Lockout Protection
The power door locks will not work if the key is in the
ignition and any door is open. You can override this
feature by holding the driver’s power door lock switch
for more than three seconds.
Leaving Your Vehicle
If you are leaving the vehicle, take your keys, open your
door and set the locks from the inside. Then get out
and close the door. Or, press the lock button on
the remote keyless entry transmitter after shutting the
doors.
If your vehicle has a theft-deterrent system, see
Universal Theft-Deterrent on page 2- 19.
Trunk
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.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. 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.
This light will come on
when you start your
vehicle, and it will flash for
several 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 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
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 the
DIC an AIR BAG PROBLEM message will be
displayed when there is a problem with the air bag
system. See
DIC Warnings and Messages on page 3-50
for more information.

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 vehicle’s 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
in the rear corner of the 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.
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.
4-40
ProCarManuals.com

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. 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.

Electrical System
Add-on Electrical Equipment
Nofice: 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 1-54.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the wiring harness. An electrical overload will cause
the lamps to go on and
off, or in some cases to remain
cff. if this hqppns, hawe p1r headlamp system
checked 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 fuse panel 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.
5-91
ProCarManuals.com

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 fires
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 a MaxiFuse@ should blow, see your
dealer for service immediately.
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. 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. You will find a fuse puller
clipped in both
of the fuse blocks. Snap the wide end
of the fuse puller at the side indentations and pull
the fuse out.
The MaxiFuses@ are located in two fuse blocks, one
located in the engine compartment and the other under
the rear seat. If a MaxiFuse@ should blow, have your
vehicle serviced by your dealer immediately.
Engine Compartment Fuse Block
The engine compartment
fuse block is located near
the front on the
Comparfment Oiewiew on
page 5-14 for more
information on location.
Lift the cover to gain access. Fuse
22 or 23 can be
moved
to the outer position to provide continuous power
to the accessory power outlet or cigarette lighter
when the ignition is not on. See your dealer for
additional assistance,
if needed.
Leaving an accessory on for a long period of time can
drain the vehicle’s battery.
