SCHEDULED SERVICING— DIESEL ENGINE
|
CAUTION! |
|
Failure to perform the required maintenance items may result in damage to the vehicle. |
Refer to the maintenance plan on the following pages for the required maintenance intervals. More frequent maintenance may be needed in severe conditions, such as dusty areas and very short trip driving. In some extreme conditions, additional maintenance not specified in the maintenance schedule may be required.
Check the engine oil level at least 30 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.
Inspection and service should also be performed anytime a malfunction is observed or suspected. Retain all receipts.
Using white lithium grease, lubricate the door hinge pivot joints twice a year to prevent prema- ture wear.
Oil Change Indicator System — Cummins Diesel
Your vehicle is equipped with an engine oil change indicator system. This system will alert you when it is time to change your engine oil by displaying the words “Oil Change Due” in your instrument cluster display. The oil change reminder will remind the owner to change the engine oil every 15,000 miles (24,000 km) or 500 hours, whichever comes first, except for the Chassis Cab models configured with optional B20 capability that are using greater than 5% levels of biodiesel, which are 12,500 miles (20,000 km) or 400 hours, whichever comes first. Failure to change the engine oil per the maintenance schedule can result in internal engine damage.
Your authorized dealer will reset the oil change indicator message after completing the sched- uled oil change. If a scheduled oil change is performed by someone other than your autho- rized dealer, the message can be reset by refer- ring to the steps described under “Instrument Cluster Display” in “Getting To Know Your Instrument Panel” for further information.
NOTE:
If Chassis Cab models configured with optional B20 capability are operated with greater than 5% levels of biodiesel, the oil change interval must not exceed 12,500 miles (20,000 km) or 400 hours, whichever comes first under any circumstances. See the Fuel Requirements section for more information regarding opera- tion with biodiesel blend (B6-B20) fuel meeting ASTM specification D-7467.
Your vehicle will require emissions mainte- nance at a set interval. To help remind you when this maintenance is due, the instrument cluster will display “Perform Service”. When the
“Perform Service” message is displayed on the instrument cluster it is necessary to have the emissions maintenance performed. Emissions maintenance may include replacing the Closed Crankcase Ventilation (CCV) filter element. The procedure for clearing and resetting the
“Perform Service” indicator message is located in the appropriate Service Information.
