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 (p. 35-38) and sounding an alarm.

What to do?

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

tire pressure (when 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 jam area) 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.

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 may cause the TPMS warning 

light to turn on.
