Air Suspension Dump 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.
If equipped, the air suspension dump switch can be used to adjust the vehicle height to aid in coupling or uncoupling from a trailer. See Fig..
Toggling the switch up deflates the air springs to lower the rear of the vehicle. The upper icon of the switch will illuminate red when active.
Toggling the switch up again will 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.
