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.
A
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.

Safety Belt Reminder Light
When the key is turned to RUN or START, a tone will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about
20 seconds,
then it will flash for about
55 seconds. If the driver’s
belt is already buckled, neither the tone nor the
light will come on.
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.

You will see this light flash

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.

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.
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.
Tbrn 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.
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.

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.
0 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.
0 WHITE (Light Gage): Center High-Mounted
0 BLUE: Auxiliary circuit (eight-wire harness only).
0 ORANGE: Fused auxiliary (eight-wire harness only).
xore the harness in its original place. Wrap the harness
together and
tie it neatly so it won’t be damaged.

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