When Driving
Tire Pressure Monitoring System
CAUTION
 


 Each tire, including the spare (if provided), should be checked monthly when cold and
infl ated to the infl ation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire infl ation pressure label. (If your vehicle has tires of a diff erent size than the
size indicated on the vehicle placard or tire infl ation pressure label, you should determine
the proper tire infl ation 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 signifi cantly under-infl ated. Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and infl ate them to the proper
pressure. Driving on a signifi cantly under-infl ated tire causes the tire to overheat and can
lead to tire failure. Under-infl ation also reduces fuel effi ciency and tire tread life, and may
aff ect 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-infl ation has not
reached the level to trigger illumination of the TPMS low tire pressure telltale.
  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 fl ash 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.
 


 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 defl ation or blow out.

When Driving
Tire Pressure Monitoring System
NOTE
Because this system detects slight changes in tire conditions, the timing of the warning may
be faster or slower in the following cases:
 


 The size, manufacturer, or the type of tires is different from the specifi cation.



 The size, manufacturer, or the type of a tire is different from the others, or the level of tire
wear is excessively different between them.
 


 A run-fl at tire, studless tire, snow tire, or tire chains are used.



 An emergency tire is used (The tire pressure monitoring system warning light may fl ash
and then continue illuminating).
 


 A tire is repaired using the emergency fl at tire repair kit.



 The tire pressure is excessively higher than the specifi ed pressure, or the tire pressure is
suddenly lowered for some reason such as a tire burst during driving.
 


 The vehicle speed is lower than about 15 km/h (9.3 mph) (including when the vehicle is
stopped), or the drive period is shorter than 5 minutes.
 


 The vehicle is driven on an extremely rough road or a slippery, icy road.



 Hard steering and rapid acceleration/deceleration are repeated such as during aggressive
driving on a winding road.
 


 Load on the vehicle is applied to a tire such as by loading heavy luggage to one side of
the vehicle.
 


 System initialization has not been implemented with the specifi ed tire pressure.

Maintenance and Care
Owner Maintenance
Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire infl 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 9-9 )
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 Infl 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 9-9 .

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
(including the spare) when the tires are
cold. Maintain recommended pressures for
the best ride, handling, and minimum tire
wear.
Refer to the specifi cation charts (page
9-9 ).
(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 4-153 .

Maintenance and Care
Owner Maintenance
*Some models.
CAUTION
 


 Do not use your temporary spare tire
rim with a snow tire or a conventional
tire. Neither will properly fi t and could
damage both tire and rim.
 


 The temporary spare tire has a tread life
of less than 5,000 km (3,000 miles). The
tread life may be shorter depending on
driving conditions.
 


 The temporary spare tire is for limited
use, however, if the tread wear solid-
band indicator appears, replace the tire
with the same type of temporary spare
(page 6-45 ).

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. You should replace the
spare tire when you replace the other road
tires due to the aging of the spare tire. 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:




 Tire fi t



 Wheel and bearing life



 Ground clearance

the new one is the same as the original
factory wheel in diameter, rim width,
and offset (inset/outset).
 


 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 fl at spots.

blocks of suffi cient size if possible to hold
the tire in place.

Removing a Flat Tire
WARNING
When jacking-up a vehicle, always shift
the selector lever to P, apply the parking
brake, and place wheel blocks in the
position diagonally opposed to the jack:
Changing a fl at tire without using
wheel blocks is dangerous because the
vehicle may move and fall off the jack
even with the select lever is in P, which
could result in an accident.

1. Loosen the lug nuts by turning them
counterclockwise one turn each, but do
not remove any lug nuts until the tire
has been raised off the ground.



2. Place the jack on the ground.
3. Turn the jack screw in the direction
shown in the fi gure and adjust the jack
head so that it is close to the jack-up
position.
