Safety Information
Be sure to park the trailer on solid, level ground. Ensure all jack landing locations are cleared of debris and
obstructions and also free of depressions. People and pets should be clear of trailer while operating the leveling
system. Ensure the battery of the trailer is fully charged or that the trailer is plugged into shore power prior to
attempting to operate the system. Ground Control 3.0 requires a minimum of 12.75V DC from the battery for proper
operation.
Lippert Components Inc. recommends that a trained professional be employed to change the tires on the trailer.
Ensure that the trailer is properly supported with jack stands or other adequate devices under the frame of the
trailer prior to commencing any service or repair procedure. Any attempts to change the tires or perform other
service while trailer is supported solely by the Ground Control 3.0 jacks could
result in death, serious injury, trailer or property damage.

Operation - Auto Leveling Control Touch Panel
Unhitching Instructions
NOTE: Prior to unhitching from the tow vehicle, ensure the trailer is parked on a level surface and chock the tires of
the trailer.
1. Extend the inner legs of both front jacks (landing gear) to within 4-5" of the ground by pulling on the quick-
release pins.
2. To turn on the touch panel, press both "UP" and "DOWN" arrows (Fig. 1B and Fig. 1C) at the same time. The
green indicator LED (Fig. 1A) will turn on.
NOTE: The touch panel will remain on as long as the user is pressing buttons. It will time out after approximately 7
minutes without use.
3. Press the "UP" arrow (Fig. 1B) to extend the front jacks and lift the front of the trailer to take the weight of the
trailer off of the hitch.
4. Uncouple the trailer connection on the tow vehicle.
5. Pull the tow vehicle away and park at a safe distance.
Auto Level
1. After unhitching from the tow vehicle and parking the vehicle at a safe distance away from the trailer.
Press both "UP" and "DOWN" arrows (Fig. 1B and Fig. 1C) at the same time if the green indicator LED is not on.
Press “AUTO LEVEL” (Fig. 1D).
NOTE: Once the automatic leveling cycle has been started, it is important that there is no movement in the
trailer until the leveling process is complete. Failure to remain still during the leveling cycle could
have an effect on the performance of the leveling system.
Auto Level Sequence
1. When Auto Level Sequence begins, the front of the trailer will seek a position near a level state.
2. Rear jacks will be grounded.
3. A side-to-side leveling sequence will occur.
NOTE: At this point on the 6 point system, the 2 middle jacks will be grounded to stabilize the trailer.
These 2 jacks do not level the trailer.
4. Each jack will perform a final grounding touch.
NOTE: If the AUTO LEVEL sequence does not perform as described above, locate the OneControl Touch
Panel inside the trailer or use the OneControl App to place the system in manual mode. Test that
the jacks operate correctly by pushing their corresponding buttons on the OneControl Touch Panel
or app; e.g., "FRONT" button operates only the front jacks, etc. (See "Operation - OneControl Touch
Panel" or "Operation - OneControl App" in this manual).
Hitch Recognition
1. To turn on the touch panel, press both "UP" and "DOWN" arrows (Fig. 1B and Fig. 1C) at the same time. The
green indicator LED (Fig. 1A) will turn on.
2. Press "HITCH HEIGHT" (Fig. 1E). The rear jacks will retract.
3. The front of the trailer will raise to the height where the auto level sequence was started.
NOTE: If the front of the trailer was below level when the Auto Level process was initiated, the hitch recognition
feature will retract the rear jacks but will not retract the front jacks to lower the trailer to the initial hitch
height. This feature helps prevent injury and/or damage to anything underneath the trailer.
4. Connect tow vehicle and make sure trailer and hitch are connected and locked.
5. Press "RETRACT ALL." (Fig. 1F). System will immediately retract all jacks.
6. Use the quick release pins on the landing gear to manually return the inner jack leg to the fully retracted
position.

Special Jack Error Codes on OneControl Touch Panel or OneControl App
To clear the error codes listed below:
1. Correct or otherwise repair the issue (see the table below).
NOTE: In order to clear the special jack error code the jacks need to be "homed." In order to "home" jacks,
each jack must be able to retract a minimum of 6".
2. Extend all jacks to reach the 6" of minimum retract needed.
A. Press "FRONT" (Fig. 3B or Fig. 6B) to extend the front jacks (if required).
B. Press "REAR" (Fig. 3D or Fig. 6D) to extend the rear jacks (if required).
C. Press "LEFT" and "RIGHT" (Fig. 3A and Fig. 3C or Fig. 6A and Fig. 6C ) simultaneously to extend the
middle jacks (if equipped and required).
3. Press "ENTER" to AUTO RETRACT. The jacks will retract until they reach the hard current limit.
4. The jacks are now “homed” and the special jack error code will be cleared.
NOTE: If the jacks do not retract, an error should display on the touch panel screen. This is typically caused
by wiring interruption.

Zero Point Calibration
The “Zero Point” is the programmed point that the trailer will return to each time the Auto Level feature
is used. The “Zero Point” must be programmed prior to using the Auto Level feature to ensure the proper
operation of the system. The "Zero Point" feature is only available on the OneControl Touch Panel and
OneControl App with this system. (Figs. 17-22 depict OneControl Touch Panel.)
NOTE: Prior to starting this procedure, double check all connections on the controller, jacks, and touch
panel.
NOTE: When calibrating Zero Point, the user has full manual control over the jacks. See “Basic Jack
Operation - Manual Mode” to adjust to the desired level position. Press the enter button to set.
To Set the Zero Point
NOTE: The following procedure works from Standard Mode only. (See "Standard Mode and Menu" to reach
standard mode.)
1. Press the “CONNECTED” icon (Fig. 17A) at the top of the leveling screen quickly 6 times. Wait a few
seconds until the gear icon with "OPTIONS" appears (Fig.18A ).
2. Press the gear icon with "OPTIONS" (Fig. 18A).
3. The screen will show "SET UP: Zero Mode Press Enter" (Fig. 19).
4. Press the “Enter button” (Fig. 19A).
5. The touch panel will present options for further leveling of the trailer if needed. The screen will also
state "ZERO POINT CALIBRATION - Press Enter to Set" (Fig. 20).
6. Press "ENTER" (FIG. 20A).
7. Screen will show "Zero Point Stability Check ... Please Wait" (Fig. 21), followed by "Zero Point Set"
(Fig. 22).

Preventive Maintenance
1. For optimum performance, the system requires full battery current and voltage. The battery must be
maintained at full capacity.
2. Check the terminals and other connections at the battery, the controller, and the jacks for corrosion,
and loose or damaged connections.
3. Remove dirt and road debris from jacks as needed.
4. If jacks are down for extended periods, it is recommended to spray exposed leveling jack rods with a
silicone lubricant every three months for protection. If the trailer is located in a salty environment, it is
recommended to spray the rods every four to six weeks.
