Thank you for purchasing the revolutionary e-Level™ system by AccuAir.
This system manages the height of up to 4 Air Springs and offers never
before seen accuracy in all applications by constantly learning your vehicle's
characteristics. Through the use of advanced height monitoring techniques,
this system automatically corrects for changes in load, whether driving or
parked, minimizing user input and maximizing accuracy throughout your
driving experience. To enhance the entire system's performance and reli-
ability, the AccuAir e-Level™ also manages your Air Compressor(s) to keep
onboard air at an ideal pressure for your application.
To maximize functionality, the AccuAir e-Level™ allows you to select from
three distinct vehicle heights through a Rocker Switch:
1.) Ride Height (The height that you will typically drive your vehicle at).
2.) Low/Cruise (Typically set at 10% of your total suspension travel).
3.) High/Extra Clearance (Typically set at 90% of your total suspension
travel to increase mobility and clear driving obstacles).
