Air distribution – general
The incoming air is distributed through a number of different vents in the passenger compartment.
Air distribution is fully automatic in AUTO
mode (p. 134). If desired, air distribution can be controlled man- ually, see Air distribution – function (p. 136).

Electronic climate control (ECC)
ECC (Electronic Climate Control) helps maintain the selected temperature in the passenger com- partment and the temperature can be set sepa-rately on the driver's and passenger's sides.
The AUTO function (p. 134) automatically regu-lates the temperature, air conditioning, blowerspeed, recirculation and air distribution.

Heated seats
The front seat heating has three levels to increase comfort for the driver and passenger incold weather. The rear outboard seat heating has three levels to increase comfort for the passengers in coldweather.
Heated front seats *
The current seat temperature setting is shown in the center console display
Press the lower section of the button repeatedly until thedesired number of indicatorlights illuminate: Highest heat level – three indi- cator 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 automatically
This setting starts heating the driver's seat (at the highest level) automatically when the engine isstarted if the ambient temperature is belowapprox. 50° F (10° C). Activate/deactivate this function in the MY CAR

Temperature and blower control
When the vehicle is started, the most recent set- ting is resumed. The blower should always be activated to help avoid condensation and fogging on the win-dows.
Temperature controlThe temperatures on the driver and passenger sides can beset separately.
NOTE
Heating or cooling cannot be speeded up by selecting a higher/lower temperature thanthe actual temperature required.
Blower controlTurn the control clockwise to increase or counterclockwise todecrease the blower speed. If AUTO (p. 134) is selected,
blower speed will be regulated automatically and this will over-ride manual adjustment.
NOTE
If the blower is turned off completely, the air conditioning is disengaged, which may resultin fogging on the windows.

Air conditioning
The air conditioning function cools and dehu- midifies the air in the passenger compartment.
When the indicator light in the button is on, the air condition-ing is controlled automatically.This cools/heats and dehu-midifies the incoming air. Whenthe indicator light in the buttonis off, the air conditioning is
disengaged. Other functions are still controlledautomatically. When maximum defroster (p. 135)is selected, the air conditioning system is set formaximum blower speed and dehumidifies thecabin as quickly as possible.

NOTE
• Triangular areas at the far sides of the windshield are not heated electrically andwill take slightly longer to defrost/de-ice.
• The heated windshield may affect theperformance/range of e.g., transpondersused to automatically pay highway tolls orother communication equipment.
The following occurs when the defroster/wind- shield heating functions have been activated:
• Blower speed increases automatically andthe air conditioning (p. 135) will switch on (ifnot already on and if the passenger compart-ment blower is not turned off) to dehumidifythe air in the passenger compartment. Airconditioning can be switched off by pressing the
AC button.
• Recirculation (p. 137) will not function while defrost is engaged.
The climate system will return to its previous set-tings when the defroster/windshield heatingfunction is switched off. See also Heated windshield *, rear window and
door mirror defrosters (p. 108) for additional information.

Starting the engineThe maximum range for ERS is approximately 100 ft (30 meters) if the view of the vehicle is unobstructed. The vehicle must also be
locked. To start the engine:
1. Press the lock button (1 ) briefly.
2. Immediately press the approach lighting but- ton (2) for approximately 2 seconds.
If the requirements for ERS have been met, the following will occur: 1. The turn signals will flash several times.
2. The engine will start.
3. The turn signals will illuminate for 3 seconds
to indicate that the engine has started.
After the engine has started, the vehicle remains locked but the alarm is disarmed.
Active functions
When the engine is started with ERS, the follow- ing functions are activated: • The climate control system
• The infotainment system.
• Approach lighting

Start/Stop – Auto-stop exceptions
In certain situations or conditions, the engine may not auto-stop when the vehicle comes to a
standstill, such as if:
Condition/situation The vehicle's speed has not reached a speed of approx. 6 mph (10 km/h) after the mostrecent auto-start or after the driver has startedthe engine. The driver unbuckles his/her seat belt.The main battery's charge is below the mini- mum level. The engine has not reached its normal operat- ing temperature. The ambient temperature is below approx. 25°F (-4°C) or above approx. 85°F (30°C). The windshield's heating function * is activated.
The climate system cannot keep the desired settings in the passenger compartment; theblower will operate at high speed. The vehicle is backing up.The main battery's temperature is below freez- ing or too high. The driver is turning the steering wheel hard.
Condition/situation The road's incline is very steep. A trailer's electrical system is connected to the vehicle. The hood has been opened A
.
The transmission has not reached its normal operating temperature. Atmospheric pressure is below a level equiva- lent to an altitude of approx. 4,900–8,200 ft
(1500–2500 m) above sea level. The actualpressure is also affected by current weatherconditions. The Adaptive Cruise Control's * Queue Assist
