    Take the appropriate action and verify that the warning light turns off.

 (Illuminate)
  Tire  Pressure  Monitoring 
System Warning Light 
*   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 
 6-43 ).
   NOTE
      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.   
 
  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.
