To get the best service from a battery:
•Keep it securely mounted.
•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 six
weeks.
▼ Battery Replacement
Contact an Authorized Mazda Dealer for a
battery replacement purchase.

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

Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WA R N I N G
Using Different Tire Types:
Driving your vehicle with different types of
tires is dangerous. It could cause poor
handling and poor braking; leading to loss
of control.
Except for the limited use of the temporary
spare tire, use only the same type tires
(radial, bias-belted, bias-type) on all four
wheels.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for the vehicle (page 9-7) is
dangerous. It could seriously affect ride,
handling, ground clearance, tire clearance,
and speedometer calibration. This could
cause you to have an accident. Use only
tires that are the correct size specified for
the vehicle.
▼ Tire Inflation Pressure
WA R N I N G
Always
inflate the tires to the correct
pressure:
Overinflation or underinflation of tires is
dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-7.

8. Turn the jack handle clockwise andraise the vehicle high enough so that
the spare tire can be installed. Before
removing the lug nuts, make sure your
Mazda is firmly in position and that it
cannot slip or move.

WARNING
Do not jack up the vehicle higher than
is necessary:
Jacking up the vehicle higher than is
necessary is dangerous as it could
destabilize the vehicle resulting in an
accident.
Do not start the engine or shake the
vehicle while it is jacked up:
Starting the engine or shaking the
vehicle while it is jacked up is
dangerous as it could cause the vehicle
to fall off the jack resulting in an
accident.
Never go under the vehicle while it is
jacked up:
Going under the vehicle while it is
jacked up is dangerous as it could result
in death or serious in jury if the vehicle
were to fall off the jack.
9. Remove the lug nuts by turning them counterclockwise; then remove the
wheel and center cap.
▼Locking Lug Nuts*
If your vehicle has Mazda optional
antitheft wheel lug nuts, each wheel will
have one locking lug nut that locks the
wheel and tire, and you must use a special
key to unlock the locking lug nut. This key
is stored in the glove compartment.
Register the key and l
ug nuts with the lock
manufacturer by filling out the card
provided in the glove compartment and
mailing it in the accompanying envelope.
If you lose this key, consult an Authorized
Mazda Dealer or use the lock
manufacturer's order form, which is with
the registration card.
Accessory wheel locks cannot be used on
steel wheels. This includes situations when
the spare tire is installed. If the spare tire is
installed, one of th e original lug nuts
(which should still be in the vehicle) must
be installed in place of the wheel lock.
