Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height,
front end or side sheet metal, they may keep
the airbag system from working properly.
Also, the airbag system may not work properly
if you relocate any of the airbag 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. SeeCustomer
Satisfaction Procedure on page 412.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel,
instrument panel, ceiling headliner, ceiling and
pillar garnish trim, roof-mounted airbag
modules, or airbag wiring can affect the
operation of the airbag system. If you have
questions, call Customer Assistance. The
phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual.
SeeCustomer Satisfaction Procedure on
page 412.

{CAUTION:
It can be dangerous to drive with the
liftgate open because carbon monoxide
(CO) gas can come into your vehicle. You
cannot see or smell CO. It can cause
unconsciousness and even death. If you
must drive with the liftgate open or if
electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
and select the control setting that will
force outside air into your vehicle. See
Climate Control System on page 170.
If you have air outlets on or under the
instrument panel, open them all the
way. SeeEngine Exhaust on page 132.
Manual Liftgate Release
If the liftgate cannot be opened by pressing the
switch on the outside handle, the battery may
be run down. SeeJump Starting on page 320.
To manually open the liftgate, do the following:
1. Remove the trim plug, located on the inside of
the liftgate near the center.

Airbag Readiness Light
There is an airbag readiness light on the
instrument panel, which shows the airbag symbol.
The system checks the airbag’s electrical
system for malfunctions. The light tells you if there
is an electrical problem. The system check
includes the airbag sensor, the airbag modules,
the wiring and the crash sensing and diagnostic
module. For more information on the airbag
system, seeAirbag System on page 71.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go
out. This means the
system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
The airbag readiness light should ash for a few
seconds when you turn the ignition key to RUN or
START. If the light does not come on then,
have it xed so it will be ready to warn you if there
is a problem.

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 are turning with a trailer, make wider
turns than normal. Do this so your trailer will
not 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 asher and/or extra wiring.
Check with your dealer. The arrows on your
instrument panel will ash whenever you signal a
turn or lane change. Properly hooked up, the
trailer lamps will also ash, telling other drivers you
are about to turn, change lanes or stop.When towing a trailer, the arrows on your
instrument panel will ash 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 is important to check
occasionally to be sure the trailer bulbs are still
working.
Driving on Grades
Notice:Do not tow on steep continuous
grades exceeding 6 miles (9.6 km). Extended,
higher than normal engine and transaxle
temperatures may result and damage your
vehicle. Frequent stops are very important to
allow the engine and transaxle to cool.
When towing under severe conditions such as hot
ambient temperatures or steep grades, your
vehicle may experience more transaxle shifting.
A COOLING MODE ON message may also appear
in the DIC.This alerts the driver that the shifting
mode is in progress and is aiding engine cooling.
SeeDIC Warnings and Messages on page 197

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 88.
Headlamp Wiring
The headlamp wiring is protected by fuses. Should
your headlamps fail to function, have your
headlamp system checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a
circuit breaker and a fuse. If the motor overheats
due to heavy snow or ice, the wiper will stop
until the motor cools. If the overload is caused by
some electrical problem, have it xed.
Power Windows and Other Power
Options
Fuses in the fuse block protect the power windows.
When the current load is too heavy, the fuse opens
protecting the circuit until the problem is xed.
380

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses,
circuit breakers and fusible thermal links.
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 do not
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.
There are two fuse blocks in your vehicle: the oor
console fuse block and the engine compartment
fuse block.
There are also one or two fuses located at the
back of the vehicle near the battery.
Floor Console Fuse Block
The oor console fuse block is located on the
passenger’s side of the oor console behind the
forward panel. The panel has four clips, one in
each corner. Pull the panel to disconnect the four
clips, and access the fuses. Use the fuse puller to
remove fuses.
