qLocking Lug Nuts
If your vehicle has 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 is attached
to the lug wrench and is stored with the
spare tire. Register them with the lock
manufacturer by filling out the card
provided in the glove box and mailing it
in the accompanying envelope. If you lose
your key, consult an Authorized Mazda
Dealer or use the lock manufacturer's
order form, which is with the registration
card.

WARNING
Metric Studs and Lug Nuts:
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. Be sure to
reinstall the same nuts you removed or
replace them with metric nuts of the
same configuration.
Incorrect Tire Air Pressure:
Driving on tires with incorrect air
pressure is dangerous. Tires with
incorrect pressure could affect
handling and result in an accident.
Don't drive with any tires that have
incorrect air pressure.
NOTE
To prevent the jack and tool from
rattling, store them properly.

Towing Description
We recommend that towing be done only
by an Authorized Mazda Dealer or a
commercial tow-truck service.
Proper lifting and towing are necessary to
prevent damage to the vehicle.
Government and local laws must be
followed.
A towed vehicle usually should have its
rear wheels off the ground. If excessive
damage or other conditions prevent this,
use wheel dollies.
Wheel dollies
CAUTION
Don't tow the vehicle pointed forward
with driving wheels on the ground. This
may cause internal damage to the
transmission.
CAUTION
Don't tow with sling-type equipment.
This could damage your vehicle. Use
wheel-lift or flatbed equipment.

CAUTION
If the tiedown eyelet is not securely
tightened, it may loosen or disengage
from the bumper when tying down the
vehicle. Make sure that the tiedown
eyelet is securely tightened to the
bumper.
Recreational Towing
An example of“recreational towing”is
towing your vehicle behind a motorhome.
The transmission is not designed for
towing this vehicle on all 4 wheels.
When doing recreational towing refer to
“Towing Description”(page 7-25) and
“Tiedown Hooks”(page 7-26) and
carefully follow the instructions.

The Tire Pressure Monitoring Systemí
does not alleviate the need to check the
tire condition every day, including
whether the tires all look inflated properly.
Inspect all tire pressure monthly
(including the spare
í) when the tires are
cold. Maintain recommended pressures
for the best ride, top handling, and
minimum tire wear.
Refer to the specification charts (page
10-6).
NOTE
lAlways check tire pressure when
tires are cold.
lWarm tires normally exceed
recommended pressures. Don't
release air from warm tires to adjust
the pressure.
lUnderinflation can cause reduced
fuel economy and poor sealing of the
tire bead, which will deform the
wheel and cause separation of tire
from rim.
lOverinflation can produce a harsh
ride 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.
qTire Rotation
To equalize tread wear, rotate the tires
every 12,000 km (7,500 miles)/8,000
km
*(5,000 miles) or sooner if irregular
wear develops. During rotation, inspect
them for correct balance.
* Unique driving conditions for U.S.A.,
Canada and Puerto Rico
NOTE
Because your vehicle is not equipped
with a spare tire, you cannot do a tire
rotation safely with the jack that comes
with your vehicle. Have an Authorized
Mazda Dealer perform tire rotation.

Forward
Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:
lIncorrect tire pressure
lImproper wheel alignment
lOut-of-balance wheel
lSevere braking
After rotation, inflate all tire pressures to
specification (page 10-6) and inspect the
lug nuts for tightness.
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.
CAUTION
Limited-Slip Differential system;
don't use the following:
lTires not of the designated size
lTires of different sizes or types at the
same time
lTires not sufficiently inflated
If these instructions aren't followed, the
rotation of the left and right wheels will
be different and will thus apply a
constant load on the limited-slip
differential.
This will cause a malfunction.
qReplacing a Tire
WARNING
Worn Tires:
Driving with worn tires is dangerous.
Reduced braking, steering, and
traction could result in an accident.
Always use tires that are in good
condition.
CAUTION
(With Tire Pressure Monitoring
System)
When replacing/repairing the tires or
wheels or both, have the work done by
an Authorized Mazda Dealer, or the tire
pressure sensors may be damaged.

lWhen tires with steel wire
reinforcement in the sidewalls are
used, the system may not function
correctly even with a genuine wheel.
Refer to System Error Activation on
page 5-27.
lBe sure to install the tire pressure
sensors whenever tires or wheels are
replaced. Refer to Tires and Wheels
on page 5-28.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.

Worn tread
You should replace it before the band is
across the entire tread.
qTemporary Spare Tire
Your Mazda is not equipped with a spare
tire. If you require a spare tire, consult an
Authorized Mazda Dealer.
Inspect the temporary spare tire at least
monthly to make sure it's properly inflated
and stored.
The temporary spare tire is easier to
handle because of its construction. It is
lighter and smaller than a conventional
tire and should be used only for an
emergency and only for a short distance.
Use the temporary only until the
conventional tire is repaired, which should
be as soon as possible.
Maintain its pressure at 420 kPa (4.2 kgf/
cm
2or bar, 60 psi).
CAUTION
lDon't use your temporary spare tire
rim with a snow tire or a
conventional tire. Neither will
properly fit and could damage both
tire and rim.
lThe temporary spare tire has a tread
life of up to 5,000 km (3,000 miles),
depending on road conditions and
driving habits.
lThe temporary spare tire is for
limited use, however, if the tread
wear solid-band indicator appears,
replace the tire with the same type of
temporary spare (page 8-30).

Dealer, or the tire pressure sensors
may be damaged.
lThe wheels equipped on your
Mazda are specially designed for
installation the tire pressure
sensors. Do not use non-genuine
wheels, otherwise it may not be
possible to install the tire pressure
sensors.
NOTE
Be sure to install the tire pressure
sensors whenever tires or wheels are
replaced. Refer to Tires and Wheels on
page 5-28.
When replacing a wheel, make sure the
new one is the same as the original factory
wheel in diameter, rim width, and offset.
Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.
