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.
Q:What if I add a snow plow? Will it keep the air
bags 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 ªtripping mechanism.º If you do,
it can damage your snow plow and your vehicle,
and it may cause an air bag inflation.

Accessory Power Outlets
With accessory power outlets you can plug in auxiliary

Two accessory power outlets are located near the
cigarette lighter. The cigarette lighter is designed to
fit only in the receptacle to the right of the accessory
power outlets.
To use the outlets, lift the cover. When not using them,
always close the cover.
Certain power accessory 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 plugs.
NOTICE:
Adding some electrical equipment to your vehicle
can damage it or keep other things from working
as they should. This wouldn't be covered by your
warranty. Check with your dealer before adding
electrical equipment, and never use anything that
exceeds the fuse rating.
When adding electrical equipment, be sure to follow
the proper installation instructions included with
the equipment.
NOTICE:
Power outlets are designed for accessory plugs
only. Do not hang any type of accessory or
accessory bracket from the plug. Improper use of
the power outlet can cause damage not covered
by your warranty.

Compact Disc Messages
ERR (Error): If this message appears and the disc
comes out, it could be for one of the following reasons:

If you're driving on a very rough road. When the
road becomes smooth the disc should play.

If it's very hot. When the temperature returns to
normal, the disc should play.

The disc is upside down.

It is dirty, scratched or wet.

The air is very humid. (If so, wait about an hour and
try again.)

If the CD is not playing correctly, for any other
reason, try a known good CD.
Press RECALL to make ERR go off of the display.
If any error occurs repeatedly or if an error can't be
corrected, contact your dealer.Rear Seat Audio (If Equipped)
This feature allows rear seat passengers to listen to any
of the music sources: AM
-FM, 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 CD 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.

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 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.
Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling
discs. Pick up discs by grasping the outer edges or the
edge of the hole and the outer edge.
Care of Your Compact Disc Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics with
lubricants internal to the CD mechanism.
Cleaning Your Remote Cassette Tape Player
Your remote tape player should be cleaned regularly
after every 50 hours of use. Your radio may display
CLN to indicate that you have used your remote
cassette tape player for 50 hours without resetting the
tape clean timer. If this message appears on the display,
your remote cassette player needs to be cleaned. It will
still play tapes, but you should clean it as soon as
possible to prevent damage to your tapes and player.

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.

4-38
Driving too fast through large water puddles or even
going through some car washes can cause problems, too.
The water may affect your brakes. Try to avoid puddles.
But if you can't, try to slow down before you hit them.
CAUTION:
Wet brakes can cause accidents. They won't work
as well in a quick stop and may cause pulling to
one side. You could lose control of the vehicle.
After driving through a large puddle of water or
a car wash, apply your brake pedal lightly until
your brakes work normally.
Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen if the road is wet enough and you're
going fast enough. When your vehicle is hydroplaning,
it has little or no contact with the road.
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.
