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 switch
in the START or ON position. 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.
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.
qABS Warning Light
The warning light stays on for a few
seconds when the ignition switch is turned
to the ON position.
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.

NOTElWhen 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.
qCharging System Warning Light
This warning light illuminates when the
ignition switch is turned to the ON
position and turns off when the engine is
started.
If the warning light illuminates while
driving, it indicates a malfunction of the
alternator or of the charging system.
Drive to the side of the road and park off
the right-of-way. Consult an Authorized
Mazda Dealer.
CAUTION
Do not continue driving when the
charging system warning light is
illuminated because the engine could
stop unexpectedly.

q Air Bag/Seat Belt Pretensioner
System Warning Light
If the air bag/seat belt pretensioner system
is working properly, the warning light
illuminates when the ignition switch is
turned to the ON position or after the
engine is cranked. The warning light turns
off after a specified period of time.
A system malfunction is indicated if the

these occur, consult an Authorized Mazda
Dealer as soon as possible. The system
may not work in an accident.

qTire Pressure Monitoring System
(TPMS) Warning Lightí
This warning light illuminates for a few
seconds when the ignition switch is turned
to the ON position.
Thereafter, the warning light illuminates
and a beep is heard when tire pressure is
too low in one or more tires, and flashes
when there is a system malfunction.
WARNING
If the tire pressure monitoring system
warning light illuminates or flashes, or
the tire pressure warning beep sound is
heard, decrease vehicle speed
immediately and avoid sudden
maneuvering and braking:
If the tire pressure monitoring system
warning light illuminates or flashes,
or the tire pressure warning beep
sound is heard, it is dangerous to
drive the vehicle at high speeds, or
perform sudden maneuvering or
braking. Vehicle drivability could
worsen and result in an accident.
To determine if you have a slow leak
or a flat, pull over to a safe position
where you can check the visual
condition of the tire and determine if
you have enough air to proceed to a
place where air may be added and
the system monitored again by an
Authorized Mazda Dealer or a tire
repair station.
Do not ignore the TPMS Warning Light: Ignoring the TPMS warning light is
dangerous, even if you know why it is
illuminated. Have the problem taken
care of as soon as possible before it
develops into a more serious
situation that could lead to tire
failure and a dangerous accident.
