Air Suspension Height Control Switch
Notice: Do not operate the vehicle over uneven ground such as ramps, speed bumps, curbs, etc. with the air springs deflated. Doing this may lead to air bag separation from the piston, preventing the suspension air springs from re-inflating.
The air suspension height control switch is used to adjust the vehicle height to aid in coupling or uncoupling from a trailer. See Fig.. Setting the switch to DOWN deflates the air springs to lower the rear of the vehicle. In the UP position, the air springs inflate to raise the rear of the vehicle to normal ride height.

Notice: Never exhaust air from the suspension while driving. When the air is exhausted, the suspension will not absorb road shocks, and components may be damaged.
A red LED in the switch is illuminated when the suspension is deflated.
