2018 MAZDA MODEL CX-9 warning

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.

▼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.

3. After about 15 minutes, drive thevehicle at a speed of at least 25 km/h
(16 mph) for 10 minutes and the tire
pressure sensor ID s ignal code will be
registered automatically.
NOTE
If the vehicle is driven within about 15
minutes of changing tires, the tire pressure
monitoring system warning light will flash
because the sensor ID signal code would
not have been registered. If this happens,
park the vehicle fo r about 15 minutes,
after which the sensor ID signal code will
register upon driving the vehicle for 10
minutes.
Replacing tires and wheels
CAUTION
 When replacing/repairing the tires or
wheels or both, have the work done by
an Authorized Mazda Dealer, or the tire
pressure sensors may be damaged.
 The wheels equipped on your Mazda are
specially designed for installation of the
tire pressure sensors. Do not use
non-genuine wheels, otherwise it may
not be possible to install the tire pressure
sensors.
Be sure to have the tire pressure sensors
installed whenever tires or wheels are
replaced.
When having a tire or wheel or both
replaced, the following types of tire
pressure sensor installations are possible.
•The tire pressure sensor is removed
from the old wheel and installed to the
new one.
•The same tire pressu re sensor is used
with the same wheel. Only the tire is
replaced.
•A new tire pressure sen sor is installed to
a new wheel.
NOTE
•The tire pressure sensor ID signal code
must be registered when a new tire
pressure sensor is purchased. For
purchase of a tire pressure sensor and
registration of the tire pressure sensor
ID signal code, consult an Authorized
Mazda Dealer.
•When reinstalling a previously removed
tire pressure sensor to a wheel, replace
the grommet (seal between valve body/
sensor and wheel) for the tire pressure
sensor.

the parking sensor switch is
pressed at a vehicle speed of 10
km/h (6 mph) or less. The system may have a malfunctio
n. Have the vehicle inspected at an Author-
ized Mazda Dealer as soon as possible.
The beep sound is not heard. The system may have a malfunctio
n. Have the vehicle inspected at an Author-
ized Mazda Dealer as soon as possible.
The intermittent sound of the
buzzer is heard five times. Remove any foreign material from the sensor area. If the system
does not re-
cover, have the vehicle inspect ed at an Authorized Mazda Dealer .
A certain obstruction detection
indicator is continuously dis-
played. Refer to Obstruction Detection Indication on page 4-176.
