Heated Seats — If Equipped
On some models, the front and rear seats may be equipped
with heaters located in the seat cushions and seat backs.
WARNING!
•Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion or other physical condition must exercise care
when using the seat heater. It may cause burns even
at low temperatures, especially if used for long
periods of time.
• Do not place anything on the seat or seatback that
insulates against heat, such as a blanket or cushion.
This may cause the seat heater to overheat. Sitting in
a seat that has been overheated could cause serious
burns due to the increased surface temperature of the
seat.
Front Heated Seats
The front heated seats control buttons are located on the
center instrument panel below the climate controls.
If your vehicle is equipped with a touchscreen, the front
heated seats control buttons are also located within the
climate or controls screen of the touchscreen.
• Press the heated seat button
once to turn the HI
setting on.
• Press the heated seat buttona second time to turn
the LO setting on.
• Press the heated seat buttona third time to turn the
heating elements off.
When the HI-level setting is selected, the heater will
provide a boosted heat level during the first four minutes
of operation. Then, the heat output will drop to the normal
HI-level. If the HI-level setting is selected, the system will
automatically switch to LO-level after approximately 60
minutes of continuous operation. At that time, the display
will change from HI to LO, indicating the change. The
LO-level setting will turn off automatically after approxi-
mately 45 minutes.

provides increased forward lighting at night by automat-
ing high beam control through the use of a digital camera
mounted on the inside rearview mirror. This camera de-
tects vehicle specific light and automatically switches from
high beams to low beams until the approaching vehicle is
out of view.

on or off using the instrument cluster display. Refer to
“Instrument Cluster Display” in “Understanding Your
Instrument Panel” for further information.
• Broken, muddy, or obstructed headlights and taillights
of vehicles in the field of view will cause headlights to
remain on longer (closer to the vehicle). Also, dirt, film, and other obstructions on the windshield or camera lens
will cause the system to function improperly.
• To opt out of the Advanced Auto High-Beam Sensitivity
Control (default) and enter Reduced High-Beam Sensi-
tivity Control (not recommended), toggle the high beam
lever six full on/off cycles within 10 seconds of ignition
ON. System will return to default setting upon ignition
off.
