CAUTION:
When an air bag inflates, there is dust in the air.
This dust could cause breathing problems for
people with a history of asthma or other
breathing trouble. To avoid this, everyone in the
vehicle should get out as soon as it is safe to do so.
If you have breathing problems but can't get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window or door.
In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.

Air bags are designed to inflate only once. After they
inflate, you'll need some new parts for your air bag
system. If you don't get them, the air bag system
won't be there to help protect you in another crash.
A new system will include air bag modules and
possibly other parts. The service manual for your
vehicle covers the need to replace other parts.
Your vehicle is equipped with a crash sensing and
diagnostic module, which records information about
the air bag system. The module records information
about the readiness of the system, when the
sensors are activated and driver's safety belt usage
at deployment.

Let only qualified technicians work on your air
bag system. Improper service can mean that your
air bag system won't work properly. See your dealer
for service.
NOTICE:
If you damage the covering for the driver's or the
right front passenger's air bag, the bag may not
work properly. You may have to replace the air
bag module in the steering wheel or both the air
bag module and the instrument panel for the
right front passenger's air bag. Do not open or
break the air bag coverings.

If your vehicle ever gets into a lot of water -- such as
water up to the carpeting or higher
-- or if water enters
your vehicle and soaks the carpet, the air bag controller
can be soaked and ruined. If this ever happens, and then
you start your vehicle, the damage could make the air
bags inflate, even if there's no crash. You would have to
replace the air bags as well as the sensors and related
parts. If your vehicle is ever in a flood, or if it's exposed
to water that soaks the carpet, you can avoid needless
repair costs by turning off the vehicle immediately and
disconnecting the battery cables. Don't let anyone start
the vehicle under any circumstances. See your dealer
for service.AIR BAG OFF Switch
Your vehicle has a switch on the instrument panel
that you can use to turn off the right front passenger's
air bag.

yellowblue
1-33
To turn off the right front passenger's air bag, insert
your ignition key into the switch, push in, and move the
switch to AIR BAG OFF.
The AIR BAG OFF light will come on to let you know
that the right front passenger's air bag is off. The right
front passenger's air bag will remain off until you turn it
back on again, and the AIR BAG OFF light will stay on
to remind you that the air bag is off.
CAUTION:
If the air bag readiness light ever comes on when
you have turned off the air bag, it means that
something may be wrong with the air bag system.
The right front passenger's air bag could inflate
even though the switch is off.
If your vehicle is a regular cab pickup and this
ever happens, don't let anyone whom the
national government has identified as a member
of a passenger air bag risk group sit in the right
front passenger's position (for example, don't
secure a rear
-facing child restraint in your
vehicle) until you have your vehicle serviced.
If your vehicle is an extended cab pickup and this
ever happens, don't let anyone whom the
national government has identified as a member
of a passenger air bag risk group sit in the right
front passenger's position (for example, don't
secure a rear
-facing child restraint in the right
front passenger's seat) until you have your
vehicle serviced.

To turn the right front passenger's air bag on again,
insert your ignition key into the switch, push in, and
move the switch to the ON position.
Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag system in several places
around your vehicle. You don't want the system to
inflate while someone is working on your vehicle. Your
dealer and the GM Service Manual have information
about servicing your vehicle and the air bag system. To
purchase a service manual, see ªService and Owner
Publicationsº in the Index.
CAUTION:
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are close to an air bag when
it inflates. Avoid wires wrapped with yellow tape
or yellow connectors. They are probably part of
the air bag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualified to do so.
The air bag system does not need regular maintenance.

CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag inflates, even though your
vehicle has Next Generation frontal air bags. This
is because the back of the rear
-facing child
restraint would be very close to the inflating air
bag. Be sure to turn off the air bag before using a
rear
-facing child restraint in the right front seat
position. If a forward
-facing child restraint is
suitable for your child, always move the
passenger seat as far back as it will go.
Although a rear seat is a safer place, you can secure a
forward
-facing child restraint in the right front seat.
CAUTION:
If the air bag readiness light ever comes on when
you have turned off the air bag, it means that
something may be wrong with the air bag system.
The right front passenger's air bag could inflate
even though the switch is off.
If your vehicle is a regular cab pickup and this
ever happens, don't let anyone whom the
national government has identified as a member
of a passenger air bag risk group sit in the right
front passenger's position (for example, don't
secure a rear
-facing child restraint in your
vehicle) until you have your vehicle serviced.
See ªAIR BAG OFF Switchº in the Index.

CAUTION: (Continued)
If your vehicle is an extended cab pickup and this
ever happens, don't let anyone whom the
national government has identified as a member
of a passenger air bag risk group sit in the right
front passenger's position (for example, don't
secure a rear
-facing child restraint in the right
front passenger's seat) until you have your
vehicle serviced. See ªAIR BAG OFF Switchº in
the Index.
You'll be using the lap-shoulder belt. See the earlier part
about the top strap if the child restraint has one. 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 air bag. If
you are using a rear
-facing child restraint in this seat,
make sure the air bag is turned off. (See ªAIR BAG
OFF Switchº in the Index.) If your child restraint is
forward
-facing, always move the seat as far back as
it will go before securing it in this seat. (See ªSeatsº
in the Index.)
2. Put the 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.
If the shoulder belt goes in front of the child's face or
neck, put it behind the child restraint.

The power door locks will operate at any time without
the ignition being on.
The power door locks will also automatically lock when
the vehicle reaches 15 mph (24 km/h). To unlock the
doors, refer to the instructions listed previously. The
automatic locking feature can be disabled, if you prefer.
See your dealer for assistance.
Operating the power locks may interact with the
theft
-deterrent system. See ªContent Theft-Deterrentº
in the Index.
Lockout Prevention
To protect you from locking your key in the vehicle, this
feature stops the power door locks from locking when
the keys are in the ignition and a door is open.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all of the doors will lock
and then the driver's door will unlock.
Keyless Entry System (If Equipped)
If your vehicle has this option, you can lock and unlock
your doors from about 3 feet (1 m) up to 100 feet (30 m)
away using the remote keyless entry transmitter supplied
with your vehicle.
Your keyless entry system operates on a radio frequency
subject to Federal Communications Commission (FCC)
Rules and with Industry Canada.This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause undesired operation.
This device complies with RSS
-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this device
must accept any interference received, including interference
that may cause undesired operation of the device.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer to
your vehicle for the transmitter to work, try this:

Check to determine if battery replacement or
resynchronization is necessary. See the instructions
that follow.

Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.

2-7

Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.

If you're still having trouble, see your dealer or a
qualified technician for service.
Operation
UNLOCK: Pressing this button once will unlock the
driver's door. The parking lamps will flash and the
interior lights will come on. Pressing UNLOCK again
within three seconds will cause the remaining doors to
unlock. The parking lamps will flash and the interior
lights will come on.
LOCK: Pressing this button once will lock all of the
doors. Press LOCK again within three seconds and the
horn will chirp.
Operating the keyless entry transmitter may interact
with the theft
-deterrent system. See ªContent-Theft
Deterrentº in the Index.
Remote Panic Alarm
When the button with the horn symbol on the key
transmitter is pressed, the horn will sound and the
headlamps and taillamps will flash for up to 30 seconds.
This can be turned off by pressing the horn button again,
waiting for 30 seconds, or starting the vehicle.
Matching Transmitter(s) To Your Vehicle
Each remote keyless entry 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 dealer. Remember to bring any remaining
transmitters with you when you go to your dealer. When the
dealer matches the replacement transmitter to your vehicle,
any remaining transmitters must also be matched. Once your
dealer has coded the new transmitter, the lost transmitter will
not unlock your vehicle. Each vehicle can have only four
transmitters matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won't work
at the normal range in any location. If you have to get close to
your vehicle before the transmitter works, it's probably time
to change the battery.
NOTICE:
When replacing the battery, use care not to touch any
of the circuitry. Static from your body transferred to
these surfaces may damage the transmitter.
