odors from entering your vehicle.
Note: Recirculated air may turn off, or
prevent you from switching on, in all air flow
modes except MAX A/C to reduce the risk
of fogging. Recirculation may also turn on
and off in various air distribution control
combinations during hot weather to improve
cooling efficiency.

and Off Touch the button to cycle
through the various ventilated
seat settings.
Accessing Rear Climate Controls Touch the button to access
additional controls for the rear
climate system.

PHONE WARNING: Driving while distracted
can result in loss of vehicle control, crash
and injury. We strongly recommend that
you use extreme caution when using any
device that may take your focus off the
road. Your primary responsibility is the
safe operation of your vehicle. We
recommend against the use of any
hand-held device while driving and
encourage the use of voice-operated
systems when possible. Make sure you
are aware of all applicable local laws
that may affect the use of electronic
