You don't need level surface, just follow Lippert procedure:
Level Zero Point Calibration
Before the auto leveling features are available, the Level Zero Point must be set. This is the point to which
the system will return when an auto leveling cycle is initiated. To set the Zero Point (controller module must
be fully secured in production-intent location), first run a manual leveling sequence to get the vehicle to
the desired level point. Then activate the Level Zero Point configuration mode. This mode is enabled by
performing the following sequence.
1. Turn the Touch Pad OFF.
2. Turn the Touch Pad ON and perform the following:
A. Press the Front button 5 times.
B. Press the Rear button 5 times.
NOTE: At this point all LED outputs will blink. This indicates the system is in the IDLE mode ready to set Zero
Point.
3. Press the Retract All button 3 times.
NOTE: All LEDs will go out except the WAIT light. The WAIT light will blink continuously for approximately
20 seconds while the Level Zero Point is being programmed into the controller.
NOTE: For Diesel Units with Automatic Airbag Suspensions ONLY: - Press the Retract All button 3 more
times to program the auto dump/auto fill feature for the airbags.
4. The WAIT light will then go off and the LCI logo in the middle will illuminate, indicating a successful
programming of the Zero Point configuration.
