This warning has the following functions:
Parking brake warning
The light comes on when the parking
brake is applied with the ignition switch
in the START or ON position. It goes off
when the parking brake is fully released.
Low brake fluid level warning/Electronic brake force distributionsystem 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.
Low brake fluid level warning
You may notice that the pedal is harder to
push 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, check the
brake fluid level immediately and add
fluid as required (page 8-16).
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 goes off, have your brake
system inspected as soon as possible.
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 turn the brake system
warning light on.
In this case, the ABS warning light comes
on at the same time (page 5-31).
WARNING
Brake Warning Light:
Driving with the brake system warning
light on 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 on, after
checking that the parking brake is
fully released, have the brakes
inspected immediately. Don't drive
with this light on, and contact an
Authorized Mazda Dealer to have the
brakes inspected as soon as possible.
ABS Warning Light and BrakeWarning Light on at the Same Time:
Driving when the brake system
warning light and ABS warning light
are on at the same time is dangerous.
When both lights are on, the rear
wheels could lock more quickly in an
emergency stop than under normal
circumstances.
Don't drive with both lights on, and
contact an Authorized Mazda Dealer
to have the brakes inspected as soon
as possible.

Operating Tips
qOperating the Climate Control
System
Operate the climate control system with
the engine running.
NOTE
To prevent the battery from being
discharged, do not leave the fan control
dial on for a long period of time when
the engine is not running.
qClearing the Air Inlet
Clear all obstructions like leaves, snow
and ice from the hood and the air inlet in
the cowl grille to improve the system
efficiency.
qFoggy Windows
The windows may fog up easily in humid
weather. Use the climate control system to
defog the windows.
To help defog the windows, operate the
air conditioner to dehumidify the air.
qOutside/Recirculated Air Position
Use the outside air position in normal
conditions. The recirculated air position
should be used only when driving on
dusty roads or for quick cooling of the
interior.
q Parking in Direct Sunlight
If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then run
the climate control system.
qNot Using for a Long Period
Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated.
qCheck the Refrigerant before the
Weather Gets Hot
Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
efficient. Consult an Authorized Mazda
Dealer for refrigerant inspection.
The air conditioner is filled with
HFC134a (R134a), a refrigerant that will
not damage the ozone layer.
If the air conditioner is low on refrigerant
or has a malfunction, consult an
Authorized Mazda Dealer.
qReplacement of the Cabin Air
Filter
If your vehicle is equipped with an air
filter for the air conditioner, it is necessary
to change the filter periodically as
