The slight lift experienced during the stabilizing procedure
normally is not sufficient to cause a level issue for the motor
home. However, a feature of the single step leveling system
is the manual leveling buttons will function anytime the
ignition is in the ON or ACC. position and the park brake is
set. If desired, the operator can use the UP ARROWS
(extend jacks) that correspond to any lit yellow level indicator
light to "bump" the vehicle up slightly to turn that yellow
indicator light off.
During the automatic
leveling sequence, after the system has extended the
appropriate jacks to level the vehicle and has turned
the yellow level indicator lights off, the system will
then stabilize the vehicle.
The switch will turn on when the jack extends to the ground
and lifts the vehicle slightly. Jacks that have lifted the vehicle
for leveling should have pressure switches that are on.
The sequence starts with the right rear jack. If the pressure
switch is not on, the system will extend the jack as necessary.
If the switch is on (or when it comes on) the system will check
the left rear jack pressure switch, extending the jack if necessary
If the left rear switch is on (or when it comes on), the system
will recheck the right rear (extending if necessary) then recheck
the left rear (extending if necessary). After checking and
rechecking both rear jacks, the system then checks the front
jacks. The system checks both front jacks at the same time.
If either pressure switch is not on, the system will turn the
pump on and open the valves for both front jacks. When
both front pressure switches are on, the system turns the
pump and front valves off.
