Questions and Answers

Is there a delay time between loading and unloading before it starts leveling?
View Staff Answer 

The system has a 25 second delay before the compressor and solenoid will function. Once the magnet is set in position and no movement is detected by the EHS, it will take 25 seconds for the compressor, or the deflate solenoid, to turn on and level the vehicle by inflating, or deflating, the air springs in the suspension.
