Understanding Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations
to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble
to reduce this noise if you ever get it.
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach only about
10 to 40 miles ( 16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound
to come and go.

Downloaded from www.Manualslib.com manuals search engine Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter. Include
an ice scraper, a small brush or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing,
a small shovel, a flashlight, a red cloth and
reflective warning triangles. And,
if you will be driving
under severe conditions, include a small bag
of sand, a
piece of old carpet or a couple of burlap bags
to help
provide traction. Be sure you properly secure these
items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet the
road probably have good traction.
However, if there
is snow or ice between your tires and
the road,
you can have a very slippery situation. You’ll
have a
lot less traction or “grip” and will need to be
very careful.
0 You may want to put winter emergency supplies in
your vehicle.

Towing a Trailer
,- CAUTION:
If you don’t use the correct equipment and drive
properly, you can lose control when you pull
a
trailer. For example, if the trailer is too heavy,
the brakes may not work well
-- or even at all.
You and your passengers could be seriously
injured. Pull
a trailer only if you have followed
all the steps in this section. Ask your dealer for
advice and information about towing
a trailer
with your vehicle.
4-28

Downloaded from www.Manualslib.com manuals search engine Towing a trailer requires a certain amount of experience.
Before setting
out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight
of the
trailer. And always keep in mind that the vehicle
you are
driving is now a good deal longer and
not nearly as
responsive as your vehicle is by itself.
Before
you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment.
If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets
you check your
electrical connection
at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help you avoid situations that require heavy braking
and sudden turns.
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.

Downloaded from www.Manualslib.com manuals search engine Trailer Wiring Harness
The light-duty trailer wiring harness is a six-wire
harness assembly. The optional heavy-duty trailer
wiring package is an eight-wire harness assembly. The
harness is stored under the vehicle, along the driver’s
side rear corner of the frame rail. The heavy-duty trailer
wiring harness has a 30-amp feed wire. Both harnesses
come without connectors and should be wired by a
qualified electrical technician. The technician can use
the following color code chart when connecting the
wiring harness to your trailer.
Dark Blue: Use for electric trailer brakes (eight-wire
harness only)
Orange: Trailer accessory (eight-wire harness only)
0 Light Green: Back-up lamps
0 Brown: Parking lamps
Yellow: Left stoplamp and turn signal
0 Dark Green: Right stoplamp and turn signal
0 White (heavy gage): Ground wire
White (light gage): Center high-mounted stoplamp
Securely 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.

::.. ..,. .. .
. . . . , . . .. . .j
Your spare tire is stored underneath the rear of your
vehicle. You will use the ratchet and extension to lower
the spare tire.
A flat rear tire reduces clearance to remove the spare
tire. If there is less than 12 inches (30.48 cm) between
the ground and the rear bumper or any trailer hitch, jack
up the vehicle until the flat tire is
off the ground. (See
“Removing the Flat Tire” and “Installing the Spare
Tire,” Steps
4 through 8, in this section.) Unless your vehicle has
a flat rear tire, do not remove
or restore a tire frodto a storage position under the
vehicle while the vehicle is supported by a jack. Always
tighten the tire fully against the underside
of the vehicle
when restoring.
If you have a vehicle which was completed from a cab
and chassis, refer to the information from the body
supplierhnstaller.
The spare
tire is a full size tire, like the other tires on
your vehicle.
For cargo vans, and all
passenger vans except those
with the 15-passenger
seating arrangement, the
jack is secured in the rear
passenger side corner
of
the vehicle.
Remove the retaining wing
bolt and lift it off the
mounting bracket. Set the jack and jacking equipment
near the flat tire.
