2006 Chrysler Pacifica Owner's Manual - Page 296

296 STARTING AND OPERATING Follow the recommended tire rotation frequency for your type of driving found in the "Maintenance Schedules" Section of this manual. More frequent rotation is permissible if desired. The reasons for any rapid or unusual wear should be corrected prior to rotation being performed. The suggested rotation method is the "forward-cross" shown in the following diagram. FUEL REQUIREMENTS Your vehicle is designed to meet all emissions regulations and provide satisfactory fuel economy and performance when using high quality unleaded gasoline having an octane range of 87 to 89 or higher. The manufacturer recommends the use of 89 octane for optimum performance. Light spark knock at low engine speeds is not harmful to your engine. However, continued heavy spark knock at high speeds can cause damage and immediate service is required. Poor quality gasoline can cause problems such as hard starting, stalling and hesitations. If you experience these symptoms, try another brand of gasoline before considering service for the vehicle.
