Driving Your Mazda
Warning/Indicator Lights and Beeps
Form No. 8R09-EA-02G

Charging System Warning Light
This warning light comes on when the
ignition switch is turned to the ON
position and goes off when the engine is
started.
If the warning light comes on while
driving, it indicates a malfunction of the
alternator or of the charging system.
Drive to the side of the road and park off
the right-of-way. Consult an Authorized
Mazda Dealer.
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 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 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.
WARNING
Don't continue driving when the
charging system warning light is
illuminated.

In Case of an Emergency
Form No. 8R09-EA-02G
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.
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.
