System Failure to act in accordance with the following may result in serious personal injury or death. The use of the Lippert Electronic Leveling System to support the coach for any reason other than which it is intended is prohibited by Lippert’s limited warranty. The Lippert leveling system is designed as a “leveling” system only and should not be used to provide service for any reason under the coach such as changing tires or servicing the leveling system. Lippert Components, Inc.
Features • Automatic extension of jacks from full retract position (with automatic ground detection). • Automatic leveling of jacks. • Manual leveling of jacks • Automatic retraction of jacks (with automatic full retract detection). • Air bag suspension features (configurable on/off). • Emergency retract/User alarm mode (jacks not retracted and park brake disengaged). • Automatic jack error detection and error mode. • Configuration mode for Air features. • Configurations mode for Leveling Zero Point.
Air and Auxiliary Features (When Applicable) System has the option to control external Air and Auxiliary features. When enabled, the feature works according to the following logic: • Air bag pressure automatically lowered when starting the auto or manual sequence to maximize lift of jacks. • An Auxiliary mode activated when starting an auto retract sequence to fill air bags. • Auxiliary is active when jacks are all retracted and park brake is disengaged to fill airbags.

Pressure Switch Operation Selecting a Site When the coach is parked on an excessive slope, the leveling requirements may exceed the jack lift stroke capability. If the coach is parked on an excessive slope, the coach should be moved to a more level surface before the leveling system is deployed.
Automatic Leveling Procedure Note: Refer to Fig. 3 for questions regarding location and functions of the Lippert Components, Inc. Electronic Leveling System. Note: Coach must be running and parking brake must be engaged for LCI Electronic Leveling System to operate. 1. Push ON/OFF button on Control Panel. The system is now operational and the electronic level lights will become active. 2. Check to see that the Control Pad ENGAGE PARK BRAKE light is not flashing. 3.
Jack Retract Procedures 1. Energize the system by pushing ON/OFF button on control panel. The ON/OFF light will be lit. 2. Push the RETRACT ALL JACKS button. All the jacks will start to retract and return to the full retract position. When all jacks return to full retract position the JACKS DOWN light will go out. Note: If you wish to stop the jacks from retracting, turn the system off and back on again by pushing the ON/OFF button twice. You can then re-level the coach by following steps 1-5 again. 3.
Manual Override - Jacks In the event that the jacks will not extend or retract, the valves can be manually overridden by using a 5/32” Allen wrench (Pre-2006 model year, see update below) to turn the manual override clockwise on the valve. (See Fig. 7A.) The leveling jacks can then be extended or retracted. Remember to turn the manual override completely counterclockwise (See Fig. 7B) until it will no longer turn, to close the valve after the jacks have been completely extended or retracted. Fig. 7A Fig.
“Jacks Down" Alarm The Lippert Electronic Leveling System is designed to sound an alarm and illuminate the control panel in the event of two (2) possible scenarios: A. A “RETRACT” hose leaks. B. The pressure holding the jacks in the retracted position falls to approximately 1500 psi to sound the alarm. If the alarm sounds and the control panel illuminates and flash while driving the vehicle: 1. Immediately find an area to safely pull the vehicle off of the roadway. 2. Set the PARKING BRAKE. 3.
Preventative Maintenance Procedures 1. Change fluid in RESERVOIR ONLY when contaminated. A. Check fluid only when jacks are fully retracted. B. Always fill the reservoir with the jacks in the fully retracted position. Filling reservoir when jacks are extended will cause reservoir to overflow into its compartment when jacks are retracted. C. When checking fluid level, fluid should be within ¼” of fill spout lip. 2. Check the fluid level every month. 3.
Troubleshooting Chart Problem System will not turn on and on/off indicator light does not illuminate Control pad turns on but turns off when leg button is pushed Probable Cause Coach ignition not in RUN position Parking brake not set Controls have been on for more than four minutes and have timed out Corrective Action Low voltage on battery Start coach to charge battery Control pad turns on, coach will not auto-level, jacks down light Low fluid level is on, jacks are retracted Jacks will not extend to
