If a Warning Light Turns On or Flashes
Brake System Warning Indication/Warning Light

This warning has the following functions:
Warning light inspection
For an operation check, make sure that the light turns on when the ignition is switched on, and turns off a few seconds later or when the engine is started.
When the light turns on
If the brake system warning light remains illuminated the brake fluid may be low or there could be a problem with the brake system. Park the vehicle in a safe place immediately and contact an expert repairer (we recommend an Authorised Mazda Repairer).
Refer to Inspecting Brake/Clutch Fluid Level (Search).
Do not drive with the brake system warning light illuminated. Contact an expert repairer (we recommend an Authorised Mazda Repairer) 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.
-
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.
-
(With M Hybrid)
When starting the engine, the brake system warning light may turn on and the warning indication may be displayed. In this case, park the vehicle in a safe location and release the brake pedal.
If the brake system warning light/warning indication does not turn off even after parking the vehicle, have the vehicle inspected by an expert repairer (we recommend an Authorised Mazda Repairer).
Electronic 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 simultaneously. The problem is likely to be the electronic brake force distribution system.
Do not drive with both the brake system warning light and ABS 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.
