Canceling the Rear Door Security
Locks
1. Unlock and open the rear door from the outside.
2. Push the lever down to disengage the safety lock.
3. Close the door.
4. Repeat Steps 1 through 3 for the other rear
door lock.
The rear door locks will now work normally.
Lockout Protection
The lockout protection feature may prevent you from
locking your key in your vehicle. Pressing the power
door lock switch will lock all doors, then unlock
the driver’s door, if the key is in the ignition when a
door is opened.
If you leave the key in your vehicle but not in the
ignition or if you use the manual door lock, you could
still lock the key in the vehicle. Always remember to
take the key with you.
Liftgate
{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. SeeClimate Control
System on page 3-28.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-29.
2-11

If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when you
signal a turn, check for burned-out bulbs and check the
fuse. SeeFuses and Circuit Breakers on page 5-101.
If you have a trailer towing option with added wiring for
the trailer lamps, the signal indicator will ash at a
normal rate even if a turn signal bulb is burned out.
Check the front and rear turn signal lamps regularly to
make sure they are working.
Turn Signal On Chime
If either turn signal is left on for more than 3/4 mile
(1.2 km), a chime will sound to let the driver know to
turn it off.
If you need to leave the signal on for more than
3/4 mile (1.2 km), turn off the signal and then turn it
back on.
Headlamp High/Low-Beam Changer
To change the headlamps from low to high, push
the turn signal lever away from you, then release it.
To change the headlamps from high to low, pull the
lever toward you.
When the high beams
are on, this light on the
instrument panel cluster
and the HUD display
(if equipped), will also
be on.
Flash-to-Pass
When the headlamps are off, pull the lever toward you
to momentarily turn on the high beams. This will
signal that you are going to pass. When you release
the lever, they will turn off.

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, diagnostic module, and safety
belt pretensioners. For more information on the airbag
system, seeAirbag System on page 1-72. For more
information on safety belt pretensioners, seeSafety Belt
Pretensioners on page 1-45.
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 or safety belt pretensioners 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 ON. If the
light does not come on then, have it xed so it will
be ready to warn you if there is a problem.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have
extra wiring.
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
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you do not shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
If you are towing a trailer that weighs more than 1,000 lbs
(450 kg), drive in AUTOMATIC OVERDRIVE (D) or,
as you need to, a lower gear. This will minimize heat
build-up and extend the life of your transaxle.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig on a hill, do the
following:
1. Apply your regular brakes, but do not shift into
PARK (P) yet.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake, and then shift to PARK (P).
5. Release the regular brakes.
4-46

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine.
Shift into a gear.
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you are
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle uid, engine oil, belts,
cooling system and brake system. Each of these is
covered in this manual, and the Index will help you nd
them quickly. If you are trailering, it is a good idea to
review these sections before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Trailer Wiring Harness
Your vehicle may have a trailer wiring harness located
at the rear of your vehicle. To use the trailer wiring
harness, you need a converter kit. Contact your dealer
for more information.

Electrical System
Add-On Electrical Equipment
Notice:Don’t add anything electrical to your
vehicle unless you check with your dealer rst.
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 airbag system. Before attempting to
add anything electrical to your vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-85.
Headlamp Wiring
The headlamp wiring is protected by internal fuses in
the fuse block. An electrical overload will cause the
lamps to go off and remain off. If this happens, have
your headlamp wiring 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, be sure to get it xed.
Power Windows and Other Power
Options
Circuit breakers in the oor console 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 xed.
5-100

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.
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 a feature of your vehicle that
you can get along without – like the radio or cigarette
lighter - and use its fuse, if it is the right amperage.
Replace it as soon as you can.
There are two fuse blocks in your vehicle: the oor
console fuse block and the underhood fuse and
relay center.
Floor Console Fuse Block
The oor console fuse block is located to the left of the
glove box near the oor. Pull the door open to access
the fuse block.
