2-21 Exiting Programming Mode
To exit programming mode, do one of the following:

Press the odometer button, while in odometer mode,
for two seconds, or

turn the ignition key out of ON, or

do not program any commands for one minute while
in programming mode, or

shift out of PARK (P). See ªShifting Out of
PARK (P)º in the Index.
The programming mode message will turn off to let you
know that you are no longer in the programming mode.
Liftgate
CAUTION:
It can be dangerous to drive with the liftgate
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 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 with the setting
on bi
-level (outside air button is pressed).
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.

Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up
or down. When the turn is finished, the lever will
return automatically.
An arrow on the instrument
panel cluster and the
optional HUD display will
flash in the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by
itself when you release it.As you signal a turn or a lane change, if the arrow
flashes faster than normal, a signal bulb may be burned
out and other drivers won't see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you
signal a turn, check for burned
-out bulbs and check the
fuse (see ªFuses and Circuit Breakersº in the Index).
If you have a trailer towing option with added wiring for
the trailer lamps, the signal indicator will flash 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.

2-86
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 sensor, the air
bag modules, the wiring and the 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 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.

4-43 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 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.
If you are towing a trailer that weighs more than
1,000 lbs. (450 kg), drive in THIRD (3) instead of
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, here's
how to do it:
1. Apply your regular brakes, but don't 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.

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 is protected by an internal circuit
breaker in the floor console fuse block. 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 wiring 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 get it fixed.
Power Windows and Other Power Options
Circuit breakers in the floor 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 fixed.

6-64 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 don't have a
spare fuse, you can borrow one that has the same
amperage or use one of the spare fuses in the underhood
fuse and relay center. 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 right
amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle: the floor
console fuse block and the underhood fuse and
relay center.Floor Console Fuse Block
The floor console fuse block is located to the left of the
glove box near the floor.
The fuses marked spare are available if a replacement
fuse is needed.
Pull the door open to access the fuse block.
