6 –41 Maintenance and Care
Owner Maintenance
TiresFor 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.
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
specified for the vehicle (page 9-8 )
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 the
vehicle. Tire 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 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 specification 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 .
NOTE 
Always check tire pressure when tires
are cold. 
Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.

6 –42 Maintenance and Care
Owner Maintenance 
Underinflation 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. 
Overinflation 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 inflating,
have it inspected.
Tire Rotation
WARNINGRotate 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 (TEMPORAR Y 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: 
Incorrect tire pressure 
Improper wheel alignment 
Out-of-balance wheel 
Severe braking
After rotation, inflate all tire pressures to
specification (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 differential)
Do not use the following: 
Tires not of the designated size 
Tires of different sizes or types at
the same time 
Tires not sufficiently inflated
If these instructions are not 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.

There is a malfunction in the battery management system. 
There is a malfunction in the brake switch.
Electric Vacuum
Pump Warning
Light The light turns on if the electric vacuum pump system has a problem. Have your vehicle
inspected at an Authorized Mazda Dealer.
ABS Warning Light If the ABS warning light stays on while you're driving, the ABS control unit has detected a
system malfunction. If this occurs, your brakes will function normally as if the vehicle had
no ABS.
Should this happen, consult an Authorized Mazda Dealer as soon as possible.
NOTE 
When the engine is jump-started to charge the battery, uneven rpm occurs and the ABS
warning light may illuminate. If this occurs, it is the result of the weak battery and does
not indicate an ABS malfunction.
Recharge the battery.

The brake assist system does not operate while the ABS warning light is illuminated.
Check Engine Light If this light illuminates while driving, the vehicle may have a problem. It is important to
note the driving conditions when the light illuminated and consult an Authorized Mazda
Dealer.
The check engine light may illuminate in the following cases: 
The engine's electrical system has a problem. 
The emission control system has a problem. 
The fuel tank level being very low or approaching empty. 
The fuel-filler cap is missing or not tightened securely.
If the check engine light remains on, or it flashes continuously , do not drive at high speeds
and consult an Authorized Mazda Dealer as soon as possible.
