Remote Cassette Player - ETRR AM-FM Stereo Audio
Compact Disc ATC System
System that includes a
remote cassette player,
the cassette player
is
located in the center
of the instrument
panel.

Understanding Radio Reception
FM stereo will give you the best sound. But FM signals will reach only
about
10 to 40 miles (I 6 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 stornx 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 county use C-QUAM“ to
produce stereo, though some
do not. (C-QUAM& is a registered trademark
of Motorola, Inc.)
If your Delco@ system can get C-QUAMa, your
“STEREO” light will come on when you’re receiving it.

Hard packed snow and ice offer the worst tire traction. On these surfaces,
it’s very easy
to lose control. On wet ice, for example, the traction is so poor
that you will have difficulty accelerating. And if you do get moving, poor
steering and difficult braking can cause you to slide
out of control.
A CAUTION:
Driving on frozen lakes, ponds or rivers can be dangerous.
Underwater springs, currents under the ice, or sudden thaws
can weaken the ice. Your vehicle could fall through the ice and
you and your passengers could drown. Drive your vehicle on
safe surfaces only.
Driving In Water
Light rain causes no special off-road driving problems. But heavy rain can
mean flash flooding, and flood waters demand extreme caution.
Find out how deep the water is before
you drive through it. If it’s deep
enough to cover your wheel hubs, axles, or exhaust pipe, don’t try
it - you
probably won’t get through. Also, water that deep can darnage your axle and
other vehicle parts.
If the water isn’t too deep, then drive through
it slowly. At fast speeds, water
splashes
on your ignition system and your vehicle can stall. Stalling can also
occur if you get your tailpipe under water. And, as long as your tailpipe is
under water, you’ll never be able to start your engine. When
you go through
water, remember that when your brakes get wet,
it may take you longer to
stop.
A CAUTION:
Driving through rushing water can be dangerous. Deep water
can sweep your vehicle downstream and you and your
passengers could drown.
If it’s only inches deep, it can still wash
away the ground
from under your tires, and you could lose
l traction and roll the vehicle over. Don’t drive through rushing
water.
If you have a diesel engme, see “Driving Through Water (Diesel Engines)”
in the Index for more information on driving through water.

1 A CAUTION:
If you don’t shift down, your brakes could get so hot that they
wouldn’t work well. You would then have poor braking or even
none going down a hill.
You could crash. Shift down to let your
engine assist your brakes on a steep downhill slope.
A CAUTION:
Coasting downhill in NEUTRAL (N) or with the ignition off is
dangerous. Your brakes will have to
do all the work of slowing
down. They could get
so hot that they wouldn’t work well. You
could crash. Always have your engine running and your vehicle
in gear when you
go downhill.
Know how to go uphill. You may want to shift down to a lower gear.
The lower gears help cool your engine and transmission, and you can
climb
the hill better.
Stay in your own lane when driving on two-lane roads in hills or .
mountains. Don’t swing wide or cut across the center of the road. Drive
at speeds
that let you stay in your own lane.
As you go over the top of a hill, be alert. There could be something in
your lane, like a stalled car or an accident.
You may see highway signs on mountains that warn of special
problems. Examples are long grades, passing or no-passing
zones, a
falling rocks area, or winding roads. Be alert
to these and take
appropriate action.

You could be injured if the vehicles roll. Set the parking brake firmly
on each vehicle. Put an automatic transmission in PARK (P) or a
manual transmission in NEUTRAL (N). If you have a
four-wheel-drive vehicle, be sure the transfer case is not in NEUTRAL
(N).
3. Turn off the ignition on both vehicles. Turn off all lights that aren’t
needed, and radios. This
will avoid sparks and help save both batteries.
And it could save your radio!
NOTICE:
If you leave your radio on, it could be badly damaged. The
repairs wouldn’t be covered by your warranty.
4. Open the hoods and locate the batteries. Find the positive (+) and
negative
(-) terminals on each battery.
A CAUTION:
Using a match near a battery can cause battery gas to explode.
People have been hurt doing this, and some have been blinded.
Use
a flashlight if you need more light.
Be sure the batteries have enough
water. You don’t need to add
water to the Delco Freedom@ battery (or batteries) installed in
every new
GM vehicle. But if a battery has filler caps, be sure
the right amount of fluid is there.
If it is low, add water to take
care
of that first. If you don’t, explosive gas could be present.
Battery fluid contains acid that can burn you. Don’t get
it on
you.
ff you accidentally get it in your eyes or on your skin, flush
the place with water and get medical help immediately.
5. Check that the jumper cables don’t have loose or missing insulation. If
they do,
you could get a shock. The vehicles could be damaged, too.
Before you connect the cables, here are some basic things you should
know. Positive
(+) will go to positive (+) and negative (-) will go to
negative
(-) or a metal engine part. Don’t connect (+) to (-) or you’ll
get
a short that would damage the battery and maybe other parts, too.

To wing Your Vehicle
Try to have your GM dealer or a professional towing service tow your
vehicle. They can provide the right equipment and know how to tow
it
without damage.
If your vehicle has been changed since
it was factory-new. by adding such
things like fog lamps, aero skirting,
or special tires and wheels, these things
could be damaged during towing.
Before you do anything,
turn on the hazard warning flashers.
When you call, tell the towing service:
0 That your vehicle has rear-wheel drive, or that it has the four-wheel
drive option.
The make, model, and year of your vehicle.
0 Whether you can move the shift lever for the transmission and transfer
case,
if you have one.
If there was an accident. what was damaged.
A CAUTION:
To help avoid injury to you or others:
Never let passengers ride in a vehicle that is being towed.
0 Never tow faster than safe or posted speeds.
0 Never tow with damaged parts not fuIly secured.
0 Never get under your vehicle after it has been lifted by the
tow truck.
0 Always use separate safety chains on each side when towing a
vehicle.
0 For pickups (except cab chassis models), use T-hooks on front
. of vehicle, J-hooks on rear.
For cab chassis models, use J-hooks on front and rear of
vehicle.
When your vehicle is being towed, have the ignition key off. The steering
wheel should be clamped
in a straight-ahead position, with a clamping
device designed for towing, service.
Do not use the vehicle’s steering
column lock for this. The transmission and transfer case, if
you have one,
should be
in NEUTRAL (N) and the parking brake released.

NOTICE:
If there is water in your diesel fuel and the weather is warm or
humid, fungus and bacteria can grow in the fuel. They can
damage your fuel system. You'll need a diesel fuel biocide to
sterilize your fuel system. Your dealer can advise
you if you ever
need this.
If your fuel tank needs to be purged to remove water, see your
dealer or a qualified technician. Improper purging can damage
your fuel system.
Running Out of Fuel (Diesel Engines)
If the engine stalls and you think that you've run out of fuel, do this:
First, open the fuel filter air bleed valve.
Briefly crank the
engine and have
someone watch the
bleed valve. If there is
air, then you are
probably
out of fuel.
To restart your engine:
I. If you're parked on a level surface, add at least two gallons of fuel.
However, if you're parked
on a slope, you may need to add up to five
gallons of fuel.
2. With the air bleed valve open, turn your ignition key to START for 10
to
15 seconds to crank (but not start) your engine. Wait one minute
between intervals
of cranking to allow the starter motor to cool.
Overheating the starter motor could damage it. Keep doing this until
you can just see some clear fuel at the air bleed valve. (If, during this
step, the engine starts, turn the ignition off and close the valve before
restart.)

cloth.
3. Close the air bleed valve.
4. Turn the ignition key to START for 10 to 15 seconds at a time until
your engine starts.
Fuel Filter Replacement (Diesel Engines)
If you want to change the fuel filter yourself, here's how to do it:
A CAUTION:
Diesel fuel is flammable. It could start a fire if something ignites
it, and you could be burned. Don't let it get on hot engine parts,
and keep matches or other ignition sources away.
First. drain any water from the filter following the procedure for draining
water listed previously.
Your vehicle's engine should be off until the end
