The power sunroof (CF5 option) has the following features:

1. A manually operated sunshade. A recess is provided in the sunshade to be used to push the shade open or pull it shut.
2. An express module at the front of the sunroof module, allows the window panel to stop in the closed, vent and fully open positions.
3. The Position Encoding System (PES) module contains the limit switches for the window panel operation. Its gearing drives the window into the desired position. The window panel must be in the CLOSED position when this unit is replaced.
4. The sunroof actuator attaches to the PES module and contains the driveshaft that drives the gearing in the PES. This driveshaft will turn infinitely in both directions.
