Ground Control 3.0 Service Manual
Auto Level
1. After unhitching from tow vehicle and parking the vehicle at a safe distance away from the unit, press
the “ON/OFF” button (Fig. 1K) and then press “AUTO LEVEL” (Fig. 1F).
NOTE: Once the automatic leveling cycle has been started, it is important that there is no movement in the
coach until the unit has completed the leveling process. Failure to remain still during the leveling
cycle could have an effect on the performance of the leveling system.
NOTE: In order for hitch recognition feature to function, the auto level sequence MUST be started with the
front of the unit above level.
Auto Level Sequence
1. When Auto Level Sequence begins, the front of the unit will lower slightly to a point below level. The
coach will then stop and raise up to the point where it is level from front to rear.
2. Rear leveling jacks are grounded.
3. A side to side leveling sequence occurs.
NOTE: At this point on the 6-point system, the two middle jacks are grounded to stabilize the unit. These
two jacks do not level the unit.
4. Each jack will perform a final grounding touch.
5. LCD will read “AUTO LEVEL SUCCESS” (Fig. 3).
6. LCD will then read “READY Jacks: Down” (Fig. 4A), and the green LED at the center of the four jack
buttons will be illuminated (Fig. 4B).

NOTE: If the AUTO LEVEL sequence does not perform as described, place the system in the manual mode
and test that the jacks operate correctly by pushing their coordinating buttons on the touch pad;
i.e. FRONT button operates only the front jacks.
Hitch Recognition
1. Turn on touch pad.
2. Press the left and right buttons simultaneously (Fig. 1H/I).
3. All leveling jacks will retract first, then the landing gear will extend to raise the unit to the height where
the auto level sequence was started.
NOTE: If the auto level sequence was started with the front of the unit in a below-level condition, the
Hitch Recognition will not function and the LCD will display “Feature Disabled.” In order for hitch
recognition feature to function, the auto level sequence MUST be started with the front of the unit
above level.
