Recirculation/air quality system

Recirculation

This function can be used to

shut out exhaust fumes,

smoke, etc from the passen-

ger compartment. The air in

the passenger compartment

is then recirculated, i.e., no air

from outside the car is taken

into the car when this function is activated. The

indicator light in the button will illuminate when

recirculation is selected.

If the air in the car recirculates for too long,

there is a risk of condensation forming on the

insides of the windows, especially in winter.

Timer

The timer function minimizes the risk of fog-

ging, or stale air when the recirculation function

is selected by automatically switching off the

function after a certain length of time, depend-

ing on the ambient temperature. Activate/

deactivate the function under Climate

settings

Recirculation time. For a

description of the menu system, see

page 124.

NOTE

When Defroster is selected, recirculation is

always deactivated.

Interior Air Quality System–IAQS*

This system consists of a mul-

tifilter and an air quality sen-

sor. The filter helps remove

gases and particles from the

incoming air, thereby reduc-

ing the amounts of odors and

contaminants entering the

vehicle. The air quality sensor detects

increased levels of contaminants in the outside

air. When the air quality sensor detects conta-

minated outside air, the air intake closes and

the air inside the passenger compartment is

recirculated, i.e., no outside air enters the vehi-

cle. The filter also cleans recirculated passen-

ger compartment air. When the AUTO button

is depressed the air quality sensor is always

engaged.

Activating the air quality sensor

Switch between the three

functions by pressing the but-

ton repeatedly.

•

The left orange light comes on – the air

quality sensor is disengaged.

•

The center green light comes on – recircu-

lation not engaged, providing it is not

required for cooling in hot weather.

•

The right orange light comes on – recircu-

lation is engaged.

NOTE

•

The air quality sensor should always be

engaged in order to obtain the best air

in the passenger compartment.

•

Recirculation is limited in cold weather

to avoid fogging.

•

If the insides of the windows start fog-

ging, disengage the air quality sensor.

Use the defroster function to increase

airflow to the front, side, and rear win-

dows.
