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
or liftgate:
Make sure all windows are shut.

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 will flash in the
direction
of the turn
or lane change.
To signal a lane change. just raise or lower the lever
until the ;lrrocv starts to tlash. Hold it there until you
complete your
1mc change. The lever will return by
itself when you rclt.ast: it.
As you signal ;1 turn or LI lane change, if the arrows don’t
flash but just stay 011. ;I 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 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.
Headlamp Highkow Beam Changer

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
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.
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 corne
on then, have it fixed so it will be
ready
to warn you if there is a problem.
Charging System Indicator Light
II..
~ 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.

Downloaded from www.Manualslib.com manuals search engine Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help
you avoid situations that require heavy braking
and sudden turns.
Passing
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
I 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.
I’urn 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.

Downloaded from www.Manualslib.com manuals search engine Trailer Wiring Harness
The light duty trailer wiring 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 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.
0 Red: Use for battery charging; it connects to the
starter solenoid (eight-wire harness only).
0 Light Green: Back-up lamps (eight-wire
harness only).
Brown: Taillamps and parking lamps.
0 Yellow: Left stoplamp and turn signal.
0 Dark Green: Right stoplamp and turn signal.
0 White (Heavy Gage): Ground wire.
0 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
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.
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.
