To Open

Opening the sunroof can be done from any position between fully closed and partially open. To open the sunroof glass, press and hold the sunroof switch to the first rearward position. This will apply the sunroof switch low reference circuit to the sunroof switch open vent signal circuit (12-volt reference) input, pulling the reference voltage to 0 volts. The constant low (0 volts) input to the sunroof module indicates an open request. Once the open has been initiated, the sunroof module will drive the motor in the open direction, slightly lowering the rear edge of the sunroof glass, then sliding open with the sunshade, allowing the wind deflector to raise upward. The sunroof glass will continue to open until the sunroof motion is terminated by either:

• Motor stall is sensed because the sunroof has reached its limit of travel or due to an obstruction.
• Releasing of the sunroof switch. The sunroof may be left in any position between fully open and fully closed.
• The operation time-out expires, 15 seconds after the initiation of the express open feature had been commanded.
