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.

Cooling system cap Coolant reservoir
Cooling fan
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.
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 reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.

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 isblown.
Normal 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 OUTLET 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.

Replacing the fuses under the hood
If the headlights or other electrical
components do not work and the fuses in
the cabin are normal, inspect the fuse
block under the hood.
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 .
Normal
Blown
WARNING
Do not replace the main fuse by
yourself. Have an Authorized Mazda
Dealer perform the replacement:
Replacing the fuse by yourself is
dangerous because the MAIN fuse is a
high current fuse. Incorrect
replacement could cause an electrical
shock or a short circuit resulting in a
fire.
4. Reinstall the cover and make sure that it is securely installed.

2. Wipe off the remaining detergent usinga cloth soaked in clean water and
wrung out well.
▼Active Driving Display
Maintenance*
The combiner and mirror surface have a
special coating. When cleaning it, do not
use a hard cloth, a cloth with a rough
surface, or cleaning detergent. Use a
fine-textured, soft cloth.
If a chemical solvent
gets on the combiner
or mirror surface, wipe it off immediately.
Otherwise, they could be damaged and the
surface coating could be scratched.
▼ Panel Maintenance
If a panel becomes soiled, wipe it off with
a soft cloth soaked in clean water and
thoroughly wrung out.
If some areas require further cleaning, use
the following procedure:
1. Wipe the soiled ar
ea with a soft cloth
soaked in a mild detergent (approx.
5 %) diluted with water.
2. Wipe off the remaining detergent using a cloth soaked in clean water and
wrung out well.
NOTE
Be particularly careful when cleaning
shiny surface panels and metallic parts
such as plating as they can be scratched
easily.
▼Cleaning the Window Interiors
If the windows become covered with an
oily, greasy, or waxy film, clean them with
glass cleaner. Follow the directions on the
container.
CAUTION

Do not scrape or scratch the inside of the
window glass. It could damage the
thermal filaments.
 When washing the inside of the window
glass, use a soft cloth dampened in
lukewarm water, gently wiping the
thermal
filaments.
Use of glass cleaning products could
damage the thermal filaments.
▼ Cleaning the Floor Mats
Rubber floor mats should be cleaned with
mild soap and water only.
WA R N I N G
Do not use rubber cleaners, such as tire
cleaner or tire shine, when cleaning rubber
floor
mats:
Cleaning the rubber floor mats with rubber
cleaning products makes the floor mats
slippery.
This may cause an accident when
depressing the accelerator, brake, or clutch
(Manual transaxle) pedal or when getting
in or out of the vehicle.
After removing the floor mats for
cleaning, always reinstall them securely
(page 3-41).
