Downloaded from www.Manualslib.com manuals search engine Normal operating range shows your engine speed during normal driving
conditions.
For example, when the needle points to 2, it means the engine is
running at 2,000 revolutions per minute (rpm). The tachometer needle will
vary all the time that the engine is running.
The red warning range tells you that your engine speed is reaching its upper
limits. Don’t drive very long with the tachometer in the red warning range.
If you have a manual transmission, shift to a higher gear as
soon as possible.
If you have an automatic transmission, lift your foot
off of the accelerator
pedal. If you drive for very long with the tachometer in the red danger
range, engine damage will result.
NOTICE:
Do not operate the engine with the tachometer in the red range,
or engine damage will occur.
The red danger range tells you that your engine speed is at its upper limits.
You should immediately shift to a higher gear, or lift your foot
off of the
accelerator pedal. If you drive for very long with the tachometer in the red
danger range, engine damage will result.
Warning Lights and Indicators
This part 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 before it
becomes serious enough to cause an expensive repair or replacement.
Paying attention
to your warning lights and gages could also save you or
others from injury.
Warning lights come 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 start the engine just to let
you know they’re working. If you are familiar with this section, you should
not be alarmed when this happens.
Gages caa 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.

The amber
Malfunction Indicator
Lamp (SERVICE
ENGINE SOON
Light) is located at the
top
of your instrument
panel.
A computer monitors operation of your fuel, ignition and emission control
systems. This light should come on when the ignition is on, but the engine is
not running,
as a check to show you it is working. If it does not come on at
all, have it fixed right away. If it
stays on, or it comes on while you are
driving, the computer is indicating that
you have a problem. You should
take your vehicle in for service soon.
NOTICE:
If you keep driving your vehicle with this light on, after awhile\

the emission controls won’t work
as well, your fuel economy
won’t be as good and your engine may not run as smoothly.
This
could lead to costly repairs not covered by your warranty.
If Your Vehicle is Equipped with 08D 11
Certain vehicles are equipped with a new emission diagnostic sy\
stem. You
can
tell whether your vehicle has this system by reading your tune-up l\
abel
located under the hood. If the label says “OBD
11” on it, the following
instructions apply.
Malfunction Indicator Lamp (SERVICE ENGINE SOON Light)
Your vehicle is equipped with an onboard computer which monitors
operation
of the emission control system. This system is called OBD I1
(On-Board Diagnostics-Second Generation) and is intended
to assure that
emissions are at acceptable levels for the life
of the vehicle, helping to
produce a cleaner environment. The “SERVICE ENGINE
SOON’ light
comes on to indicate when service is required. Malfunctions oft\

Downloaded from www.Manualslib.com manuals search engine indicated by the system before any problem is apparent, which may prevent
more serious damage to your vehicle, This system is
also designed to assist
your service technician in correctly diagnosing any malfunction.
The
“SERVICE ENGINE SOON” light should come on, as a check to show
you it is working, when the ignition is on and the engine is not running. This
light will also come during
a malfunction in one of two ways:
Light on steady - indicates a system malfunction has been detected.
Drive the vehicle to the dealer for service at your first opportunity.
Light flashing - indicates a misfire has been detected which may
damage the emission control system. The damage may be reduced by
lowering the vehicle speed, reducing the amount of cargo being hauled
or trailered, avoiding hard acceleration, or by avoiding steep uphill
grades.
If these actions are effective, the light will stop flashing and
remain
on steady. Drive the vehicle to a dealer for service. If the light
continues to flash, stop
the vehicle. Wait for a steady light to come on,
then drive the vehicle to a dealer for service.
These following conditions also may cause the “SERVICE ENGINE
SOON’ light to come on:
Low Fuel/Out of Fuel - As the vehicle starts to run out of fuel the
“SERVICE ENGINE SOON” light may come on as a result of an engine
misfire. Filling your gasoline tank should correct this condition. Make sure
to install the gas cap fully. It will require a few driving trips to turn the light
off.
Poor Quality Fuel
- Be sure to fuel your vehicle with quality fuel. Your
engine may not run efficiently
on poor fuel. Poor fuel may cause stalling,
hesitation or misfire. These conditions may
go away when the engine is
warned-up. However, poor quality fuel may cause the “SERVICE ENGINE
SOON’ light to come on.
Have a dealer check the vehicle. If no problems are found, you may want to
change to another brand of fuel.
Driving Through Standing Water
- Driving your vehicle through puddles
of deep standing water may result in a temporary misfire condition. This
condition will usually correct itself shortly after the electric\
al system dries
out. It will require a few driving trips to turn the light off.

you are driving, you may have a problem with the charging system. It could
indicate that you have problems with a generator drive belt, or another
electrical problem. Have it checked right away. Driving while t\
his light is on
could drain your battery.
If you must drive a short distance with the light on, be certain to turn off all
your accessories, such as the radio and air conditioner.

Trailer Wiring Harness
Your vehicle will have a 5-wire and may have a 7-wire harness.
The light duty trailer wiring is a 5-wire harness assembly taped and bundled
at the left corner
of the vehicle. The harness has no connector, and you
should have
a qualified service person wire your harness for you.
The heavy duty trailer wiring is
a 7-wire harness assembly. It is stored
under the vehicle, along the passenger-side frame crossmember on
two-door vehicles and on the driver-side corner frame crossmember on
four-door vehicles. It has a 30-amp feed wire with an inline fuse located by
the junction block. See “Fuses and Circuit Breakers” in
the Index.
Both the 5-wire harness and the 7-wire harness have 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.
Store the harness
in its original place. Wrap the harness together and tie it
neatly
so it won’t be damaged.

1. Adjust the volume control to the lowest setting.
2. Increase volume slowly until you hear comfortably and clearly.
NOTICE:
Before you add any sound equipment to your vehicle - 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.
Care of Your Cassette PIayer and Tape
A tape player that is not cleaned regularly is subject to reduce\
d sound
quality, ruining the cassette, or damaging the mechanism. Tape cassettes that
are not properly stored in their plastic cases away from contaminan\
ts, direct
sunlight, and extreme heat, may not operate properly and could cause
premature failure
of the tape player.
Your tape player should be cleaned with every
50 hours of use to provide
optimum performance. Your radio may display “Cln” (Clean) to indicate
that you have used your tape player for
50 hours without re-setting the tape
clean timer.
If you notice a reduction in sound quality, regardless of when
the tape player was last cleaned,
try playing a different cassette to see if the
tape or tape player is at fault. If the second cassette results in no
improvement in sound quality,
try cleaning the tape player.
Proper tape player cleaning should be done with a scrubbing action,
non-abrasive cleaning cassette. This is a wet-type cleaning system that uses
a cleaning cassette with pads which scrub the tape head as the \
hubs of the
cleaner cassette turn.
To properly clean your tape player, follow instructions
with the cleaning cassette. If you use this type of cleaner, the radio may
display an error and eject the cartridge. This is normal and \
is the result
of an
added feature
in the tape player that detects broken tapes. If an error occurs,
you will need to insert the cleaning cassette at least
3 times to thoroughly
clean the tape player.
3-18

Downloaded from www.Manualslib.com manuals search engine You may prefer to use a non-scrubbing action, wet-type cleaner. This type
of cleaner uses a fabric belt to clean the tape head. This type of cleaner
cassette will not cause an error, but it may not clean the tape player as
thoroughly as the scrubbing type cleaner.
A scrubbing action cleaner cassette is available through your retailer (SPO
12344600).
Cassettes are subject to wear and the sound quality may degrade over time.
Always verify that the cassette tape
is in good condition and the tape player
is clean before obtaining service on your tape player.
t
NOTICE:
Cassette tape adapter kits for portable CD players will not work
in your cassette player. These adapters will cause the radio t\
o
display an error and the adapter cassette will be ejected.
Care of Compact Discs
Handle discs carefully. Store them in their original cases or other protective
cases and away from direct sunlight and dust. If the surface of a disc
is
soiled, dampen a clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch
the signal surface
when handling discs.
Pick up discs by
grasping the outer
edges or the edge
of
the hole and the outer
edge.
Antenna Care
The fixed mast antenna can withstand most car washes without being
damaged.
If the mast should ever become slightly bent, you can straighten it
out by hand. If the mast is badly bent, as it might be by vandals, you should
replace it.
Check every once in a while to be sure the mast
is still tightened to the
fender.

e
e
e
e
a
a
a
0

“Drive ahead.” Look down the road, to the sides, and to crossroads for
situations that might affect your passing patterns.
If you have any doubt
whatsoever about making a successful pass, wait for
a better time.
Watch for traffic signs, pavement markings, and lines. If you can see a
sign up ahead that might indicate a
turn or an intersection, delay your
pass.
A broken center line usually indicates it’s all right to pass \
(providing the road ahead is clear). Never cross a solid line
on your
side of the lane or a double solid line, even if the road seems empty of
approaching traffic.
Do not get too close to
the vehicle you want to pass while you’re
awaiting
an opportunity. For one thing, following too closely reduces
your area of vision, especially if you’re following a larger vehicle.
Also, you won’t have adequate space if the vehicle ahead suddenly
slows or stops. Keep back a reasonable distance.
When it looks like a chance to pass is coming up,
start to accelerate but
stay in the right lane and don’t get too close. Time your \
move
so you,
will be increasing speed as the time comes to move into the \
other lane.
If the way
is clear to pass, you will have a “running start” that more\

than makes up for the distance you would lose by dropping back. And
if something happens to cause you to cancel your pass, you need only
slow down and drop back again and wait for another opportunity.
If other cars are lined up to pass a slow vehicle, wait your tu\
rn. But
take care that someone isn’t trying to pass you as you pull out to pass
the slow vehicle. Remember to glance over your shoulder and check
the blind spot.
Check your mirrors, glance over your shoulder, and start your left lane
change signal before moving out
of the right lane to pass. When you
are far enough ahead
of the passed vehicle to see its front in your inside
mirror, activate your right lane change signal and move back i\
nto the
right lane. (Remember that your right outside mirror is convex. The
vehicle you just passed may seem
to be farther away from you than it
really is.)
Try not to pass more than one vehicle at a time on two-lane roads.
Reconsider before passing the next vehicle.
Don’t overtake a slowly moving vehicle too rapidly. Even tho\
ugh the
brake lamps are not flashing, it may be slowing down or start\
ing to
turn.
If you’re being passed, make it easy for the following driver to get
ahead of you. Perhaps you can ease a little to the right.
