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 8-23).
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.
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.
qParking Brake Reminder
If the parking brake has not been
completely released and the vehicle is
driven at about 5 km/h (3 mph) or faster, a
continuous beep sound will be heard to
notify the driver that the parking brake
has not been released.
qAnti-Lock Brake System (ABS)
The ABS control unit continuously
monitors the speed of each wheel. If one
is about to lock up, the ABS responds by
automatically releasing and reapplying
that wheel's brake.
The driver will feel a slight vibration in
the brake pedal and may hear a chattering
noise from the brake system. This is
normal when the ABS operates. Continue
to depress the brake pedal without
pumping the brakes.

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 with the ignition switched ON
when the engine is not running.
qClearing the Air Inlet
Clear all obstructions such as 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.
NOTE
The air conditioner may be used along with the
heater 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.
qParking 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
indicated in scheduled maintenance (page
8-3). Consult an Authorized Mazda
Dealer for replacement of the cabin air
filter.

Overheating
If the temperature gauge indicates
overheating, the vehicle loses power, or
you hear a loud knocking or pinging
noise, the engine is probably too hot.
WARNING
Switch the ignition to off and
make sure the fan is not running before
attempting to work near the cooling
fan:
Working near the cooling fan when it
is running is dangerous. The fan
could continue running indefinitely
even if the engine has stopped and
the engine compartment temperature
is high. You could be hit by the fan
and seriously injured.
Do not remove either cooling
system caps when the engine and
radiator are hot:
When the engine and radiator are
hot, scalding coolant and steam may
shoot out under pressure and cause
serious injury.
Open the hood ONLY after steam is no
longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.
If the temperature gauge indicates
overheating:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Shift into park (P).3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is
escaping from under the hood or from
the engine compartment.
If steam is coming from the engine
compartment:
Do not go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the hood and start the engine.
If neither coolant nor steam is
escaping:
Open the hood and idle the engine until
it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the
engine temperature will increase.
Stop the engine and call an
Authorized Mazda Dealer.
6. Make sure the cooling fan is operating,
then turn off the engine after the
temperature has decreased.
7. When cool, check the coolant reservoir
level.
If it's low, look for coolant leaks from
the radiator and hoses.
