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 illumin ates 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 and 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.
