Air Suspension Switch
WARNING: This page is about a different car, the 2010 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Shut off the electrical power to the air suspension system prior to hoisting or jacking an air suspension equipped vehicle. Failure to do so may result in unexpected inflation or deflation of the air springs, which may result in shifting of the vehicle during these operations. Failure to follow this instruction may result in serious personal injury.
In the ON position, the air suspension switch provides a signal to the Vehicle Dynamics Module (VDM) which, in turn, activates the system to maintain vehicle height. In the OFF position, the air suspension switch interrupts this signal to the VDM which, in turn, deactivates the system.
