Change Engine Oil
The oil change interval for your Crossfire is initially set at
7,000 miles (Canada: 11,000 km).
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.
