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 clothing 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
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 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
compartment could cause engine
damage or a fire leading to an
unexpected accident.
Hood
▼ Hood
WARNING
Always check that the hood is closed
and securely locked:
A hood that is not closed and securely
locked is dangerous as it could fly open
while the vehicle is moving and block
the driver's vision which could result in
a serious accident.
Do not drive the vehicle with the
Hood-Ajar warning indication
displayed :
Otherwise, the Hood may open
unexpectedly and result in an accident.
▼Opening the Hood

Engine Coolant
▼Inspecting Coolant Level
WARNING
Do not use a match or live flame in
the engine compartment. DO NOT
ADD COOLANT WHEN THE ENGINE
IS HOT:
A hot engine is dangerous. If the
engine has been running, parts of the
engine compartment can become very
hot. You could be burned. Carefully
inspect the engine coolant in the
coolant reservoir, but do not open it.
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.
NOTE
Changing the coolant should be done
by an Authorized Mazda Dealer.
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year ―at the beginning of
the winter season ―and before
traveling where temperatures may drop
below freezing.

Inspect the condition and connections
of all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.

The coolant should be at full in the
radiator and between the F and L
marks on the coolant reservoir when
the engine is cool.

If it is at or near L, add enough coolant
to the coolant reservoir to provide
freezing and corrosion protection and
to bring the level to F.
Securely tighten the coolant reservoir
tank cap after adding coolant.
