battery replacement GMC SIERRA 2003 Owner's Manual

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 or
resynchronization is necessary. See“Battery
Replacement”and‘‘Resynchronization’’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
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.
UNLOCK:Pressing this button once will unlock
the driver’s door. The interior lamps will come on.
Pressing UNLOCK again within three seconds will cause
the remaining doors to unlock.
You can choose different feedback options for each
press of the UNLOCK button. SeeDIC Operation and
Displays on page 3-42for more information.
LOCK:Pressing this button once will lock all of the
doors. You can choose different feedback options
for each press of the LOCK button. SeeDIC Operation
and Displays on page 3-42for more information.
Operating the keyless entry transmitter may interact with
the theft-deterrent system. SeeContent Theft-Deterrent
on page 2-13andDIC Operation and Displays on
page 3-42for more information.
Remote Alarm
When the horn symbol on the keyless entry transmitter
is pressed, the horn will sound and the headlamps
and taillamps willash 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 a maximum of 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.To replace the battery in the keyless entry transmitter,
do the following:
1. Insert a thin coin, or similar object, in the slot
between the covers of the transmitter housing
near the key ring hole. Remove the bottom
by twisting the coin.
2. Remove and replace the battery with a three-volt
CR2032 or equivalent battery, positive (+) side up.
3. Align the covers and snap them together.
4. Resynchronize the transmitter.
5. Check the operation of the transmitter.

Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your
vehicle was designed and tested with top-quality GM
brake parts. When you replace parts of your braking
system–for example, when your brake linings
wear down and you need new ones put in–be sure
you get new approved GM replacement parts.
If you don’t, your brakes may no longer work properly.
For example, if someone puts in brake linings that
are wrong for your vehicle, the balance between your
front and rear brakes can change—for the worse.
The braking performance you’ve come to expect can
change in many other ways if someone puts in the
wrong replacement brake parts.
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. SeeEngine Compartment Overview on
page 5-12for battery location.
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.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or
more, remove the black, negative (−) cable from
the battery. This will help keep your battery from
running down.
{CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren’t careful. See“Jump Starting”next for
tips on working around a battery without
getting hurt.
Contact your dealer to learn how to prepare your
vehicle for longer storage periods.
Also, for your audio system, seeTheft-Deterrent
Feature on page 3-75.
