- Tilt up/ down & slide open/ close signals from moonroof switch enables moonroof motor to move arbitrarily.
- Moonroof motor assembly receives a vehicle speed signal from combination meter and controls the moonroof motor torque of tilt-down at the time of high speed operation.

Retained power function cancel conditions
- Front door close (door switch off)ƒ¸open (door switch on).
- When ignition switch is ON again.
- When timer time passes. (45 seconds)
Anti-pinch function
The cpu of moonroof motor assembly monitors the moonroof motor operation and the moonroof position (fully-closed or other) by the signals from moonroof motor.
When moonroof motor detects an interruption during the following slide close and tilt down operation, moonroof switch controls the motor for open and the moonroof will operate until full up position (when tilt down operates) or 100 mm (3.94 In) or more in an open direction (when slide close operates):
- Close operation and tilt down when ignition switch is in the “on” position
