Failure turn of glass lid
• Failure turn of glass lid while driving rough road.
Glass lid has auto-reverse function. When applied above specified force to the glass lid, the lid turns back
and stops. When operating the glass lid (open or close) while driving the rough road, the lid judges vibration
as a force and may causes failure turns. When the failure turn is occurred, the initialize operation is required
with following procedure.
1. INITIALIZE OPERATION (SEDAN MODEL)

tialization of position detecting function)
4) Keep pressing the tilt up switch within 5 seconds from releasing the switch, glass lid tilts down " slides
open " slides close operation automatically. (Time gap of more than 5 seconds will result in cancellation of
position detecting function.)
5) Initialize operation is completed.
2. INITIALIZE OPERATION (WAGON MODEL)
1) Apply the force to glass lid in the direction of glass lid open while glass lid (rear) is closing, and then re-
verse the lid five times in a row.
However, in the following situation, the initialize operation is canceled.
• When the lid is fully closed once during auto-reverse operation five times in a row.
• When the interval of auto-reverse operation is more than 30 seconds once.
