is displayed in yellow.
WA R N I N G
Do not drive the vehicle at high speeds if
the TPMS warning light turns on or flashes:
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 brakes to
lower the vehicle's speed.
Do not ignore the TPMS warning light
when it is turned on or flashing:
Continuing to drive the vehicle while
ignoring the illumination/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.
NOTE
While the TPMS is learning the tire
positions, such as immediately after a tire
position has been changed, the tire
pressure at the tire position prior to it
being changed is displayed until the
system completes the learning. For this
reason, the tire pressures displayed for the
tire positions may be different from the
actual tire pressures at the tire positions.
Action to be taken
Adjust the tire pressu res to the appropriate
pressures.
Refer to Tire Inflation Pressure on page
6-30.

Mazda3_8HE9-EA-18K_Edition1 2018-10-17 19:05:10

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 off. Under
any circumstances, always adjust the tire
pressures while the tires are cool.
 After adjusting the tire pressures, the
TPMS warning light turns off. 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.
Refer to Changing a Flat Tire on page 7-7.
