Handling the Unexpected
If the Low Tire Pressure/Tire Pressure Monitoring
System (TPMS) Indicato r Comes On or Blinks
■Reasons for the indicato r to come on or blink
The pressure of one or more tires is significantly low, or TPMS with Tire

Have the tire inspected by a dealer as soon as possible. If the compact
spare tire causes the indicator to blink, change the tire to a full-size tire.
The indicator goes off after driving for a few miles (kilometers).

Indicator Comes On or Blinks
NOTICE
Driving on an extremely unde rinflated tire can cause
it to overheat. An overheated tire can fail. Always
inflate your tires to the prescribed level.
TPMS with Tire Fill Assist provides visual and audible
assistance during tire pre ssure adjustment. With the
