The ventilation can be used at the same time as seat heating. The ventilation system can be activated when the engine is running. There are three comfortlevels that produce different cooling anddehumidifying effects:
• Level three: press the button once for maximum output – three indicator lightscome on.
• Level two: press the button twice for alower output – two indicator lights comeon.
• Level one: press the button three timesfor the lowest output – one indicator lightcomes on.
• Press the button a fourth time to switchoff the function – the indicator light will goout.
Heated front seats*
The current seat temperature setting is shown in the center console display
Press the lower section of the button repeatedly untilthe desired number of indi-cator lights illuminate: Highest heat level – three indicator lights.
Medium heat level – two indicator lights. Lowest heat level – one indicator light.If no indicator lights are illuminated, the seat heating is switched off.
Seat heating will automatically switch off when the engine is switched off.
Starting the seat heating automaticallyThis setting starts heating the driver's seat (at the highest level) automatically when theengine is started if the ambient temperature isbelow approx. 45° F (7° C). Activate/deactivate this function in the MY CAR menu system, under

Blower controlTurn the control clockwise to increase or counterclockwiseto decrease the blowerspeed. If AUTO is selected,
blower speed will be regula-ted automatically and thiswill override manual adjust-
ment.
NOTE
If the blower is turned off completely, the air conditioning is disengaged, which mayresult in fogging on the windows.

NOTE
Selecting the lowest blower speed may increases the risk of fog forming on thewindows.
Temperature controlThe temperatures on the driver and passenger sidescan be set separately. Whenthe vehicle is started, themost recent setting isresumed.
NOTE
Heating or cooling cannot be speeded up by selecting a higher/lower temperaturethan the actual temperature required.
A/C – ON/OFFWhen the indicator light in the button is on, the air con-ditioning is controlled auto-matically. This cools/heatsand dehumidifies the incom-ing air. When the indicatorlight in the button is off, the

• Press the button twice to start both the defroster and the windshield heating.Symbols (1) and (2) will illuminate in thecenter console display.
• If these features are on, press the buttonto switch them off. The symbols will nolonger be displayed.NOTE
•Triangular areas at the far sides of the windshield are not heated electricallyand will take slightly longer todefrost/de-ice.
• The heated windshield may affect theperformance/range of e.g., transpond-ers used to automatically pay highwaytolls or other communication equip-ment.
The following occurs when the defroster/ windshield heating functions have been acti-vated: •
Blower speed increases automatically and the air conditioning will switch on (ifnot already on and if the passenger com-partment blower is not turned off) todehumidify the air in the passenger com-partment. Air conditioning can beswitched off by pressing the
AC button.
• Recirculation will not function whiledefrost is engaged.
The climate system will return to its previous settings when the defroster/windshield heat-ing function is switched off. See also page 107 for additional information.
Recirculation/air quality system
RecirculationThis function can be used to shut out exhaust fumes,smoke, etc., from the pas-senger compartment. The airin the passenger compart-ment is then recirculated,i.e., no air from outside the
car is taken into the car when this function isactivated. The indicator light in the button willilluminate when recirculation is selected. If the air in the car recirculates for too long, there is a risk of condensation forming on theinsides of the windows, especially in winter.
TimerThe timer function minimizes the risk of fog- ging, or stale air when the recirculation func-tion is selected by automatically switching offthe function after a certain length of time,depending on the ambient temperature. Acti-vate/deactivate the function under

Recirculation timer. See page
201 for a description of the menu system.
NOTE
When Defroster is selected, recirculation is always deactivated.

Interior Air Quality System–IAQS*This system consists of a multifilter and an air quality sensor. The filter helps remove gasesand particles from the incoming air, therebyreducing the amounts of odors and contami-nants entering the vehicle. The air quality sen-sor detects increased levels of contaminantsin the outside air. When the air quality sensordetects contaminated outside air, the airintake closes and the air inside the passenger compartment is recirculated, i.e., no outsideair enters the vehicle. The filter also cleansrecirculated passenger compartment air.When the
AUTO button is depressed the air
quality sensor is always engaged. Activate or deactivate this function in
Climate
settings
Interior air quality system.
NOTE
• The air quality sensor should always be engaged in order to obtain the bestair in the passenger compartment.
• Recirculation is limited in cold weatherto avoid fogging.
• If the insides of the windows start fog-ging, disengage the air quality sensor.Use the defroster function to increaseairflow to the front, side, and rear win-dows.
