Washer Fluid
▼Inspecting Washer Fluid Level
WARNING
Use only windscreen washer fluid or
plain water in the reservoir:
Using radiator antifreeze as washer
fluid is dangerous. If sprayed on the
windscreen, it will dirty the
windscreen, affect your visibility, and
could result in an accident.
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 bonnet 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 bonnet's secondary
latch keeps the bonnet from opening
when the primary latch is released.

▼Inspecting Electrolyte Level
A low level of electrolyte fluid will
cause the battery to discharge quickly.

1. Upper level
2. Lower level
Inspect the electrolyte level at least
once a week. If it is low, remove the
caps and add enough distilled water to
bring the level between the upper and
lower level (illustration).

Do not overfill.
Examine the specific gravity of the
electrolyte with a hydrometer,
especially during cold weather. If it is
low, recharge the battery.
▼Battery Recharging
NOTE
xBefore performing maintenance or
recharging the battery, turn off all
accessories and stop the engine.
xTo disconnect the battery, remove
the negative lead first. Install it last
when connecting the battery.
xBe sure to remove the caps before
recharging the battery.
xDo not quick-charge the battery.
xIf the battery quickly discharges
because, for example, the lights
were left on too long with the engine
off, slow-charge it as required by
battery size and charger capacity.
xIf the battery gradually discharges
because of high electric load while
the vehicle is being used, recharge it
as required by battery size and
charger capacity.

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 expert
repairer (we recommend an
Authorised Mazda Repairer) 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.

amperage rating , and make sure it
fits tightly. If it does not
fit tightly,
have an expert install it. Consult an
expert repairer (we recommend an
Authorised Mazda Repairer).
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.
6. Reinstall the cover and make sure
that it is securely installed.

components do not work and the fuses
in the cabin are normal, inspect the
fuse block under the bonnet.
If a fuse is blown, it must be replaced.
Follow these steps:

1. Make sure the ignition is switched
off, and other switches are
off.
2. Remove the fuse block cover.
3. If any fuse but the MAIN fuse is
blown, replace it with a new one of
the same amperage rating.
