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 7-11.
{CAUTION:
For up to 10 minutes after the ignition key 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.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my airbag system?
A:Changing or moving any parts of the front seats,
safety belts, the airbag sensing and diagnostic
module (located under the right front passenger’s
seat), or the instrument panel can affect the
operation of the airbag system. If you have
questions, call Customer Assistance. The phone
numbers and addresses for Customer Assistance
are in Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 7-2.

This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications 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 the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
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.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-4.
If you are still having trouble, see your dealer or a
qualied technician for service.
Remote Keyless Entry System
Operation
The vehicle’s doors can be locked and unlocked, and
the trunk can be unlatched from about 3 feet (1 m) up to
60 feet (18 m) away with the remote keyless entry
transmitter.
If your vehicle has the remote start feature you can also
start your vehicle with the remote keyless entry
transmitter. Your remote keyless entry transmitter, with
the remote start button, provides an increased range
of operation. You can start your vehicle from an average
range of 492 feet (150 m) away. However, the range
may be less while the vehicle is running and 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 System on page 2-3.

V(Remote Trunk Release):Press this button to
release the trunk lid. The transaxle must be in PARK (P)
for this feature to operate.
L(Remote Alarm):Press this button to activate an
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 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 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 your remote keyless
entry transmitter should last about four years.
You can tell 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 remote keyless entry transmitter
battery is low.
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.
2-6

To replace the battery in the remote keyless entry
transmitter, do the following:
1. Insert a at object, with a thin edge, into the notch
located below the remote alarm button, and
separate the bottom half from the top half of the
transmitter.
2. Remove the old battery. Do not use a metal object
to do this.3. Slide the new battery into the transmitter with the
positive side of the battery facing up. Use a type
CR2032 battery, or equivalent type.
4. Snap the front and the back of the transmitter
together. Make sure the cover is on tight, so
water will not get in.
5. Test the operation of the transmitter with
the vehicle.
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 and the vehicle
has an automatic climate control system, it will
automatically regulate the inside temperature. Normal
operation of the system will return after the key is turned
to RUN.
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.
