 When the warning light illuminates, and the 
warning beep sound is heard (about 3 seconds), 
tire pressure is too low in one or more tires.

WARNING

  If the tire pressure monitoring system 
warning light illuminates or fl ashes, 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 fl ashes, 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 
fl at, 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 
dangerous, 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.   

 Inspect the tires and adjust to the specifi ed 
infl ation pressure (page  6-42 ).

   NOTE

y

Perform tire pressure adjustment when the tires 

are cold. Tire pressure will vary according to 
the tire temperature, therefore let the vehicle 
stand for 1 hour or only drive it 1.6 km (1 mile) 
or less before adjusting the tire pressures. 
When pressure is adjusted on hot tires to the 
cold infl ation pressure, the TPMS warning 
light/beep may turn on after the tires cool and 
pressure drops below specifi cation.
  Also, an illuminated TPMS warning light, 
resulting from the tire air pressure dropping 
due to cold ambient temperature will remain 
illuminated even if the ambient temperature 
rises. In this case, it will also be necessary 
to adjust the tire air pressures. If the TPMS 
warning light illuminates due to a drop in tire 
air pressure, make sure to check and adjust the 
tire air pressures. 

y

  Tires lose air naturally over time and the TPMS 

cannot tell if the tires are getting too soft over 
time or you have a fl at. However, when you 
fi nd 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 can 
inspect any low tire for cuts and any metal 
objects sticking through tread or sidewall. Put 
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 reinfl ating 
the tire as leaks are dangerous — take it to an 
Authorized  Mazda  Dealer.

Warning 

Light

*

 The light turns on if the windshield and the radar 
sensor are dirty or there is a malfunction in the 
system.

 Verify the reason why the warning light is 
illuminated on the center display (page 7-24 ).
  If the reason why the warning light is 
illuminated is due to a dirty windshield, clean 
the windshield.
  If the warning light is illuminated because of a 
dirty radar sensor, clean the front emblem.
  For any other reasons, have the vehicle 
inspected at an Authorized Mazda Dealer.
