1995 GMC SIERRA ignition

NOTICE:
If you damage the cover for the driver’s air bag, it may not work\

properly. You may have to replace the air bag module.
Do not
open or break the air bag cover.
Servicing Your Air Bag-Equipped Vehicle
The air bag affects how your vehicle should be serviced. There are parts of
the air bag system in several places around your vehicle. You don’t want the
system to inflate while someone is working on your vehicle. Your
GM
dealer and the 1995 GM Service Manual have information about servicing
your vehicle and the air bag system. To purchase
a service manual, see
”Service Publications”
in the Index. The air bag system does not need
regular maintenance.
A CAUTION:
For up to 2 minutes after the ignition key is turned off and the
battery is disconnected, an air bag can still inflate during
improper service.
You can be injured if you are close to an air
bag when it inflates.
Avoid wires wrapped with yellow tape, or
yellow connectors. They are probably part of the air bag system.
Be sure to follow proper service procedures, and make sure the
person performing work for you
is qualified to do so.
Adding Equipment to Your Air Bag-Equipped Vehicle
Q: If I add a push bumper or a bicycle rack to the front of my vehicle,
will it keep the air bag from working properly?
A: As long as the push bumper or bicycle rack is attached to your vehicle
so that the vehicle‘s basic structure isn’t changed. it‘s not likely to keep
the air bags from working properly
in a crash.
Q: What if I add a wow plow? Will it keep the air bag from working
properly?
A: We’ve designed our air bag systems to work properly under a wide
range
of conditions. including snow plowing with vehicles equipped
with the optional Snow Plow Prep Package
(RPO VYU). But don’t
change or defeat the snow plow’s “tripping mechanism.”
If you do, it
can damage your snow plow and your vehicle, and it may cause an air
bag inflation.

Key in the Ignition
If you walk away from 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.
Parking at Night
Park in a lighted spot, close all windows and lock your vehicle. Remember
to keep
your valuables out of sight. Put them in a storage area, or take them
with
you.

to lock
it up and take your keys. But what if you have to leave your ignition
key? What if
you have to leave something valuable in your vehicle?
Put your valuables in a storage area, like your glove box.
Lock all the doors except the driver’s.
New Vehicle “Break-In ”
NOTICE:
Your modern vehicle doesn’t need an elaborate “break-in.” But
it will perform better in the long run if you follow these
guidelines:
Keep your speed at 55 mph (88 km/h) or less for the first 500
miles (804 km).
Don’t drive at any one speed - 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 your new brake linings aren’t yet broken
in. Hard stops with new linings can mean premature wear and
earlier replacement. Follow this “breaking-in” guideline
every time you get new brake linings.
Don’t tow a trailer during “break-in.” See “Towing a Trailer”
in the Index
for more information.

to five different positions:
2
5
1. OFF

the key and turn it toward you. Your steering wheel will remain locked, just
as it was before you inserted the key.

ITICE:
If your key seems stuck in LOCK and you can’t turn it, be sure
it is all the
way in. If it is, then turn the steering wheel left and
right while you turn the key hard. But turn the key only with
your hand. Using
a tool to force it could break the key or the
ignition switch.
If none of this works, then your vehicle needs
service.
