Go into your Configuration.h file and turn on:
#define AUTO_BED_LEVELING_FEATURE
But you will also need to define things like X_PROBE_OFFSET_FROM_EXTRUDER, Y_PROBE_OFFSET_FROM_EXTRUDER, Z_PROBE_OFFSET_FROM_EXTRUDER. And... You will have to configure the servo information also. And... That assumes you want the default Auto Bed Leveling. There are several flavors (and required configuration of each flavor) to choose from.
