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 AUTO or ECON and the temperature
between 65 F (18 C) and 85 F (29 C).
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 use this feature, your
vehicle must be in PARK (P)
or NEUTRAL (N) and the
VALET lockout switch must
be off.
Press the trunk release button, located on the left side of
the instrument panel, to open the trunk.
You can also press the trunk button on the remote
keyless entry transmitter to access the trunk
compartment. To disable the use of this feature, see
ªValet Lockout Switchº in the Index.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG or the symbol of an 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.
United States Canada
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 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.

4-39 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
Because you have anti-lock brakes, don't try to tap into
your vehicle's hydraulic brake system. If you do, both
brake systems won't work well, or at all. If you tow
more than 1,000 lbs. (450 kg), use trailer brakes. Be sure
to follow the instructions that come with the trailer or
from the brake manufacturer.
Be sure to read and follow the instructions for the trailer
brakes so you'll be able to maintain them properly.
Trailer Wiring Harness (Option)
If your vehicle is equipped with the trailer towing
package, your vehicle has additional wiring to attach
to a trailer's wiring harness. Contact your dealer for
proper installation.

4-41 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.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don't shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
For some grade conditions, it may be better to drive in
THIRD (3) to lessen transaxle shifting. You may wish to
drive in THIRD (3) instead of DRIVE (D) while towing
a trailer.
On a long uphill grade, reduce your speed to around
45 mph (70 km/h) or less to reduce the possibility of
engine and transaxle overheating.

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 ªServicing
Your Air Bag
-Equipped Vehicleº in the Index.
Headlamp Wiring
The headlamp wiring system has four individual fuses,
LF low, RF low, LF high and RF high. An electrical
overload will cause the lamps to go on and off, or in
some cases to remain off. If this happens, have the
headlamp wiring checked right away.
Windshield Wiper Fuses
A circuit breaker protects the wiper motor. If the wiper
motor overheats due to heavy snow, the wipers will stop
until the motor cools and will then restart.
A MiniFuse

powers the wiper motor. If the MiniFuse
blows, there is an electrical problem. Be sure to have
it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and power
seats. When the current load is too heavy, the circuit
breaker opens and closes, protecting the circuit until the
problem is fixed or goes away.

6-64 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 ªborrowº 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.
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.Underhood Junction BlockThe front Bussed Electrical Center (BEC) is located
next to the engine on the passenger's side of the vehicle.
To access the fuse block, push in the two tabs located on
the top and the bottom of the fuse block cover.
