qSnow Tires
Use snow tires on all four wheels
Don't go faster than 120 km/h (75 mph)
while driving with snow tires. Inflate
snow tires 30 kPa (0.3 kgf/cm
2, 4.3 psi)
more than recommended on the tire
pressure label (rear door on the driver's
side), but never more than the maximum
cold-tire pressure shown on the tires.
Your vehicle is originally equipped with
summer tires designed for optimum
traction on wet and dry roads. If your
vehicle is to be used on snow and ice
covered roads, Mazda recommends that
you replace the tires originally equipped
on your vehicle with snow tires during the
winter months.
WARNING
Use only the same size and type tires
(snow, radial, or non-radial) on all
four wheels:
Using tires different in size or type is
dangerous. Your vehicle's handling
could be greatly affected and result in
an accident.
CAUTION
Check local regulations before using
studded tires.
NOTE
If your vehicle is equipped with the tire
pressure monitoring system, the system
may not function correctly when using
tires with steel wire reinforcement in
the sidewalls (page 5-30).
qTire Chains
Check local regulations before using tire
chains.
CAUTION
lChains may affect handling.
lDo not go faster than 50 km/h (30
mph) or the chain manufacturer's
recommended limit, whichever is
lower.
lDrive carefully and avoid bumps,
holes, and sharp turns.
lAvoid locked-wheel braking.
lDo not use chains on a temporary
spare tire; it may result in damage to
the vehicle and to the tire. Your
vehicle is not equipped with a
factory installed temporary spare
tire.
lDo not use chains on roads that are
free of snow or ice. The tires and
chains could be damaged.
lChains may scratch or chip
aluminum wheels.
NOTE
If your vehicle is equipped with the tire
pressure monitoring system, the system
may not function correctly when using
tire chains.
Install the chains on the rear tires.
Do not use chains on the front tires.
Use only SAE Class“S”chains, and make
sure they fit.

Dynamic Stability Control
(DSC)
í
The Dynamic Stability Control (DSC)
automatically controls braking and engine
torque in conjunction with systems such
as ABS and TCS to help control side slip
when driving on slippery surfaces, or
during sudden or evasive maneuvering,
enhancing vehicle safety.
Refer to ABS (page 5-7) and TCS (page
5-23).
WARNING
Do not rely on the dynamic stability
control as a substitute for safe driving:
The dynamic stability control (DSC)
cannot compensate for unsafe and
reckless driving, excessive speed,
tailgating (following another vehicle
too closely), and hydroplaning
(reduced tire friction and road contact
because of water on the road surface).
You can still have an accident.
CAUTION
lThe DSC may not operate correctly
unless the following are observed:
lUse tires of the correct size
specified for your Mazda on all
four wheels.
lUse tires of the same
manufacturer, brand and tread
pattern on all four wheels.
lDo not mix worn tires.
lThe DSC may not operate correctly
when tire chains are used or a
temporary spare tire is installed
because the tire diameter changes.
lIf repair or replacement of the
steering or other surrounding
equipment is necessary, have it done
at an Authorized Mazda Dealer. If
the center position of the steering
deviates, the DSC may not operate
correctly because there is a sensor in
the steering which detects driving
conditions.
qTCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition switch is turned
to the ON position. If the TCS or DSC is
operating, the indicator light flashes.

Tire Pressure Monitoring
System
í
The tire pressure monitoring system
(TPMS) monitors the pressure for each
tire.
If tire pressure is too low in one or more
tires, the system will inform the driver via
the warning light in the instrument panel
and by the warning beep sound.
The tire pressure sensors installed on each
wheel send tire pressure data by radio
signal to the receiver unit in the vehicle.
Tire pressure sensors
NOTE
When the ambient temperature is low
due to seasonal changes, tire
temperatures are also lower. If the tire
temperature lowers, the air pressure
lowers as well, and the TPMS warning
light illuminates more frequently.
Inspect the tire pressure dailybefore
driving, and check the tire pressures
monthly with a tire pressure gauge.
When checking the tire pressures, use
of a digital tire pressure gauge is
recommended.TPMS does not alleviate your need to
check the pressure and condition of all
four tires before you drive each day.
CAUTION
lEach tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on a
significantly under-inflated tire
causes the tire to overheat and can
lead to tire failure. Under-inflation
also reduces fuel efficiency and tire
tread life, and may affect the
vehicle's handling and stopping
ability.
Please note that the TPMS is not a
substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct tire
pressure, even if under-inflation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.

CAUTION
lTo avoid damage to the temporary
spare tire or to the vehicle, observe
the following precautions:
lDo not exceed 80 km/h (50 mph).lAvoid driving over obstacles.
Also, do not drive through an
automatic car wash. This tire's
diameter is smaller than a
conventional tire's, so the ground
clearance is reduced about 25 mm
(1 in).
lDo not use a tire chain on this tire
because it won't fit properly.
lDo not use your temporary spare
tire on any other vehicle; it has
been designed only for your
Mazda.
lUse only one temporary spare tire
on your vehicle at the same time.
(With limited slip differential)
When using the temporary spare tire on
the rear axle, replace it with a standard
tire as soon as possible. The size
difference between the spare and the
standard tire will cause the limited slip
differential to malfunction.
NOTE
(With Tire Pressure Monitoring
System)
A tire pressure sensor is not installed to
the temporary spare tire. The warning
light will flash continuously while the
temporary spare tire is being used (page
5-28).
Instant Mobility System
(IMS) Emergency Flat
Tire Repair Kit
The IMS emergency flat tire repair kit
included with your Mazda is for a
temporary repair of a slightly damaged
flat tire resulting from running over nails
or similar sharp objects on the road
surface.
NOTE
Your vehicle is not equipped with a
spare tire. In the event of a flat tire, use
the emergency flat tire repair kit to
repair the tire temporarily. When doing
the repair, refer to the instructions
included in the emergency flat tire
repair kit. After temporarily repairing a
tire with the emergency flat tire repair
kit, take your vehicle to an Authorized
Mazda Dealer to have the tire replaced.

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.
WARNING
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.
Use all radial, all bias-belted, or all
bias-type tires.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for your Mazda (page 10-6)
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 your
Mazda.
qTire Inflation Pressure
WARNING
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 specification charts on page
10-6.The Tire Pressure Monitoring System
í
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, handling, and minimum
tire wear.
When checking the tire pressures, use of a
digital tire pressure gauge is
recommended.
Refer to the specification charts (page
10-6).

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
Always use tires that are in good
condition:
Driving with worn tires is dangerous.
Reduced braking, steering, and
traction could result in an accident.
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 5-30.
lBe sure to install the tire pressure
sensors whenever tires or wheels are
replaced.
Refer to Tires and Wheels on page
5-30.

Tread Wear, Traction and Temperature Grades
Tread wear:The tread wear grade is a comparative rating based on the wear rate of the tire
when tested under controlled conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half (1 1/2) times as well on the
government course as a tire graded 100.
Traction:The traction grades, from highest to lowest are AA, A, B, and C. The grades
represent the tire's ability to stop on wet pavement as measured under controlled conditions
on specified government test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance.
Temperature:The temperature grades are A (the highest), B and C, representing the tire's
resistance to the generation of heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory test wheel.
Snow Tires
In some heavy snow areas, local governments may require true snow tires, those with very
deeply cut tread. These tires should only be used in pairs or placed on all four wheels.
Make sure you purchase snow tires that are the same size and construction type as the other
tires on your vehicle.
SAFETY WARNING
The following safety warning appears on the tire's sidewall.
SERIOUS INJURY MAY RESULT FROM:
lEXPLOSION OF TIRE/RIM ASSEMBLY DUE TO IMPROPER MOUNTING-
MATCH TIRE DIAMETER TO RIM DIAMETER; NEVER EXCEED 40 psi (275 kPa)
TO SEAT BEADS-ONLY SPECIALLY TRAINED PERSONS SHOULD MOUNT
TIRES.
