Driver Controls
The ride heights are selected via the rotary control switch mounted on the center console. Rotating the switch upwards or downwards selects a different ride height. The center of the rotary switch contains the HOLD switch. The HOLD switch prevents the air suspension ECU from automatically changing from the currently selected ride height, and prevents the user selecting a new ride height. The air suspension ECU is able to provide 4 different ride heights. See RIDE HEIGHT POSITIONS .
Next to the rotary control switch are mounted a series of 4 LEDs. See Fig 1. An illuminated LED indicates which ride height is active. If a new ride height is selected using the rotary control switch, the CURRENT height LED remains illuminated and the REQUESTED height LED flashes until the vehicle achieves the new ride height. If a new ride height is selected using the rotary control switch and the CURRENT height LED flashes briefly, this indicates that the ride height selection is invalid and will not be performed. When the operating parameters are correct for the new ride height, the height change request must be repeated.
