MANUAL OPERATION
The UP and DOWN arrow button on the right side of the touch panel allow manual control of the air bags. The ignition must be
in the “ON” or “ACC” position and the park brake must be set for the UP and DOWN arrows to function. There are four sets of
buttons, front, left side, right side and rear. The UP arrow buttons will open the raise valves to allow are into the air bags,
raising the vehicle. The DOWN arrow buttons will open the lower valves to exhaust air from the air bags, lowering the vehicle.
These buttons will always operate two corners of the vehicle at a time for Bi-Axis leveling, both front air bags, both rear air
bags, the left front and left rear air bags or the right front and right rear air bags.
It is not recommended to push more than
one UP or DOWN arrow at a time.
You can lower the vehicle first like the automatic leveling sequence does or you can level the vehicle by first lowering the side
and/or end of the vehicle opposite of any lit yellow level light. I. E. The left side level light is on. Push and hold the DOWN
arrow button for the right side. If lowering the right side does not turn the left side level light out, push and hold the left side UP
arrow to raise the left side of the vehicle. It is recommended to level the vehicle side to side first, if needed, then front to rear.
The UP and DOWN arrow buttons will not function if the LEVELING SYSTEM ACTIVE light is flashing.
NOTE: There is no EXCESS SLOPE or SLEEP mode in manual leveling. If the “AIR” button is pushed after manually
leveling the vehicle, even if all yellow level lights are out, the auto level sequence will start from the beginning
including first dumping all air from the air bags.
“DUMP” AND “RAISE” BUTTONS
The DUMP button will exhaust air from all of the suspension air bags to lower the whole vehicle. The RAISE button will add air
to all of the suspension air bags to RAISE vehicle. The ignition has to be in the “ON” or “ACC” position for the DUMP and
RAISE buttons to function but the park brake does NOT have to be set. The system has a wire that connects to the
transmission speed switch. When below the speed setting of the switch, the DUMP and RAISE buttons will latch in and lower
or raise the vehicle to the minimum (lower) or maximum (raise) height allowed by the suspension and air bags. If the system is
not connected to the speed switch, the buttons become momentary and will stop lowering or raising the vehicle when
released. If the park brake is off, the suspension will return to the normal ride height.
IMPORTANT: The DUMP and RAISE buttons are a feature that allow you to raise or lower the vehicle while moving at
a very slow speed to clear an obstacle such as a curb or branch. The vehicle should not travel any significant
distance without being at the proper ride height.
