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 GM 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 Inde-x.
~~ -
A CAUTION:
For up to two 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.
The air bag system does not need regular maintenance.
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 bag from working properly
in a crash.
Is there anything I might add to the front of the
vehicle that could keep the air bag from
working properly?
A: Yes. If you add things that change your vehicle's
frame. bumper system, front end sheet metal or
height, they may keep the air bag system from
working properly.
Also, the air bag system may not
work properly if you relocate any of the air bag
sensors.
If you have any question about this, you
should contact Customer Assistance before you
modify your vehicle.
(The phone numbers and
addresses for Customer Assistance are
in Step Two of
the Customer Satisfiction Procedure
in this manual.
See "Customer Satisfaction Procedure"
in the Index.)

I A CAUTION:
-
Leaving young children in a vehicle with the
ignition key is dangerous for many reasons.
A child or others could be badly injured or
even killed.
They could operate power windows or other
controls or even make the vehicle move. Don’t
leave the keys in a vehicle with young children.
2-2

This vehicle has one
double-sided key for the
ignition, endgate, spare tire
lock (two-door vehicles)
and door locks. It will fit
with either side up.
I 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 keys inside. You may even have to
damage your vehicle to get in.
So be sure you
have extra keys.
When a new vehicle is delivered, the dealer provides the owner with a pair
of identical keys and a key
code number.
The key code number tells your dealer
or a qualified
locksmith how to make extra keys. Keep this number
in
a safe place. If you lose your keys, you’ll be able to have
new ones made easily using
this number. Your selling
dealer should also have this number.

Theft
Vehicle theft is big business, especially in some cities.
Although
your vehicle has a number of theft-deter-rent
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.
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,
i1.s best to lock it up and take your keys.
But what if ~OLI have to leave your ignition key? What if
you have to leave something \duable in your vehicle?
0 Put your valuables in a storage area, like your
2 Olove box.
0 Lock all thc 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:
0 Keep your speed at 55 mph (88 km/h) or
less for the first
500 miles (805 km).
0 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.
See “Towing
a Trailer” in the Index for
more information.
0 Avoid making hard stops for the first
Don’t tow a trailer during break-in.
Ignition Positions
Use the key to turn the ignition switch to five different
positions.
C
I
ACCESSORY (A): ACCESSORY lets you use things
like the radio and the windshield wipers when the
engine
is off. Push in the key and turn it toward you.
Your steering wheel will remain locked. just as it was
before you inserted the key.
2-13

NOTICE:
Don’t operate accessories in the ACCESSORY
position for long periods of time. Prolonged
operation of accessories in the ACCESSORY
position could drain your battery and prevent
you from starting your vehicle.
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. Use OFF if you must have
your vehicle in motion while the engine is off (for
example, if your vehicle is being towed).
RUN (D): This is the position for driving.
START (E): This starts your engine.
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.
I NOTICE: I
If your key seems stuck in LOCK and you can’t
turn it, be sure you are using the correct key;
if
so, is it 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.
