SeeLower Anchors and Tethers for Children
(LATCH) on page 51if your child restraint has
a top tether.
You will be using the lap-shoulder belt to secure
the child restraint in this position. Be sure to follow
the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Your vehicle has a right front passenger’s
frontal airbag. SeePassenger Sensing System
on page 75. We recommend that rear-facing
child restraints be secured in a rear seat, even
if the airbag is off. If your child restraint is
forward-facing, move the seat as far back as it
will go before securing the child restraint in this
seat. SeePower Seats on page 9.
When the passenger sensing system has
turned off the right front passenger’s frontal
airbag, the off indicator in the passenger airbag
status indicator should light and stay lit when
you turn the ignition to RUN or START. See
Passenger Airbag Status Indicator on page 183.2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and
shoulder portions of the vehicle’s safety belt
through or around the restraint. The child
restraint instructions will show you how.
4. Buckle the belt. Make sure the release button
is positioned so you would be able to unbuckle
the safety belt quickly if you ever had to.

In many crashes severe enough to inate an airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur
from the right front passenger airbag.
Airbags are designed to inate only once. After
airbags inate, 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 other parts that need to be replaced.
Your vehicle has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Collection and
Event Data Recorders on page 489.
Let only qualied technicians work on the
airbag system. Improper service can mean that
your airbag system will not work properly. See
your dealer for service.
Passenger Sensing System
Your vehicle has a passenger sensing system. The
passenger airbag status indicator on the instrument
panel will be visible when you turn your ignition key
to RUN or START.
The passenger airbag
status indicator will
light ON and OFF for
several seconds as a
system check.
If you use remote start to start your vehicle from a
distance, if your vehicle has this feature, you may
not see the system check. When the system check
is complete, either the word ON or the word OFF
will be visible. SeePassenger Airbag Status
Indicator on page 183.
The passenger sensing system will turn off the
right front passenger’s frontal airbag under certain
conditions. The driver’s airbags are not part of
the passenger sensing system.

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be
serviced. There are parts of the airbag system in
several places around your vehicle. You do
not want the system to inate while someone is
working on your vehicle. Your dealer and the
service manual have information about servicing
your vehicle and the airbag system. To purchase a
service manual, seeService Publications
Ordering Information on page 495.
{CAUTION:
For up to 10 seconds, after the ignition is
turned off and the battery is disconnected,
an airbag can still inate during improper
service. You can be injured if you are
close to an airbag when it inates. Avoid
yellow connectors. 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
qualied to do so.
The airbag system does not need regular
maintenance.

bar-coded key tag. This tag may be removed
by your dealer before it is delivered.
The vehicle has the PASS-Key
®III vehicle theft
system. The key has a transponder in the
key head that matches a decoder in the vehicle’sinstrument panel. The key will have PK3 stamped
on it. If a replacement key or an additional key
is needed, it must be purchased from your dealer
or certied locksmith.
Any new PASS-Key
®III key must be programmed
before it will start the vehicle. SeePASS-Key®
III on page 106for more information on
programming a new key.
In an emergency, contact Roadside Assistance.
SeeRoadside Assistance Program on page 484
for more information.
Notice:If you ever lock your keys in your
vehicle, you may have to damage the vehicle
to get in. Be sure you have spare keys.

"(Unlock):Press the unlock button to unlock the
driver’s door. If the button is pressed again
within ve seconds, all remaining doors will unlock.
The interior lamps will come on and stay on for
20 seconds or until the ignition is turned on.
If enabled through the DIC, the parking lamps can
be programmed to come on for a set amount of
time when the vehicle is unlocked using the
RKE transmitter. See “EXT (Exterior) LIGHT
DELAY” underDIC Vehicle Personalization on
page 229. If the vehicle has the content
theft-deterrent system, pressing the unlock button
on the RKE transmitter may disarm it. See
Content Theft-Deterrent on page 104.
V(Remote Trunk Release):Press and hold
this button for about one second to release
the trunk lid. The transaxle must be in PARK (P)
for this feature to operate.
L(Panic Alarm):Press this button to activate the
alarm. The ignition must be in OFF or
ACCESSORY for the alarm to work. When the
alarm button is pressed, the headlamps will ash
and the horn will sound repeatedly for two minutes.
The alarm will turn off when the ignition is moved to
RUN or the alarm button is pressed again.
Matching Transmitter(s) to Your
Vehicle
Each RKE transmitter is coded to prevent another
transmitter from unlocking your vehicle. If a
transmitter is lost or stolen, a replacement can be
purchased through your GM dealer. Remember
to bring any additional transmitters so they
can also be re-coded to match the new transmitter.
Once your dealer has coded the new transmitter,
the lost transmitter will not unlock your vehicle.
The vehicle can have a maximum of four
transmitters matched to it.
Battery Replacement
Under normal use, the battery in the RKE
transmitter should last about four years.
The battery is weak if the transmitter will not work
at the normal range in any location. If you have
to get close to your vehicle before the transmitter
works, it is probably time to change the battery.
The KEY FOB BATT LOW message in the
vehicle’s DIC will display if the RKE transmitter
battery is low.

Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine
from outside of the vehicle. It may also start up
the vehicle’s heating or air conditioning systems
and rear window defogger. When the remote start
system is active, the climate control system will
heat or cool the inside of the vehicle based on the
outside temperature. The rear window defogger
will be turned on by the climate control system
when it is heating the inside of the vehicle. Normal
operation of the system will return after the key
is turned to the RUN position.
Laws in some communities may restrict the use of
remote starters. For example, some laws may
require a person using remote start to have
the vehicle in view when doing so. Check local
regulations for any requirements on remote starting
of vehicles.
Do not use the remote start feature if your vehicle
is low on fuel. Your vehicle may run out of fuel.The remote start feature provides two separate
starts per ignition cycle, each with 10 minutes
of engine running time.
The remote vehicle start feature needs to be reset
after your vehicle’s engine is started two times
using the transmitter’s remote start button.
The remote start system is reset by inserting the
vehicle’s key into the ignition switch and turning it
to RUN. SeeIgnition Positions on page 109for
information regarding the ignition positions on your
vehicle.
The RKE transmitter with the remote start button
provides an increased range of operation. You can
start your vehicle from an average range of about
492 feet (150 m) away. However the range may be
less while the vehicle is running, and as a result,
you may need to be closer to your vehicle to turn it
off than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote
Keyless Entry (RKE) System on page 89for
additional information.
93

/(Remote Start):If your vehicle has the remote
start feature, the RKE transmitter will have a
button with this symbol on it.
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 for four
seconds or until the turn signal lamps
ash. The vehicle’s doors will lock.
3. When the vehicle’s engine starts, the parking
lamps will turn on and remain on while the
engine is running.
The engine will shut off automatically after
10 minutes, unless a time extension has been
done or the vehicle’s key is inserted into
the ignition switch and turned to RUN.
If you enter the vehicle after a remote start,
and the engine is still running, insert the
key into the ignition switch and turn it to RUN
to drive the vehicle.4. To manually shut off a remote start, do any of
the following. The parking lamps will turn off:
Aim the RKE transmitter at the vehicle
and press the remote start button.
Turn on the hazard warning ashers.
Turn the ignition switch to RUN and
then to OFF.
Your vehicle’s engine may be started two times
using the transmitter’s remote start feature. If only
one remote start procedure has been done,
since last driving the vehicle, or resetting the
remote start system, the engine may be started
again remotely following the remote start
procedure a second time
If the remote start procedure is used again before
the rst 10 minute time frame has ended, the
rst 10 minutes will immediately expire and
the second 10 minute time frame will start.
