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 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:

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 is switched ON 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.
qEngine Oil Pressure Warning Light
This warning light illuminates when the
ignition is switched ON and turns off
when the engine is started.
This warning light indicates low engine
oil pressure.
If the light illuminates while driving:
1. Drive to the side of the road and park
off the right-of-way on level ground.
2. Turn off the engine and wait 5 minutes
for the oil to drain back into the oil
pan.
3. Inspect the engine oil level (page 8-20).
If it's low, add the appropriate amount
of engine oil while being careful not to
overfill.
4. Start the engine and check the warning
light.
If the light remains illuminated even after
you add oil, stop the engine immediately
and have your vehicle towed to an
Authorized Mazda Dealer.
CAUTION
Do not run the engine if the oil
pressure is low. It could result in
extensive engine damage.
