected temperature,
AUTO intensity program and outside influen‐
ces, the air is directed to the windshield, side
windows, upper body, and into the footwell.
The cooling function, refer to page 158, is
switched on automatically with the AUTO pro‐
gram.
At the same time, a condensation sensor con‐
trols the program so as to prevent window
condensation as much as possible.
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.Seite 157Climate controlControls157

Air flow, manualTo 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.
The air flow of the automatic climate control
may be reduced automatically to save battery
power.
Defrosts windows and removes
condensation
Press button.
Ice and condensation are quickly re‐
moved from the windshield and the front side
windows.
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
reel on the cooling function or press the AUTO
button to utilize the condensation sensor.
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 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, reel off the re‐
circulated-air mode and press the AUTO but‐
ton on the driver's side to utilize the condensa‐
tion 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 worsens.◀
Cooling function
The car's interior can only be cooled with the
engine running.
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 180, devel‐
ops that exits underneath the vehicle.

Parked-car ventilation/
heating
The concept The parked-car ventilation ventilates the vehi‐
cle interior and lowers its temperature, if
needed.
The parked-car heating warms the vehicle in‐
terior, making snow and ice easier to remove.
With the ignition switched off, the air is auto‐
matically routed to the windshield, to the side
windows, and into the footwell.
The systems can be switched on and off di‐
rectly or by using two preset reel-on times.
They remain switched on for 30 minutes.
Operation takes place on the iDrive or the re‐ mote control.
Hints Parked-car heating in enclosed areas
Do not operate the parked-car heating in
enclosed areas, since breathing in harmful ex‐
haust fumes may lead to loss of consciousness
and death. The exhaust gases contain carbon
monoxide, an odorless and colorless but highly
toxic gas. Switch off the parked-car heating
when refueling.◀
Operation of the parked-car heating
When parked-car heating is in operation,
high temperatures can occur under the car
body. Before the parked-car heating is switched on, make sure that no flammable ma‐
terials, such as hay, leaves, grass, etc. are un‐
der the vehicle. Such contact could lead to a
fire, resulting in an increased risk of serious
personal injury as well as property damage.◀
At external temperatures below 32 ℉/0 ℃, wa‐
ter vapor occurs that emerges from below the
vehicle.
Functional requirements
Parked-car ventilation▷With the remote control or using the preset
reel-on time: external temperature above
approx. 59 ℉/15 ℃.▷When operated directly and if there is no
parked-car heating: any external tempera‐
ture.
Open the vents to allow air to flow out.
Parked-car heating
▷With the remote control or using the preset
reel-on time: external temperature below
approx. 59 ℉/15 ℃.▷Direct operation: any external temperature.▷The battery is sufficiently charged.▷The fuel tank is filled to above the reserve
range.
If the parked-car heating has not been used for
several months, it may be necessary to reel the
system on again after several minutes.
Switching on/off directly
