Warning Lights, Gages and lndicafors
This part describes the warning lights and gages that are 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 replacement. Paying
attention to your warning lights and gages could also save 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 part, 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
part 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.

Brake System Warning Light
BRAKE
-
K2325
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.
If the warning light goes on, there
could be
a brake problem. Have your brake system inspected right away.
This light should come on 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.
This 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 may have
a brake problem.
If the light comes on while 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.)
I CAUTION
I A Your brake system may not be working properly if the brake warning
b light is on. Driving with the brake warning light on can lead to an
I accident. If the light is still on after you’ve pulled off the road and
stopped carefully,
have the vehicle towed for service. I

Featums & Contmls
Anti-Lock Brake System Warning Light
I
PB005
With anti-lock, this light will go on when you start your eng\
ine and may stay
on for several seconds or
so. 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. Unless the regular brake system warning light is also on, you will still
have brakes,
but not anti-lock brakes. If the regular brake system warning
light is also on, see “Brake System Warning
Light” earlier in this section.

Charging System Light
1
K2328
The red charging system light is located at the upper right hand corner of
your instrument cluster. It should come on briefly when you turn on the
ignition, before starting the engine, as a check
to show you it is working.
After the engine starts, the light should go out.
If it stays on, or comes on
while you are driving, you may have a problem with your elect\
rical charging
system. It could indicate that you have a loose alternator drive belt, or that
you have some other electrical problem. Have it checked right away. Driving
while this 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.

Malfunction Indicator Lamp (Service Engine Soon Light)
RVI
llrll
I
K2329
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 comes on while you are driving,
the computer is indicating that you have a problem. You should take your
vehicle in
for service soon.
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. I

K2115
The fuel gage, when the ignition is on, tells you about how much fuel you
have left in your tank.
The gage will first indicate empty before you are out
of fuel, and you should get more fuel as soon as possible.
2-76

Listed are four situations you may experience with your fuel gage:
At the gas station, the fuel pump shuts off before the gage reads full.
It takes a little more or less fuel to fill up than the fuel gage indicated.
For example, the gage may have indicated the tank
was half full, but it
actually took a little more or less than half the tank’s capacity to
fill the
tank.
The gage moves a little when you turn a corner or speed up. \
The gage doesn’t go back to empty when you turn off the ignition.
None
of these indicate a ,problem with the fuel gage.
For information on how to
fill your fuel tank see “Fuel-Filling Your Tank” in
the Index.
For your fuel tank capacity, see “Fuel-Tank Capacity”
in the Index.
Engine Coolant Temperature Gage
260
This gage shows the engine coolant temperature. If the gage pointer moves
into the red area, about 260°F
(145°C) or more, your engine is too hot! It
means that your engine coolant has overheated.
If you have been operating
your vehicle under normal operating conditions, you should pull \
off the road,
stop your vehicle and turn
off the engine as soon as possible.
Hot Coolant Can Burn You Badly!
In “Problems on the Road”, this manual shows what to do. See “Engine
Overheating” in the Index.
