Note: At least two IKTs are required to perform this procedure yourself. Illuminated entry The interior lamps and parking lamps illuminate when the remote entry system is used to unlock the door(s).

The dome lamp control (if equipped) must not be set to the off position for the illuminated entry system to operate. The lights will not turn off if: • they have been turned on with the dimmer control, or • any door is open. The battery saver will shut off the interior lamps 30 minutes after the ignition has been turned to the off position, 10 minutes after if the dome lamp is off, and 30 minutes after if the dome lamp switch is left on. 145 2012 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
