GMC SIERRA DENALI 2003 Manual Online

If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have LATCH
system, safety belt or seat parts repaired or replaced.
New parts and repairs may be necessary even
if the belt
or LATCH system wasn’t being used at the time of
the collision.
If an air bag inflates, you’ll need to replace air bag
system parts. See the part on the air bag system earlier

locks as well as the spare
tire hoist lock,
if equipped.
If you ever lose your keys, your dealer will be able to

of
trouble getting into your vehicle if you ever lock
your keys inside. You may even have to damage
your vehicle to get in.
So be sure you have
spare keys.
If you ever do get locked out of your vehicle, call the
GM Roadside Assistance Center. See Roadside
Assistance Program
on page 7-5. If your vehicle is
equipped with the Onstar@ system with an active subscription
and you lock your keys inside the vehicle,
OnStar@ may be able
to send a command to unlock
your vehicle. See

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.
CR2032 or equivalent battery, positive
(+) side up.
2. Remove and replace the battery with a three-volt
3. Align the covers and snap them together.
4. Check the operation of the transmitter.

be removed without assistance, you may want someone
to assist you with the removal to avoid possible
damage to the vehicle.

1. Raise the tailgate
slightly and release
both retaining
cable clips. To release
the retaining cable clips, lift the cable
so it
points straight out
and push the cable clip
forward.
2. With the tailgate at a
slight upward angle,
pull back on the tailgate
at the right edge and
then move the
tailgate to the right to
release the left edge.
Reverse the above procedure to reinstall. Make sure the
tailgate is secure.
