Overheating
If the High engine coolant temperature
warning light illuminates, the vehicle
loses power, or you hear a loud knocking
or pinging noise, the engine is probably
too hot.
WARNING
Switch the ignition to 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 the 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 High engine coolant temperature
warning light illuminates:
1. Drive safely to the side of the road and park off the right-of-way. 2. Put a vehicle with an automatic
transaxle in park (P), a manual
transaxle in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is escaping from under the hood or 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 reservoir level.
If it's 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
8-22).
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.

Starting a Flooded Engine
If the engine fails to start, it may be
flooded (excessive fuel in the engine).
Follow this procedure:
(Without Advanced Keyless Entry &
Push Button Start System)
1. If the engine does not start within fiveseconds on the first try, switch the
ignition off, wait ten seconds and try
again.
2. Make sure the parking brake is on.
3. Depress the accelerator all the way and hold it there.
4. Depress the clutch pedal (Manual transaxle) or the brake pedal
(Automatic transaxle).
5. Switch the ignition to START and hold it there ―for up to ten seconds. If the
engine starts, release the key and
accelerator immediately because the
engine will suddenly rev up.
6. If the engine fails to start, crank it without depressing the accelerator ―for
up to ten seconds.
(With Advanced Keyless Entry & Push
Button Start System)
1. If the engine does not start within five seconds on the first try, wait ten
seconds and try again.
2. Make sure the parking brake is on.
3. Depress the accelerator all the way and hold it there. 4. Depress the clutch pedal (Manual
transaxle) or the brake pedal
(Automatic transaxle), then press the
push button start. If the engine starts,
release the accelerator immediately
because the engine will suddenly rev
up.
5. If the engine fails to start, crank it without depressing the accelerator.

Keep all flames, including cigarettes, and sparks away from open battery cells:
Flames and sparks near open battery cells are dangerous. Hydrogen gas, produced
during normal battery operation, could ignite and cause the battery to explode. An
exploding battery can cause serious burns and injuries.
Do not jump-start a frozen battery or one with a low fluid level: Jump-starting a frozen battery or one with a low fluid level is dangerous. It may
rupture or explode, causing serious injury.
Connect the negative cable to a good ground point away from the battery: Connecting the end of the second jumper cable to the negative (
) terminal of the
discharged battery is dangerous.
A spark could cause the gas around the battery to explode and injure someone.
Route the jumper cables away from parts that will be moving: Connecting a jumper cable near or to moving parts (cooling fans, belts) is dangerous.
The cable could get caught when the engine starts and cause serious injury.
CAUTION
Use only a 12 V booster system. You can damage a 12 V starter, ignition system, and
other electrical parts beyond repair with a 24 V power supply (two 12 V batteries in
series or a 24 V motor generator set).
