MAZDA MODEL CX-3 2021 Owners Manual

Wa r n i n g
When the warning light illuminates, an d the warning beep sound is heard when tire pressure is too low in one or
more tires.
WA R N I N G
If the tire pressure monitoring system warning light illuminates or flashes, or the tire pressure warning beep sound
is heard, decrease vehicle speed immediately and avoid sudden maneuvering and braking:
If the tire pressure monitoring system warning light illuminates or flashes, or the tire pressure warning beep sound
is heard, it is dangerous to drive the vehicle at high speeds, or perform sudden maneuvering or braking. Vehicle
drivability could worsen an d 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 da ngerous, 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 situation that could lead to tire failure and a
dangerous accident.

Action to be taken
Inspect the tires and adjust to the specified inflation pressure (page 6-36).
CAUTION
When replacing/repairing the tires or wheels or both, have the work done by an Authorized Mazda Dealer, or the
tire pressure sens ors may be damaged.
NOTE
Perform tire pressure adjustment when the tires are cold . Tire pressure will vary according to the tire temper‐
ature, therefore let the vehicle stand for 1 hour or on ly drive it 1.6 km (1 mile) or less before adjusting the
tire pressures. When pressure is adjusted on hot tires to the cold inflation pressure, the TPMS warning light/
beep may turn on after the tires cool and pressure drops below specification.
Also, an illuminated TPMS warning light, resulting from th e tire air pressure dropping due to cold ambient
temperature, may turn off if the ambient temperature rises. In this case, it will also be necessary to adjust the
tire air pressures. If the TPMS warnin g light illuminates due to a drop in tire air pressure, make sure to check
and adjust the tire air pressures.
After adjusting the tire air pressures, it may require some time for the TPMS warning light to turn off. If the
TPMS warning light remains illuminated, drive the vehicle at a speed of at least 25 km/h (16 mph) for 10
minutes, and then verify that it turns off.
Tires lose air naturally over time and the TPMS cannot tell if the tires are getting too soft over time or you
have a flat. However, when you find one low tire in a set of four-that is an indication of trouble; you should
have someone drive the vehicle slowly forward so you ca n inspect any low tire for cuts and any metal objects
sticking through tread or sidewall. Pu t a few drops of water in the valve stem to see if it bubbles indicating a
bad valve. Leaks need to be addressed by more than simply refilling the trouble tire as leaks are dangerous
― take it to an Authorized Mazda Dealer which has all the equipmen t to fix tires, TPMS systems and order
the best replacement tire for your vehicle.
If the warning light illuminates again even after the tire pressures are adjusted, there may be a tire puncture.
