MAZDA CX90 2024 Owners Manual

Tire Pressure MonitoringSystem (TPMS)
The TPMS monitors the air pressure of
each tire and informs the driver of a
decrease in the tire air pressure when it
becomes lower than the specified air
pressure.
For the TPMS, the air pressure data
sent from the tire pressure sensors
installed on each wheel via radio signal
is received by the receiver unit in the
vehicle to monitor the tire pressures.

Warning and Cautions forUsing the Tire Pressure Monitoring System
(TPMS)
WARNING
Do not drive the vehicle at high
speeds if the TPMS warning light
is
turned on or flashing.
Driving the vehicle at high speeds
while the TPMS warning light is turned
on or flashing is dangerous because
the brake performance and the
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 brake and reduce
the vehicle speed.
Do not ignore the TPMS warning light
when it is turned on or flashing.
Continuing to driv e 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.

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 has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low tire
pressure 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-inflated 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 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.

How to Use the Tire
Pressure Monitoring System (TPMS)
Check the tire pressure
The current tire pressure can be
checked on the center display.
Refer to the Vehicle Status Monitor
section in the Mazda Connect
Owner's Manual.
Low tire pressure warning
When a tire pressure of the specified
air pressure or lower is detected, the
TPMS warning light
turns on and a
warning indication is displayed in the
instrument cluster.
1. Message is displayed.
Action
1. Adjust the tire pressure to the appropriate pressure.
Refer to the Tires on page 10-71.
CAUTION
If the tire pressure is adjusted when
the tire is warm, the tire pressure
may lower below the specified
pressure after cooling and the
warning light may turn on. Adjust
the air pressure of the tires when
they are cold.
2. Make sure that the TPMS warning
light
is turned off.
3. If the TPMS warning light does
not turn off, drive the vehicle for 3
minutes or longer at a speed of 25
km/h (16 mph) or faster.
4. Make sure that the TPMS warning
light
is turned off.
If the TPMS warning light remains on
even after adjusting the tire pressure,
there is a possibility that the tire is flat.
CAUTION
When inspecting/adjusting the tire
pressures, do not apply excessive force
to the air valve of the tire pressure
sensor. Otherwise, the tire pressure
sensor could be damaged.
When changing tires and wheels
When changing the tires or wheels
(such as installing winter tires), it will
be necessary to register the ID signal
code of the tire pressure sensor to the
TPMS.
Have an Authorized Mazda Dealer do
the registration or register the ID signal
codes of the tire pressure sensors using
the following procedure.
NOTE
The tire pressure sensors on each
wheel have a unique ID signal code.
For the TPMS to operate correctly, the
ID signal codes of the tire pressure
sensors need to be registered to the
system.
1. Wait more than 19 minutes after changing a tire or wheel.
2. After more than 19 minutes have passed, drive the vehicle at a speed
of 25 km/h (16 mph) or faster for 3
minutes or longer. While driving,
the ID signal codes of the tire
pressure sensors are automatically
registered.

NOTE
If you drive the vehicle within 19
minutes of changing a tire or wheel,
the TPMS warning light
will flash
because the ID signal codes for the tire
pressure sensors were not registered.
In this case, stop the vehicle and
register the ID signal codes of the tire
pressure sensors following the
procedure.
When replacing tires and wheels
CAUTION
 When replacing the tires and wheels,
consult an Authorized Mazda Dealer
Otherwise, the tire pressure sensors
could be damaged when replacing
them.
 Do not install non-genuine wheels. If
wheels other than genuine ones are
installed, it may not be possible to
install the tire pressure sensors.
When replacing a tire or wheel, always
install the tire pressure sensor. The
following combinations of tires,
wheels, or tires and wheels are
possible.
The tire pressure sensor from the old
wheel is removed and it is installed
to the new wheel.
Only a tire is replaced without
replacing the tire pressure sensor and
wheel.
A new tire pressure sensor is installed
to a new wheel.
NOTE
When installing a new tire pressure
sensor, the ID signal code for the tire
pressure sensor needs to be registered.
For details on purchasing a tire
pressure sensor and registering the ID
signal of the tire pressure sensor,
consult an Authorized Mazda Dealer.

Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use ONLY UNLEADED
FUEL, which will reduce exhaust emissions and keep spark plug fouling to a
minimum.

To achieve maximum engine performance, use the specified fuel.
Fuel
Octane Rating*1 (Anti-knock index)
Premium unleaded fuel 91 [(R+M)/2 method] or above (96 RON or above)
Regular unleaded fuel with an octane rati ng from 87 to 90 (91 to 95 RON) can be
used, but this will reduce performance slightly, such as reduced engine output, and
engine knocking.
Fuel with a rating lower than 87 octane (91 RON) will negatively affect the emission
control system performance and could al so cause engine knocking and serious
engine damage.
*1 U.S. federal law requires that octane ratings be posted on gas station pumps.
CAUTION
 USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic converter and oxygen sensors and will lead
to deterioration of the emission control system and or failures.
 This vehicle can only use oxygenated fuels containing no more than 10 % ethanol
by volume. Damage to the vehicle may occur when ethanol exceeds this
recommendation, or if the gasoline cont ains any methanol. Stop using gasohol of
any kind if your vehicle engine is performing poorly.
 Never add fuel system additives other than a Mazda genuine product, otherwise
the emission control system could be damaged. Consult an Authorized Mazda
Dealer for details.
Gasoline blended with oxygenates such as alcohol or ether compounds are generally
referred to as oxygenated fuels. The comm on gasoline blend that can be used with
your vehicle is ethanol blended at no more than 10 %. Gasoline containing alcohol,
such as ethanol or methanol, may be marketed under the name "Gasohol".

Vehicle damage and drivability problems resulting from the use of the following may
not be covered by the warranty.
Gasohol containing more than 10 % ethanol.Gasoline or gasohol containing methanol.Leaded fuel or leaded gasohol.

enables the vehicle to comply with
existing exhaust emissions
requirements.
NOTE
Under U.S. federal law, any
modification to the
original-equipment emission control
system before the first sale and
registration of a vehicle is subject to
penalties. In some states, such modification made on a used vehicle
is also subject to penalties.
While the engine is off, the sound of
a valve opening and closing can be
heard at the rear of the vehicle,
however this does not indicate an
abnormality. The vehicle has a
self-checking device and it operates
while the engine is off.

Warnings and Cautionsfor Using the Emission Control System
WARNING
Never park over or near anything
flammable.
Parking over or near anything
flammable, such as dry grass, is
dangerous. Even with the engine
turned off, the exhaust system remains
very hot after normal use and could
ignite anything flammable. A resulting
fire could cause serious injury or death.
CAUTION
Ignoring the following precautions
could cause lead to accumulate on the
catalyst inside the converter or cause
the converter to get very hot. Either
condition will dama
ge the converter
and cause poor performance.
 USE ONLY UNLEADED FUEL.
 Do not drive your Mazda with any
sign of engine malfunction.
 Do not coast if the vehicle power is
switched OFF.
 Do not descend steep grades in gear
if the vehicle power is switched OFF.
 Do not operate the engine at high
idle for more than 2 minutes.
 Do not tamper with the emission
control system. All inspections and
adjustments must be made by a
qualified technician.
 Do not push-start or pull-start this
vehicle.
Warnings and Cautions
for Engine Exhaust
(Carbon monoxide)
WARNING
Do not drive your vehicle if you smell
exhaust gas inside the vehicle:
Engine exhaust gas is dangerous. This
gas contains carbon monoxide (CO),
which is colorless, odorless, and
poisonous. When inhaled, it can cause
loss of consciousness and death. If you
smell exhaust gas inside the vehicle,
keep all windows fully open and
contact an Authorized Mazda Dealer
immediately.
Do not run the engine when inside an
