SLIDING SUNROOF OPERATION
• The glass panel opens/closes using tilting and sliding operations.
• When the ignition switch is at the ON position, the sunroof operates by use of the sunroof switch.
• If the ignition switch is turned to the LOCK or ACC position while the sunroof is operating, it will stop.
• One-touch operation of the SLIDE open or the TILT up switch provides auto-operation.
• If any switch is operated during auto-operation, the sunroof stops.
• If any malfunction is detected during sunroof operation, the fail-safe function operates to ensure safety.

Specification
If the switch is continuously on for longer than the set
time (60 s), operation is stopped.
If the period of accumulated energization due to
continuous opening/closing is longer than the set time
(120 s), operation is stopped.
(If set time is reached while closing, sunroof returns to
fully open position.)
If the motor power supply is on continuously due to stuck
breaker points in a relay on one side or similar
malfunction, the other relay is turned on, cutting off
energization to the motor.
(Even if the ignition switch is turned to the LOCK or ACC
position, the coil is energized.)
If the pulse variation of Hall IC 1 is not longer than the set
time (400 ms), operation is stopped (pinching detected).
If pinching is detected while the glass panel is sliding,
sliding operation is stopped.
Set load: 343 N {35 kgf, 77 lbf} or more
If an abnormal Hall IC pulse is detected, the system
enters safe mode.
• Abnormality while operating: Operation stopped
• Abnormal condition when the switch is operated:
Glass panel operates for 400 ms in the direction of
sunroof switch operation and stops.
