The suspension of this vehicle has been optimized for off road utility through installation of an AccuAir

®

 system allowing 

control/adjustment of ride height to accommodate challenging terrain & obstacles. The suspension feel and handling maybe 
different than an unmodified Jeep. 

To reduce risk of roll-over other accident & serious injury always:

• 

Inspect components including bags, lines, valves & compressor before use, followed by system self-test. Maintain & repair 

as indicated. On road height limited to approx. 3.0” by system speed & ride height sensors. 

REPLACE & DO NOT USE ON 

ROAD IF SPEED SENSOR DAMAGED/INOPERATIVE.

• 

DO NOT

 modify or substitute AccuAir

®

 components of this system. Use of oversize tire/wheel combinations may increase 

stopping distances, ride height and/or compromise performance of vehicle stability control and other systems.

CONGRATULATIONS!

corner air bags allowing you to select a ride height tailored to your off road adventures. Back on the road, a unique speed 
sensing value presets ride height to a maximum of 3.0” of lift (approx.), helping to preserve familiar ride comfort. Enjoy

• 

The drag link must be adjusted to center the steering wheel before the vehicle is driven. Failure to do so will cause 
computer errors, odd handling characteristics, and poor performance.

• 

If larger tires (10% more than the OEM diameter) are installed, speedometer recalibration will be necessary. 
Contact your local Jeep dealer.

• 

After installation, a qualified alignment facility is required to align the vehicle to the OEM specification.

• 

Avoid excessive speeds, abrupt maneuvers, surfaces/obstacles 

which may induce a tripping moment. All occupants 

BUCKLE UP &
