A tilt and slide apparatus and method for a sunroof of a vehicle includes a movable panel, a drive shoe configured to slide in a forward/rearward direction relative to the front of the vehicle, a lift guide connected to an end of the movable panel, and a check assembly including a locking component. The check assembly couples the drive shoe and the lift guide when the drive shoe is slid in the forward direction to the lift guide. A guide ramp formed on the drive shoe is an angled indented surface configured to align a portion of the locking component in order to couple the drive shoe and the lift guide. The guide ramp is formed as a tapered groove that has a width in a vehicle width direction that is continuously broadened from a front end of the groove toward a rear end of the groove.
