When initialization of the tire pressure warning system has failed
Initialization may take longer to complete if the vehicle is driven on an
unpaved road. When performing initialization, drive on a paved road if
possible. Depending on the driving environment and condition of the tires,
initialization will be completed in approximately 10 to 30 minutes. If initial-
ization is not complete after driving approximately 10 to 30 minutes, con-
tinue driving for a while.
If the inflation pressure of each tire is not displayed after driving for
approximately 1 hour, perform the following procedure.
●
Park the vehicle in a safe place for approximately 20 minutes. Then
drive straight (with occasional left and right turns) at approximately
25 mph (40 km/h) or more for approximately 10 to 30 minutes.
However, in the following situations, the tire inflation pressure will not be
recorded and the system will not operate properly. Perform initialization
again.
●
When operating the tire pressure warning reset switch, the tire pressure
warning light does not blink 3 times.
●
After performing initialization, the tire pressure warning light blinks for 1
minute then stays on while driving about 20 minutes.
If the inflation pressure of each tire is still not displayed, have the vehicle
inspected by your Toyota dealer.
