2-11
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
The average range of this system is about 10 feet (3 m).
At times you may notice a decrease in range. This is
normal for any remote keyless entry transmitter.
If the transmitter does not work or if you have to
stand closer to your vehicle for the transmitter to work,
try the following:

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 the instructions that follow.

If you're still having trouble, see your dealer or
a qualified technician for service.Operation
(Lock): When you
press this symbol to lock the

the theft
-deterrent system.
The parking lamps will not flash, however, if the manual
parking lamps are left on. Remote confirmation is not
operational if a door is open.
You can program your vehicle so the parking lamps
will not flash and the horn will not sound. For more
information, see ªVehicle Programming and
Personalization Featuresº in the Index.
(Unlock): When you press this button to unlock
the driver's door, the parking lamps on your vehicle
will flash twice. The parking lamps will not flash if they
have been turned on manually. Remote confirmation is
not operational if a door is open.

2-13 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 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.
1. Use an object like a coin to pry open the transmitter.

Battery
Your new vehicle comes with a maintenance free
ACDelco
battery. When it's time for a new battery,
get one that has the replacement number shown on
the original battery's label. We recommend an
ACDelco battery.
WARNING: Battery posts, terminals and related
accessories contain lead and lead compounds, chemicals
known to the State of California to cause cancer and
reproductive harm. Wash hands after handling.
The battery is located under the rear seat cushion. To
access the battery, see ªRemoving the Rear Seat
Cushionº in the Index. You don't need to access the
battery to jump start your vehicle. See ªJump Startingº
in the Index.
CAUTION:
A battery that isn't properly vented can let
sulfuric acid fumes into the area under the rear
seat cushion. These fumes can damage your rear
seat safety belt systems. You may not be able to
see this damage, and the safety belts might not
provide the protection needed in a crash. If a
replacement battery is ever needed, it must be
vented in the same manner as the original
battery. Always make sure that the vent hose is
properly reattached before reinstalling the
seat cushion.
