TPMS MAZDA MODEL CX-9 2018 Owners Manual (in English)

Tire Pressure Monitoring System*
The Tire Pressure Monitoring System (TPMS) monitors the pressure for each tire.
If tire pressure is to o low in one or more tires, the system will inform the driver via the
warning light in the instrument cluster and by the warning beep sound.
Refer to Warning Indication/Warning Lights on page 4-32.
Refer to Tire Inflation Pressu re Warning Beep on page 7-50.

The tire pressure sensors installed on each wheel send tire pre ssure data by radio signal to
the receiver unit in the vehicle.
Tire pressure sensors
NOTE
When the ambient temperature is low due to seasonal changes, tire temperatures are also
lower. When the tire temperature decreases, the air pressure decreases as well. The TPMS
warning light may illumina te more frequently. Visually inspect the tires daily before driving,
and check tire pressures monthly with a tire pressure gauge. When checking tire pressures,
use of a digital tire pressure gauge is recommended.

TPMS does not alleviate your need to check the pressure and con dition of all four tires
regularly.

CX-9_8GC3-EA-17G_Edition1 2017-5-29 10:13:38

CAUTION
Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the
size indicated on the vehicle placard or tire inflation pressure label, you should determine
the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle ha s been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pre ssure telltale when one or more of your tires is
significantly
under-inflated. Accordingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate them to the proper
pressure. Driving on a significantly under-in flated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect 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 ti re 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 wi ll 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 th at 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.

▼System Error Activation
When the warning light flashes, there may
be a system malfunction. Consult an
Authorized Mazda Dealer.
A system error activation may occur in the
following cases:
•When there is equipment or a device
near the vehicle using the same radio
frequency as that of the tire pressure
sensors.
•When a metallic device such as a
non-genuine navigation system is
equipped near the center of the
dashboard, which may block radio
signals from the tire pressure sensor to
the receiver unit.
•When using the following devices in the
vehicle that may cause radio
interference with the receiver unit.
•A digital device such as a personal
computer.
•A current converter device such as a
DC-AC converter.
•When excess snow or ice adheres to the
vehicle, especially around the wheels.
•When the tire pressu
re sensor batteries
are exhausted.
•When using a wheel with no tire
pressure sensor installed.
•When using tires with steel wire
reinforcement in the side walls.
•When using tire chains.
▼ Tires and Wheels
CAUTION
When inspecting or adjusting the tire air
pressures, do not apply excessive force to
the stem part of the wheel unit. The stem
part could be damaged.
Changing tires and wheels
The following procedure allows the TPMS
to recognize a tire pressure sensor's unique
ID signal code whenever tires or wheels
are changed, such as changing to and from
winter tires.
NOTE
Each tire pressure sensor has a unique ID
signal code. The signal code must be
registered with the TPMS before it can
work. The easiest way to
do it is to have
an Authorized Mazda Dealer change your
tire and complete ID signal code
registration.
When having tires changed at an
Authorized Mazda Dealer
When an Authorized Mazda Dealer
changes your vehicle's tires, they will
complete the tire pressure sensor ID signal
code registration.

When changing tires yourself
If you or someone else changes tires, you
or someone else can also undertake the
steps for the TPMS to complete the ID
signal code registration.
1. After tires have been changed, switch
the ignition ON, then back to ACC or
OFF.
2. Wait for about 15 minutes.

SignalWarning
(Flashing)
Tire Pressure Moni-
toring System
Wa r n i n g L i g h t
*
If the tire pressure monitoring s ystem has a malfunction, the tire pressure warning light
flashes. Have your vehicle check ed by an Authorized Mazda Deale r as soon as possible.
WA R N I N G
If the tire pressure monitoring system warning light illuminates or flashes, or the tire pres‐
sure warning beep sound is heard, decrease vehicle speed immediately and avoid sudden
maneuvering and braking:
If the tire pressure monitoring system warnin g light illuminates or flashes, or the tire pres‐
sure warning beep sound is heard, it is dang erous to drive the vehicle at high speeds, or
perform sudden maneuver ing or braking. Vehicle drivabilit y could worsen and result in an
accident.
To determine if you have a slow leak or a flat, 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 situa‐
tion that could lead to tire failure and a dangerous accident.
