▼Tire Pressure Monitoring System
(TPMS) Warning Indication/
Warning Light (Flashing)
If there is a problem with the TPMS or
the voltage of a tire pressure sensor
decreases, the TPMS warning light
flashes and a message is displayed on
the multi-information display. Have
your vehicle inspected by an
Authorized Mazda Dealer.
WARNING
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 illumi
nation/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.

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.
