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.

Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.
The top of the float should be between F
and E.

Use plain water if washer fluid is
unavailable.
But use only washer fluid in cold weather
to prevent it from freezing.
NOTE
Front and rear washer fluid is supplied
from the same reservoir.
Body Lubrication
▼Body Lubrication
All moving points of the body, such as
door and hood hinges and locks, should be
lubricated each time the engine oil is
changed. Use a nonfreezing lubricant on
locks during cold weather.

Make sure the hood's secondary latch
keeps the hood from opening when the
primary latch is released.

Fuses
▼Fuses
Your vehicle's electrical system is
protected by fuses.

If any lights, accessories, or controls do
not work, inspect the appropriate circuit
protector. If a fuse has blown, the inside
element will be melted.

If the same fuse blows
again, avoid using
that system and consult an Authorized
Mazda Dealer as soon as possible.
▼ Fuse Replacement
Replacing the fuses on the vehicle's left
side
If the electrical system does not work, first
inspect the fuses on the vehicle's left side.

1. Make sure the ignition is switched off,
and other switches are off.
2. Open the fuse panel cover.
3. Pull the fuse straight out with the fuse puller provided on the fuse block
located in the engine compartment.
4. Inspect the fuse and replace it if it is
blown.
1. Normal
2. Blown

5. Insert a new fuse of the same amperage rating, and make sure it fits
tightly. If it does not fit tightly, have an
expert install it. Consult an Authorized
Mazda Dealer.
If you have no spare fuses, borrow one
of the same rating from a circuit not
essential to vehicle operation, such as
the audio or accessory socket circuit.
CAUTION
Always replace a fuse with a genuine
Mazda fuse or equivalent of the same
rating. Otherwise you may damage the
electric system.
