MAINTENANCE SCHEDULES PARTS AND LUBRICANT RECOMMENDATIONS When service is required, Chrysler Corporation recommends that only Mopart brand parts, lubricants and chemicals be used. Mopart provides the best engineered products for servicing Chrysler Corporation vehicles.

INTRODUCTION The maintenance schedule is divided into emission related maintenance and non-emission related maintenance. Emission related maintenance is defined as those maintenance operations which must be performed at the mileage specified to assure the continued proper functioning of the emission control system. These, and all other maintenance services included in this manual, should be performed to provide the best vehicle performance and reliability. If a vehicle is subjected to the conditions listed below (severe service), maintenance should be performed twice as frequently, for example, every 3 months instead of every 6 months, or every 3,000 miles (4 800 km) instead of every 7,500 miles (12 000 km). • Frequent short trip driving less than 15 miles (24 km). • Frequent driving in dusty conditions. • Trailer towing. • Frequent long periods of engine idling. • Sustained high speed operation. • Desert operation. • Frequent starting and stopping. • Cold climate operation. • Off road driving. • Commercial service.

MAINTENANCE SCHEDULES The service intervals are based on odometer readings in thousands of miles or kilometers. For mileage beyond that listed, continue maintenance services every 7,500 miles (12 000 km) or more frequently for severe conditions.
