Please take a moment to review these installation instructions before you begin to install these components on your vehicle. The removal and installation of air suspension products should only be performed by a fully qualified and certified automotive professional.  \nIt is equally important to be aware of all necessary safety measures while installing your new Air Suspension System. This includes proper lifting and immobilizing of the vehicle and isolation of any stored energy to prevent personal injury or property damage.  \nGENERAL INFORMATION  \nReading this manual signifies your agreement to the terms of the general release, waiver of liability, and hold  \nharmless agreement, the full text of which is available at [www.arnottinc.com](www.arnottinc.com) and [www.arnotteurope.com](www.arnotteurope.com).  \nWARNING:  \nThe air suspension system is under pressure (up to 10 bar, or 150 lbf/in). Verify pressure has been relieved and disconnect power to the air suspension system prior to disassembly. Do not allow dirt or grease to enter the system. Always wear standard hand, ear, and eye protection when servicing the air suspension system.  \n• Not to be stored below 5°F (-15°C) and above 122°F (50°C).  \n• Avoid damage to air lines and cables.  \n• Removal and installation is only to be performed by fully qualified personnel.  \n• Use car manufacturer’s diagnostic software.  \nCAUTION:  \nDamage to the vehicle and air suspension system can be incurred if work is carried out in a manner other than specified in the instructions or in a different sequence.  \nTo avoid the possibility of short circuits while working with electric components consult your owner’s manual on how to disconnect your battery.  \nConsult your vehicle owner’s manual, service manual, or car dealer for the correct jacking points on your vehicle and for additional care, safety and maintenance instructions.
