Brake System Warning Light
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 comes on, there could be
a brake
problem. Have your brake system inspected right away.

This light should come on
briefly when you turn the
ignition key to RUN. If it

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.)
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.

If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
Avoiding steep uphill grades.
If you are towing a trailer. reduce the anlount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains
on steady. see “If
the Light Is On Steady” following.
If the light continues t.o flash, when it is safe to do so.
stop the \?el?ic&~. Find a safe place to park your vehiclc.
Turn the key off,
wait at least 10 seconds and restart the
engine.
If the light remains on steady, see “If the Light
Is On Steady” following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did
you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making s111-e to fully install
the cap. The diagnostic system can cleter~nine
if the fuel cap
has been left off
or improperly installed. A loose or
missing fuel cap
will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed should turn
the light off,
Did you *just drive through a deep puddle of water’!
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Have you recently changed brands of fuel?
I1 so, be sure to fuel your vehicle with cpality fuel (see
“Fuel”
in the Index). Poor fuel quality will cause your
engine not to
r11n as e,fficiently as designed. You may
notice this
as stalling after start-up, stalling when you put
the vehicle
into gear, mistlring, hesitation on acceleration
or
stumbling on acceleration. (These conditions may go
away once the engine is warmed up.) This will be detected
by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use.
It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light. turn off.
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic
tools to fix any mechanical or electrical
problcnls that may have developed.
