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.
I 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 can 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.

When the key is turned to RUN or START, a tone will come on for about
eight seconds
to remind people to fasten their safety belts, unless the
driver’s safety belt
is already buckled. The safety belt light will also come
on and stay on for about 20 seconds, then it will flash for about 55 seconds.
If the driver’s belt is already buckled, neither the tone nor the light will
come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument panel, which shows
AIR
BAG. The system checks the air bag’s electrical system for
malfunctions. The light tells you if there is an electrical problem.
The
system check includes the air bag sensors and module, the wiring and the
diagnostic module. For more information on the air bag system, see “Air
Bag” in the Index.

Downloaded from www.Manualslib.com manuals search engine You will see this light flash for a few seconds when you turn your ignition
to RUN or START. Then the light should go out. This means the system is
ready.
If the air bag readiness light doesn’t come
on when you start your vehicle,
or stays on, or comes
on when you are driving, your air bag system may not
work properly. Have your vehicle serviced right away.
Brake System Warning Light
-1
BRAKE
Your vehicle’s hydraulic brake system is divided into two parts. If one part
isn’t working, the other part can still work and stop you. For good braking,
though, you need both parts working well.
Your vehicle also has rear-wheel or four-wheel anti-lock brakes. See
“Anti-Lock Brakes” in the Index. If the warning light comes on, there could
be a brake problem with either your regular or rear-wheel anti-lock brakes,
or both. Have your brake system inspected right away.
This light should come
on briefly as you start the vehicle. If it doesn’t come
on then, have it fixed
so it will be ready to warn you if there’s a problem.
If the light comes on while you are driving, pull off the road and stop
carefully. You may notice that the pedal is harder
to push. Or, the pedal may
go closer to the floor. It may take longer to stop. If the light
is still on, have
the vehicle towed for service. (See “Towing Your Vehicle” in the Index.)
2-58

Downloaded from www.Manualslib.com manuals search engine The brake system warning light will also come on when you set your
parking brake, and it will stay on if your parking brake doesn’t release fully.
If it stays on after your parking brake is fully released, it means you have a
brake problem.
Anti-Lock Brake System Warning Light (Option)
If your vehicle has four-wheel anti-lock brakes, it will have this yellow
light.
With the anti-lock brake system, this light will come on when you
start your
engine and may stay on for several seconds. That’s normal. If the light
doesn’t come
on, have it fixed so it will be ready to warn you if there is a
problem.
If the light stays on, or comes on when you’re driving, your vehicle needs
service. If the regular brake system warning light isn’t on, you still have
brakes, but you don’t have anti-lock brakes. If the regular brake system
warning light is also
on, you don’t have anti-lock brakes and there’s a
problem with your regular brakes. See “Brake System Warning Light”
earlier in this part.

Indicator lights go on when you use your turn signals, change from low
beam headlights
to high beams, or when you use your hazard flashers. The
next few pages will also tell you about the indicator lights on your vehicle
and help
you locate them.
Malfunction Indicator Lamp (SERVICE ENGINE SOON
Light)
The amber
Malfunction Indicator
Lamp (SERVICE
ENGINE SOON
Light) is located at the
top of your instrument
panel.
SERVICE
ENGINE
SOON
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 OBD I1
Certain vehicles with 4.3 liter engines are equipped with a new emission
diagnostic system. You can tell whether your vehicle has this system
by
reading your tune-up label located under the hood. If the label says “OBD
11” on it, the following instructions apply.

Downloaded from www.Manualslib.com manuals search engine 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 often will be
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:
0
0
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 FueVOut 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 electrical system dries
out. It will require a few driving trips to turn the light off.
