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 589.
{CAUTION:
For up to 10 seconds 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.

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 eight transmitters matched
to it. See “Relearn Remote Key” underDIC
Operation and Displays (Using DIC Buttons) on
page 245orDIC Operation and Displays (Using
Trip Odometer Reset Stem) on page 250for
instructions on how to match RKE transmitters to
your vehicle.
Battery Replacement
Under normal use, the battery in your RKE
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 REPLACE BATTERY IN REMOTE KEY
message in the vehicle’s DIC will display if the
RKE transmitter battery is low. See “REPLACE
BATTERY IN REMOTE KEY” underDIC Warnings
and Messages on page 252for additional
information.
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.
118

To replace the battery in the RKE transmitter do
the following:
1. Use a at object with a thin edge into the
notch, located below the trunk release
button, and separate the bottom half from
the top half of the transmitter.
2. Remove the old battery, but 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 down.
Use a type CR2032 battery, or equivalent
type. Make sure the cover is on tightly,
so water will not get in.
4. Snap the front and the back of the transmitter
together.
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. Normal operation of the
system will return after the key is turned to the
RUN position.If your vehicle has an automatic climate control
system, during remote start, the climate control
system will default to a heating mode during colder
outside temperatures and a cooling mode during
warmer outside temperatures. If your vehicle
does not have an automatic climate control
system, during remote start the climate control
system will turn on at the setting the vehicle was
set to when the vehicle was last turned off.
Laws in some communities may restrict the use of
remote starters. For example, some laws may
require a person using the 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 RKE transmitter with the remote start button,
provides an increased range of operation. However,
the range may be less while the vehicle is running.
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 System on page 114for additional
information.
