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 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 arrows
don’t flash but just stay on, 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 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 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 also
will be on.

lighting symbol
to turn on all the lamps listed as
well as the headlamps.
Rotate the knob counterclockwise
to OFF to turn off
your lamps.
Rotate the dial next to the knob up
to adjust your
instrument panel lights. Rotate the dial up
to the first
notch for full intensity.
If you rotate the dial to the
second notch, your interior lamps will come on.
Rotate the dial next to the lamp switch down
to dim
your instrument panel lights.
Headlamps
You can switch your headlamps from high to low beam
by pulling the multifunction lever toward
you.
A circuit breaker protects your headlamps. If you have
an electrical overload, your headlamps will flicker on
and off. Have your headlamp wiring checked right away
if this happens.
Headlamps On Reminder
A reminder tone will sound when your headlamps or
parking lamps are turned on and your ignition is
in the
OFF, LOCK or ACCESSORY position. To turn the tone
off, turn the switch to
OFF.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier
for others
to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful
in the
short periods after dawn and before sunset.
The DRL system will make your headlamps come
on at
a reduced brightness when:
0 the ignition is on,
0 the headlamp switch is off and
0 the parking brake is released.

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 modules,
the wiring and the crash sensing and 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
come
on then, have it fixed so it will be
ready to warn
you if there is a problem.
Charging System Indicator Light
The charglng system light
will come on briefly when
you turn the ignition on, but
the engine is
not running, as
a check
to show you the
light is working.
Then 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 electrical charging system.
It could indicate that
you have a loose accessory 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 heatedair conditioner.

Downloaded from www.Manualslib.com manuals search engine Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra
wiring (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.
On a long uphill grade,
shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility
of engine and transmission overheating.
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a
lower temperature than at normal altitudes. If
you turn
your engine
off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar to engine overheating.
To avoid this, let the
engine run while parked (preferably on level ground)
with the automatic transmission in
PARK (P) for a few
minutes before turning
the engine off. If you do get the
overheat warning, see “Engine Overheating” in
the Index.

Downloaded from www.Manualslib.com manuals search engine Trailer Wiring Harness
If you have the optional trailering package, your vehicle
will have an eight-wire harness, including
the center
high-mounted stoplamp battery feed wire. The harness
is stored on the passenger side of
the vehicle near the
rear wheel well. This harness has a
30 amp battery feed
wire and no connector, and should be wired by
a
qualified electrical technician. After choosing an
aftermarket trailer mating connector pair, have the
technician attach one connector to the eight-wire trailer
harness and the other connector to the wiring harness
on
the trailer. Be sure the wiring harness on the trailer is
taped or strapped
to the trailer’s frame rail and leave it
loose enough so the wiring doesn’t bend or break, but
not
so loose that it drags on the ground. The eight-wire
harness must be routed out
of your vehicle between the
rear door and the floor, with enough
of the harness left
on both sides so that the trailer or the body won’t pull it.
If you do not have the optional trailering package, your
vehicle will still have a trailering harness. The harness is
located near the passenger’s side rear wheel well. It
consists of six wires that may be used by after-market
trailer hitch installers. The technician can use the
following color code chart when connecting the wiring
harness
to your trailer.
Brown: Rear lamps.
Yellow: Left stoplamp and turn signal.
0 Dark Green: Right stoplamp and turn signal.
White (Heavy Gage): Ground.
Light Green: Back-up lamps.
White (Light Gage): Center High-Mounted Stoplamp.
Blue: Auxiliary circuit (eight-wire harness only).
0 Orange: Fused auxiliary (eight-wire harness only).
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 Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the lamp switch. 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 Wiper Fuses
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 and
not snow, etc., be sure
to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel 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.
Spare fuses and a fuse puller are located in the
underhood electrical center. You can remove fuses with
the fuse puller. Remember to replace
any of the spare
fuses
you use, so you will have some if you ever need
them again.
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.
There are two fuse blocks in your vehicle: one is inside
the vehicle and one is
in the engine compartment.
