equipment
This chapter describes all standard, national
and special equipment available for the model
series. Therefore equipment which is not inj stalled in your vehicle, for example on account
of the selected optional equipment or the
country specification, may also be described
here. This also applies to safety-relevant funcj
tions and systems. Comply with the relevant
laws and regulations when using the correj
sponding functions and systems.Interior
air
quality
An emissions-tested interior and the installaj
tion of microfilters and a climate-control sysj tem with functions for controlling the temperajture, air flow and air recirculation haveimproved air quality inside the vehicle.
In addition there are other functions which dej
pend on the vehicle's equipment, for example microfilter/activated charcoal filter, automaticair conditioning with automatic air recirculationcontrol AUC, and independent ventilation.

Temperature
Principle
The automatic air conditioning adjusts to the set temperature as quickly as possible, using maximum cooling or heating power if necesjsary. The temperature is then maintained.
Adjusting Turn the wheel to select the dej
sired temperature.
Avoid switching between different temperature settings in rapid succession. The automatic airconditioning will otherwise not have sufficient
time to establish the temperature selected.
Cooling
function Principle
Interior air is cooled and dried, then reheated
to suit the temperature setting.
The interior can only be cooled when the enj gine is running.
Switching
on/off
Press the button.
The cooling function is switched on or
off.
Depending on weather conditions, the windj
screen and side windows may mist over for a short time when the engine is started.
The cooling function is switched on automatij
cally in the AUTO program.
When the automatic air conditioning is in operj
ation, condensation, see page 195, develops
which exits underneath the vehicle.
AUTO
program Principle
The air flow, air distribution and temperature are automatically regulated.
Switching
on/off Press the button.
Depending on the selected temperaj
ture and external influences, the air is directed
towards the windscreen, side windows, and
upper body, and into the footwell.
The cooling function, see page 172, is
switched on automatically in the AUTO proj
gram.
Recirculated-air
mode Principle
If the air outside the vehicle has an unpleasant
odour or contains pollutants, the supply to the
interior of the vehicle can be shut off. The air inside the vehicle is then recirculated.

air supply is permanently shut off.
The recirculated-air mode automatically
switches off after a given time depending on
the ambient conditions, to avoid condensation.

the air quality in the interior and condensation
on the windows increases.
In the event of condensation, switch off the rej

Principle
Automatic air recirculation control AUC dej
tects pollutants in the outside air. The supply
of outside air is shut off and the interior air is recirculated.
General
When the system is activated, a sensor detects
pollutants in the outside air and controls the shut-off automatically.
When the system is deactivated, outside air
flows into the interior continuously.
Continuous recirculated-air mode deteriorates
the air quality in the interior and condensation
on the windows increases.

the ambient air supply is permanently shut off.
The recirculated-air mode automatically
switches off at low outside temperatures after a given time, to avoid condensation.
If there is condensation on the window, switch
off recirculated-air mode and press the AUTO button to use the condensation sensor. Ensurethat air can flow towards the windscreen.

General
To be able to adjust the air flow manually, first switch off the AUTO program.

Independent
ventilation
Principle The independent ventilation system ventilatesthe passenger compartment and lowers its temperature where required.
General
The independent ventilation can be switched on and off via two preselected switch-on timesor directly. The system remains switched onfor 30 minutes.
The independent ventilation is operated using
iDrive.

state.'yDirect operation or preselected switch-on
time: does not depend on the outside temj

The vehicle battery is discharged when the
independent ventilation is switched on. As a result, the maximum activation time is rej
stricted to protect the battery. After the enj
gine is started or after driving a short disj tance, the system will be available again.'yEnsure that the data and time are set corjrectly in the vehicle.'yOpen the ventilation vents to allow the airto enter the passenger compartment.
