Electronic Air Suspension - 3.9L & 4.2L: Operation: Notes

The Air Suspension System is designed to maintain vehicle height under varying loads or to driver's preference. The system adjusts vehicle height by adjusting volume of air supplied to each air spring located at each wheel. It should be noted that the system is not an active suspension system that controls vehicle's dive and roll during cornering.

The system can operate in any one of five heights or modes: standard, low profile, high profile, access, and extended. The driver has the option of selecting three heights (standard, high profile, or access) using switches on instrument panel. The driver can also inhibit automatic system operation using instrument panel mounted inhibit switch. When system is inhibited, vehicle will revert to standard height and will maintain vehicle levelling. It is recommended that system be inhibited whenever towing a trailer.
