SCHEDULED SERVICING— DIESEL ENGINE

Failure to properly inspect and maintain your vehicle could result in a component malfunction and effect vehicle handling and performance. This could cause an accident.

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.

Inspect the batteries, and clean and tighten the terminals as required.

Check the fluid levels of the coolant reservoir, brake master cylinder, and automatic trans- mission, and add as needed.

Change the engine oil filter.

Inspect the exhaust system.

Inspect engine air cleaner filter. Replace the engine air cleaner filter, if necessary.

Inspect the CV/Universal joints.

Check the coolant level, hoses, and clamps.

Inspect front end, and lubricate — If equipped with serviceable fittings.

Inspect and replace the Evaporative System Fresh Air Filter as necessary, replacement may be more frequent if vehicle is operated in extreme dusty conditions.

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. Failure to change the engine oil per the maintenance schedule can result in internal engine damage.

An authorized dealer will reset the oil change indicator message after completing the scheduled oil change. If a scheduled oil change is performed by someone other than an authorized dealer, the message can be reset by referring to the steps described under Instrument Cluster Display page 111.

NOTE:

Under no circumstances should oil change intervals exceed 15,000 miles (24,000 km) or 12 months or 500 hours, whichever comes first.

Replace the engine oil and oil filter every 12,500 miles (20,000 km) or 400 hours, whichever comes first when running greater than 5% levels of biodiesel.

PERFORM SERVICE INDICATOR — CUMMINS® DIESEL

Your vehicle will require emissions maintenance 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.
