B: INSPECTION

• 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, need to perform the initialize op-
eration with following procedure.

1. INITIALIZE OPERATION (SEDAN MODEL)

1) Tilt up the glass lid.
2) Release the switch once, and press the tilt up switch again for 15 seconds.
3) When the glass lid is raised a little and returned to tilt up position, release the switch for the moment. (Ini-
tialization of position detecting function)
4) Keep pressing the tilt up switch within 5 seconds from releasing the switch. The glass lid will tilt down 

o

slides open 

o slides close automatically. (When 5 seconds pass, the position detecting function is can-

celled.)
5) Initialize operation is completed.

2. INITIALIZE OPERATION (WAGON MODEL)

1) Apply force to the glass lid in the opening direction while the glass lid (rear) is closing, and make it reverse
five times in a row.
However, in the following situation, the initialize operation is canceled.
• When the lid is fully closed once during one of the auto-reverse operations five times in a row.
• When the interval between the auto-reverse operations was 30 seconds or more even once.
2) When the operation of glass lid shifts to inching operation

*

, fully close the lid by switch operation.

3) Initialize operation is completed.
* Inching operation: A condition where the glass lid only operates for only at the moment when the switch is
pressed, even when the switch is held down.
