WARNING
Remove the key only when the vehicle
is parked:
Removing the key from the ignition
switch while the vehicle is moving is
dangerous. Removing the key allows
the steering wheel to lock. You will
lose steering control and a serious
accident could occur. (For vehicles
equipped with the advanced key, the
steering wheel locks when the starter
knob is turned to the LOCK position.)
Before leaving the driver's seat, always
put the key or start knob to LOCK
position, set the parking brake and
make sure the shift lever is in P:
It is important to place the key or
start knob in the LOCK position even
if you are not removing the key from
the ignition or leaving the vehicle.
Leaving the key in other positions
will disable some of the vehicle
security systems and run the battery
down.
Leaving the driver's seat without
putting the ignition switch in LOCK
position, setting the parking brake
and shifting the shift lever to P is
dangerous. Unexpected vehicle
movement could occur. This could
cause an accident.
NOTE
If turning the key is difficult, jiggle the steering
wheel from side to side.
Leaving the key or start knob in any position
but LOCK position also disables some of the
security features and may run the battery
down.
ACC (Accessory)
The steering wheel unlocks and some
electrical accessories will operate.
ON
This is the normal running position after
the engine is started. The warning lights
(except brakes) should be inspected
before the engine is started (page 5-43).
NOTE
When the ignition switch is turned to the ON
position, the sound of the fuel pump motor
operating near the fuel tank can be heard. This
does not indicate an abnormality.
NOTE
Vibration of the brake pedal may be felt when
the ignition switch is turned to the ON
position, however, this is a normal operation of
the DSC/RSC and does not indicate an
abnormality.
START
The engine is started in this position. It
will crank until you release the key; then
it returns to the ON position. The brake
warning light can be checked after the
engine is started (page 5-43).
qIgnition Key Reminder
If the ignition switch is in the LOCK or
ACC position with the key inserted, a
continuous beep sound will be heard
when the driver's door is opened.

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 switch
in the START or ON position. 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 switch in the
ON position 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.
