or retained power is operating.

• Tilt up/ down & slide open/ close signals from sunroof switch enable sunroof motor to move arbitrarily.

• Sunroof motor assembly receives a vehicle speed signal from combination meter and controls the sunroof

motor torque of tilt down at the time of high speed operation.

AUTO OPERATION

out holding the sunroof switch in the slide open/tilt down or slide close/tilt up position.
