GENERAL MAINTENANCE
INFORMATION - DIESEL
Why Maintain Your Vehicle?
Carefully following the maintenanceschedule helps protect against major repairexpenses resulting from neglect orinadequate maintenance and may help toincrease the value of your vehicle whenyou sell or trade it. Keep all receipts forcompleted maintenance with your vehicle.
It is important that you have your vehicleserviced at the proper times. Theseintervals serve two purposes: first is tomaintain the reliability of your vehicle andthe second is to keep the cost of owningyour vehicle down.
It is your responsibility to have allscheduled maintenance performed and tomake sure that the materials used meetthe specifications identified in this owner'smanual. See Capacities andSpecifications (page 520).
Failure to perform scheduled maintenanceand regularly inspect your vehicle mayresult in vehicle damage not covered bythe vehicle Warranty.
Why Maintain Your Vehicle at YourDealership?
Our Genuine Replacement Parts
Dealerships stock our parts and ourauthorized branded remanufacturedreplacement parts. These parts meet orexceed our specifications. Parts installedat your dealership carry a nationwide24-month or unlimited mile (kilometer)parts and labor limited warranty.
If you do not use our authorized parts, theymay not meet our specifications and couldaffect emissions compliance.
Protecting Your Investment
Maintenance is an investment that paysdividends in the form of improvedreliability, durability and resale value. Tomaintain the proper performance of yourvehicle and its emission control systems,make sure you have scheduledmaintenance performed at the designatedintervals.
Your vehicle comes with the IntelligentOil-Life Monitor system, a messageappears in the information display at theproper oil change interval. This intervalmay be up to one year or 15,000 mi(24,000 km) for the 6.7L Diesel.
When the oil change message appears inthe information display, it is time for an oilchange. Make sure you perform the oilchange within two weeks or 500 mi(800 km) of the message appearing. Makesure to reset the Intelligent Oil-Life Monitorafter each oil change. See NormalScheduled Maintenance (page 597).
If your information display resetsprematurely or becomes inoperative, youshould perform the oil change interval atsix months or 5,000 mi (8,000 km) fromyour last oil change. Never exceed one yearor 15,000 mi (24,000 km) between oilchange intervals.
You can drive high performance vehiclesin such a way that may lead to higher oilconsumption including extended time athigh engine speeds, high loads, enginebraking, hard cornering maneuvers, trackand off-road usage. Under theseconditions, oil consumption ofapproximately 1 quart per 500 miles (1 literper 800 km) is possible. Check the engineoil level at every refueling and adjust tomaintain proper levels to avoid enginedamage.
It is important to rely upon your dealershipto properly diagnose and repair yourvehicle.
