When Driving
Tire Pressure Monitoring System
Tire Pressure Monitoring System *
The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all\
four tires. If
the air pressure of one or more tires is too low, the system warns the driver by indicating the
tire pressure monitoring system warning light in the instrument cluster \
and operating a beep
sound. The system monitors the tire pressures indirectly using the data sent fr\
om the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the specifi ed
tire pressure (value on the tire pressure label). Follow the procedure\
and perform the
initialization.
Refer to Tire Pressure Monitoring System Initialization on page 4-106 .
The warning light fl ashes when the system has a malfunction.
Refer to Warning Lights on page 4-21 .

If the tire pressure monitoring system has a malfunction, the tire press\
ure warning
light fl ashes for about 1 minute when the ignition is switched ON and then conti\
nues
illuminating. Have your vehicle checked by an Authorized Mazda Dealer as soon as
possible.
WARNING
If the tire pressure monitoring system warning light illuminates or fl ashes, or the tire
pressure warning beep sound is heard, decrease vehicle speed immediately and avoid
sudden maneuvering and braking: If the tire pressure monitoring system warning light illuminates or fl ashes, or the tire
pressure warning beep sound is heard, it is dangerous to drive the vehicle at high
speeds, or perform sudden maneuvering or braking. Vehicle drivability could worsen
and result in an accident.
To determine if you have a slow leak or a fl at, pull over to a safe position where you can
check the visual condition of the tire and determine if you have enough air to proceed
to a place where air may be added and the system monitored again by an Authorized
Mazda Dealer or a tire repair station.
Do not ignore the TPMS Warning Light: Ignoring the TPMS warning light is dangerous, even if you know why it is illuminated.
Have the problem taken care of as soon as possible before it develops into a more
serious situation that could lead to tire failure and a dangerous accident.

CAUTION
If the key warning indicator light illuminates or the push button start indicator light

using the emergency operation for starting the engine, and have the vehicle inspected
at an Authorized Mazda Dealer as soon as possible.

The warning light fl ashes when the system has a malfunction. Have your vehicle inspected
at an Authorized Mazda Dealer.
The LDWS does not operate when the warning light fl ashes.
CAUTION
¾ If any of the following cases occurs, the system may have a malfunction. Have the vehicle
inspected at an Authorized Mazda Dealer.
¾ The light fl ashes while the vehicle is being driven.
¾ The light does not illuminate when the ignition is switched ON.
¾ Always use tires for all wheels that are of the specifi ed size, and the same manufacture,
brand, and tread pattern. In addition, do not use tires with signifi cantly diff erent wear
patterns on the same vehicle. If such improper tires are used, the LDWS may not operate
normally.
¾ When an emergency spare tire is used, the system may not operate normally.

When the warning light illuminates, and the
warning beep sound is heard (about 3 seconds),
tire pressure is too low in one or more tires.
WARNING
If the tire pressure monitoring system
warning light illuminates or fl ashes, or the
tire pressure warning beep sound is heard,
decrease vehicle speed immediately and
avoid sudden maneuvering and braking: If the tire pressure monitoring system
warning light illuminates or fl ashes, or the
tire pressure warning beep sound is heard,
it is dangerous to drive the vehicle at high
speeds, or perform sudden maneuvering
or braking. Vehicle drivability could worsen
and result in an accident.
To determine if you have a slow leak or a
fl at, pull over to a safe position where you
can check the visual condition of the tire
and determine if you have enough air to
proceed to a place where air may be added
and the system monitored again by an
Authorized Mazda Dealer or a tire repair
station.
Do not ignore the TPMS Warning Light: Ignoring the TPMS warning light is
dangerous, even if you know why it is
illuminated. Have the problem taken care of
as soon as possible before it develops into
a more serious situation that could lead to
tire failure and a dangerous accident. Inspect the tires and adjust to the specifi
ed
infl ation pressure (page 6-42 ).
NOTE
yPerform tire pressure adjustment when the tires
are cold. Tire pressure will vary according to
the tire temperature, therefore let the vehicle
stand for 1 hour or only drive it 1.6 km (1 mile)
or less before adjusting the tire pressures.
When pressure is adjusted on hot tires to the
cold infl ation pressure, the TPMS warning
light/beep may turn on after the tires cool and
pressure drops below specifi cation.
Also, an illuminated TPMS warning light,
resulting from the tire air pressure dropping
due to cold ambient temperature will remain
illuminated even if the ambient temperature
rises. In this case, it will also be necessary
to adjust the tire air pressures. If the TPMS
warning light illuminates due to a drop in tire
air pressure, make sure to check and adjust the
tire air pressures.
y Tires lose air naturally over time and the TPMS cannot tell if the tires are getting too soft over
time or you have a fl at. However, when you
fi nd one low tire in a set of four-that is an
indication of trouble; you should have someone
drive the vehicle slowly forward so you can
inspect any low tire for cuts and any metal
objects sticking through tread or sidewall. Put
a few drops of water in the valve stem to see if
it bubbles indicating a bad valve. Leaks need
to be addressed by more than simply reinfl ating
the tire as leaks are dangerous — take it to an
Authorized Mazda Dealer.

Warning Light
*
The light turns on if the windshield and the radar
sensor are dirty or there is a malfunction in the
system. Verify the reason why the warning light is
illuminated on the center display (page 7-24 ).
If the reason why the warning light is
illuminated is due to a dirty windshield, clean
the windshield.
If the warning light is illuminated because of a
dirty radar sensor, clean the front emblem.
For any other reasons, have the vehicle
inspected at an Authorized Mazda Dealer.
