the power function is in progress, the liftgate
power function will continue to completion. If you

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 liftgate may be
power opened or closed normally. If the liftgate
encounters multiple obstacles on the same power
cycle, the power function will deactivate, and
the liftgate will switch to manual operation. The
REAR ACCESS OPEN warning message in
the Driver Information Center (DIC) will indicate
that the liftgate is open. After removing the
obstructions, manually open the liftgate to the full
open position or close the liftgate to the fully
closed and latched position. The liftgate will now
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 vehicle 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.
Manual Operation of Power Liftgate
To change the liftgate
to manual operation,
toggle the switch on the
overhead console to
the “Disable” position
indicated by a circle.
With the power liftgate disabled and the door
unlocked, the power liftgate can be manually
opened and closed.
To open the liftgate, press the touchpad on the
handle on the outside of the liftgate, and lift
the gate open. To close the liftgate, use the pull
cup or pull strap to lower the liftgate and close.
The liftgate latch will power cinch to closed
position. Always close the liftgate before driving.
If the RKE button or the power close button on
the liftgate is pressed while power operation
is disabled, the lights will ash three times, but
the liftgate will not move.
130

When driving with the liftgate open, the power
liftgate should be switched to manual liftgate
operation — the overhead console switch set to
the “Disable” position.
Both the liftglass and liftgate have an electric
latch. If the battery is disconnected or has
low voltage, the liftglass and liftgate will not open.
The liftglass and liftgate will resume operation
when the battery is reconnected and charged.
If the battery is properly connected and has
adequate voltage, and the liftgate or liftglass still
will not function, your vehicle should be taken to a
dealership for service.
{CAUTION:
It can be dangerous to drive with the
liftglass or liftgate open because carbon
monoxide (CO) gas can come into your
vehicle. You cannot see or smell CO. It
can cause unconsciousness and even
death.
CAUTION: (Continued)
CAUTION: (Continued)
If you must drive with the liftglass or
liftgate open, or if electrical wiring or
other cable connections must pass
through the seal between the body and
the liftglass or liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
with the recirculation mode off. That
will force outside air into your vehicle.
SeeDual Automatic Climate Control
System on page 214.
If you have air outlets on or under
the instrument panel, open them all
the way.
If your vehicle is equipped with a
power liftgate, disable the power
liftgate function.
SeeEngine Exhaust on page 156.
Do not drive with the liftgate open if at all possible.
131

Power Running Boards
Your vehicle may have power running boards.
These make getting into and out of the vehicle
easier.
The power running boards activate when either
door on the driver’s or passenger’s side is opened
or closed. They automatically extend from
beneath the vehicle on the side in which the door
has been opened. Once the door is closed, the
running boards will automatically move back under
the vehicle. The vehicle must be stationary for
the running boards to extend or retract.
The switch used to
disable the power
running boards is
located on the center
console below the
climate control system.
The running boards cannot be disabled in the
extended position.
Windows
{CAUTION:
Leaving children, helpless adults, or pets
in a vehicle with the windows closed is
dangerous. They can be overcome by
the extreme heat and suffer permanent
injuries or even death from heat stroke.
Never leave a child, a helpless adult, or a
pet alone in a vehicle, especially with the
windows closed in warm or hot weather.
132

Power Windows
The power window
controls are located
on each of the
side doors.
The driver’s door has a switch for the passenger

fully on the window switch, then release, to activate
the express-down mode. The express-down mode
can be canceled at any time by pulling up on the

(Window Lockout):The window lockout
switch is located with the power window switches
on the driver’s door armrest. This feature
prevents the rear passenger windows from

both the driver’s and passenger’s sun visors. Pull
the sun visor down and lift the mirror cover to
turn the lamps on.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some
cities. Although your vehicle has a number of
theft-deterrent features, we know that nothing we
put on it can make it impossible to steal.
134

Content Theft-Deterrent
Your vehicle has a content theft-deterrent alarm
system.
This is the security light.
To activate the theft-deterrent system, do the
following:
1. Open the door.
2. Lock the door with the remote keyless entry
(RKE) transmitter. The security light should
come on and stay on.
3. Close all doors. The security light should go
off after about 30 seconds. The alarm is not
armed until the security light goes off.
If a locked door is opened without using the RKE
transmitter, a ten second pre-alarm will occur.
The horn will chirp and the lights will ash.If the door is not unlocked by pressing the unlock
button on the remote keyless entry transmitter
during the ten second pre-alarm, the alarm will
go off. The headlamps and parking lamps will ash
for two minutes, and the horn will sound for
30 seconds, then will turn off to save the battery
power. You can choose different feedback options
for the alarm. SeeDriver Information Center
(DIC) on page 244Driver Information Center (DIC).
Remember, the theft-deterrent system will not
activate if you lock the doors with a key, the
manual door lock, or the power door lock switch.
It activates only if you use the RKE transmitter.
You should also remember that you can start your
vehicle with the correct ignition key if the alarm
has been set off.
135

Here is how to avoid setting off the alarm by
accident:
If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the
door key after the doors are closed.
Always unlock a door with the RKE transmitter.
Unlocking a door any other way will set off
the alarm.
If you set off the alarm by accident, turn off the
alarm by pressing the unlock button on the
RKE transmitter. The alarm will not stop if you try
to unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s
window and open the driver’s door.
2. Activate the system by locking the doors with
the RKE transmitter.
3. Get out of the vehicle, close the door and wait
for the security light to go out.
4. Then reach in through the window, unlock the
door with the manual door lock and open the
door. This should set off the alarm.While the alarm is set, the power door unlock
switch will not work.
If the alarm does not sound when it should but the
headlamps ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
seeFuses and Circuit Breakers on page 538.
If the alarm does not sound or the headlamps do
not ash, the vehicle should be serviced by
your dealer.
