The following conditions indicate that the
battery power is low:
 y The KEY indicator light (green) À ashes
in the instrument cluster for about 30
seconds after the engine is turned off
(for vehicles with a type A instrument
cluster (page 4-26 ), messages are
displayed in the instrument cluster).




y The system does not operate and
the operation indicator light on the
transmitter does not À ash when the
buttons are pressed.
 


y The system's operational range is
reduced.

Replacing the battery at an Authorized
Mazda Dealer is recommended to prevent
damage to the key. If replacing the battery
by yourself, follow the instruction.

6. Insert a new battery with the positive
pole facing up, and then cover the
battery with the battery cap.


7. Close the cover.


8. Reinsert the auxiliary key.

¾ Be careful not to allow the rubber ring
shown in the fi gure to be scratched or
damaged.

Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inÀ ation pressures and
stay within the recommended load limits
and weight distribution.
WARNING
Using Diff erent Tire Types:
Driving your vehicle with diff erent
types of tires is dangerous. It could
cause poor handling and poor braking;
leading to loss of control.
Except for the limited use of the
temporary spare tire, use only the
same type tires (radial, bias-belted,
bias-type) on all four wheels.

Using Wrong-Sized Tires:
Using any other tire size than what is
specifi ed for the vehicle (page 9-8 )
is dangerous. It could seriously aff ect
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 specifi ed for the
vehicle.

Tire InÀ ation Pressure
WARNING
Always infl ate the tires to the correct
pressure:
Overinfl ation or underinfl ation of tires
is dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-8 .

Use only a Mazda-genuine tire valve
cap:
Use of a non-genuine part is
dangerous as the correct tire air
pressure cannot be maintained if the
tire valve becomes damaged. If the
vehicle is driven under this condition,
the tire air pressure will decrease which
could result in a serious accident. Do
not use any part for the tire valve cap
that is not a Mazda-genuine part.

Inspect all tire pressures monthly when
the tires are cold. Maintain recommended
pressures for the best ride, handling, and
minimum tire wear.
Refer to the speci¿ cation charts (page
9-8 ).
(With tire pressure monitoring system)
After adjusting the tire pressure,
initialization of the tire pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tire Pressure Monitoring System
Initialization on page 4-108 .
N O T E
 


y Always check tire pressure when tires
are cold.
 


y Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.

Maintenance and Care

y UnderinÀ ation can cause reduced fuel
economy, uneven and accelerated tire
wear, and poor sealing of the tire bead,
which will deform the wheel and cause
separation of tire from rim.
 


y OverinÀ ation can produce a harsh ride,
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
  Keep your tire pressure at the correct
levels. If one frequently needs inÀ ating,
have it inspected.

Tire Rotation
WARNING
Rotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking, rotate the tires every 12,000
km (7,500 miles). However Mazda
recommends to rotate every 8,000 km
(5,000 miles) to help increase tire life
and distribute wear more evenly.
Refer to Scheduled Maintenance on
page 6-4 .


During rotation, inspect them for correct
balance.


Do not include (TEMPORARY USE ONLY)
spare tire in rotation.Forward
Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:

 


y Incorrect tire pressure



y Improper wheel alignment



y Out-of-balance wheel



y Severe braking

After rotation, inÀ ate all tire pressures to
speci¿ cation (page 9-8 ) and inspect the
lug nuts for tightness.
(With tire pressure monitoring system)
After adjusting the tire pressure,
initialization of the tire pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tire Pressure Monitoring System
Initialization on page 4-108 .
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.
(With limited-slip diff erential)
Do not use the following:
 


¾ Tires not of the designated size



¾ Tires of diff erent sizes or types at
the same time
 


¾ Tires not suffi ciently infl ated
If these instructions are not followed,
the rotation of the left and right wheels
will be diff erent and will thus apply
a constant load on the limited-slip
diff erential.
This will cause a malfunction.

*Some models.
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.

If a tire wears evenly, a wear indicator will
appear as a solid band across the tread.
Replace the tire when this happens.

New treadTread wear indicator
Worn tread

You should replace the tire before the band
crosses the entire tread.
(With tire pressure monitoring system)
After adjusting the tire pressure,
initialization of the tire pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tire Pressure Monitoring System
Initialization on page 4-108 .
N O T E
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 8-24 .

Replacing 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 aff ected, leading to loss of
control and an accident.

CAUTION
A wrong-sized wheel may adversely
aff ect:




¾ Tire fi t



¾ Wheel and bearing life



¾ Ground clearance



¾ Snow-chain clearance



¾ Speedometer calibration



¾ Headlight aim



¾ Bumper height

y When replacing a wheel, make sure
the new one is the same as the original
factory wheel in diameter, rim width,
and offset (inset/outset).
 


y For details, contact an Authorized
Mazda Dealer.


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 À at spots.
