OFF, apply the parking brake
manually.
The sound of the parking brake being
applied or released can be heard,

problem.
If the EPB is not used for long
periods, an automatic inspection of
the system is performed while the

sound can be heard, however, this
does not indicate a problem.
When applying the parking brake
and switching OFF the ignition, an
operation sound can be heard,
however, this does not indicate a

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-inflation 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 flash 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 deflation or blow out.▼ If there is a problem with the Tire
Pressure Monitoring System
(TPMS)
If the TPMS warning light flashes, 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
7-27.
In the following cases, the system
cannot recognize the tire pressures
correctly and the TPMS warning light
may
flash.
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.
▼When a tire pressure decreases
If the TPMS warning light turns on, a
tire pressure may be low. Inspect the
tire pressures and adjust them to the
correct inflation pressure.

WARNING
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

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 illumi nation/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.
