9. Make sure the harness does not put any pressure on the camera, forcing it out of position while docked in its
bracket. The gap between the camera base and the top of the bracket should be parallel. If it is not, shift the
harness to relieve the pressure off the spring clips that hold the camera in place.
NOTE: Do not adjust the spring clips in the camera bracket to set the gap.
10. Connect the rearview mirror connector.
11. Reinstall the rearview mirror.
12. Install the review mirror cover.
13. Do the multipurpose camera unit aiming procedure, according to the service information. LKAS requires both static
and dynamic aiming with the i-HDS.
