Brake System Warning Light
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 distribution
system 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 8-13).
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 5-27).

2. Turn off the engine and inspect the
engine oil level (page 8-9). If it’s low,
add oil.
3. Check the light.
If the light remains on even after you add
oil, have your vehicle towed to the nearest
service station or to an Authorized Mazda
Dealer.

Check Engine Light
If this light comes on while driving, the
vehicle may have a problem. It is
important to note the driving conditions
when the light came on and consult an
Authorized Mazda Dealer.
The check engine light may come on in
the following cases:
•The fuel tank level being very low or
approaching empty.
•The engine’s electrical system has a
problem.
•The emission control system has a
problem.
•The fuel-filler cap is missing or not
tightened securely.If the check engine light flashes
continuously, decrease your speed and
consult an Authorized Mazda Dealer as
soon as possible.

ABS Warning Light
The warning light stays on for a few
seconds when the ignition switch is turned
to the ON position.
If the ABS warning light stays on while
you’re driving, the ABS control unit has
detected a system malfunction. If this
occurs, your brakes will function
normally as if the vehicle had no ABS.
Should this happen, consult an Authorized
Mazda Dealer as soon as possible. Don’t run the engine if oil pressure is
low. It could result in extensive engine
damage.
CAUTION
ABS Warning Light and Brake
Warning 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.

Climate Control System

Operating the Climate Control
System
Operate the climate control system with
the engine running.

Clearing the Air Inlet
Clear all obstructions like leaves, snow
and ice from the hood and the air inlet in
the cowling grille to improve the system
efficiency.

Foggy 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.

Outside/Recirculated Air
Position
Use the outside air position in normal
conditions. The recirculated air position
can be used temporarily when driving on
dusty roads or for quick cooling of the
interior.

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.

Not Using for a Long Period
Run the air conditioner at least once a
month to keep internal parts lubricated.

Check the Refrigerant before
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 optional 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.

Replacement 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.
