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. 44) 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 the tire label located on the driver’s 
side door opening) on all four 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.

NOTE: 

Drastic changes in temperature or altitude can affect the air pressure in the tires, 

and may cause the TPMS warning light to turn on. Verify the tire pressures when driving 
through extreme temperature or altitude changes.

TIRE PRESSURE MONITORING SYSTEM

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.
