Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder
light and all your belts, buckles, latch plates,
retractors and anchorages are working properly.
Look for any other loose or damaged safety
belt system parts. If you see anything that might
keep a safety belt system from doing its job, have
it repaired. Keep safety belts clean and dry.
SeeCare of Safety Belts on page 531for more
information.
Torn or frayed safety belts may not protect you in
a crash. They can rip apart under impact forces.
If a belt is torn or frayed, get a new one right away.Also look for any opened or broken airbag
covers, and have them repaired or replaced.
(The airbag system does not need regular
maintenance.)
Notice:If you damage the covering for the
driver’s or the right front passenger’s airbag,
or the side impact airbag covering on the
ceiling near the side windows, the airbag may
not work properly. You may have to replace
the airbag module in the steering wheel, both
the airbag module and the instrument panel
for the right front passenger’s airbag, or
side impact airbag module and ceiling covering
for roof-mounted rollover airbags (if equipped.)
Do not open or break the airbag coverings.

Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems
in your vehicle. A damaged restraint
system may not properly protect the
person using it, resulting in serious injury
or even death in a crash. To help make
sure your restraint systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as possible.
If you have had a crash, do you need new belts or
LATCH system parts?
After a very minor collision, nothing may be
necessary. But if the belts were stretched, as they
would be if worn during a more severe crash,
then you need new parts.
If the LATCH system was being used during a
more severe crash, you may need new LATCH
system parts.If belts are cut or damaged, replace them.
Collision damage also may mean you will need to
have LATCH system, safety belt or seat parts
repaired or replaced. New parts and repairs may
be necessary even if the belt or LATCH system
was not being used at the time of the collision.
If an airbag inates, you will need to replace airbag
system parts. See the part on the airbag system
earlier in this section.
If the airbags inate you will also need to replace
the driver and front passenger’s safety belt
retractor assembly. Be sure to do so. Then the
new retractor assembly will be there to help protect
you in a collision.
After a crash you may need to replace the driver
and front passenger’s safety belt retractor
assemblies, even if the airbags have not deployed.
The driver and front passenger’s safety belt
retractor assemblies contain the safety belt
pretensioners. Have your safety belt pretensioners
checked if your vehicle has been in a collision, or if
your airbag readiness light stays on after you start
your vehicle or while you are driving. SeeAirbag
Readiness Light on page 227.

To start the vehicle using the remote start feature,
do the following:
1. Aim the transmitter at the vehicle.
2. Press and release the transmitter’s lock button,
then immediately press and hold the
transmitter’s remote start button until the turn
signal lights ash. If you can not see the
vehicle’s lights, press and hold the remote start
button for at least four seconds. The vehicle’s
doors will lock. Pressing the remote start button
again after the vehicle has started will turn off
the ignition.
When the vehicle starts, the parking lamps will
turn on and remain on while the vehicle is
running.
3. If it is your rst remote start since last driving,
repeat these steps while the engine is still
running for a 10 minute time extension.
Remote start can be extended one time.
When you enter the vehicle during a remote start,
and the engine is still running, turn the key to
the RUN position to drive the vehicle.
If the vehicle is left running it will automatically
shut off after 10 minutes unless a time extension
has been done.To manually shut off a remote start, do any of the
following:
Aim the remote keyless entry transmitter at
the vehicle and press the remote start
button until the parking lamps turn off.
Turn on the hazards warning ashers.
Turn the ignition switch on and then off.
The vehicle can be remote started two separate
times between driving sequences. The engine will
run for 10 minutes after each remote start.
Or, you can extend the engine run time by another
10 minutes within the rst 10 minute remote
start time frame, and before the engine stops.
For example, if the lock button and then the remote
start buttons are pressed again after the vehicle has
been running for ve minutes, 10 minutes are
added, allowing the engine to run for 15 minutes.
The additional ten minutes are considered a
second remote vehicle start.
Once two remote starts, or a single remote start
with one time extension has been done, the
vehicle must be started with the key.
After the key is removed from the ignition, the
vehicle can be remote started again.

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 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.

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.
Content Theft-Deterrent
Your vehicle may have a content theft-deterrent
alarm system.
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 ash. The door does not need to
be open.
If the delayed locking feature is active, the
alarm will not be activated until all doors are
closed and the security light goes off.
3. Close all doors. The security light will stop
ashing and go off after approximately
30 seconds. The content theft deterrent alarm
is not armed until the security light goes off.
132

If a 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
key is not placed in the ignition and turned to
START or the door is not unlocked by pressing the
unlock button on the RKE transmitter during the
ten second pre-alarm, the alarm will go off.
Your vehicle’s headlamps will ash and the horn
will sound for about two minutes, then will turn
off to save the battery power.
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.
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 the system has been armed.If you set off the alarm by accident, turn off the
alarm by pressing unlock on the RKE transmitter or
by placing the key in the ignition and turning it
to START.
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.
If the alarm does not sound when it should, but
the vehicle’s 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 540.
If the alarm does not sound or the vehicle’s
headlamps do not ash, see your dealer for
service.
