M A I N T E N A N C E S C H E D U L E S 476 MAINTENANCE SCHEDULES † This maintenance is recommended by the manufacturer to the owner, but is not required to maintain emissions warranty. WARNING! You can be badly injured working on or around a motor vehicle. Do only that service work for which you have the knowledge and the right equipment. If you have any doubt about your ability to perform a service job, take your vehicle to a competent mechanic. Maintenance Schedule - Diesel Engine To help you have the best driving experience possible, the manufacturer has identified the specific vehicle maintenance service intervals that are required to keep your vehicle operating properly and safely. Chrysler LLC recommends that these maintenance intervals be performed at your selling dealer. The technicians at your dealership know your vehicle best, and have access to factory trained information, genuine MOPAR parts, and specially designed electronic and mechanical tools that can help prevent future costly repairs. The maintenance intervals shown should be performed as indicated in this section. NOTE: Under no circumstances should oil change intervals exceed 12,500 miles (20 000 km) or 12 months, whichever comes first. At Each Stop for Fuel • Check the engine oil level about 15 minutes after a fully warmed engine is shut off. Checking the oil level while the vehicle is on level ground will improve the accuracy of the oil level reading. Add oil only when the level is at or below the ADD or MIN mark. 8
