1997 GMC SIERRA steering

The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it’s more
likely that the fetus won’t be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
Right Front Passenger Position
The right front passenger’s safety belt works the same
way as the driver’s safety belt. See “Driver Position”
earlier in this section.
Wheri the lap belt is pulled out all the way, it will lock.
(This is the child restraint locking feature working
normally.) If the belt locks, let it
go back all the way
and start again.
Supplemental Inflatable
Restraint System
This part explains the Supplemental Inflatable Restraint
system or air bag system.
Your vehicle may have an
air bag for the driver and
another air bag for the
right front passenger. If
it does, it will say
Supplemental Inflatable
Restraint
on the middle
part of the steering wheel.

There is an air bag
readiness light on the
AIR
BAG
instrument panel, which
shows AIR
BAG.
The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See “Air Bag Readiness Light”
in the Index
for more information.
How the Air Bag System Works
Where are the air bags?
The driver’s air bag is in the middle of the
steering wheel.
ProCarManuals.com

The right front passenger’s air bag is in the instrument
panel on the passenger’s side.
A CAUTION:
If something is between an occupant and an air
bag, the bag might not inflate properly or it
might force the object into that person. The path
of an inflating
air bag must be kept clear. Don’t
put anything between an occupant and an air
bag, and don’t attach or put anything
on the .
steering wheel hub or on or near any other air
bag covering.

When should an air bag inflate?
An air bag is designed to inflate in a moderate to severe
frontal or near-frontal crash. The air bag will inflate
only
if the impact speed is above the system’s designed
“threshold level.”
If your vehicle goes straight into a
wall that doesn’t move or deform, the threshold level
is
about 9 to 16 mph (14 to 26 km/h). The threshold level
can vary, however,
with specific vehicle design, so that
it can be somewhat above or below this range. If your
vehicle strikes something that will move or deform, such
as
a parked car, the threshold level will be higher. The
air bag is not designed to inflate in rollovers, side
impacts or rear impacts, because inflation would not
help
the occupant.
In any particular crash, no one can say whether an air
bag should have inflated simply because of the damage
to
a vehicle or because of what the repair costs were.
Inflation
is determined by the angle of the impact and
how quickly the vehicle slows down
in frontal or
near-frontal impacts. The air
bag system
is designed to work properly under
a wide range
of conditions, including off-road usage.
Observe safe driving speeds, especially on rough terrain.
As always, wear your safety belt. See “Off-Road
Driving”
in the Index for more tips on off-road driving.
What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle
is in a crash. The sensing
system triggers a release
of gas from the inflator, which
inflates the air bag. The inflator, air bag and related
hardware are all part of the air bag modules inside the
steering wheel and
in the instrument panel in front of
the right front passenger.

How does an air bag restrain?
In moderate to severe frontal or near-frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. Air bags supplement the
protection provided by safety belts. Air bags distribute
the force
of the impact more evenly over the occupant’s
upper body, stopping
the occupant more gradually. But
air bags would not help you in many types of collisions,
including rollovers, rear impacts and side impacts,
primarily because an occupant’s motion
is not toward
those air bags. Air bags should never be regarded
as anything more than a supplement to safety belts,
and then only
in moderate to severe frontal or
near-frontal collisions.
What will you see after an air bag inflates?
After an
air bag inflates, it quickly deflates, so
quickly that some people may not even realize the
air bag inflated. Some components
of the air bag
module
-- the steering wheel hub for the driver’s air bag,
or the instrument panel for the right front passenger’s
bag
-- will be hot for a short time. The parts of the bag
that come into contact with you may be warm, but not
too hot to touch. There will be some smoke and dust
coming from vents in the deflated air bags. Air bag
inflation doesn’t prevent the driver from seeing or from
being able to steer the vehicle, nor does it stop people
from leaving the vehicle.
A CAUTION:
When an air bag inflates, there is dust in the air.
This dust could cause breathing problems for
people with a history
of asthma or other
breathing trouble. To avoid this, everyone in the
vehicle should get
out as soon as it is safe to do so.
If you have breathing problems but can’t get out
of the vehicle after an air bag inflates, then get
fresh air
by opening a window or door.

, Let only qualified technicians work on your air
I bag system. Improper service can mean that your
air bag system won’t work properly. See your dealer
for service.
NOTICE:
If you damage the covering for the driver’s or the
right front passenger’s
air bag, the bag may not
work properly. You
may have to replace the air
bag module in the steering wheel or both the air
~ bag module and the instrument panel for the
I passenger’s air bag. Do not open or break the air
bag coverings.
Servicing Your Air Bag-Equipped Vehicle
Air bags affect 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 service manual have information
about servicing your vehicle and the air bag system. To
purchase
a service manual, see “Service and Owner
Publications’’ in the Index.
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate uring improper service. You
can be injured
if yo 6 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.
The air bag system does not need regular maintenance.

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.
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.
Parking Lots
If you park in a lot where someone will be watching
your vehicle, it’s best 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 (805 km).
Don’t drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don’t make full-throttle starts.
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.
0 Don’t tow a trailer during break-in. See
“Towing a Trailer’’ in the Index for
more information.
a Avoid making hard stops for the first

Ignition Positions
You can use your key to turn your ignition switch to five
different positions.
A E
ACCESSORY (A): ACCESSORY lets you use things
like the radio, power windows and the windshield
wipers when the engine
is off. Push in the key and turn
it towards you. Your steering wheel will remain locked,
just as it was before you inserted the key.
LOCK (B): This position locks your ignition, steering
wheel and transmission. It’s
a theft-deterrent feature.
You will only be able to remove your key when the
ignition is turned to
LOCK.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. It doesn’t lock the steering
wheel like
LOCK. Use OFF if you must have your
vehicle
in motion while the engine is off (for example,
your vehicle
is being pushed).
RUN (D): This is the position for driving.
START (E): This starts your engine.
I-
-
I A CAUTIO1.;
if
On manual transmission vehicles, turning the key
to
LOCK will lock the steering column and result
in
a loss of ability to steer the vehicle. This could
cause
a collision. If you need to turn the engine
off while the vehicle is moving, turn the key only
to
OFF. Don’t press the key release button while
the vehicle is moving.
