Keys, Doors and Windows 1-3
Remote Keyless Entry
(RKE) System
SeeRadio Frequency Statementon
page 12‑16for information
regarding Part 15 of the Federal
Communications Commission (FCC)
Rules and RSS-210/211 of Industry
Canada.
Changes or modifications to this
system by other than an authorized
service facility could void
authorization to use this equipment.
If there is a decrease in the RKE
operating range:
.Check the distance. The
transmitter may be too far from
the vehicle.
.Check the location. Other
vehicles or objects may be
blocking the signal.
.Check the transmitter's battery.
See “Battery Replacement” later
in this section.
.If the transmitter is still not
working correctly, see your
dealer/retailer or a qualified
technician for service.
Remote Keyless Entry
(RKE) System Operation
The Remote Keyless Entry (RKE)
transmitter will work up to 60 m
(195 feet) away from the vehicle.
There are other conditions which
can affect the performance of the
transmitter. See Remote Keyless
Entry (RKE) System on page 1‑3.
RKE without Remote Start Shown
The following may be available:
Q(Lock): Press to lock all doors.
The turn signal indicators may flash
and/or the horn may sound to
indicate locking, see “Remote
Lock Feedback” underVehicle
Personalization
on page 4‑36. If a
passenger door is open when
Qis
pressed, all doors lock. If the driver
door is open when
Qis pressed, all
doors lock except the driver door.
These settings can be modified.

Keys, Doors and Windows 1-11
Press and release&on the
liftgate adjacent to the latch to close
the liftgate.
Pressing any button, or the
touchpad switch while the liftgate is
moving stops it. Pressing the button
or RKE switch again reverses the
direction. The touch pad switch will
stop the liftgate from moving. There
is a minimum distance that the
power liftgate must already be open
for the system to hold it open.
If movement is stopped below that
minimum the liftgate closes. Do not force the liftgate open or
closed during a power cycle.
The power liftgate may be
temporarily disabled under extreme
temperatures or low battery
conditions. If this occurs, the liftgate
can still be operated manually.
If you shift the transmission out of
P (Park) while the power function is
in progress, the liftgate power
function will continue to completion.
If you shift the transmission out of
P (Park) and accelerate before the
power liftgate latch is closed, the
liftgate may reverse to the open
position. Cargo could fall out of the
vehicle. Always make sure the
power liftgate is closed and latched
before you drive away.
If you power open the liftgate and
the liftgate support struts have lost
pressure, the turn signals flash and
a chime sounds. The liftgate stays
open temporarily, then slowly
closes. See your dealer/retailer for
service before using the liftgate.
Obstacle Detection Features
If the liftgate encounters an obstacle
during a power open or close cycle,
a warning chime will sound and the
liftgate will automatically reverse
direction to the full closed or open
position. After removing the
obstruction, the power liftgate
operation can be used again. If the
liftgate encounters multiple
obstacles on the same power cycle,
the power function will deactivate.
The
“Manually Close Power Liftgate”
warning message in the Driver
Information Center (DIC) will
display. After removing the
obstructions, the liftgate will resume
normal power operation.
Your vehicle has pinch sensors
located on the side edges of the
liftgate. If an object is caught
between the liftgate and the body
and presses against this sensor, the
liftgate will reverse direction and
open fully. The liftgate will remain
open until it is activated again or
closed manually.

1-14 Keys, Doors and Windows
The system is automatically
disarmed when the vehicle is
started with the correct key. The key
uses a transponder that matches
an immobilizer control unit in the
vehicle and automatically disarms
the system. Only the correct key
starts the vehicle. The vehicle may
not start if the key is damaged.
The security light, located in the
instrument panel cluster, comes on
if there is a problem with arming or
disarming the theft-deterrent
system.
When trying to start the vehicle, the
security light comes on briefly when
the ignition is turned on.If the engine does not start and the
security light stays on there is a
problem with the system. Turn the
ignition off and try again.
If the engine still does not start, and
the key appears to be undamaged
or the light continues to stay on, try
another ignition key. If the engine
does not start with the other key, the
vehicle needs service. If the vehicle
does start, the first key may be
damaged. See your dealer/retailer
who can service the theft-deterrent
system and have a new key made.
Do not leave the key or device that
disarms or deactivates the theft
deterrent system in the vehicle.
Exterior Mirrors
Convex Mirrors
{WARNING
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.

(Continued)
WARNING (Continued)
movement could startle and
confuse you, or make you push a
pedal when you do not want to.
Adjust the driver's seat only when
the vehicle is not moving.
{WARNING
If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
Always push and pull on the
seatbacks to be sure they are
locked.

move when pushed or pulled.

Seats and Restraints 2-33
Additional windshield breakage may
also occur from the right front
passenger airbag.
.Airbags are designed to inflate
only once. After an airbag
inflates, you will need some new
parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another
crash. A new system will include
airbag modules and possibly
other parts. The service manual
for your vehicle covers the need
to replace other parts.
.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. SeeVehicle Data
Recording and Privacy
on
page 12‑15and Event Data
Recorders on page 12‑15.
.Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer/retailer
for service.
Passenger Sensing
System
The vehicle has a passenger
sensing system for the right front
passenger position. The passenger
airbag status indicator will be visible
on the overhead console when the
vehicle is started.
United States
Canada
The words ON and OFF, or the
symbol for on and off, are visible
during the system check. If you are
using remote start, if equipped, to
start the vehicle from a distance,
you may not see the system check.
When the system check is
complete, either the word ON or
OFF, or the symbol for on or off, will
be visible. See Passenger Airbag
Status Indicator on page 4‑15.

Seats and Restraints 2-35
The passenger sensing system is
designed to turn off the right front
passenger frontal airbag if:
.The right front passenger seat
is unoccupied.
.The system determines that an
infant is present in a child
restraint.
.A right front passenger takes
his/her weight off of the seat for
a period of time.
.Or, if there is a critical problem
with the airbag system or the
passenger sensing system.
When the passenger sensing
system has turned off the right front
passenger frontal airbag, the off
indicator will light and stay lit to
remind you that the airbag is off.
See Passenger Airbag Status
Indicator on page 4‑15. The passenger sensing system is
designed to turn on (may inflate)
the right front passenger frontal
airbag anytime the system senses
that a person of adult size is
sitting properly in the right front
passenger seat.
When the passenger sensing
system has allowed the airbag to be
enabled, the on indicator will light
and stay lit to remind you that the
airbag is active.
For some children, including
children in child restraints, and for
very small adults, the passenger
sensing system may or may not
turn off the right front passenger
frontal airbag, depending upon
the person’
s seating posture
and body build. Everyone in the
vehicle who has outgrown child
restraints should wear a safety belt
properly —whether or not there is
an airbag for that person.
{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. See Airbag Readiness
Light
on page 4‑15for more
information, including important
safety information.

2-38 Seats and Restraints
If the passenger seat gets wet, dry
the seat immediately. If the airbag
readiness light is lit, do not install a
child restraint or allow anyone to
occupy the seat. SeeAirbag
Readiness Light
on page 4‑15for
important safety information.
The on indicator may be lit if an
object, such as a briefcase,
handbag, grocery bag, laptop or
other electronic device, is put on an
unoccupied seat. If this is not
desired remove the object from
the seat.
{WARNING
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer/retailer and the service
manual have information about
servicing the vehicle and the airbag
system. To purchase a service
manual, see Service Publications
Ordering Information on page 12‑12.
{WARNING
For up to 10 seconds after the
ignition is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
(Continued)
WARNING (Continued)
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Q: Is there anything I might addto or change about the vehicle
that could keep the airbags
from working properly?
A: Yes. If you add things that
change the vehicle's frame,
bumper system, height, front end
or side sheet metal, they may
keep the airbag system from
working properly. Changing or
moving any parts of the front
seats, safety belts, the airbag
sensing and diagnostic module,
