checking MAZDA MX5 MIATA 2023 Owners Manual

▼Emission Control System
This vehicle is equipped with an emission control system (the catalytic converter is part of
this system) that enables the vehicle to comply with existing exhaust emissions
requirements.
WA R N I N G
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 damage the converter
and cause poor performance.
 USE ONLY UNLEADED FUEL.
 Do not drive your Mazda with any sign of engine malfunction.
 Do not coast with the ignition switched
off.
 Do not descend steep grades in gear with the ignition 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 tow-start this vehicle.
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.

Blind Spot Monitoring (BSM)*
The BSM is designed to assist the driver in checking the area to the rear of the vehicle on
both sides during lane changes by alerting the driver to the presence of vehicles approaching
from the rear in an adjacent lane.
The BSM detects vehicles approaching from the rear while traveling in the forward
direction at a speed of 10 km/h (6.3 mph) or faster and turns on the BSM warning lights
equipped on the door mirrors depending on the conditions. If the turn signal lever is
operated to signal a lane change in the direction in which the BSM warning light is
illuminated, the system warns the driver of a vehicle in the detection area by flashing the
BSM warning light and activating a beep sound.
The detection area on this system covers the driving lanes on both sides of the vehicle and
from the rear part of the doors to about 50 m (164 ft) behind the vehicle.
Detection areas Your vehicle

Tire Pressure Monitoring System
The Tire Pressure Monitoring System (TPMS) monitors the pressure for each tire.
If tire pressure is too 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 Contact Authorized Mazda Dealer and Have Vehicle Inspected on page 7-36.
Refer to Taking Action on page 7-40.
Refer to Tire Inflation Pressure Warning Beep on page 7-50.

The tire pressure sensors installed on each wheel send tire pressure 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 condition of all four tires
regularly.
