Overview  
This chapter describes all standard, country-spe‐  
cific and optional features offered with the series.  
It also describes features and functions 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 sys‐  
tems. When using these functions and systems,  
the applicable laws and regulations must be ob‐  
served.

5. "Driver"  
The automatic recirculated-air control recognizes  
pollutants in the outside air. The outside air sup‐  
ply is shut off and the interior air is recirculated.  
6. "Automatic"  
General information  
Depending on the selected settings and outside  
influences, the air is directed to the windshield,  
side windows, upper body, and into the floor  
area.  
If the system is activated, a sensor detects pollu‐  
tants in the outside air and controls the shut-off  
automatically.  
If the system is deactivated, outside air continu‐  
ously flows into the car's interior.  
Point the side air vents toward the side windows.  
The cooling function is switched on with the  
AUTO program.  
With constant air recirculation mode, the air qual‐  
ity in the car's interior deteriorates and window  
fogging increases.  
At the same time, a condensation sensor con‐  
trols the program so as to prevent window con‐  
densation as much as possible.  
If there is window condensation, switch off recir‐  
culated-air mode or defog the windows.  
The AUTO program is switched off automati‐  
cally, when manual air distribution is set.

system switched on.  
Setting the ventilation  
General information  
Open the air vents and position them to ensure  
effective climate control.  
If there is window condensation, switch on the  
AUTO program or the air conditioning to utilize  
the condensation sensor. Make sure that air can  
flow to the windshield.  
Rear window defroster  
Principle  
Ice and condensation are removed from the rear  
window quickly.  
Direct ventilation  
The air flow is directed towards the passengers.  
The air flow heats or cools noticeably, depending  
on the adjusted temperature.  
Indirect ventilation  
Functional requirement  
The air flow is not directed towards the passen‐  
gers. The vehicle interior is warmed or cooled in‐  
directly, depending on the set temperature.  
The function is operational when the drive-ready  
state is switched on.  
Switching rear window defroster

DANGER  
To switch on the parked-car ventilation automati‐  
cally at the departure time, the departure time  
must be activated first.  
If the exhaust pipe is blocked or ventilation is in‐  
sufficient, harmful exhaust gases can pollute  
the area in and around the vehicle or enter into  
the vehicle. The exhaust gases contain pollu‐  
tants which are colorless and odorless. In en‐  
closed areas or areas with insufficient ventila‐  
tion, exhaust gases can also accumulate  
Via iDrive

outside of the vehicle. There is danger to life.  
Keep the exhaust pipe free and ensure suffi‐  
cient ventilation. Do not switch on stationary cli‐

sufficient ventilation, e.g. in enclosed garages.

Warning  
When stationary climate control is in operation,  
high temperatures can occur underneath the  
body, for instance caused by the exhaust gas  
system. If combustible materials, such as  
leaves or grass, come in contact with hot parts  
of the exhaust gas system, these materials can  
ignite. There is a risk of fire. Make sure that no  
combustible materials can come in contact with  
hot vehicle parts during stationary climate con‐  
trol operation, e.g. leaves, grass, gas, gasoline,  
oil or other combustible objects.
