Understanding Radio Reception
FM stereo will give you the best sound. But FM signals will reach only
about
10 to 40 miles (16 to 65 km). And, tall buildings or hills can interfere
with
FM signals, causing the sound to come and go.
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.
AM Stereo means the Delco@ system can receive C-QUAM@stereo
broadcasts. Many AM stations around the count use C-QUAM@ to
produce stereo, though some do not. (C-QUAM
2 is a registered trademark
of Motorola, Inc.)
If your DelcoB system can get C-QUAM@, your
“STEREO” light will come on when you’re receiving it.
Be aware that hearing damage from loud noise is almost undetectable until
it is too late. Your hearing can adapt to higher volumes of sound. Sound that
seems normal can be loud and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to a safe sound level before your
hearing adapts to it.

There are some important things to remember about how to load your
vehicle.
0 The heaviest things should be on the load floor and forward of your

Be sure the load is secured properly, so driving on the off-road terrain
You’ll find other important information in this manual. See “Vehicle
Loading,’’ “Luggage Carrier” and “Tires” in the Index.
Traveling to Remote Areas
It makes sense to plan your trip, especially when going to a remote area.
Know the terrain and plan your route. You are much less likely to get bad
surprises. Get accurate maps of trails and terrain. Try to learn of any
blocked
or closed roads.
It’s also a good idea to travel with at least one other vehicle.
If something
happens to one
of them, the other can help quickly.
Does your vehicle have a winch?
If so, be sure to read the winch
instructions. In
a remote area, a winch can be handy if you get stuck. But
you’ll want to know how
to use it properly.

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. Be sure your engine
coolant mix is correct.
You may want to put winter emergency supplies in your vehicle.
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 a couple of 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.

Downloaded from www.Manualslib.com manuals search engine Driving with a Trailer
lowing 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, lights, 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 lights 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.

Use
the wrench to tighten the wheel nuts firmly in a criss-cross sequence as
shown. Remove the wheel blocks.
Storing the Jack and Spare Tire
Return the jack, wheel wrench and wheel blocks to the proper location in
your vehicle’s rear area. Secure
the items and replace the jack cover. Put the
flat tire where the spare tire was stored. If you have the underbody carrier:
1. Put the tire on the ground at the rear of the vehicle, with the valve stem
pointed down and to the rear.
2. Pull the retaining bar through the wheel.
3. Put the chisel end of the wheel wrench, on an angle, through the hole in
the rear bumper and into the hoist shaft. Turn the wheel wrench
clockwise until the tire is raised against the underside
of the vehicle.
You will hear two “clicks” when the tire is secure, but pull
on the tire to
make sure.

NOTICE:
If your vehicle has P235/75R15 or P235/70R15 size tires, don’t
use tire chains; they can damage your vehicle.
If you have other size tires, use tire chains only where legal and
only when you must. Use only
SAE Class “S” type chains that
are the proper size for your tires. Install them on the drive axle
tires (four-wheeldrive vehicles can use chains on both axles)
and tighten them as tightly
as possible with the ends securely
fastened. Drive slowly and follow the chain manufacturer’s
instructions.
If you can hear the chains contacting your vehicle,
stop and retighten them.
If the contact continues, slow down
until it stops. Driving too fast or spinning the wheels with chains
on will damage your vehicle.
Appearance Care
Remember, cleaning products can be hazardous. Some are toxic. Others can
burst into flame if you strike a match or get them on a hot part
of the
vehicle. Some are dangerous if you breathe their fumes in a closed space.
When you use anything from a container to clean your vehicle, \
be sure
to
follow the manufacturer’s warnings and instructions. And always open your\

doors
or windows when you’re cleaning the inside.
