before using it.

System)
lBe sure to register the tire pressure
sensor ID signal code whenever tires
or wheels are changed (page 5-30).
1. Park on a level surface off the right-of-
way and firmly set the parking brake.
2. Put a vehicle with an automatic
transmission in Park (P), a manual
transmission 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, and tool (page 7-5).
6. Block the wheel diagonally opposite
the tire to be changed. 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 to hold
the tire in place.
qRemoving a Tire
1. Loosen the lug nuts by turning them
counterclockwise one turn each, but
don't remove any until the tire has been
raised off the ground.
2. Place the jack under the jacking

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.
NOTE
(With Tire Pressure Monitoring
System)
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 5-29.
lBe sure to install the tire pressure
sensors whenever tires or wheels are
replaced. Refer to Tires and Wheels
on page 5-30.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.

You should replace it before the band is
across the entire tread.
qReplacing a Wheel
WARNING
Using a Wrong-Sized Wheel:
Using a wrong-sized wheel is
dangerous. Braking and handling
could be affected, leading to loss of
control and an accident. Always use
wheels of the correct size on your
vehicle.

lWhen 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.
lThe wheels equipped on your
Mazda are specially designed for
installation of 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 5-30.
When replacing a wheel, make sure the
new one is the same as the original factory
wheel in diameter, rim width, and offset.
