2003 GMC YUKON DENALI battery replacement

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:
e
e
e
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
2-5.
If you are still having trouble, see your dealer or a
qualified 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.
a (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, such as having the vehicle’s
perimeter lamps come on and/or having the horn
chirp. See
DIC Operation and Displays on page 3-43 for
more information.
2-5

8 (Lock): Pressing this button once will lock all of the
doors. Pressing the button again within three seconds
may cause the horn
to chirp for lock confirmation.
You can choose different feedback options for each
press of the lock button, such as having the vehicle’s
perimeter lamps flash and/or having the horn chirp. See
DIC Operation and Displays on page 3-43 for more
information.
& (Panic): When this button is pressed, the horn will
sound and the headlamps and taillamps will flash for
up
to 30 seconds. This can be turned off by pressing the
button again, or by waiting for
30 seconds, or by
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.

Brake Pedal Travel Battery
See your dealer if the brake pedal does not return to
normal height, or
if there is a rapid increase in
pedal travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes
adjust for wear.
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. 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. See Engine Compartment Overview
on
page 5-72 for 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
+‘-? battery. This will hc’- keep your battery from
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.
