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 ªTowing Your Vehicleº in
the Index.
CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you've
pulled off the road and stopped carefully, have
the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light 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
With the anti-lock brake
system, the light will
come on when your engine
is started and may stay
on for three seconds.
That's normal.
If the anti
-lock brake system warning light stays on
longer than normal after you've started your engine, turn
the ignition off. Or, if the light comes on and stays on
when you're driving, stop as soon as possible and turn
the ignition off. Then start the engine again to reset the
system. If the light still stays on, or comes on again
while you're driving, your vehicle needs service. If the
light is on and the regular brake system warning light
isn't on, you still have brakes, but you don't have
anti
-lock brakes. Adjust your driving accordingly.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.

If the traction control system is affected by an
engine
-related problem, the system will turn off and
the warning light will come on.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
Low Traction Light
If you have the
Enhanced Traction
System or the Traction
Control System, this
light will also come on
when the system is
limiting wheel spin.
You may feel or hear the system working, but this is
normal. Slippery road conditions may exist if the low
traction light comes on, so adjust your driving
accordingly. The light will stay on for a few seconds
after the Enhanced Traction System or the Traction
Control System stops limiting wheel spin. See
ªEnhanced Traction Systemº or ªTraction Control
Systemº in the Index.The low traction light also comes on briefly when you
turn the ignition key to RUN. If the light doesn't come
on then, have it fixed so it will be there to tell you when
the Traction Control System or Enhanced Traction
System is active.
Engine Coolant Temperature Light
This light tells you that
the engine coolant has
overheated or the radiator
cooling fan is not working.
If you have been operating the vehicle under normal
driving conditions, you should pull off the road, stop the
vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.
Page 149 of 373
2-80 Engine Coolant Temperature Gage
United States Canada
You have a gage that shows the engine coolant
temperature. If the gage pointer moves into the shaded
area, the engine is too hot.
That reading means the same thing as the warning light.
It means that the engine coolant has overheated. If you
have been operating the vehicle under normal
conditions, you should pull off the road, stop the
vehicle, and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
If this light comes on,
the system is low on
coolant and the engine
may overheat.
See ªEngine Coolantº in the Index and have the vehicle
serviced as soon as possible.

2-84 Oil Warning Light
United States Canada
If you have a problem with your oil pressure, this light
may stay on after you start your engine, or come on
when you are driving.
This indicates that oil is not going through your engine
quickly enough to keep it lubricated. The engine could
be low on oil or could have some other oil problem.
Have it fixed right away.
The oil light could also come on in two other situations:
When the ignition is on but the engine is not running,
the light will come on as a test to show you it's
working. The light will go out when you turn the
ignition to RUN. If it doesn't come on with the
ignition on, you may have a problem with the fuse or
bulb. Have it fixed right away.If you make a hard stop, the light may come on for a
moment. This is normal.
CAUTION:
Don't keep driving if the oil pressure is low.
If you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

2-86 Fuel Gage
United States Canada
The fuel gage tells you about how much fuel you have
left when the ignition is on. When the indicator nears
empty, you still have a little fuel left, but you should
get more soon.
Here are four things owners usually ask about the fuel
gage. All these situations are normal and do not indicate
a problem with the fuel gage:
At the gas station, the pump shuts off before the
gage reads full.It takes more (or less) fuel to fill up than the gage
indicates. For example, the gage reads half full,
but it took more (or less) than half the tank's
capacity to fill it.
The gage pointer may move while cornering, braking
or speeding up.
The gage may not indicate full when the ignition is
turned off.
Low Fuel Light
If your fuel is low, the
warning light near the
fuel gage will go on.
It will also come on for a few seconds when you first
turn on the ignition as a check to show you it's working
properly. If it doesn't come on then, see your dealer
for service.
