Pressing this button cancels
automatic air conditioning and
turns off the air conditioner.
Press AUTO to return to automatic
operation and the air conditioner
runs automatically as needed.
When the indicator light is on, the
air conditioner runs automatically
to cool the air inside the vehicle or
to dry the air needed to defog the
windshield faster.
>(Recirculation):Press to
alternate between recirculating
air inside the vehicle or pulling in
outside air. When the indicator light
is on, air is being recirculated inside
the vehicle. This helps to quickly
cool the air inside the vehicle or
prevent outside air and odors from
entering.
Pressing this button cancels
automatic recirculation. Press AUTO
to return to automatic operation and
recirculation runs automatically as
needed.
Rear Window Defogger
=(Rear Window Defogger):
Press to turn the rear window
defogger on or off.
The rear window defogger
turns off automatically after
about 10 minutes. If turned on
again it runs for about five minutes
before turning off. The defogger
can also be turned off by turning
the ignition to ACC/ACCESSORY
or LOCK/OFF.
The rear window defogger can
be set to automatic operation.
See “Climate and Air Quality”
under Vehicle Personalization on
page 5‑39. When auto rear defog is
selected, the rear window defogger
turns on automatically when the
interior temperature is cold and
the outside temperature is about
4°C (40°F) and below. The auto
rear defogger turns off automatically
after about 10 minutes, or after
five minutes if the outside
temperature is not as cold. For vehicles with heated outside
rearview mirrors, they turn on when
the rear window defogger button
is on and help to clear fog or frost
from the surface of the mirror.
See
Heated Mirrors on page 2‑17.
Notice: Do not try to clear frost
or other material from the inside
of the front windshield and rear
window with a razor blade or
anything else that is sharp. This
may damage the rear window
defogger grid and affect your
radio's ability to pick up stations
clearly. The repairs wouldn't be
covered by your warranty.
Remote Start Climate Control
Operation: For vehicles with the
remote vehicle start feature, the
climate control system may run
when the vehicle is started remotely.
The system uses the driver's
previous settings to heat or cool the
inside of the vehicle. See Remote
Vehicle Start on page 2‑8.

Ignition Positions
(Keyless Access)
The vehicle has an electronic
keyless ignition with push‐button
start.
Pressing the button cycles it through
three modes, ACC/ACCESSORY,
ON/RUN/START, and Stopping the
Engine/OFF.
The transmitter must be in the
vehicle for the system to operate.
If the push-button start is not
working, the vehicle may be neara strong radio antenna signal
causing interference to the keyless
access system. See
Remote
Keyless Entry (RKE) System
Operation on page 2‑4 for more
information.
To shift out of P (Park), the vehicle
must be in ACC/ACCESSORY or
ON/RUN and the brake pedal must
be applied.
Stopping the Engine/OFF
(No LED Lights): When the
vehicle is stopped, press the
engine START/STOP button
once to turn the engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory
Power (RAP) on page 9‑24 for
more information.
If the vehicle is not in P (Park),
the ignition will return to ACC/
ACCESSORY and display the
message SHIFT TO PARK in the
Driver Information Center (DIC). See
Transmission Messages on
page 5‑38 for more information.
When the vehicle is shifted into
P (Park), the ignition system will
switch to OFF.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
In an emergency, if the vehicle must
be shut off while driving:
1. Brake using a firm and steady pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to
a safe location.

Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to
a receiver located in the vehicle.
Each tire, including the spare
(if provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on
the vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low tirepressure telltale when one or
more of your tires is significantly
under‐inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them
to the proper pressure. Driving on
a significantly under‐inflated tire
causes the tire to overheat and can
lead to tire failure. Under‐inflation
also reduces fuel efficiency and
tire tread life, and may affect the
vehicle's handling and stopping
ability.
Please note that the TPMS is
not a substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct
tire pressure, even if under‐inflation
has not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the
system is not operating properly.The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start‐ups as
long as the malfunction exists.
When the malfunction indicator
is illuminated, the system may
not be able to detect or signal low
tire pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow
the TPMS to continue to function
properly.
See
Tire Pressure Monitor
Operation on page 10‑57 for
additional information.
