Downloaded from www.Manualslib.com manuals search engine To signal a lane change, just raise or lower the lever until the green ar\
row
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 chi' -- 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 signa\
l 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 tr\
ailer lights, a
different turn signal flasher is used. With this flasher instal\
led, 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.
Operation of Lights
Although your vehicle’s lighting system (headlights, parking \
lights, fog lamps,
side marker lights and tail lights) meet all applicable Federa\
l lighting
requirements, certain states and providences may apply their own\
lighting
regulations that may require special attention before you operat\
e these lights. For example, some jurisdictions may require that you operate yo\
ur lower
beam lights with fog lamps at all times, or that headlights b\
e turned on
whenever you must use your windshield wipers. In addition, most\
jurisdictions
prohibit driving solely with parking lights, especially at dawn \
or dusk.
It is
recommended that you check with your own state or provincial h\
ighway
authority for applicable lighting regulations.

Turn the dial above the headlight switch to the right to make your instrument
panel and transfer case lights brighter. Turning the dial all the way to the
right until it clicks will turn on the interior lights.
Turn the dial to the left to dim your instrument panel and transfer case
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
KO940
Use your optional fog lamps for better vision in foggy or misty conditions.
Your parking lights and/or low beam headlights must be on or your lamps
won’t work.
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.

Standard Cluster Digital Cluster
I
KO278
When your engine
is not running, but the ignition is on (in the Run position),
the gage shows your battery's state of charge in
DC volts. When the engine
is running, the gage shows the condition of the charging system. Readings
between the low and high warning zones indicate the normal operating range.
On the digital cluster, a box around the voltmeter symbol will\
begin to flash
when the charging system needs service.
You can only drive for a short time with the reading in either warning zone. If
you must drive, turn
off all unnecessary accessories.
Readings in either warning zone indicate a possible problem in the electrical
system. Have the vehicle serviced as soon as possible.
mailer Wiring Harness
Your vehicle may have either a 5-wire or 7-wire harness.
The 5-wire harness is stored along the left rear frame crossme\
mber. The harness has no connector, and you should have a qualified serv\
ice 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.

KO250
The 7-wire harness is stored under your vehicle along the rear frame
crossmember. This harness has a
30 Amp. in-line fused battery feed wire and
no connector, and should be wired by a qualified service perso\
n. 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 Your Driving and the Road
Following Distance
Stay at least twice as far behind the vehicle ahead as you w\
ould when
driving your vehicle without a trailer. This can help you avoi\
d situations that require heavy braking and sudden turns.
Passing
You’ll need more passing distance up ahead when you’re to\
wing 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 left, just move your 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
When you’re turning with a trailer, make wider turns than n\
ormal. Do this so
your trailer wheels 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 pan\
el 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 work\
ing.
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 ove\
rheating.
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).

2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
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 esp\
ecially important in trailer operation are automatic transmission fluid (don’t ove\
rfill),
engine oil, axle lubricant, belt, cooling system, and brake adj\
ustment. 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
Use the regular brakes, set the parking brake Or UIWK ihe wheels IW keep
your vehicle from rolling.

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.
