2021 MAZDA MODEL 3 HATCHBACK warning light

CAUTION
Adjust the tire pressures while the
tires are cool. Because the air
pressure in the tires fluctuates
depending on the temperature,
before adjusting the tire pressures,
let the vehicle sit for an hour or drive
it only within a 1.6 km (1 mile)
distance. If the tire pressures are
adjusted while the tires are warm,
the tire pressures may decrease
below the specified air pressure after
cooling down which could turn on
the warning light. In addition,
because the air pressure in the tires
decreases when the ambient
temperature is low, if the ambient
temperature increases, an
illuminated TPMS warning light may
turn o ff. Under any circumstances,
always adjust the tire pressures while
the tires are cool.
 After adjusting the tire pressures, the
TPMS warning light turns o ff. If the
TPMS warning light does not turn off,
drive the vehicle at a speed of about
25 km (16 mph) or faster for 3
minutes or longer and make sure the
warning light turns off.
If the TPMS warning light remains on
even after adjusting the tire pressures,
one of the tires may have a puncture.
