in rollover, rear, side or low-speed frontal crashes.
Everyone in your vehicle should wear a safety belt
properly
-- whether or not there’s an air bag for
that person.
A CAUTION:
Air bags inflate with great force, faster than the
blink of an eye.
If you’re too close to an inflating
air bag, it could seriously injure you. Safety belts
help keep you in position before and during a
crash. Always wear your safety belt, even with an
air
bag, and sit as far back as you can while still
maintaining control
of your vehicle. There is
an air bag readiness
light on
the instrument
panel, which shows
AIR
BAG
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.

will light up when you shift
into four-wheel drive. A
slight delay between shifting and the pattern’s lighting is
normal. If the pattern does not light up, or if the front
axle lights do not go out after you shift out of
four-wheel drive, have your dealer check your system.

highway situations. Your front axle is
not engaged in
two-wheel drive.
4HI: This setting engages your front axle to help
drive
your vehicle. Use 4HI when you need extra
traction, such as on snowy
or icy roads, or in most
off-road situations.
N SET PARK BRAKE: Shift to this neutral setting
only when your vehicle needs to be towed.
4LO: This setting also engages your front axle to give
you extra traction and provides extra gear reduction.
You may never need 4LO. It sends the maximum power
to all four wheels. You might choose 4LO if you were
driving off-road in sand, mud or deep snow and
climbing or descending steep hills.
You can shift from 2HI to 4HI or from 4HI to 2HI while
the vehicle is moving. Do not press the transfer case
shift lever button when shifting from 2HI
to 4HI or

your warning lights and gages could also save you
or
others from injury.

follow the previous steps. and drive the vehicle
to your
dealer
or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently
put fuel into your vehicle'?
If so, reinstall the fuel cap. making sure to fully install
the cap. The diagnostic system can determine
if the fuel cap
has been left off
or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed should turn the light off.
Did you just drive through a deep puddle of water'?
If so. your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Have you recently changed brands of fuel?
If so. be sure to fuel your vehicle with quality fuel (see
"Fuel"
in the Index). Poor fuel quality will cause your
engine not
to run as efficiently as designed. You may
notice
this as stalling after start-up. stalling when you put
the vehicle into gear, misfiring, hesitation on acceleration
or stumbling
on acceleration. (These conditions may go
away once the engine is warmed up.) This will be detected
by the system and cause the light to turn on.
If you experience one or more of these conditions.
change the fuel brand
you use. It will require at least one
full tank of the proper fuel to turn the light off.
tr none of the above steps have made the light turn off,
have your ciealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic
tools to fix any mechanical or electrical
problems
that may have developed.

-- be sure you can add
what you want.
If you can, it’s very important to do
it properly. Added
sound equipment may interfere
with the operation
of your vehicle’s engine, Delco

Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or
a damaged
mechanism. Cassette tapes should be stored
in their
cases away from contaminants, direct sunlight and
extreme heat.
If they aren’t, they may not operate
properly or may cause failure
of the tape player.
Your tape player
should be cleaned regularly after every
50 hours of use. If you notice a reduction in sound
quality, try a known good cassette to see if
it is the tape
or the tape player
at fault. If this other cassette has no
improvement
in sound quality, clean the tape player.
Cleaning may be done with a scrubbing action,
non-abrasive cleaning cassette
with pads which scrub
the tape head
as the hubs of the cleaner cassette turn. It
is normal for the cassette to eject while cleaning. Insert
the cassette at least three times to ensure thorough
cleaning.
A scrubbing action cleaning cassette is
available through your GM dealership.
