Keep the top clean and dry.
Keep terminals and connections clean,
tight, and coated with petroleum jelly or
terminal grease.
Rinse off spilled electrolyte immediately
with a solution of water and baking
soda.
If the vehicle will
not be used for an
extended time, disconnect the battery
cables and charge the battery every 6
weeks.
▼ Battery Replacement

battery replacement purchase.
Key Battery Replacement
If the buttons on the transmitter are
inoperable and the operation indicator
light does not flash, the battery may be
dead.
Replace with a new battery before the
transmitter becomes unusable.
CAUTION

Make sure the battery is installed
correctly. Battery leakage could occur if it
is not installed correctly.
 When replacing the battery, be careful
not to touch any of the internal circuitry
and electrical terminals, bend the
electrical terminals, or get dirt in the
transmitter as the transmitter could be
damaged.
 There is the danger of explosion if the
battery is not correctly replaced.
 Dispose of used batteries according to
the following instructions.
 Insulate the plus and minus terminals
of the battery using cellophane or
equivalent tape.

3. Pull the fuse straight out with the fusepuller provided on the fuse block
located in the eng ine compartment.
4. Inspect the fuse and replace it if it is
blown.
Normal Blown
5. Insert a new fu
se of the same
amperage rating, and make sure it fits
tightly. If it does not fit tightly, have an
expert install it. We recommend 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 fu ses 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.

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.

▼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 rein stall them securely
(page 3-45).

▼Spare Tire
Your Mazda has a temporary spare tire.
The temporary spare tire is lighter and
smaller than a conventional tire, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tires should
NEVER be used for long drives or
extended periods.
WA R N I N G
Do not install the temporary spare tire on
the front wheels (driving wheels):
Driving with the temporary spare tire on
one of the front driving wheels is
dangerous. Handling will be
affected. You
could lose control of the vehicle, especially
on ice or snow bound roads, and have an
accident. Move a regular tire to the front
wheel and install the temporary spare tire
to the rear.
CAUTION
 When using the temporary spare tire,
driving stability may decrease compared
to when using only the conventional tire.
Drive carefully.
 To avoid damage to the temporary spare
tire or to the vehicle, observe the
following precautions:
 Do not exceed 80 km/h (50 mph).
 Avoid driving over obstacles. Also, do
not drive through an automatic car
wash. This tire's diameter is smaller
than a conventional tire, so the ground
clearance is reduced.
 Do not use a tire chain on this tire
because it will not fit properly.
Do not use your temporary spare tire
on any other vehicle, it has been
designed only for your Mazda.
 Use only one temporary spare tire on
your vehicle at the same time.
To remove the spare tire
1. Remove the trunk mat.

2. Turn the spare tire hold-down boltcounterclockwise.

If you are unsure of how tight the nuts
should be, have them inspected at an
Authorized Mazda Dealer.
Nut tightening torque
N·m (kgf·m, ft·lbf) 108―147 (12―14,
80―108)
WA R N I N G
Always securely and correctly tighten
the lug nuts:
Improperly or loosely tightened lug
nuts are dangerous. The wheel could
wobble or come off. This could result in
loss of vehicle control and cause a
serious accident.
Be sure to reinstall the same nuts you
removed or replace them with metric
nuts of the same configuration:
Because the wheel studs and lug nuts
on your Mazda have metric threads,
using a non-metric nut is dangerous.
On a metric stud, it would not secure
the wheel and would damage the stud,
which could cause the wheel to slip off
and cause an accident.
6. (Without flat tire belt)
Store the damaged tire in the trunk.
(With flat tire belt)
Open the trunk mat.
7. Remove the belt for securing the flat tire.
8. Put the flat tire into the trunk on the
left and toward the back.

9. Fold the seat back f orward on the right
side of the rear seat.
10. Thread the belt thro ugh the rear seat as
shown in the figure.

11. Thread the buckle through the wheel as
shown in the figure and secure it so
that the buckle does not contact the
wheel.

12. Thread the belt through the buckle,then pull the belt end to secure the flat
tire.

13. Return the seat back on the right sideof the rear seat to it s original position.
14. Remove the tire blocks and store the
tools and jack.
15. Check the inflation pressure. Refer to Tires on page 9-9.
16. Have the flat tire repaired or replaced as soon as possible.
WA R N I N G
Do not drive with any tires that have
incorrect air pressure:
Driving on tires with incorrect air pressure
is dangerous. Tires with incorrect pressure
could affect handling and result in an
accident. When you check the regular tires'
air pressure, check the spare tire, too.
NOTE
To prevent the jack and tool from rattling,
store them properly.
