### Installation Procedure

Important: Manually push the glass panel rearwards on both sides in order to check that the sunroof is at the maximum open position. This procedure sets both the slide and/or the guide, and the cables.

1. Install the actuator motor.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Install the screws to the actuator motor.

Tighten
Tighten the actuator motor screw to 5 N·m (44 lb in).

3. Connect the electrical connector to the actuator motor.
4. Align the front edge of the sunroof actuator motor cover to the headliner and push cover into place.
