It can be dangerous to drive with the rear
window or endgate 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.

endgate open or if electrical wiring or other cable
connections must pass through the seal between
the body and the rear window or endgate:

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

to make sure they

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 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 module,
the wiring and the diagnostic module. For more
information
on the air bag system, see “Air Bag” in
the Index.
AIR
BAG
You will see this light flash
for a few seconds when you
turn your ignition to RUN
or START. Then the light
should go
out. This means
the system is ready.
If the air bag readiness light doesn’t come on when you
start your vehicle, or stays on,
or comes on when you
are driving, your air bag system may not work properly.
Have your vehicle serviced right away.
Charging System Indicator Light
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.

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 has to have extra
wiring and a heavy-duty turn signal flasher (included
in
the optional trailering package).
The green 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 green 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.

Downloaded from www.Manualslib.com manuals search engine 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 Harness
The light duty trailer wiring is a six-wire harness
assembly. The 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
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.

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 “Servicing
Your Air Bag-Equipped Vehicle”
in the Index.
Headlamps
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.

Downloaded from www.Manualslib.com manuals search engine 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 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.
Instrument Panel Fuse Block
The fuse block is at the
driver’s end
of the
instrument panel.
Remove the cover by turning the fastener
counterclockwise. Extra fuses and the fuse extractor are
provided
in the cover. To reinstall the fuse panel cover,
push
in and turn the fastener clockwise.
