If the reset mode has been entered successfully, the horn will sound
once, the TPMS indicator
will flash and the message center (if
equipped) will display TRAIN LEFT FRONT TIRE. If this does not
occur, please try again starting at step 2.
If after repeated attempts to enter the reset mode, the horn does not
sound, the TPMS indicator
does not flash and the message center (if

from your authorized dealer.

• Left rear (Driver’s side rear tire)
