Downloaded from www.Manualslib.com manuals search engine 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 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.
Headlamp High-Low Beam
f ,.
To change the
headlamps from low
beam to high or high
to low, pull the turn
signal lever all the
way toward you. Then
release it.

You can switch your headlamps from high to low beam by pulling on the
turn signal/high beam lever.
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.

Downloaded from www.Manualslib.com manuals search engine you know they’re working. If you are familiar with this section, you should
not be alarmed when this happens.
Gages can indicate when there may be or
is a problem with one of your
vehicle’s functions. Often gages and warning lights work together
to let you
know when there’s a problem with your vehicle.
When one of the warning lights comes
on and stays on when you are
driving, or when
one of the gages shows there may be a problem, check the
section that tells you what to do about
it. Please follow this manual’s advice.
Waiting
to do repairs can be costly - and even dangerous. So please get to
know your warning lights and gages. They’re
a big help.
Safety Beit Reminder Light
When the key is turned to RUN or START, a light will come on for about
eight seconds to remind people
to fasten their safety belts. Unless the
driver’s safety belt is already buckled,
a tone will also sound.
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 and module, the wiring and the
diagnostic module. For more information on the air bag system,
see “Air
Bag”
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 8-wire
harness, consisting of a 7-wire harness and one
CHMSL battery feed wire.
The harness is stored
on the passenger side of the van near the rear wheel
well. This harness has a
30 amp battery feed wire and 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.
The 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.
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 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
NOTICE:
Making very sharp turns while trailering could cause the traile\
r
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.
Turn 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.

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.

Downloaded from www.Manualslib.com manuals search engine 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.
See “Fuses and Circuit Breakers” in the Index for more
information.
Headlamps
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 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 or goes
away.
Trailer Wiring Harness
The optional eight-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 Index.
