Downloaded from www.Manualslib.com manuals search engine Standard Cluster Digital Cluster
A green 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 green 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 your vehicle has the digital instrument cluster, the turn signal arrows will
flash at
a faster rate if a signal bulb is burned out.
If a bulb is burned out, replace it to help avoid an accident. If the green
arrows don’t go on at all when you signal a turn, check the fuse (see “Fuses”
in the Index) and for burned-out bulbs.
If
you have a trailer towing option with added wiring for the trailer lights, 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 lights regularly to make sure they are working.

indicator lights.
You can switch your headlights from high to low beam by pulling on the
multifunction lever.
A circuit breaker protects your headlights. If you have an electrical
overload, your headlights will flicker
on and off. Have your headlight
wiring checked right away
if this happens.
Fog Lamps (Option)
The fog lamp switch is on the instrument panel under the headlight switch.
Press the right side of
the switch
to turn the
fog lamps
on, and the
left side of the switch
to turn them off. A
light will glow in the
right side
of the
switch
when they are
on.
Remember, fog lamps alone
will not give off as much light as your
headlights.
Never
use your fog lamps in the dark without turning on your headlights.
Fog lamps will
go off whenever your high beam headlights come on. When
the high beams
go off, the fog lamps will come on again.

Downloaded from www.Manualslib.com manuals search engine Trailer Wiring Harness
Your vehicle may have either a 5-wire or 7-wire harness.
The light duty trailer wiring is a 5-wire harness assembly taped and bundled
at the left corner
of the vehicle interior, next to the endgate. The harness has
no connector, and you should have a qualified service person wire your
harness for
you. It must be routed out of your vehicle and attached so that
the trailer or the body won’t pull
it.
The heavy duty trailer wiring is a 7-wire harness assembly consisting of a
5-wire harness and a 2-wire harness taped together and stored under the
vehicle, along
the rear frame crossmember. It has a 30-amp feed wire with
an inline fuse located by the junction block. See “Fuses and Circuit
Breakers” in the Index.
Both the 5-wire harness and the 2-wire harness have no connector and
should be wired by a qualified service person. 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 Making Turns
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 a different turn signal
flasher and extra wiring. The green arrows
on your instrument panel will
flash whenever you signal a turn or lane change. Properly hooked up, the
trailer lights 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 kdh) to reduce the possibility of engine and transmission overheating.
If you have an automatic transmission,
you should use “D” when towing a
trailer. Operating your vehicle in “D” when towing a trailer will minimize
heat buildup and extend the
life of your transmission. Or, if you have a
manual transmission with
fifth gear, it’s better not to use fifth gear, just
drive in fourth gear (or, as
you need to, a lower gear).
Parking on Hills
You really should not park your vehicle, with a trailer attached, on a hill. If
something goes wrong, your rig could start to move. People can be injured,
and both your vehicle and the trailer can be damaged.
But if you ever have
to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into “P” (Park) yet, or into
gear for a manual transmission.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
chocks absorb
the load.

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 Light Wiring
See “Trailer Wiring Harness” in the Index.
Power Winches
If you wish to use a power winch on your vehicle, only use it when your
vehicle
is stationary or anchored.
! NOTICE:
~ When operating a power winch on your vehicle always leave the \
l transmission in the neutral position. Do not leave an automatic
transmission in
P (Park) or a manual transmission in gear or the
transmission may be damaged.
Use the regular brakes, set the parking brake or block the wheels to keep
your vehicle from rolling.

Add-on Lxtrical 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.
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 in the
wiring itself. This greatly reduces the chance of fires caused by electrical
problems.
6-60

Downloaded from www.Manualslib.com manuals search engine Headlights
The headlight wiring is protected by a circuit breaker in the light switch. An
electrical overload will cause the lights to go on and off. If this happens,
have your headlight 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 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.
Trailer Wiring Harness
The optional seven-wire trailer wiring harness is protected by an in-line
fuse in the battery feed wire. This fuse is near the junction block. See
“Trailer Wiring Harness” in the
Features & Controls section.
Fuse Block
The fuse block is in
the instrument panel
on the driver’s side.
Remove the cover
with a screwdriver and
then you
can remove
fuses with a fuse
extractor.
