Warranty and Returns Policy Installing the AutoPilot V2 Kit
INSTALL COMPONENTS
LAYOUT: plan component location rst. Prior to mounting components, check to make sure
the electrical harness connections will reach the manifold and compressor, the compressor
leader hose will reach the tank, and the plumbing will route cleanly through the vehicle.
Be sure to install all components as far as possible from any heat sources. Plan and prepare
harness and plumbing routing thru the vehicle: eliminate all sharp edges that could chafe,
use grommets when passing through compartment walls.
Air Compressors ingest moisture and will deposit it inside the tank. The AutoPilot V2 system
does not include moisture separators or lters, and does require periodic tank moisture
removal. If using an Engine Driven compressor, proper oil and water ltration must be added
as these compressors will quickly contaminate the air suspension system.
Compressor
• Prepare Compressor Intake: if inside vehicle, attach lter to port on end of compressor
(Fig. 10). If compressor is located outside vehicle, snorkel inlet lter to dry location
• Center punch and drill four ¼” diameter holes using the compressor itself as a template
• Attach using hardware supplied with compressor
Manifold
• Position manifold in its desired location: make sure manifold mount surface is at
• Fasten using the two provided self-tapping screws. If mounting surface not at, add
washers to space the manifold up over surface irregularities
Tank Pre Assembly (see g. 10) NOTE: compressors ingest moisture and will deposit
water in the tank. Tanks must be regularly purged – be sure to provide easy access to
Drain/Fill Valve (preferably outside the vehicle).
• Apply thread sealant as necessary
• Determine tank location and orientation prior to installing ttings
• In the lower most tank bung, install Drain/Fill PTC Fitting
• Choose a bung for the compressor tting
• Choose highest tank bung for manifold airline routing
• Plug the remaining tank ports with hex plugs
Tank Install (see g. 10)
• Use tank feet as template, drill holes for hardware assembly
• Attach tank using supplied hardware
• Cut appropriate length of hose from the manifold port 5, to the PTC tting on tank
Use a standard hose cutter or razorblade. Cut all hose ends square and as smooth as
possible

MANUAL Mode
MANUAL mode allows the user to ll or exhaust each spring. The display will show arrows
above and below the pressures to indicate the manual control mode. The arrow will be solid
when the spring is lling / exhausting, and just the outline when not active.
The system detects button press time: for a very short (<0.1sec) duration press, the system
will open the valves for a dened “burst”, changing pressure minimally so Users can ne-
tune their pressures. For a longer than 0.1sec press, the valves open as a toggle switch.
If a button is held active the ll / exhaust will timeout at 10 seconds.
• If the display is in standby (dimmed screen backlight) the 1st button press will wake up
the display, and the 2nd button press will actuate the manual ll / exhaust

AutoPilot V2 is an advanced Pressure-Based Air Suspension Control System, using State-
of-the-Art software algorithms to “calibrate” or map the Control System to your vehicle. Once
the system is calibrated, the algorithm predicts required Valve Open Time to move the air
suspension to achieve Preset target pressures. AutoPilot V2 has 8 programmable Presets,
allowing the user to input 8 different combinations of the 4 corner air spring pressures.
After installing AutoPilot V2 in your vehicle, please follow the steps below to properly setup
your new system! If changes are made after installing and calibrating the system such as
changes to air springs, lines, tank, compressor the system must be recalibrated.
SYSTEM CALIBRATION AND SETTINGS
1. Install the AutoPilot V2 air suspension control system.
2. Key-on Power up, compressor should come on to ll the tank.
3. Press Button 1+5, hold for 5-10 seconds to enter “Settings and Diagnostics” mode main
page (g. 2).
4. Press Button 1: TANK ADJUST. Set tank pressure preference by pressing MIN and MAX
up/down buttons (g. 3). Press Button 1+5 to exit to Settings Main Page.
5. Press Button 2 to enter CALIBRATE (g. 4). Press “FULL” Button 5, follow instructions
to calibrate AutoPilot V2 system to your vehicle. Once calibration is complete, Press
Button 1+5 to exit to Settings Main Page.

Now that your system is setup, its time to use it. If changes are made after installing and
calibrating the system such as changes to air springs, lines, tank, compressor the system
must be recalibrated.
There are two “modes”: PRESET, and MANUAL. Pressing button 1&5 together will toggle
between modes. After 10 seconds of non-use, the Display enters “standby” where the LCD
dims. Any button hit will “wake-up” the display and allow users to activate the system: see
Mode operation below:
PRESET Mode
• 1st Button press will display the programmed preset: users can quickly view each preset
prior to activating to make sure they are selecting the desired Preset
• 2nd button press of the same Preset will activate it: the system will iterate up to 5 times
to achieve the Preset target pressures by +/- 3 psi. Display shows “PLEASE WAIT”
as it iterates, then will ash “SUCCESSFUL” when achieved or “STOPPED / FAILED”
if not able to achieve the target pressure window. NOTE: if your system is not hitting
Presets quickly, change the “ADJ” value. Enter “Settings and Diagnostics” mode (press
Button 1+5 for more than 5 seconds), press #2 CALIBRATE, then ADJ to toggle the value
between 0 and 10; higher values increase system ll rates to overshoot target pressures.
• If more accuracy is desired, double press the same Preset and the system will rene
pressures closer to Target

NOTE: Preset 1 should always be entered as the desired “Ride” pressure. AutoPilotV2
has a “Rise on Start” function that when enabled, checks actual Air Spring Pressure and
energizes the Valves to quickly achieve target Pressures in Preset 1, allowing the user to
drive away seconds after vehicle Key-On.
1. Determine Ride Pressures: press button 1+5 to toggle display to MANUAL MODE.
Manually activate each corner (see “Manual Mode” section page XX) to achieve optimal
Ride Pressure, checking vehicle height visually and driving the vehicle to make sure
Corner Pressure is adequate for normal everyday driving. (g. 11)
2. Program Preset 1: press button 1+5 to toggle display to PRESET MODE. Press and hold
Button 1 to set PRESET 1: release button and actual air spring pressures will appear
(g. 12). Fine-tune the pressures by pressing up/down buttons. Press + Hold to scroll.
Press Button 1+5 to exit.
3. You are now free to program the additional 7 Presets to desired pressures. Typical
Presets can be:
− “Low”: set pressures to the lowest possible pressures for extreme low driving stance (g. 13)
− “Front up”: for speed bump or driveway clearance
− “Rear up”: for added load of passengers, equipment (g. 14)
− “Play”: for those that want to enjoy their air suspension freedom, AutoPilot V2 has a
special function that recognizes side-side Presets. When Left side pressures are equal,
and Right side pressures are equal but >25psi different than Left, the algorithm will
activate side to side instead of front to back. It will also equalize all air spring pressures
when exiting the “Play” preset, conserving air by using the high pressure side to inate
the low pressure side. Pairing two “Play” Presets together allows side-side activation
that consumes far less air than Manual Mode activation would consume. Figs. 15 & 16
