Seat Belt Warning Light/Beep
If the driver’
s seat belt is not fastened
when the ignition switch is turned to the
ON position, a beep will sound for about
6 seconds and the seat belt warning light
will remain on until the belt is fastened.
If the system does not operate correctly,
consult an Authorized Mazda Dealer.

Charging System Warning Light
This warning light indicates a malfunction
of the alternator or of the charging system.
If the light comes on while driving:
1. Drive to the side of the road and park
off the right-of-way.
2. Turn off the engine. Inspect the alternator drive belt for looseness and
breakage.
3. If it ’s OK, the charging system has a
problem. Consult an Authorized
Mazda Dealer as soon as possible.
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, 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 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.

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 drive with a loose or broken
alternator belt. The engine could
overheat because this belt also drives
the water pump.
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.

In Case of an Emergency
Form No. 8Q42-EA-01F
Overheating
If the temperature gauge indicates
overheating, you experience power loss,
or you hear a loud knocking or pinging
noise, the engine is probably too hot.
If this happens:
1. Drive safely to the side of the road and park off the right-of-way.
2. Put a vehicle with an automatic transmission in park (P), a manual
transmission in neutral.
Apply the parking brake.
3. Turn off the air conditioner. 4. Check whether coolant or steam is
escaping from under the hood or from
the engine compartment.
If steam is coming from the engine
compartment, don ’t go near the front
of the vehicle. Stop the engine. Then
turn the ignition switch to the ON
position without starting the engine.
The radiator cooling fans will start to
cool the engine.
If neither coolant nor steam is
escaping, open the hood and idle the
engine until it cools. If this doesn ’t
lower the temperature, stop the engine
and let it cool.
5. Visually inspect the alternator/water pump drive belt for looseness and
breakage and all cooling hose
connections for leaks. If the belt is
broken or coolant is leaking, call an
Authorized Mazda Dealer for
assistance.
6. If the drive belt is OK, the engine is cool, and no coolant leaks are obvious,
inspect the coolant level. Carefully add
coolant as required (page 8-15).
Overheating
Steam from Overheated Engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you. Open the hood
ONLY after steam is no longer
escaping from the engine.
