TIRE PRESSURE MONITORING SYSTEM (TPMS)

For your safety, the Mazda3 is equipped with TPMS that detects low 
tire pressure in one or more tires. If the tire pressure starts getting 
low in one or more tires, the system alerts the driver by turning on a 
light in the instrument cluster (pp. 33-36) and sounding an alarm.

What to do?

 Don’t ignore the TPMS warning light. Stop and check your tire 

pressure (when the tires are cold) and inflate them to the proper pressure. 

Properly inflated tires are safer, last longer, and increase fuel economy.

In the following cases, the TPMS must be “initialized” so the system can 
operate normally.

• 

The tire pressure is adjusted (up or down) in one or more tires.

• 

A tire rotation is performed.

• 

Any tire or wheel is replaced.

• 

The vehicle’s battery is disconnected, replaced or completely dead. 

Initialization Process (TPMS Warning Light   is Illuminated)

1

  Park the vehicle in a safe place and firmly apply the parking brake.

2

  Let the tires cool, then adjust the tire pressure to  

the specified pressure (see tire label located on  

the driver’s side door opening) on all four (4) tires.

3

  Switch the ignition ON, but leave the vehicle parked.

4

  Push and hold the TPMS “Set Switch”  

(left side of dash) until the TPMS warning light    

in the instrument cluster flashes twice and a beep  

sound is heard once.

Tires

CAUTION:

 If the TPMS “Set Switch” is pushed without adjusting the tire 

pressure, the system cannot detect the normal tire pressure. The TPMS 

warning light may not turn on, even if the tire pressure is low, or it may turn on 

if the tire pressure is normal.

NOTE: 

Drastic changes in temperature or altitude can affect the pressure in the 

tires, causing the TPMS warning light to turn on. Verify the tire pressures when 

driving through extreme temperature or altitude changes.
