Maintenance and Care
Owner Maintenance
NOTE
 Always check tire pressure when tires
are cold. Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.
 Underinflation can cause r educed fuel
economy, uneven and accelerated tire
wear, and poor sealing of the tire bead,
which will deform the wheel and cause
separation of tire from rim.
 Overinflation can produce a harsh ride,
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequently needs inflating,
have it inspected.
Tire Rotation
WARNING
Rotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking, rotate the tires every 12,000
km (7,500 miles). However Mazda
recommends to rotate every 8,000 km
(5,000 miles) to help increase tire life
and distribute wear more evenly.
Refer to Scheduled Maintenance on
page 6-4. During rotation, inspect them for correct
balance.
Do not include (TEMPORARY USE ONLY) spare tire in rotation.
Forward
Also, inspect them 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 (page
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 4-126.
CAUTION
Rotate unidirectional tires and radial
tires that have an asymmetrical tread
pattern or studs only from front to rear,
not from side to side. Tire performance
will be reduced if rotated from side to
side.

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
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.
CAUTION
Align the notch on the wheel cover
with the valve stem when installing it.

Do not jack up the vehicle in a position
other than the designated jack-up
position or place any objects on or
under the jack:Jacking up the vehicle in a position
other than the designated jack-up
position or placing objects on or
under the jack is dangerous as it could
deform the vehicle body or the vehicle

accident.
Use only the jack provided with your
Mazda: Using a jack that is not designed for
your Mazda is dangerous. The vehicle
could slip off the jack and seriously
injure someone.
Never place objects under the jack: Jacking the vehicle with an object
under the jack is dangerous. The jack
could slip and someone could be
seriously injured by the jack or the
falling vehicle.
7. Insert the jack lever and attach the lug
wrench to tire jack.

8. Turn the jack handle clockwise and
raise 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 them
counterclockwise; then remove the
wheel and center cap.
Locking Lug Nuts*
If your vehicle has Mazda optional
antitheft wheel lug nuts, one on each
wheel will lock the tires and you must
use a special key to unlock them. This
key will attach to the lug wrench.
Register them 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 the original lug nuts
(which should still be in the vehicle) must
be installed in place of the wheel lock.

WARNING
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 confi guration:
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.

5. (Without À at tire belt)
Store the damaged tire in the trunk/ luggage compartment.
(With À at tire belt)
Open the trunk/luggage compartment mat.

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to wear abnormally. Here are
some important maintenance points:
Tire Inflation Pressure
Inspect all tire pressure monthly (including the spare) when the tires\
are cold. Maintain
recommended pressures for the best ride, top handling, and minimum 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 distribute 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 (page 9-10) and inspect the lug
nuts for tightness.
(With tire pressure monitoring system)
After adjusting the tire pressure, initialization of the tire pressure m\
onitoring system is
necessary to make the system operate normally.
Refer to Tire Pressure Monitoring System Initialization on page 4-126.
CAUTION
Rotate unidirectional tires and radial tires that have an asymmetrical tread pattern or
studs only from front to rear, not from side to side. Tire performance will be weakened if
rotated from side to side.
