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.
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 8-24).
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.
