Winter Driving
lCarry emergency gear, including tire
chains, window scraper, flares, a small
shovel, jumper cables, and a small bag
of sand or salt.
Ask an Authorized Mazda Dealer to
perform the following precautions:
lHave the proper ratio of antifreeze in
the radiator.
Refer to Engine Coolant on page 8-20.
lInspect the battery and its cables. Cold
reduces battery capacity.
lInspect the ignition system for damage
and loose connections.
lUse washer fluid made with
antifreeze ―but do not use engine
coolant antifreeze for washer fluid
(page 8-23).
lDo not use the parking brake in
freezing weather as it may freeze.
Instead, shift to P with an automatic
transmission and to 1 or R with a
manual transmission. Block the rear
wheels.
lDo not apply excessive force to a
window scraper when removing ice or
frozen snow on the mirror glass and
windshield.
lNever use warm or hot water for
removing snow or ice from windows
and mirrors as it could result in the
glass cracking.
lBraking performance can be adversely
affected if snow or ice adheres to the
brake equipment. If this situation
occurs, drive the vehicle slowly,
releasing the accelerator pedal and
lightly applying the brakes several
times until the brake performance
returns to normal.
q Snow Tires
Use snow tires on all four wheels
Do not 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 (driver's door frame), 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
5-34).

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 5-9) and TCS (page
5-26).
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
ØThe DSC may not operate correctly
unless the following are observed:
ØUse tires of the correct size
specified for your Mazda on all
four wheels.
ØUse tires of the same
manufacturer, brand and tread
pattern on all four wheels.
ØDo not mix worn tires.
Ø The DSC may not operate correctly
when tire chains are used or a
temporary spare tire is installed
because the tire diameter changes.
Ø If 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 is switched
ON. If the TCS or DSC is operating, the
indicator light flashes.
If the light stays on, the TCS or DSC may
have a malfunction and they may not
operate correctly. Take your vehicle to an
Authorized Mazda Dealer.

CAUTION
ØEach 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.
Ø Your vehicle has also been equipped with a TPMS malfunction indicator to
indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for approximately
one minute and then remain continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Ø To avoid false readings, the system samples for a little while before indicating a
problem. As a result it will not instantaneously register a rapid tire deflation or
blow out.
NOTE
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.

Changing a Tire
WARNING
Be sure to follow the directions for
changing a tire:Changing a tire is dangerous if not
done properly. The vehicle can slip off
the jack and seriously injure
someone. No person should place
any portion of their body under a
vehicle that is supported by a jack.
Never allow anyone inside a vehicle
supported by a jack: Allowing someone to remain in a
vehicle supported by a jack is
dangerous. The occupant could cause
the vehicle to fall resulting in serious
injury.
CAUTION
(With Tire Pressure Monitoring
System)
The 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
lMake sure the jack is well lubricated before
using it.
(With Tire Pressure Monitoring System)
lBe sure to register the tire pressure sensor
ID signal code whenever tires or wheels are
changed (page 5-35).
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 if possible to hold the tire in
place.

After rotation, inflate all tire pressures to
specification (page 10-7) 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 reduced if
rotated from side to side.
CAUTION
Limited-Slip Differential system;
don't use the following:
ØTires not of the designated size
Ø Tires of different sizes or types at
the same time
Ø Tires 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.
q Replacing 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.
Replace all four tires at the same time: Replacing just one tire is dangerous.
It could cause poor handling and
poor braking resulting in loss of
vehicle control. Mazda strongly
recommends that you replace all four
tires at the same time.
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
5-34.
lBe sure to install the tire pressure sensors
whenever tires or wheels are replaced.
Refer to Tires and Wheels on page 5-35.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.

NOTE
Tires degrade over time, even when they are
not being used on the road. It is recommended
that tires generally be replaced when they are
6 years or older. Heat caused by hot climates
or frequent high loading conditions can
accelerate the aging process. The period in
which the tire was manufactured (both week
and year) is indicated by a 4-digit number.
Refer to Tire Labeling on page 9-23.
qReplacing a Wheel
WARNING
Always use wheels of the correct size
on your vehicle:
Using a wrong-sized wheel is
dangerous. Braking and handling
could be affected, leading to loss of
control and an accident.
CAUTION
ØA wrong-sized wheel may
adversely affect:
ØTire fit
ØWheel and bearing life
ØGround clearance
ØSnow-chain clearance
ØSpeedometer calibration
ØHeadlight aim
ØBumper height
ØTire Pressure Monitoring
System
ØLimited-Slip Differential System
Ø (With Tire Pressure Monitoring

P215/65R15 95H is an example of a tire size and load index rating. Here is an explanation
of the various components of that tire size and load index rating. Note that the tire size and
load index rating may be different from the example.
P
Indicates a tire that may be installed on cars, SUVs, minivans and light trucks as designated
by the Tire and Rim Association (T&RA).
NOTE
If your tire size does not begin with a letter this may mean it is designated by either ETRTO
(European Tire and Rim Technical Organization) or JATMA (Japan Tire Manufacturing Association).
215
“215 ”is the nominal width of the tire in millimeters. This three-digit number gives the
width in millimeters of the tire from sidewall edge to sidewall edge. In general, the larger
the number, the wider the tire.

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.
lTIRE FAILURE DUE TO UNDER-INFLATION/OVERLOADING/DAMAGE-
