The particles emitted during air bag inflation are not harmful to most
people. Some people with respiratory ailments may experience difficulty
breathing if they stay in the vehicle with the windows closed
after air bag
inflation.
So, if your air bag inflates, you and any passengers should exit the
vehicle if and when it is safe to do
so. If you or your passengers can’t get
out of the vehicle, try to get fresh air by opening a window, turning on the
fan, or opening a door.
Servicing Your Facial Air Bag-Equipped Vehicle
The facial 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 1994 GM Service Manual have information about
servicing your vehicle and the air bag system. The air bag system does not
need regular maintenance.
Safety Be/t Use During Pregnancy
Safety belts work for everyone, including pregnant women. Like all
occupants, they are more likely to be seriously injured if they don’t wear
safety belts.
A pregnant woman should wear a lapshoulder belt, and the lap portion
should be worn as low
as possible throughout the pregnancy.

You really should not park your vehicle, with a trailer attached, on a hill. If
something goes wrong, your rig could start to move. People can be injured.
and both your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into “P” (Park) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking brake, and shift to
5. Release the regular brakes.
“P” (Park).
When You Are Ready to Leave After Parking on a Hill
1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re pulling a trailer. See
the Maintenance Schedule for more on this. Thin.gs that are especially
important in trailer operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system, and brake
adjustment. Each of these
is covered in this manual, and the Index will help
you find them quickly. If you’re trailering, it’s a good idea to review these
sections before you start your trip.
Check periodically
to see that all hitch nuts and bolts are tight.
Trailer Light Wiring
See “Trailer Wiring Harness” in the Index.

your vehicle than
this manual can. To order the proper service manual, see
“Service Publications’’ in
the Index.
Your vehicle has a facial air bag system. Before attempting to do your own
service work, see “Servicing Your Facial Air Bag-Equipped Vehicle” in

can change the air cleaner filter without removing the engine cover. Just lift
the hood, unsnap both clips and remove
the top. After changing the filter,
snap both clips to secure
the air cleaner. Be sure air cleaner lid is correctly
positioned to seal out dust and contaminants that are harmful
to your engine.
Refer to the Maintenance Schedule to determine when to replace the air
filter.
See “Scheduled Maintenance Services”
in the Index.
NOTICE:
If the air cleaner is off, a backfire can cause a damaging engine
fire. And, dirt can easily get into your engine, which
will damage
it. Always have the air cleaner in place when you’re drivin\

Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid level is when the
engine oil is changed. Refer to the Maintenance Schedule to determine
when to change your fluid. See “Scheduled Maintenance Services” in the
Index.
How to Check
Because this operation can be a little difficult, you may choose to have this
done at a GM dealership Service Department.
If you do it yourself, be sure to follow all the instructions here,
or you could
get a false reading on the dipstick.

is in the
acceptable range,
push the dipstick
back in all the
way.
How to Add Fluid
Refer to the Maintenance Schedule to determine what kind of transmission
fluid to use. See “Recommended Fluids and Lubricants”
in the Index.
If the fluid level
is low, add only enough of the proper fluid to bring the
level up to the
COLD area for a cold check or the HOT area for a hot
check. It doesn’t take much fluid, generally less than
a pint. Don’t overfill.
We recommend you use only fluid labeled DEXRON@-I11 or
DEXRON@-IIE, because fluids with that label are made especially for our
automatic transmission. Damage caused by fluid other than DEXRON
-111
or DEXRON@-IIE is not covered by your new vehicle warranty.
d
After adding fluid, recheck the fluid level as described under “How to
Check.”
When the correct fluid level is obtained, push the dipstick back in all
the way.
