Pressure Monitoring System; If there is a problem with the Tire- Page 362

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-in

fl

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 de

fl

ation or blow out.

If there is a problem with the Tire

Pressure Monitoring System

(TPMS)

If the TPMS warning light 

fl

ashes, there

may be a problem with the system.

Consult an Authorized Mazda Dealer

to have the system inspected.

Refer to Tire Pressure Monitoring

System (TPMS) Warning Indication/

Warning Light (Flashing) on page

7-33.

In the following cases, the system

cannot recognize the tire pressures

correctly and the TPMS warning light

may 

fl

ash.



There is equipment or a device

nearby emitting radio signals the

same as a tire pressure sensor.



A metallic object such as a

non-genuine electronic device is

installed near the center of the

dashboard (obstructs the radio

signals from the tire pressure sensors

to the receiver).



A device such as one of the following

is used in the cabin.



Electronic devices such as a

computer.



Converter devices such as a

DC

-

AC converter.



There is a large accumulation of

snow or ice around the vehicle tires.



The battery in a tire pressure sensor

is dead.



A wheel not equipped with a tire

pressure sensor is used.



Tires employing steel in the sidewall

of the tire are installed.



Tire chains are used.
