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, the air bag modules,
the wiring and the crash sensing and diagnostic
module. For more information on the air bag system,
see
Air Bag Systems on page 1-47.
AIR
BAG
This light will come on
when you start your
vehicle, and it will flash for
a few seconds. Then
the light should go out.
This means the system is
ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away. If the air

you
start your vehicle,
it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate
in a crash, or they
could even inflate without a crash.
To help
avoid injury
to yourself or others, have your
vehicle serviced right away if the air bag
readiness
light stays on after you start your
vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to
ON. If the
light doesn’t come
on then, have it fixed so it will
be ready to warn you if there is a problem.
On vehicles with the
DIC, a SERVICE AIR BAG
message will be displayed when there is a problem with
the air bag system. See
DIC Warnings and Messages
on page 3-60 for more information.

Will you have to make any holes in the body of
your vehicle when you install a trailer hitch?
If
you do, then be sure to seal the holes later when
you remove the hitch.
If you don’t seal them, deadly
carbon monoxide (CO) from your exhaust can get
into your vehicle. See
Engine Exhaust on
page 2-36. Dirt and water can also enter the
vehicle.
Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the
tongue of the trailer
so that the tongue will not drop to
the road
if it becomes separated from the hitch.
Instructions about safety chains may be provided by the
hitch manufacturer or by the trailer manufacturer.
Follow the manufacturer’s recommendation for attaching
safety chains and do not attach them to the bumper.
Always leave just enough slack
so you can turn
with your rig. And, never allow safety chains to drag on
the ground.
Trailer Brakes
Does your trailer have its own brakes? Be sure to read
and follow the instructions for the trailer brakes
so
you’ll be able to install, adjust and maintain them
properly. Because you have
anti-lock brakes, do not try to tap
into your vehicles brake system.
If you do, both
brake systems won’t work well, or at all.
Trailer Wiring Harness
All of the electrical circuits required for your trailer
lighting system can be accessed at the driver’s side rear
lamp connector. This connector is located under the
carpet on the rear corner of your trunk compartment.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror aajustment.
ii tne rraiier nas
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be
sure the brakes are working. This lets you check your
electrical connection at the same time.
Oiiriiig your trip, check occasicfially tc be sure that the
load is secure, and that the lamps and any trailer
brakes are still working.
4-39

Following Distance
Stay at least twice as far behind the vehicle ahead as
you would when driving your vehicle without a trailer.
This can help you avoid situations that require
heavy braking and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer, you’ll need to go much farther beyond the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and,
if possible,
have someone guide you.
Making Turns
Notice: Making very sharp turns while trailering
could cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns
than normal.
Do this so your trailer won’t strike
soft shoulders, curbs, road signs, trees or other objects.
Avoid jerky or sudden maneuvers. Signal well
in
advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your dealer. All of the electrical circuits required for
your trailer lighting system can be accessed at the
left rear lamp connector. This connector is located under
the carpet on the driver’s side in the rear corner of
your trunk compartment. The arrows on your instrument
panel will flash whenever you signal a turn or lane
change. Properly hooked up, the trailer lamps will also
flash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even
if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Your vehicle has bulb warning lights. When you plug a
trailer lighting system into your vehicle’s lighting
system, its bulb warning lights may not let you know
if
one of your lamps goes out. So, when you have a trailer
lighting system plugged in, be sure to check your
vehicle and trailer lamps from time to time to be sure
they’re all working. Once you disconnect the trailer
lamps, the bulb warning lights again can tell you
if one
of your vehicle lamps is out.

Electrical System
Add-on Electrical Equipment
Notice: Don’t add anything electrical to your
vehicle unless you check with your dealer first.
Some electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment can keep other components from working as they
should.
Your vehicle has an air bag system. Before attempting
to add anything electrical to your vehicle, see
Servicing Your Air Bag-Equipped Vehicle on page 1-55.
Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker. An electrical overload will cause the lamps
to go on and
off , or in some cases to remain off. If this
happens, have your neaaiamp system cneckea
right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker and a fuse.
If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools.
If the overload is caused by some electrical
problem, have it fixed.
Power Windows and Other Power
Options
Circuit breakers in the rear fuse block protect the power
windows and other power accessories. When the
current load is too heavy, the circuit breaker opens and
closes, protecting the circuit until the problem
is fixed
or goes away.
5-91

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of damage
caused by electrical problems.
Look at the silver-colored band inside the fuse.
If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
The MaxiFuses are located in
two fuse blocks, one in
the engine compartment and the other under the
rear seat. If a MaxiFuse should blow, have your vehicle
serviced by your dealer immediately.
Removing Fuses
You will find a fuse puller attached in both of the fuse
blocks. Snap the wide end of the fuse puller on
to
the fuse, at the side indentations holding the puller and
pull the fuse
out.
Engine Compartment Fuse Block
The engine compartment
fuse block is located in the
front
of the engine
compartment on the
passenger’s side. Lift the
cover
to gain access.
Fuse
22 or 23 can be moved to the outer position to
enable the accessory power outlet or cigarette lighter
when the ignition is not on. See your dealer for
additional assistance,
if needed.
