Climate control systemThe vehicle is equipped with Electronic Climate Control (ECC) that cools, heats, dehumidifiesand filters the air in the passenger compartment.
4-zone climate system
4-zone system climate zones
The 4-zone climate system makes it possible to set the left- and right-side temperatures sepa-rately for the front and rears seats. All climate system settings are made from the center display and the buttons in the center con-sole. Settings for the rear seats can also bemade from the climate system panel on the rearside of the tunnel console.

Perceived temperature
The climate system regulates passenger com- partment temperature based on the perceivedtemperature, not on the actual one.
The selected passenger compartment tempera- ture is based on a physical perception relating tothe current ambient temperature, air flow, humid-ity, sunlight in the passenger compartment, etc. The system's sunlight sensor monitors the side of the car where sunlight is entering the passengercompartment. This means that the actual tem-perature may differ between the right and leftsides of the compartment, even if the tempera-ture setting is the same for both sides.

Climate system sensors The climate system's sensors help regulate the passenger compartment temperature, humiditylevel, etc.
Location of the sensors
Humidity sensor: in the rearview mirror con- sole.
Ambient temperature sensor: in the pas- senger's side door mirror.
Passenger compartment temperature sen- sor: near the center console buttons.
Sunlight sensor: on the upper side of the dashboard.
NOTE
Do not cover or block the sensors with cloth- ing or other objects.
On models equipped with the optional Interior Air Quality System, there is also an air quality sensorlocated at the climate system's air intake.

Parking climate (preconditioning)
The climate in the passenger compartment can be preconditioned and maintained, even whenthe vehicle is parked. For full functionality, the
vehicle's charging cable must be connected .
Parking climate/preconditioning and maintaining pas- senger compartment climate comfort is controlled from the Parking climate tab in the center display's Climate
view.

PreconditioningPreconditioning the vehicle before driving can help reduce wear and reduce energy consump-tion during a trip.
NOTE
Full preconditioning is only possible when the vehicle's charging cable is connected. In other cases, the passenger compartment can be cooled for 3 minutes in warm weather. This function is started from the
Parking
climate tab in the center display's Climate
view.
With the charging cable connected, precondition- ing can be started immediately or a timer functioncan start this procedure at a later time. This feature utilizes several of the vehicle's sys- tems:
• The High Voltage Coolant Heater (HVCH)warms the hybrid battery and passengercompartment in cold weather.
• In warm weather, the ventilation system willattempt to cool the passenger compartmentto the current ambient temperature.
• In warm weather, the air conditioning systemwill cool the passenger compartment to acomfortable temperature. •
The electrically heated steering wheel andseats can be activated.
• Heating for the windshield, tailgate windowand door mirrors can be activated.
If preconditioning is used in warm weather, a cer-tain amount of water may condense under thevehicle, which is normal. When preconditioning is used, this system will attempt to establish a comfortable temperature in the passenger compartment but not necessarily
the temperature currently set in the climate system .
Maintaining a comfortable passenger compartment climate
The climate in the passenger compartment can be maintained even when the vehicle is parkedand the engine is turned off (e.g., if anyoneintends to remain in the vehicle). This function can only be direct-started.This function utilizes several of the vehicle's sys- tems:
• Residual heat from the engine is used helpkeep the passenger compartment warm incool temperatures.
• In warm weather, the ventilation system willattempt to cool the passenger compartmentto the current ambient temperature.
This function will not be activated if the vehicle islocked from the outside in order to avoid using residual engine heat unnecessarily. This functionis primarily intended for use when the engine isnot running but someone remains in the vehicle.

Preconditioning timer
The timer can be set to start preconditioning at a predetermined time.
The timer can store up to 8 preset times for:
• A time on a particular date
• A time on one or more days of the week, with or without the repeat function.
NOTE
Full preconditioning is only possible when the vehicle's charging cable is connected. In other cases, the passenger compartment can be cooled for 3 minutes in warm weather. This function is started from the
