AccuAir e-Level Manual

Introduction

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 reliability, 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).

Service Disable

For all under vehicle maintenance, you must first disable the air system by removing the main system fuse located near the battery.

General Understanding

For simplicity of use and understanding we refer to the four wheels of a vehicle by number. Instead of using "Left Front", or "Right Front" etc. Refer to the following diagram for labeling:

General Operation

Setup Programming

Automatic System Calibration (Suggested)

Do NOT use this procedure for KELDERMAN Systems because suspension damage will occur. Use the procedure below.
Before the system will operate, it must be calibrated to learn the vehicle characteristics. This process should be repeated if any air suspension components get changed or replaced in the future.
NOTE: Your system was shipped with the Tank Pressure Mode set at 150 PSI. If you have High Pressure Compressor(s) you can change the Tank Pressure Mode to 175 PSI or 200 PSI, before calibrating below.

The system will automatically Raise/Lower the vehicle in the next procedure. Remove all obstructions and keep clear of vehicle before proceeding.
The vehicle needs to be on level ground with the wheels pointed straight ahead. Leave vehicle running to power the Compressor(s) during this procedure.

Automatic Calibration:
Turn the Ignition OFF. Then hold Program "" Button while turning the Ignition ON.

The system will then begin adjusting the vehicle throughout its total travel. This process requires no user interaction and should take no more than 15 minutes depending on the size of your Compressor(s) and Tank(s).
Both the "" and "" Arrow will flash slowly during calibration. The "" Arrow will be on when calibration is complete, indicating that the system is at Ride Height (currently saved at 50% of your total travel).
When calibration is complete the positions will be saved as follows:

• Position #1 = 10% of total suspension travel.
• Position #2 = 50% of total suspension travel.
• Position #3 = 90% of total suspension travel.

To re-save these heights to your preference.

Manual Range System Calibration (Alternative to Automatic Calibration)

Maximum Height will be determined by you; instead of your mechanical suspension limits! This procedure should only be used on suspensions that are likely to over extend.
Your system must be calibrated to learn your vehicle's characteristics before the automatic leveling features can be used. This process should be repeated if any system components are changed or replaced in the future.

The system will automatically Raise/Lower the vehicle in the next procedure. Remove all obstructions and keep clear of vehicle before proceeding.
The vehicle needs to be on level ground with the wheels pointed straight ahead. Leave vehicle running to power the Compressor(s) during this procedure.
With the Ignition ON, use the Manual Raise/Lower to adjust all four corners until each corner is at your preferred MAXIMUM TRAVEL and the vehicle is level from side to side.

Manual Calibration:
Turn the Ignition OFF. Then hold Program "" Button and the Up "" Arrow while turning the Ignition ON.

The system will then begin adjusting the vehicle throughout its total travel. This process requires no user interaction and should take no more than 15 minutes depending on the size of your Compressor(s) and Tank(s).
Both the "" and "" Arrow will flash slowly during calibration. The "" Arrow will be on when calibration is complete, indicating that the system is at Ride Height (currently saved at 50% of your total travel).
When calibration is complete the positions will be saved as follows:

• Position #1 = 10% of total suspension travel.
• Position #2 = 50% of total suspension travel.
• Position #3 = 90% of total suspension travel.

To re-save these heights to your preference.
