Warning Lightsy Gages and Indicators
This section describes the warning lights and gages that may be on your
vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something is wrong be\
fore it
becomes serious enough to cause an expensive repair or replacem\
ent.
Paying attention to your warning lights and gages could also s\
ave you or
others from injury.
Warning lights
go on when there may be or is a problem with one of your
vehicle’s functions.
As you will see in the details on the next few pages,
some warning lights come on briefly when you turn the ignition\
key just to
let you know they’re working. If you are familiar with this sec\
tion, 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 toge\
ther 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 the 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.

Adjust the volume control to the lowest setting.
0 Increase volume slowly until you hear comfortably and clearly.
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). And, tall buildings or hills can interfere
with FM signals, causing the sound to come and go.
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 eac\
h other.
AM can pick up noise from things like storms and power lines. Tr\
y reducing
the treble to reduce this noise if you ever get
it.
AM Stereo
This means the Delco’ system can receive C-QUAM’ stereo broadcasts.
Many AM stations around the country use C-QUAM@ to produce ste\
reo, though some
do not. (C-QUAM@ is a registered trademark of Motorola,
kc.) If your DelcoB system can get C-QUAM@, your “STEREO’ light will
come on when you’re receiving it.
NOTICE:
Before you add any sound equipment to your ~ehicle - like a
tape player,
CB radio, mobile telephone or two-way radio - be
sure you can add
what you want. If you can, it’s very important
to do
it properly. Added sound equipment may interfere with the
operation of your vehicle’s engine, Delco@ radio or other
systems, and even damage them. And, your vehicle’s systems
may interfere with the operation of sound equipment that has
been added improperly.
So, before adding sound equipment, check with your dealer and
be sure to check Federal rules covering mobile radio and
telephone units.

Let’s review what driving experts say about what happens whe\
n the three
control systems (brakes, steering and acceleration) don’t ha\
ve enough
friction where the tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to steer and \
constantly seek
an
escape route or area of less danger.
Skidding
In a skid, a driver can lose control of the vehicle. Defensive drivers avoid
most skids by taking reasonable care suited to existing conditi\
ons, and by
not “overdriving” those conditions. But skids are always p\
ossible.
The three types of skids correspond to your Vehicle’s three control systems.
In the braking skid your wheels aren’t rolling.
In the steering or cornering
skid, too much speed or steering in a curve causes tires to slip and lose
comering force. And in the acceleration skid too much throttle causes t\
he
driving wheels to spin.
A cornering skid and an acceleration skid are best handled by easing your
foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off the accelerator pedal and
quickly steer the way you want
the vehicle to go. If you start steering
quickly enough, your vehicle may straighten out. Always be ready for a
second skid if it occurs.
Of course, traction is reduced when water, snow, ice, gravel, or other
material is
on the road. For safety, you’ll want to slow down and adjust \
your
driving to these conditions. It is important
to slow down on slippery
surfaces because stopping distance
will be longer and vehicle control more
limited.

Downloaded from www.Manualslib.com manuals search engine While driving on a surrace with reaucea traction, try yo best to a td
sudden steering, acceleration, or braking (including engme braki\
ng DY
shifting to a lower gear). Any sudden changes could cause the tires to slide.
You may not realize the surface is slippery until your vehicle is skidding.\

Learn to recognize warning clues
- such as enough water, ice or packed
snow on the road to make a “mirrored surface”
- and slow down when you
have any doubt.
Remember:
If you have the four-wheel anti-lock braking system, it helps
avoid only the braking skid. The rear-wheel anti-lock braking system helps
avoid only a rear braking skid. In a braking skid (where the\
front wheels are
no longer rolling), release enough pressure on the brakes to \
get the front
wheels rolling again. This restores steering control. Push the brake pedal
down steadily when you have to stop suddenly. As long as the front wheels
are rolling, you will have steering control.
Driving Guidelines
Off-Road Driving with Your Four-wheel
Drive Vehicle
This off-road guide is for vehicles that have four-wheel drive.
Also, see “Anti-lock Brakes’’
in the Index.
If your vehicle doesn’t have four-wheel drive, you shouldn’\
t drive off-road
unless you’re on a level, solid surface.
Off-road driving can be great fun. But it does have some definite hazards.
The greatest of these is the terrain itself.
“Off-roading” means you’ve left the great North American road system
behind. Traffic lanes aren’t marked. Curves aren’t banked. \
There are no
road signs. Surfaces can be slippery, rough, uphill or downhill\
. In short,
you’ve gone right back to nature.
Off-road driving involves some new skills. And that’s why it\
’s very
important that you read this guide. You’ll find many driving tips and
suggestions. These
will help make your off-road driving safer and more
enjoy able.
Before You Go Off-Roading
There are some things to do before you go out. For example, be sure to have
all necessary maintenance and service work done. Be sure
you read all the
information about your four-wheel drive vehicle in this manual. \
Is there
enough fuel?
Is the spare tire fully inflated? Are the fluid levels up where
they should be? What are the local laws that apply to off-roading where
you’ll be driving? If you don’t know, you should check with law
enforcement people in the area. Will you
be on someone’s private land? If
so, be sure to get the necessary permission.
