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 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 illuminates 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 

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 

specified inflation 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 inflation pressure, the TPMS 

warning light/beep may turn on after 

the tires cool and pressure drops below 

specification.

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 flat. However, when you find 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 reinflating the tire as leaks are 

dangerous — take it to an Authorized 

Mazda Dealer.
