Heated seats
The front seat heating has three levels to increase comfort for the driver and passengerin cold weather. The rear outboard seat heating has three lev- els to increase comfort for the passengers incold weather.
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. 50° F (10° C). Activate/deactivate this function in the MY CAR menu system, under

Temperature and blower control
When the vehicle is started, the most recent setting is resumed. The blower should always be activated to help avoid condensation and fogging on thewindows.
Temperature controlThe temperatures on thedriver and passenger sidescan be set separately.
NOTE
Heating or cooling cannot be speeded up by selecting a higher/lower temperaturethan the actual temperature required.
Blower controlTurn the control clockwise to increase or counterclockwiseto decrease the blowerspeed. If AUTO (p. 131) is
selected, blower speed willbe regulated automaticallyand this will override manual
adjustment.
NOTE
If the blower is turned off completely, the air conditioning is disengaged, which mayresult in fogging on the windows.

Air conditioning
The air conditioning function cools and dehu- midifies the air in the passenger compart-ment.
When the indicator light inthe 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
air conditioning is disengaged. Other func-tions are still controlled automatically. Whenmaximum defroster (p. 132) is selected, theair conditioning system is set for maximumblower speed and dehumidifies the cabin asquickly as possible.

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 (p. 132) willswitch on (if not already on and if the pas-senger compartment blower is not turnedoff) to dehumidify the air in the passengercompartment. Air conditioning can beswitched off by pressing the
AC button.
• Recirculation (p. 134) will not functionwhile defrost is engaged.
The climate system will return to its previous
settings when the defroster/windshield heat- ing function is switched off. See also Heated windshield*, rear window and door mirror defrosters (p. 104) for addi-tional information.

Air distribution – recirculation
Recirculation can be used to shut out exhaust fumes, smoke, etc., from the passenger com-partment.
The air in the passengercompartment is then recircu-lated, i.e., no air from outsidethe car is taken into the carwhen this function is acti-vated. The indicator light inthe 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 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

– introduction (p. 76) for a description of the menu system.
NOTE
When Defroster is selected, recirculation is always deactivated.
