MAZDA MODEL CX-5 2021 Owners Manual As an added safety feature, your vehicle has 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

As an added safety feature, your vehicle has 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 th e 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 reduce s 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 sequen ce 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 fo r a little while before indicating a problem. As
a result it will not instantaneously regi ster 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 pressure sensor batteries
are exhausted.
When using a wheel with no tire
pressure sensor installed.
When using tires with steel wire
reinforcement in
the sidewalls.
When using tire chains.

MAZDA MODEL CX-5 2021 Owners Manual Selective Catalytic Reduction (SCR) System*
The SCR system is designed to reduce nitrogen oxide (NOx) in the exhaust gas and purify
the exhaust gas by injecting it with Diesel Exhaust Fluid (DEF).
WAR

Selective Catalytic Reduction (SCR) System*
The SCR system is designed to reduce nitrogen oxide (NOx) in the exhaust gas and purify
the exhaust gas by injecting it with Diesel Exhaust Fluid (DEF).
WARNING
Be careful not to allow the DEF to run out. If the DEF completely runs out, the SCR system will
not operate normally.
When the remaining DEF is low, a message is displayed on the multi-information display, and
the SCR warning light turns on/flashes.
Refer to Selective Catalytic Reduction (SCR) System Indications on page 4-261.
In this case, consult an Authorized Mazda Dealer. If DEF needs to be replenished, add DEF
following the specified procedure.
Refer to Diesel Exhaust Fluid (DEF) Replenishment on page 6-30.
NOTE
DEF needs to be replenished periodically according to the scheduled maintenance
information.
Normally, the vehicle can be driven about 12,000 km (7,500 miles) before the DEF needs
to be replenished. However, it may need to be replenished earlier depending on the
driving and environmental conditions (such as putting a high load on the engine while
driving or driving the vehicle at high altitudes).
The sound of the SCR system operating may be heard from the area under the vehicle,
however, this does not indicate a problem.
▼ Selective Catalytic Reduction
(SCR) System Indications
As the remaining amount of Diesel Exhaust Fluid (DEF) lowers, the SCR system notifies
the driver using the following indications.
The vehicle speed may be restricted for a while even if the warning light turns off after
replenishing the DEF. To cancel the vehicle speed restriction immediately, switch the
ignition OFF after the warning light turns off and then switch the ignition ON again.

NOTE
If the windshield fogs up easily, set the
mode selector dial to the
position.
If cooler air is desired at face level, set
the mode selector dial at the
position
and adjust the temperature control dial
to maintain maximum comfort.
The air to the floor is warmer than air
to the face (except when the temperature
control dial is set at the extreme hot or
cold position).
▼ Cooling
1. Set the mode selector dial to the
position.
2. Set the temperature control dial to the
