▼ Tire Pressure Monitoring System
(TPMS) Warning Indication/
Warning Light (Turns on)
If a tire pressure d
ecreases below the
specified air pressure, the TPMS warning
light turns on.
At the same time, a message and the tire
pressure of each tire are displayed on the
multi-information disp lay alternately. In
addition, the tire (s) with low air pressure
is displayed in yellow.
WA R N I N G
Do not drive the vehicle at high speeds if
the TPMS warning light turns on or flashes:
Driving the vehicle at high speeds while the
TPMS warning light is turned on or flashing
is dangerous because the brake
performance and the steering wheel
operability will be reduced. If the vehicle is
driven at high speeds or the brakes are
suddenly applied, it could lead to an
accident. Gradually apply the brakes to
lower the vehicle's speed.
Do not ignore the TPMS warning light
when it is turned on or flashing:
Continuing to drive the vehicle while
ignoring the illumination/flashing of the
TPMS warning light is dangerous because a
tire may burst which could lead to an
accident. Take appropriate measures as
soon as possible.
NOTE
While the TPMS is learning the tire
positions, such as immediately after a tire
position has been changed, the tire
pressure at the tire position prior to it
being changed is displayed until the
system completes the learning. For this
reason, the tire pressures displayed for the
tire positions may be different from the
actual tire pressures at the tire positions.
Action to be taken
Adjust the tire pressu res to the appropriate
pressures.

Tread Wear, Traction and Temperature
Grades
Tr e a d w e a r : The tread wear grade is a
comparative rating based on the wear rate
of the tire when test ed 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.
Te m p e r a t u r e : 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 us ed 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.

Location of the Tire Label(Placard)
▼Location of the Tire Label (Placard)
You will find the tire label containing tire
inflation pressure by tire size and other
important information on the driver's side
B-pillar or on the edge of the driver's door
frame.

SAMPLE
▼Recommended Tire Inflation
Pressure
On the tire label you will find the
recommended tire inflation pressure in
both kPa and psi for th
e tires installed as
original equipment o n the vehicle. It is
very important that th e inflation pressure
of the tires on your vehicle is maintained
at the recommended pressure. You should
check the tire pressure regularly to insure
that the proper inflation pressure is
maintained.
Refer to Tires on page 9-9.
NOTE
Tire pressures listed on the vehicle placard
or tire information label indicate the
recommended cold tire inflation pressure,
measured when the tires are cold, after the
vehicle has been parked for at least 3
hours. As you drive, the temperature in the
tire warms up, increasing the tire pressure.
WA R N I N G
Always check the tire inflation pressures on
a regular basis according to the
recommended tire inflation pressure on the
tire label and in conjunction with the
information in this owner's manual:
Driving your vehicle with under-inflated
tires is dangerous.
Under-inflation is the most common cause
of failures in any kind of tire and may result
in severe cracking, tread separation or
“blowout”, with unexpected loss of vehicle
control and increased risk of injury.
Under-inflation increases sidewall
flexing
and rolling resistance, resulting in heat
buildup and internal damage to the tire. It
results in unnecessary tire stress, irregular
wear, loss of control and accidents. A tire
can lose up to half of its air pressure and
not appear to be flat!
It is impossible to determine whether or not
tires are properly inflated just by looking at
them.
▼ Checking Tire Pressure
1. When you check the air pressure, make
sure the tires are cold ―meaning they
are not hot from driving even a mile.
2. Remove the cap from the valve on one
tire.
3. Firmly press a t ire gauge onto the
valve.
4. Add air to achieve recommended air pressure.
5. If you overfill the tire, release air by
pushing on the metal stem in the center
of the valve. Then recheck the pressure
with your tire gauge.
6. Replace the valve cap.

7. Repeat with each tire, including thespare.
NOTE
Some spare tires require higher
inflation pressure.
8. Visually inspect the tires to make sure
there are no nails or other objects
embedded that could poke a hole in the
tire and cause an air leak.
9. Check the sidewalls to make sure there are no gouges, cuts, bulges, cracks or
other irregularities.

Tire Maintenance
▼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 p
ressures specified on
the vehicle tire information placard or tire
label for optimum service.
▼ Tire Rotation
To equalize tread wear, rotate the tires
every 16,000 km (10,000 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.
1. Forward
Do not include (TEMPORARY USE
ONLY) spare tire in rotation.

Inspect the tires fo
r uneven wear and
damage. Abnormal wear is usually caused
by one or a combinati on 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- 9) 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.
▼ Replacing a Tire
WA R N I N G
Always use tires that are in good condition:
Driving with worn tires is dangerous.
Reduced braking, steering, and traction
could result in an accident.
If a tire wears evenly, a wear indicator will
appear as a solid band across the tread.
Replace the tire when this happens.
1. New tread
2. Worn tread
3. Tread wear indicator

You should replace the tire before the band
crosses the entire tread.

Vehicle Loading
▼Vehicle Loading
WA R N I N G
Do not tow a trailer with this vehicle:
Towing a trailer with this vehicle is
dangerous because it has not been
designed to tow a trailer and doing so will
affect
the drive system which could result in
vehicle damage.
This section will guide you in the proper
loading of your vehicle, to keep your
loaded vehicle weigh t within its design
rating capability. Properly loading your
vehicle will provide maximum return of
vehicle design performance. Before
loading your vehicle, familiarize yourself
with the following terms for determining
your vehicle's weight ratings, from the
vehicle's Safety Certification Label and
Tire and Load Information Label:
WA R N I N G
Overloaded Vehicle:
Overloading a vehicle is dangerous. The
results of overloading can have serious
consequences in terms of passenger safety.
Too much weight on a vehicle's suspension
system can cause spring or shock absorber
failure, brake failure, handling or steering
problems, irregular tire wear, tire failure or
other damage.
Overloading makes a vehicle harder to
drive and control. It also increases the
distance required for stopping. In cases of
serious overloading, brakes can fail
completely, particularly on steep grades.
The load a tire will carry safely is a
combination of the size of the tire, its load
range, and corresponding inflation
pressure.
Never overload the vehicle and always
observe the vehicle's weight ratings from
the vehicle's Safety Certification and Tire
and Load Information labels.
Base Curb Weight is the weight of the
vehicle including a full tank of fuel and
all standard equipment. It does not
include passengers, cargo, or optional
equipment.

Vehicle Curb Weight is the weight of
your new vehicle when you picked it up
from your dealer plus any aftermarket
equipment.
