2009 Ford F450 Super Duty Crew Cab Owner's Manual - Page 113

Driver Controls Powerfold mirror positions, from left to right: Position 1, Position 2, Position 3 The powerfold mirrors may be folded forward/rearward manually to any of the three positions shown and electrically to positions 1 and 2 only. If a mirror is folded manually forward to position 3, you must manually fold it back to position 1 or 2 in order for the powerfold function to continue functioning. Note: Although it is possible to electrically fold the mirror from position 3 to 2, it was not designed for this functionality and may not always work under all conditions. Note: Ten or more switch activations within one minute, or repeated fold/unfolding of the mirrors while holding the switch rearward during the full travel may cause the system to disable the fold/unfold function to protect the motors from overheating. Should this occur, wait approximately 31⁄2 minutes for the system to reset and function to return to normal. Note: The powerfold mirrors are designed to operate while the vehicle is stationary or traveling at moderate speeds. If you attempt to powerfold the mirrors at high speeds, they may not fully fold forward/rearward slow down and powerfold or manually fold the mirrors in order to complete the fold operation. Note: If the power fold/telescope mirror glass appears loose or vibrates when driving, it is possible that the mirrors have been manually folded or telescoped. To minimize the vibration, ensure that the mirrors are electronically folded and telescoped in/out with the switches on the door trim panel. If the power fold mirrors are out of sync, electronically powerfold the mirrors to re-sync the motors. This will cause a loud click and the mirrors will jerk during re-synchronization. This is normal. 113 2009 F-250/350/450/550 (f23) Owners Guide, 3rd Printing USA (fus)
