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 remaining transmitters with you when you go
to your dealer. Each 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.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 vehicle locator/panic alarm
button, and separate the bottom half from the top
half of the transmitter.
2. Remove the battery and replace it with the new
one. Make sure the positive (+) side of the battery
faces up. Use one three-volt, CR2032, or equivalent
type battery.
3. Put the two halves back together. Make sure the
cover is on tight, so water will not get inside the
transmitter.
4. Test the operation of the transmitter with the
vehicle.

Remote Vehicle Start
Your vehicle may have a remote start feature. This
feature allows you to start the engine from outside the
vehicle. It may also start 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 may automatically
regulate the inside temperature. Normal operation of the
system will return after the key is turned to ON.
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,
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 ON. SeeIgnition
Positions on page 2-22for information regarding the
ignition positions on your vehicle.
You can start your vehicle’s engine from approximately
197 feet (60 m) away. However, the range may beless 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 may affect the
performance of the transmitter, seeRemote Keyless
Entry System on page 2-4.
/(Remote Start):If your vehicle has the remote start
feature, the keyless entry 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 until the vehicle’s turn signal
lights ash.
3. When the vehicle 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 ON.
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 ON 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 remote keyless entry transmitter at the
vehicle, and press the remote start button.
Turn on the hazard warning ashers.
Turn the ignition switch to ON and then to OFF.
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 by
following the remote start procedure a second time.
If the remote start procedure is used again before the
rst ten minute time frame has ended, 10 minutes will be
added to the remaining minutes. The added 10 minutes
are considered a second remote start.
The remote vehicle start feature will not operate if any
of the following occur:
The remote start system is disabled through the DIC.
The vehicle’s key is in the ignition.
The vehicle’s hood is open.
The hazard warning ashers are on.
The check engine light is on. SeeMalfunction
Indicator Lamp on page 3-41.
The engine coolant temperature is too high.
The oil pressure is low.
Two remote vehicle starts have already been
provided.
Vehicles that have the remote vehicle start feature are
shipped from the factory with the remote vehicle
start system enabled. The system may be enabled or
disabled through the DIC. See “REMOTE START” under
DIC Operation and Displays on page 3-47for additional
information.
Remote Start Ready
If your vehicle does not have the remote vehicle start
feature, it may have the remote start ready feature. This
feature allows your dealer to add the manufacturer’s
remote vehicle start feature.
If the keyless entry transmitter has a plus (+) symbol on
the back cover, your vehicle has the remote start
ready feature. You can lock or unlock your vehicle from
approximately 197 feet (60 m) away.
See your dealer if you would like to add the
manufacturer’s remote vehicle start feature to your
vehicle.

suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.There are several ways to lock and unlock your vehicle.
From the outside, use your key or remote keyless
entry transmitter, if equipped. Turn the key
