GMC SIERRA 1996 Repair Manual

Replacing Restraint System Parts
After a Crash
If you’ve had a crash, do you need new belts‘?
After a very minor collision, nothing may be necessary.
But
if the belts were stretched, as they would be if worn
during a more severe crash, then
you need new belts.
If you ever see a label on the right front passenger’s
safety belt in an Extended Cab model that says
to
replace the belt, be sure to do so. Then the new belt will
be there to help protect
you in a collision. You would
see this label on the belt near the door opening.
If belts are cut or damaged, replace them. Collision
damage also may mean
you will need to have safety belt
or seat parts repaired or replaced. New parts and repairs
may be necessary even
if the belt 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
in this section.

Keys
Leaving young children in a vehicle with the

even killed.

controls
or even make the vehicle move. Don’t
leave the keys in a vehicle with young children.

Your vehicle has one
double-sided key for the
ignition and all door locks.
If you ever lose your keys, your dealer will be able to
assist
you with obtaining new ones.
NOTICE:
Your vehicle has a number of new features that
can help prevent theft. But you can have a lot of
.
trouble getting into your vehicle if you ever lock
your key inside. You may even have to damage
your vehicle to get in.
So be sure you have an
extra key.
Tailgate
You can open the tailgate by lifting up on its handle
while
pulling t.he tailgate toward you.

you put the tailgate back up, pull it back towara
you, to be sure that it latches securely.

for different loading situations. Although the tailgate
can be removed without assistance,

~ Door Locks There
are several ways to lock and .unlock your vehicle. I
I
Unlocked doors can be dangerous.
Passengers
-- especially children -- can easily
open the doors and fall out. When a door is
locked, the inside handle won't open it.
Outsiders can easily enter through an unlocked
door when you slow down or stop your vehicle.
This may not be so obvious: You increase the
chance of being thrown out of the vehicle in
a
crash if the doors aren't locked. Wear safety belts
properly, lock your doors, and you
will be far
better off whenever you drive your vehicle.
From the outside, use your key or the Keyless Entry
System, if.your vehicle has this option.
To lock the door from the
inside, slide the lever
on
your door down.
To unlock the door, slide the lever up.

Matching Transmitter(s) To Your Vehicle
Each key chain 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 the new transmitter
is coded, the lost
transmitter will
not unlock your vehicle. Each vehicle
can have only two transmitters matched to
it.
Battery Replacement
Under normal use. the batteries in your key chain
transmitter should last
about two years.
You can tell the batteries are 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 batteries.
Use two Duraeell@ batteries type
DL2014, or a
similar type.

To replace the batteries: rheft
1. Insert a dime in the side seam of the transmitter
housing, near
the key ring hole.
2. Twist the dime to separate the two halves of the
transmitter housing. Separate the housing, bottom
half first.
3. Remove and replace the batteries. Put the new
batteries
in with the printed side down.
4. Align the housing and snap the halves together. Vehicle theft is big business, especially
in some cities.
Although your vehicle has
a number of theft-deterrent
features, we know that nothing
we put on it can make it
impossible to steal. However, there are ways you can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for joy riders or professional thieves
-- so
don’t do
it.
When you park your vehicle and open the driver’s door,
you’ll hear a tone reminding you to remove your key
from the ignition and take
it with you. Always do this.
Your steering wheel
will be locked, and so will your
ignition.
If you have an automatic transmission, taking
your key out also locks
your transmission. And
remember to lock
the doors.

vehicle. Remember
to keep your valuables out of sight.
Put
them in a storage area, or take them with you.
Parking Lots

your vehicle, it’s best
to lock it up and take your keys.

you have to leave something valuable in your vehicle?
0 Put your valuables in a storage area, like your
glove
box.
0 Lock all the doors except the driver‘s.
NOTICE:

“break-in.” But it
will perform better in the long
run
if you follow these guidelines:
0
0
0
0
Keep your speed at 55 mph (88 km/h) or
less for the first
500 miles (804 km).

-- fast or
slow
-- for the first 500 miles (804 km).
Don’t make full-throttle starts.
Avoid making hard stops for the
first
200 miles (322 km) or so. During this time
