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
WA R N I N G
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.
▼Opening the Hood
1. With the vehicle
parked, pull the
release handle to unlock the hood.

2. Insert your hand into the hood opening, slide the latch lever to the
left, and lift up the hood.

Engine Coolant
▼Inspecting Coolant Level
WA R N I N G
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 FULL and LOW
marks on the coolant reservoir when the
engine is cool.

If it is at or near LOW, add enough coolant
to the coolant reservoir to provide freezing
and corrosion protec tion and to bring the
level to FULL.
Securely tighten the coolant reservoir tank
cap after adding coolant.

CAUTION
Radiator coolant will damage paint.
Rinse it off quickly if spilled.
 If the “FL22” mark is shown on or near
the cooling system cap, use of FL-22 is
recommended when replacing engine
coolant. Using engine coolant other than
FL-22 may cause serious damage to the
engine and cooling system.

If the coolant reser voir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.
Brake/Clutch Fluid
▼ Inspecting Brake/Clutch Fluid Level
WA R N I N G
If the brake/clutch fluid level is low, have
the brakes inspected:
A low brake/clutch
fluid level is dangerous.
A low level could indicate brake lining wear
or a brake system leak which could cause
the brakes to fail and lead to an accident.
The brakes and clutch draw fluid from the
same reservoir.
Inspect the fluid level in the reservoir
regularly. It should be kept between the
MAX and MIN lines.
The level normally drops with
accumulated distance, a condition
associated with wear of brake and clutch
linings. If it is exce ssively low, have the
brake/clutch system inspected by an
Authorized Mazda Dealer.
