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

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.

Malfunction Indicator Lamp (Service Engine Soon Light)

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
