Section 7 page 202..."The oil change interval for your crossfire is initially set at 7,000 miles (Canada: 11,000 KM)."
Section 7 page 203..."The Flexible Service System (FSS) in your vehicle evaluates engine temperature, oil level, vehicle speed, engine speed, distance driven, and the time elapsed since your last service. It determines when your vehicle needs maintenance service and alerts you in advance. The next necessary service is indicated by the FSS in your instrument cluster. Observe the oil change interval indicated by your FSS system. The system will monitor the driving conditions seen by your vehicle, and will recommend the best interval for servicing your vehicle to maintain it in top condition."
