WA R N I N G
Do not perform maintenance work if you lack sufficient knowledge and experience or the
proper tools and equipment to do the work. Have maintenance work done by a qualified
technician:
Performing maintenance work on a vehicle is dangerous if not done properly. You can be
seriously injured while performing some maintenance procedures.
If you must run the engine while working under the hood, make certain that you remove all
jewelry (especially rings, bracelets, watches, and necklaces) and all neckties, scarves, and
similar loose clothing before getting near the engine or cooling fan which may turn on
unexpectedly:
Working under the hood with the engine running is dangerous. It becomes even more
dangerous when you wear jewelry, loose clot hing or have long hair or a long beard.
Either can become entangled in moving parts and result in injury.
Pull over to a safe location, then switch the ignition 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 runn ing 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 leave items in the engine compartment:
After you have finished checking or doing servicing in the engine compartment, do not forget
and leave items such as tools or rags in the engine compartment.
Tools or other items left in the engine comp artment could cause engine damage or a fire
leading to an unexpected accident.

Overheating
If the temperature gauge indicates
overheating or the high engine coolant
temperature warning light turns on, the
vehicle loses power, or you hear a loud
knocking or pinging noise, the engine is
probably too hot.
WA R N I N G
Pull over to a safe location, then switch
the ignition 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 cap 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 or the high engine coolant
temperature warning light turns on:

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 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 level.If it is low, look for coolant leaks from
the radiator and hoses.

If you find a leak or other damage, or if
coolant is still leaking:
Stop the engine and call an Authorized
Mazda Dealer.

If you find no problems, the engine is
cool, and no leaks are obvious:
Carefully add coolant as required (page
6-22).
CAUTION
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be
seriously damaged unless repairs are
made. Consult an Authorized Mazda
Dealer.

Mazda Dealer.
CAUTION
Do not continue driving when the charging system warning light is illuminated be‐
cause the engine could stop unexpectedly.
Engine Oil Warning Light This warning light indicates low engine oil pressure.
CAUTION
Do not run the engine if the oil pressure is
low. Otherwise, it could result in extensive
engine damage.
If the light illuminates or the w arning indication is displayed while driving:
1. Drive to the side of the road and park off the right-of-way o n level ground.
2. Turn off the engine and wait 5 minutes for the oil to drain b ack into the oil pan.
3. Inspect the engine oil level (p age 6-21). If it's low, add the appropriate amount of
engine oil while being careful not to overfill.
CAUTION
Do not run the engine if the oil level is low. Otherwise, it could result in extensive
engine damage.
4. Start the engine and check the warning light.

If the light remains illuminated even though the oil level is normal or after adding oil,
stop the engine immediately and have your vehicle towed to an Authorized Mazda
Dealer.
(Red)
High Engine Coolant
Temperature Warning Indication/Warning Light The light flashes when the engine
coolant temperature is extremely high, and illumi‐
nates when the engine coolant temperature increases further.
Handling Procedure
Flashing light
Drive slowly to reduce engine load until you can find a safe pl ace to stop the vehicle
and wait for the engine to cool down.
Illuminated light
This indicates the possibility of overheating. Park the vehicle in a safe place immedi‐
ately and stop the engine.
Refer to Overheating on page 7-23.
CAUTION
Do not drive the vehicle with the high engine coolant temperature warning light illumi‐
nated. Otherwise, it could resu lt in damage to the engine.
