It can be dangerous to drive with the rear
window, endgate or 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 rear window, endgate
or liftgate open or
if electrical wiring or other
cable connections must pass through the seal
between the body and the
rear window, endgate

Endgate-Mounted Spare
If your vehicle has an endgate-mounted spare tire
carrier, you must move the carrier arm out
of the way to
open the glass.
Here’s how to move the arm:
1. Squeeze the release handle to free the carrier arm.
2. Swing the carrier arm away from the endgate. You
may need to give it a slight tug.
3. To latch the carrier arm, swing it toward the endgate.

accident. If the arrows don’t
go on at all when you
signal a turn, check the fuse (see “Fuses and Circuit
Breakers” in the Index) and for burned-out bulbs.
If
you have a trailer towing option with added wiring for
the trailer lamps, a different turn signal flasher is used.
With this flasher installed, the signal indicator will flash
even
if a turn signal bulb is burned out. Check the front
and rear turn signal lamps regularly to make sure they
are working.
-7 Signal On Chime
lr your turn signal is left on ror more than 3/4 of a mile
(1.2 km), a chime will sound at each flash of the turn
signal.
To turn off the chime, move the turn signal lever
to the off position.
Headlamp High/Low Beam Changer
To change the headlamps from low beam to high or high
to low, pull the multifunction lever all the way toward
you. Then release it.
When the high beams are on, this indicator light on
the instrument panel will
also be on.

Downloaded from www.Manualslib.com manuals search engine 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
module, the wiring and the diagnostic module. For more information on the air bag system, see “Air Bag” in
the Index.
This light will come
on
when you start your engine,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
Charging System Indicator Light
If the air bag readiness light stays on after you start the
engine or comes on when
you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when
you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you if there is a problem. The
charging system light
will
come on briefly when
you turn on the ignition,
but the engine is not
running, as
a check to
show
you it is working.
It should go out once the engine is running.
If it stays
on, or comes on while
you are driving, you may have a
problem with the charging system. It could indicate that
you have problems with a generator drive belt, or
another electrical problem. Have it checked right away.
Driving while this light is
on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.

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.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra
wiring and
a heavy-duty turn signal flasher (included in
the optional trailering package).
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.
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. On
a long uphill grade, shift down and reduce your
speed
to around 45 mph (70 kmh) to reduce the
possibility of engine and transmission overheating.

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’re
pulling
a trailer. See the Maintenance Schedule for more
on this. Things that are especially important
in trailer
operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system
and brake adjustment. Each
of these is covered in this
manual, and the Index will help
you find them quickly.
If
you’re trailering, it’s 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 H-T--- ess
The light duty trailer wir is a six-wire harness
assembly. The optional heavy-duty trailer wiring
is an
eight-wire harness assembly. The harnesses are stored under the vehicle, along the passenger-side frame
crossmember on two-door vehicles or on the driver’s side
corner frame rear crossmember on four-door vehicles. The
heavy-duty trailer wiring has a 30-amp feed wire with
an
inline fuse located by the junction block. See
“Fuses and Circuit Breakers” in the Index. Both
harnesses have
no connector and should be wired by a
qualified electrical technician. The technician
can use
the following color code chart when connecting the
wiring harness to your trailer.

Dark Blue: Use for electric trailer brakes or
auxiliary wiring.
Red: Use for battery charging; it connects to the
starter solenoid (eight-wire harness only).
Light Green: Back-up lamps (eight-wire
harness only).
Brown: Taillamps and parking lamps. Yellow: Left stoplamp and turn signal.
Dark Green: Right stoplamp and turn signal.
White (Heavy Gage): Ground wire.
White (Light Gage): Auxiliary stoplamp.
Securely attach the harness to the trailer, then tape or
strap
it to your vehicle’s frame rail. Be sure you leave
it loose enough
so the wiring doesn’t bend or break,
but not
so loose that it drags on the ground. Store the
harness in its original place. Wrap the harness together
and tie it neatly
so it won’t be damaged.

Downloaded from www.Manualslib.com manuals search engine Headlamps Fuses and Circuit Breakers
The headlamp wiring is protected by an internal
circuit breaker. 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 a 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 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 or goes away. 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
you ever have a problem on the road and don’t 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.
