Maintenance
Always keep the jack clean.
Make sure the moving parts are kept
free from dirt or rust.
Make sure the screw thread is
adequately lubricated.
▼ 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. Yo u
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.

2. Put a vehicle with an automatictransaxle in Park (P), a manual
transaxle in Reverse (R) or 1, and turn
off the engine.
3. Turn on the hazard warning flasher.
4. Have everyone get out of the vehicle
and away from the vehicle and traffic.
5. Remove the jack, tool, and spare tire (page 7-3).
6. Block the wheel diagonally opposite the flat tire. When blocking a wheel,
place a tire block both in front and
behind the tire.
NOTE
When blocking a tire, use rocks or
wood blocks of sufficient size if
possible to hold the tire in place.
▼Removing a Flat Tire
WA R N I N G
When jacking-up a vehicle, always shift the
shift lever to 1st or R (manual transaxle
vehicle) or shift the selector lever to P
(automatic transaxle vehicle), apply the
parking brake, and place wheel blocks in
the position diagonally opposed to the
jack:
Changing a
flat tire without using wheel
blocks is dangerous because the vehicle
may move and fall off the jack even with
the shift lever in 1st or R, or the select lever
is in P, which could result in an accident.
1. If your vehicle is equipped with a wheel cover, pry off the wheel cover
with the beveled end of the jack lever.

NOTE
Force the end of the jack lever firmly
between wheel and cover, or removal
will be difficult.

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 injury if the vehicle
were to fall off the jack.
9. Remove the lug nuts by turning themcounterclockwise; 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.
Special key
Antitheft lug nut
To remove an antitheft lug nut
1. Obtain the special key for the antitheft
lug nut.
2. Place the special key on top of the
antitheft lug nut, and be sure to hold
the key square to it. If you hold the key
at an angle, you may damage both key
and nut. Do not use a power impact
wrench.

mounting surfaces of the wheel and
hub, including the hub bolts, with a
cloth.

WA R N I N G
Make sure the mounting surfaces of the
wheel, hub and lug nuts are clean
before changing or replacing tires:
When changing or replacing a tire, not
removing dirt and grime from the
mounting surfaces of the wheel, hub
and hub bolts is dangerous. The lug
nuts could loosen while driving and
cause the tire to come off, resulting in
an accident.

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to w ear abnormally. Here are
some important maintenance points:
▼ Tire Inflation Pressure
Inspect all tire pressu
re monthly (including the spare) when th e tires are cold. Maintain
recommended pressures for the best ride, top handling, and mini mum tire wear. Use the
pressures specified on the vehicle tire information placard or tire label for optimum service.
▼Tire Rotation
To equalize tread wear, rotate the tires every 12,000 km (7,500
miles) at the latest or sooner
if irregular wear develops. Mazda recommends to rotate every 8, 000 km (5,000 miles) to
help increase tire life and d istribute wear more evenly.
Do not include (TEMPORARY USE ONLY)
spare tire in rotation.Forward
Inspect the tires for uneven wear and damage. Abnormal wear is
usually caused by one or a
combination of the following:
Incorrect tire pressure
Improper wheel alignment
Out-of-balance wheel
Severe braking
After rotation, inflate all tire pressures to specification (pa ge 9-10) and inspect the lug nuts
for tightness.
(With tire pressure monitoring system)
After adjusting the tire pressure , initialization of the tire pressure monitoring system is
necessary to make the system operate normally.
Refer to Tire Pressure Monitoring System Initialization on page 4-148.
