Trunk
CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even death.
If you must drive with the trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on OUTSIDE AIR or with RECIRC turned
off. That will force outside air into your
vehicle. See ªComfort Controlsº in
the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
Trunk Lock Release
To unlock the trunk from the outside, insert the master
key and turn it.
Remote Trunk Release (Option)
If you have this option,
press the trunk release
button located in the glove
box to open the trunk lid.
The key does not have to be in the ignition for the
remote trunk button to work. The transaxle must be in
PARK (P) or NEUTRAL (N). The system also works
with the remote keyless entry system, if your vehicle has
this feature.

2-65
If the driver's belt is already buckled, the light will
come on briefly, but the chime will not sound.
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 ªAir
Bagº in the Index.
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.
CAUTION:
If the air bag readiness light stays on after 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 RUN. 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 optional DIC, a SERVICE AIR
BAG message will be displayed when there is a problem
with the air bag system. See ªDIC Warnings and
Messagesº in the Index for more information.

4-36 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 adjustment. If the trailer has
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.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.

4-37 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.

6-38 Front Turn Signals and Parking Lamps
1. Remove the two bolts with a 10 mm socket.
2. Use a large screwdriver by the outside mount to
separate the lamp assembly from the outboard snap
mounting pin. Slide the headlamp assembly outward
and lift it out.
3. Disconnect the wiring harness from the
headlamp assembly.

6-39
4. Tip the headlamp assembly and while pressing the
release, turn the bulb and socket counterclockwise to
remove them.
5. Replace the bulb and socket. Then reconnect the
wiring harness to the lamp assembly.6. Slide the lamp assembly back into place by lining up
the track on the bottom of the assembly with the
guide on the vehicle. Then connect the outboard snap
and secure the lamp assembly with the two bolts.

6-61 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 headlamp system checked
right away.
Windshield Wipers
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, be sure to have it fixed.
Power Windows and Other Power Options
Circuit breakers in the rear electrical center 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.
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.
If you ever have a problem on the road and don't have a
spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle that
you can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
The MaxiFuses are located in two Bussed Electrical
Centers (BEC), one located near the engine
compartment on the passenger's side and the other
under the rear seat on the driver's side. 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 BEC.
Snap the wide end of the fuse puller on to the fuse, at
the side indentations holding the puller and pull the
fuse out.
