C2: Auto Off Timers; C3: Self-Timer - Nikon D5100 Reference Manual

c2: Auto off Timers

This option determines how long the monitor remains on if no operations are
performed during menu display and playback (Playback/menus), while
photographs are displayed in the monitor after shooting (Image review), and during
live view (Live view), and how long the exposure meters, viewfinder, and information
display remain on when no operations are performed (Auto meter-off ). Choose
shorter auto-off delays to reduce the drain on the battery.
