IMPORTANT SAFETY NOTICES
BEFORE SERVICING THE VEHICLE, MAKE SURE TO TURN
OFF “RISE ON START” AND “PRESET MAINTAIN.” THIS WILL
ELIMINATE ANY UNINTENDED SUSPENSION CYCLING IF YOU
NEED TO TURN THE KEY ON IN THE VEHICLE FOR ANY REASON.
ONLY USE THE AIR LIFT PERFORMANCE 3 APP ON A MOBILE
DEVICE WHEN THE VEHICLE IS IN A CLEAR LINE OF SIGHT. TO
AVOID THE RISK OF SERIOUS INJURY OR HARM, VERIFY THAT
NO PERSON OR THING IS NEAR OR IN THE WAY OF THE VEHICLE’S PATH OF TRAVEL WHILE
CYCLING THE SUSPENSION.
FOR USER SAFETY AND TO PREVENT VEHICLE DAMAGE,
THE SYSTEM HAS A 25% OR 25 PSI (1.7BAR) MINIMUM
DRIVE HEIGHT AS THE DEFAULT. DUE TO EXTREME RISK OF
DANGER TO THE USER OR VEHICLE, AIR LIFT COMPANY STRONGLY RECOMMENDS
NOT TO CHANGE THIS VALUE. IF FOR SOME REASON THE MINIMUM DRIVE HEIGHT IS
SET BELOW THE DEFAULT VALUE, AIR LIFT COMPANY SUGGESTS THIS SETTING ONLY
BE USED WHILE THE VEHICLE IS STATIONARY. IT IS POSSIBLE TO SET THE VEHICLE AT A
HEIGHT THAT IS BELOW THIS THRESHOLD, THEN START DRIVING. THIS IS A UNIVERSAL
SYSTEM AND SETTINGS WILL BE DIFFERENT FOR EVERY USER AND VEHICLE. THE
INSTALLER IS RESPONSIBLE TO DETERMINE HOW LOW THE SUSPENSION CAN BE SET
WITHOUT CAUSING DAMAGE. IT IS THE SOLE RESPONSIBILITY OF THE USER, AND AIR
LIFT COMPANY WILL NOT BE HELD LIABLE FOR, ANYTHING THAT MAY HAPPEN TO THE
OPERATOR OR THE VEHICLE AS A RESULT OF THE USER’S CHOICE TO ALTER THESE
DEFAULT VALUES BELOW RECOMMENDED MINIMUMS.
FLOOR JACKS CAN BE DANGEROUS. WHENEVER USING
A FLOOR JACK, MAKE SURE IT IS RATED FOR THE LOAD IT
IS LIFTING. CHECK THE VEHICLE OWNER’S MANUAL FOR
INFORMATION ABOUT WHERE TO PLACE THE JACK. BEFORE RAISING THE VEHICLE,
PLACE WHEEL CHOCKS IN FRONT AND BEHIND THE WHEELS TO PREVENT THEM FROM
ROLLING. ALWAYS USE JACK STANDS TO SUPPORT THE VEHICLE. NEVER GET UNDER OR
PLACE ANY BODY PARTS UNDER A VEHICLE THAT IS SOLELY SUPPORTED BY THE JACK.

WIZARD
Run this program to complete calibration. At
any time, cancel calibration by pressing “stop.”
1. Make sure the vehicle is on a level surface
and select “Yes.”
2. Verify that the front wheels are straight to
prevent damage to fenders, then select
“Yes.”
3. Verify nothing is under the vehicle that
could cause undercarriage damage, then
select “Yes.”
4. Verify that the manifold is securely
mounted, then select “Yes.”
An unmounted manifold will not allow
Preset Maintain to function properly.
5. Determine how many compressors are in
use. If using a single compressor, select
one. If using two compressors with the second compressor harness
(kit number: 27703) select two.
6. The system will ask if it should use manual or automatic pressure
calibration. The user should select manual calibration if ride
pressures will be over 100 PSI (6.9BAR) or if the calibration failed
during automatic calibration.
If automatic calibration fails, try setting max and min pressure values
20-30 PSI (1.4-2BAR) above and below typical ride pressure.
7. If height sensors are installed, select “Yes.” If running as a pressure
only system, select “No.” If only running pressure, system will now
skip to step 8.
8. If height sensors are installed, select whether to calibrate them
automatically or manually. Most vehicles can be calibrated
automatically. The manual option can be used when there is a
custom setup where there may be concern about component
interference at either high or low limits.
9. After selecting “Yes” the system will begin calibration. Selecting
“No” will exit the calibration wizard.
