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.
CAUTION
In addition, the effectiveness of the
braking may diminish so you may
need to depress the brake pedal more
strongly than normal to stop the
vehicle.
qIf the ABS warning light illuminates
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.
lThe brake assist system does not operate
while the ABS warning light is illuminated.
qIf the brake system warning light
and the ABS warning light
illuminate simultaneously
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 simultaneously. The
problem is likely to be the electronic
brake force distribution system.
