TIRE PRESSURE MONITORING SYSTEM (TPMS)

For your safety, the CX-3 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. 40-41) 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 the tires 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 jamb area) 

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.

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.
