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.
The light stays on if the brake switch has
a malfunction. Consult an Authorized
Mazda Dealer.

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.

charging system warning light is
illuminated because the engine could
stop unexpectedly.

illuminates when the ignition is switched
ON or after the engine is cranked. The
warning light turns off after a specified

qTire Pressure Monitoring System
(TPMS) Warning Lightí
This warning light illuminates for a few
seconds when the ignition is switched
ON.
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.
Warning light illuminates/Warning
beep sounds
When the warning light illuminates, and
the warning beep sound is heard (about 3
seconds), tire pressure is too low in one or
more tires.

Adjust the tire pressure to the correct tire
pressure. Refer to the specification charts
(page 10-7).
CAUTION
When replacing/repairing the tires or
wheels or both, have the work done
by an Authorized Mazda Dealer, or
the tire pressure sensors may be
damaged.NOTE
lPerform tire pressure adjustment when the
tires are cold. Tire pressure will vary
according to the tire temperature, therefore
let the vehicle stand for 1 hour or only drive
it 1.6 km (1 mile) or less before adjusting
the tire pressures. When pressure is
adjusted on hot tires to the cold inflation
pressure, the TPMS warning light/beep may
turn on after the tires cool and pressure
drops below specification.
Also, an illuminated TPMS warning light,
resulting from the tire air pressure dropping
due to cold ambient temperature, may turn
off if the ambient temperature rises. In this
case, it will also be necessary to adjust the
tire air pressures. If the TPMS warning
light illuminates due to a drop in tire air
pressure, make sure to check and adjust the
tire air pressures.
lAfter adjusting the tire air pressures, it may
require some time for the TPMS warning
light to turn off. If the TPMS warning light
remains illuminated, drive the vehicle at a
speed of at least 25 km/h (16 mph) for 10
minutes, and then verify that it turns off.
lTires lose air naturally over time and the
TPMS cannot tell if the tires are getting too
soft over time or you have a flat. However,
when you find one low tire in a set of four-
that is an indication of trouble; you should
have someone drive the vehicle slowly
forward so you can inspect any low tire for
cuts and any metal objects sticking through
tread or sidewall. Put a few drops of water
in the valve stem to see if it bubbles
indicating a bad valve. Leaks need to be
addressed by more than simply refilling the
trouble tire as leaks are dangerous - take it
to an Authorized Mazda Dealer which has
all the equipment to fix tires, TPMS systems
and order the best replacement tire for your
vehicle.
