In event of a power failure, the sunroof window panel may be opened or closed manually. The headliner will need to be lowered in the rear to access the motor/actuator which has an allen head on the bottom side of the drive gear. Use of an allen wrench will allow manual cranking of the motor and drive gear. After each manual operation of the sunroof, the motor must be reprogrammed by performing the Initialization/Teach procedure. Refer to Sunroof Motor/Actuator Initialization/Teach Process.
