In Open Procedure





In Close Procedure






SEQUENCE OF HYDRAULIC SYSTEM

There are 22 states in hydraulic system. Hydraulic system is controlled using combination of these 22 states and, at the same time, open and close operations of retractable hard top system are performed interlocking with other retractable hard top system components. (For interlock with other components, refer to "RETRACTABLE HARD TOP SYSTEM : System Description" System Description)
Parts state (CONSULT display) according to sequential hydraulic system operations is as shown in the following table.
