Interior Air Quality System* (p. 200)
Perceived temperature
The climate control system regulates the climatein the passenger compartment based on per-ceived temperature, not actual temperature.
The selected passenger compartment tempera-ture is based on the physical perception of thecurrent ambient temperature, airflow speed,humidity, sunlight in the passenger compartment,etc.
The system has a sunlight sensor that detectswhich side of the vehicle the sunlight is shiningon and adjusts the temperature accordingly. Thismeans that the temperature of the air coming outof the vents may be different for the left and rightsides, even if the temperature setting is the samefor both sides.

Climate control system voice
commands1
Voice commands can be used for the climatecontrol system to e.g. change temperature, acti-vate seat heating* or change blower speed.
Tap and say one of the following commands:
"Climate" - starts a command dialog for cli-mate controls and provides examples ofcommands that can be used.
"Set temperature to X degrees" - setsdesired temperature.
"Raise temperature"/"Lowertemperature" - raises/lowers the set tem-perature.
"Sync temperature" - synchronizes thetemperature for all climate zones in the vehi-cle with the temperature set for the driver'sside.
"Air on feet"/"Air on body" - opens thedesired air vent.
"Air on feet off"/"Air on body off" - closesthe desired air vent.
"Set fan to max"/"Turn off fan" - changesblower speed to Max/Off.
"Raise fan speed"/"Lower fan speed" -raises/lowers the set blower speed.

Interior Air Quality System*
Interior Air Quality System (IAQS) is a fully auto-matic air quality system that removes gases andparticles to reduce odors and contaminants inthe passenger compartment.
IAQS is part of the Clean Zone Interior Package(CZIP) and removes air contaminants such asparticles, hydrocarbons, nitric oxides and ground-level ozone.
If the system's air quality sensors detect contami-nants in the outside air, the air intake closes andair recirculation is activated.

NOTE
To ensure optimal air quality in the passengercompartment, the air quality sensor shouldalways be engaged.
Recirculation is limited in cold weather to pre-vent fogging.
In the event of fogging, use the defrosterfunctions for the windshield, side windowsand rear window.

Opening and closing the trunk lid
with foot movement*
To make it easier to operate the trunk lid whenyour hands are full, it can be opened and closedby moving your foot in a forward kicking motionunder the rear bumper.
The sensor is located to the left of center under the rearbumper.
One of the vehicle's remote keys must be withinrange behind the vehicle (approx. 1 meter (3feet)) for opening and closing to be possible. Thisapplies even if the vehicle is unlocked in order toprevent the trunk lid from inadvertently openinge.g. at a car wash.
Foot movement operation
Kicking motion within the sensor's activation area.
–Make one slow forward kicking motion withyour foot under the left section of the rearbumper. Take a step back. Do not touch thebumper.
> A brief audible signal will sound whenopening or closing is activated - the trunklid will open/close.
If the trunk lid is open, it will always
close19 when the foot motion sensor isactivated.
If several opening attempts have been madewithout the remote key in range behind the vehi-cle, foot movement operation will not be availablefor a short period of time.
