1-36 Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the
air bag systems. To purchase a service manual, see
ªService and Owner Publicationsº in the Index.
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 yellow connectors. They
are probably part of the air bag systems. Be sure
to follow proper service procedures, and make
sure the person performing work for you is
qualified to do so.
The air bag systems do not need regular maintenance.
Adding Equipment to Your
Air Bag-Equipped Vehicle
Q:If I add a push bumper or bicycle rack to the
front of my vehicle, will it keep the air bags
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 bags from working properly in a crash.
Q:Is there anything I might add to the front or
sides of the vehicle that could keep the air bags
from working properly?
A:Yes. If you add things that change your vehicle's
frame, bumper system, front end or side 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 questions 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 ªCustomer Satisfaction Procedureº
in the Index.

2-59 Accessory Power Outlets
Two accessory power outlets are located near the
cigarette lighter. Use these outlets to power mobile
telephones or other devices designed to operate with
vehicle electrical systems.
The cigarette lighter is designed to fit only in the
receptacle to the right of the accessory power outlets.
Power outlets are also located in the rear cargo area on
the passenger side and in the rear of the center floor
compartment (if equipped with rear seat audio). To use
the outlets, remove the cover by lifting the pull tab.When not in use, always cover the rear outlet with the
protective cap.
Certain accessory power plugs may not be compatible to
the accessory power outlets and could result in blown
vehicle or adapter fuses. If you experience a problem,
see your dealer for additional information on the
accessory power outlets.
Sun Visors
To block out glare, you can swing down the top and bottom
visors (if equipped). You can also swing the bottom visor
from side
-to-side. Your visors may have an extension that
can be pulled out for additional glare protection.
Illuminated Visor Vanity Mirror
(If Equipped)
Pull the sun visor down and lift the mirror cover to turn
on the lamps. There is a slide switch to adjust the
intensity of the lamps.

3-28 Rear Seat Audio (If Equipped)
This feature allows rear seat passengers to listen to any
of the music sources including AM
-FM, automatic tone
control, cassette tapes and CDs. However, the rear seat
passengers can only control the music sources that the
front seat passengers are not listening to. For example,
rear seat passengers may listen to a cassette tape through
headphones while the driver listens to the radio through
the front speakers. The rear seat passengers have control
of the volume for each set of headphones. Be aware that
the front seat audio controls always override the rear
seat audio controls.
This feature is intended for rear seat passengers.PWR: Press this button to turn the rear seat audio
system on or off. The rear speakers will be muted when
the power is turned on. You may operate the rear seat
audio functions even when the primary radio power
is off.
VOL: Press this knob lightly so it extends. Turn the
knob clockwise to increase volume and counterclockwise
to decrease volume. Push the knob back into its stored
position when you're not using it. The upper VOL knob
controls the upper headphone and the lower VOL knob
controls the lower headphone.
AM
-FM: Press this button to switch between AM, FM1
and FM2. If the front passengers are already listening to
AM
-FM, the rear seat audio controller will not switch
between the bands and cannot change the frequency.
SEEK: While listening to AM
-FM, press the up arrow
to tune to the next higher station and stay there. Press
the down arrow to tune to the next lower station and
stay there. The sound will mute while seeking. The
SEEK button is inactive if the AM
-FM mode on
the front radio is in use.
While listening to a cassette tape, press the up arrow to
hear the next selection on the tape. Press the down arrow
to go back to the previous selection. The SEEK button is
inactive if the tape mode on the front radio is in use.

3-33 Understanding Radio Reception
AM
The range for most AM stations is greater than for
FM, especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to come and go.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until it is too late. Your hearing can adapt to higher
volumes of sound. Sound that seems normal can be
loud and harmful to your hearing. Take precautions
by adjusting the volume control on your radio to a
safe sound level before your hearing adapts to it.To help avoid hearing loss or damage:

Adjust the volume control to the lowest setting.

Increase volume slowly until you hear comfortably
and clearly.
NOTICE:
Before you add any sound equipment to your
vehicle
-- like a tape player, CB radio, mobile
telephone or two
-way radio -- 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, Delphi Delco Electronics
radio or other systems, and even damage them.
Your vehicle's systems may interfere with the
operation of sound equipment that has been
added improperly.
So, before adding sound equipment, check with
your dealer and be sure to check Federal rules
covering mobile radio and telephone units.

Defensive Driving
The best advice anyone can give about driving is:
Drive defensively.
Please start with a very important safety device in your
vehicle: Buckle up. See ªSafety Beltsº in the Index.Defensive driving really means ªbe ready for anything.º
On city streets, rural roads or freeways, it means
ªalways expect the unexpected.º
Assume that pedestrians or other drivers are going to be
careless and make mistakes. Anticipate what they might
do. Be ready for their mistakes.
Rear
-end collisions are about the most preventable
of accidents. Yet they are common. Allow enough
following distance. It's the best defensive driving
maneuver, in both city and rural driving. You never
know when the vehicle in front of you is going to
brake or turn suddenly.
Defensive driving requires that a driver concentrate
on the driving task. Anything that distracts from the
driving task
-- such as concentrating on a cellular
telephone call, reading, or reaching for something on
the floor
-- makes proper defensive driving more
difficult and can even cause a collision, with resulting
injury. Ask a passenger to help do things like this, or
pull off the road in a safe place to do them yourself.
These simple defensive driving techniques could save
your life.

4-34
Hydroplaning doesn't happen often. But it can if your
tires do not have much tread or if the pressure in one or
more is low. It can happen if a lot of water is standing on
the road. If you can see reflections from trees, telephone
poles or other vehicles, and raindrops ªdimpleº the
water's surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds.
There just isn't a hard and fast rule about hydroplaning.
The best advice is to slow down when it is raining.
Driving Through Deep Standing Water
NOTICE:
If you drive too quickly through deep puddles
or standing water, water can come in through
your engine's air intake and badly damage your
engine. Never drive through water that is slightly
lower than the underbody of your vehicle. If you
can't avoid deep puddles or standing water, drive
through them very slowly.
Driving Through Flowing Water
CAUTION:
Flowing or rushing water creates strong forces.
If you try to drive through flowing water, as you
might at a low water crossing, your vehicle can
be carried away. As little as six inches of flowing
water can carry away a smaller vehicle. If this
happens, you and the other vehicle occupants
could drown. Don't ignore police warning signs,
and otherwise be very cautious about trying to
drive through flowing water.
Some Other Rainy Weather Tips

Turn on your low-beam headlamps -- not just your
parking lamps
-- to help make you more visible to others.

Besides slowing down, allow some extra following
distance. And be especially careful when you pass
another vehicle. Allow yourself more clear room
ahead, and be prepared to have your view restricted
by road spray.

Have good tires with proper tread depth. See ªTiresº
in the Index.
