OVERVIEW

Door Mechanisms
The laminated windshield is bonded and sealed to the body aperture using PU (polyurethane) adhesive. Bonded to the inner surface of the windshield is the mounting boss for the interior mirror. Dependent on vehicle specification, the windshield may contain 2 heating elements between the windshield laminations.
The toughened rear screen is also bonded and sealed to the body aperture using PU (polyurethane) adhesive. A single heating element is printed on the inner surface of the rear screen.
Operation of the window lift system is controlled by the CJB (central junction box) in conjunction with the driver door module and the front passenger door module. The door modules are mounted on the regulators of their respective front windows. Door modules are also mounted on both rear window regulators, and communicate with the front door modules over the LIN (local interconnect network) bus.
The window lift system features one shot up and down operation, plus an anti-trap feature for all door windows.
If the battery is disconnected, the window lift system will require calibrating on battery re-connection. To calibrate the system the following routine must be carried out.
With the ignition on:
- Fully close the door glass and release the switch.
- Re-apply the switch to close the door glass and hold for approximately 2 seconds.
- Fully open the door glass and release the switch.
- Re-apply the switch to open the door glass and hold for approximately 2 seconds.
- Repeat for all remaining windows.

Roof Opening Panel
The roof opening panel is, in fact, a roller blind for the fixed glass roof.
The roller blind is electrically operated through a 2 way rocker switch located in the overhead console. An electric motor, attached to the front of the frame of the glass roof, drives the roller blind. The roller blind is operated by 2 cables, which are driven by the motor.
Operation of the roller blind is controlled by the roller blind control unit, which is integral with the motor. The control unit receives inputs from the BCM (body control module) and the switch to control the roller blind operation accordingly.
