qBrake System Warning Light
This warning has the following functions:
Parking brake warning
The light illuminates when the parking
brake is applied with the ignition switched
to START or ON. It turns off when the
parking brake is fully released.
Low brake fluid level warning
If the light stays on after the parking brake
is fully released, you may have a brake
problem.
Brake system warningí
Illuminates when there is a malfunction in
the brake switch.
Drive to the side of the road and park off
the right-of-way.
You may notice that the pedal is harder to
depress or that it may go closer to the
floor. In either case, it will take longer to
stop the vehicle.
1. With the engine stopped, open the
hood and check the brake fluid level
immediately, and then add fluid if
required (page 8-22).
2. After adding fluid, check the light again.
If the warning light remains on, or if the
brakes do not operate properly, do not
drive the vehicle. Have it towed to an
Authorized Mazda Dealer. Even if the light turns off, have your
brake system inspected as soon as
possible by an Authorized Mazda Dealer.
NOTE
Having to add brake fluid is sometimes an
indicator of leakage. Consult an Authorized
Mazda Dealer as soon as possible even if the
brake light is no longer illuminated.
WARNING
Do not drive with the brake system
warning light illuminated. Contact an
Authorized Mazda Dealer to have the
brakes inspected as soon as possible:
Driving with the brake system
warning light illuminated is
dangerous. It indicates that your
brakes may not work at all or that
they could completely fail at any
time. If this light remains
illuminated, after checking that the
parking brake is fully released, have
the brakes inspected immediately.
qMalfunction Warning Lightí
When the ignition is switched ON, the
malfunction warning light illuminates and
then turns off after a few seconds.

WARNING
Do not drive the vehicle with the
malfunction warning light illuminated.Driving the vehicle with the light
illuminated is dangerous as it could
result in the loss of brake power and
cause an accident. In addition, loss of
brake power could occur when
stopping the vehicle. Have your
vehicle inspected by an Authorized
Mazda Dealer.
qABS Warning Light
The warning light stays on for a few
seconds when the ignition is switched
ON.
If the ABS warning light stays on while
you're driving, the ABS control unit has
detected a system malfunction. If this
occurs, your brakes will function normally
as if the vehicle had no ABS.
Should this happen, consult an Authorized
Mazda Dealer as soon as possible.
NOTE
lWhen the engine is jump-started to charge
the battery, uneven rpm occurs and the ABS
warning light may illuminate. If this occurs,
it is the result of the weak battery and does
not indicate an ABS malfunction.
Recharge the battery.
l(With DSC vehicles)
The brake assist system does not operate
while the ABS warning light is illuminated.
qElectronic Brake Force
Distribution System Warning
If the electronic brake force distribution
control unit determines that some
components are operating incorrectly, the
control unit may illuminate the brake
system warning light and the ABS
warning light on simultaneously. The
problem is likely to be the electronic
brake force distribution system.
WARNING
Do not drive with both the ABS warning
light and brake warning light
illuminated. Have the vehicle towed to
an Authorized Mazda Dealer to have
the brakes inspected as soon as
possible:
Driving when the brake system
warning light and ABS warning light
are illuminated simultaneously is
dangerous.
When both lights are illuminated, the
rear wheels could lock more quickly
in an emergency stop than under
normal circumstances.
