The air bag is designed to inflate only once. After it inflates, you’ll
need some new parts for your air bag system. If you don’t get them, the
air bag system won’t be there to help protect
you in another crash. A
new system will include the air bag module and possibly other parts.
The service manual for your vehicle covers the need
to replace other
parts.
Your vehicle is equipped with a diagnostic module, which records
information about the air bag system. The module records information
about the readiness
of the system, when the sensors are activated and
driver’s safety belt usage at deployment.
Let only qualified technicians work on your air bag system. Improper
service can mean that your air bag system won’t work properly. See
your dealer for service.
I 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.

Adding Equipment to Your Air Bag-Equipped Vehicle
Q: IfI add a push bumper or a bicycle rack to the front of my vehicle,
A: As long as the push bumper or bicycle rack is attached to your vehicle
will it keep the air bag from working properly?
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 snow 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.
Q: Is there anything I might add to the front of the vehicle that could
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 Satisfaction
Procedure in this manual. See “Customer Satisfaction Procedure”

Safety Belt Reminder Light
When the key is turned to RUN or START, a tone will come on for about
eight seconds to remind people to fasten their safety belts, unless the
driver’s safety belt is already buckled. The safety belt light will also come
on and stay on for about 20 seconds, then it will flash for about 55 seconds.
If the driver’s belt is already buckled, neither the tone nor the light will
come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument panel, which shows
AIR BAG. The system checks the air bag’s electrical system for
malfunctions. The light tells you
if there is an electrical problem. The
system check includes the air bag sensors and module, the wiring and the
diagnostic module. For more information
on the air bag system, see “Air
Bag” in the Index.

Fuels in Foreign Countries (Gasoline
Engines)
If you plan on driving in another country outside the U.S. or Canada,
unleaded
fuel may be hard to find. Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled, the exhaust system can corrode,
and your engine oil can deteriorate quickly. Your vehicle’s oxygen sensor
will be damaged. All of that means costly repairs that wouldn’t be covered
by your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company that does business
in the country where you’ll be driving.
You can
also write us at the following address for advice. Just tell us where
you’re going and give your Vehicle Identification Number
(VIN).

Filling Your Tank
The fuel cap is behind
a hinged door on the
left side of your
vehicle.
A CAUTION:
Gasoline vapor is highly flammable. It burns violently, and that
can cause very bad injuries. Don’t smoke if you’re near gasol\
ine
or refueling your vehicle.
Keep sparks, flames, and smoking
materials away from gasoline.

Engine Control Module System
Gasoline Engines
This system has an oxygen sensor (OS) that helps keep your engine’s
air-fuel mixture at a proper
level. Use only unleaded fuel in your vehicle. If
you use leaded fuel, you could damage your oxygen sensor (OS) and
three-way catalytic converter.
Diesel Vehicles Below 8,500 (3 850 Kg) GVWR
This system monitors engine speed and throttle position. It adjusts exhaust
gas recirculation to limit emissions.
Malfunction Indicator (SERVICE ENGINE SOON)
Light
The Malfunction Indicator (SERVICE ENGINE SOON) Light on your
instrument panel lets you know when your emission system needs service.
The light will come on briefly
when you start your engine to let you know
that the system is working.
If it does not come on when you start your
engine, or if
it comes on and stays on while you’re driving, your system
may need service. Your vehicle should still be driveable, but
you should
have your system serviced right away.
Secondary Air Injection Reaction (AIR) System
(Gasoline Engines)
You may have this system. It has a control valve that will direct air to where
it is needed. If the AIR system needs service, your Malfunction Indicator
(SERVICE ENGINE
SOON) Lamp on your instrument panel will come on.
Tires
We don’t make tires. Your new vehicle comes with high-quality tires made
by
a leading tire manufacturer. These tires are warranted by the tire
manufacturers, and their warranties are delivered with every new vehicle.
If
your spare tire is a different brand than your road tires, you will have a tire
warranty folder from each
of these manufacturers.
