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.
Do not drive with both the ABS warning light and brake warning light
illuminated. Have the vehicle towed to an expert repairer, we recommend an
Authorised Mazda Repairer 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.
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 expert repairer,
we recommend an Authorised Mazda Repairer.
Do not continue driving when the charging system warning light is illuminated
because the engine could stop unexpectedly.
