If your vehicle is equipped with a dieselengine, an Intelligent Oil Life Monitor™calculates the proper oil change serviceinterval. When the information displayindicates: OIL CHANGE REQUIRED, changethe engine oil and oil filter. SeeInformation Displays (page 111).
The engine oil filter protects your engineby filtering harmful, abrasive or sludgeparticles and particles significantly smallerthan most available will-fit filters. SeeMotorcraft Parts (page 419).
1. Unscrew the oil filter and oil pan drainplug and wait for the oil to drain.
2. Replace the filter.
3. Reinstall the oil pan drain plug.
4. Refill the engine with new oil. SeeCapacities and Specifications (page427).
5. For diesel engines, you need to resetthe Intelligent Oil Life Monitor™. SeeInformation Displays (page 111).
Engine lubrication for severeservice operation
The following conditions define severeoperation for which engine operation withSAE 5W-40 API CJ-4 is recommended. Oiland oil filter change intervals will bedetermined by the Intelligent Oil LifeMonitor™ as noted previously.
•Frequent or extended idling (over 10minutes per hour of normal driving).
•Low-speed operation/stationary use.
•If vehicle is operated in sustainedambient temperatures below -9°F(-23°C) or above 100°F (38°C).
•Frequent low-speed operation,consistent heavy traffic less than25 mph (40 km/h).
•Operating in severe dust conditions.
•Operating the vehicle off road.
•Towing a trailer over 1,000 mi(1,600 km).

WARNING
Do not dispose of fuel in thehousehold refuse or the publicsewage system. Use an authorizedwaste disposal facility.
Your vehicle has a diesel fuel conditionermodule. The module is mounted betweenthe outboard side of the fuel tank and theframe rail.
Note:The module is at the front of the fueltank or at the front of the aft-axle fuel tankon some models.
You should drain water from themodule assembly whenever thewarning light illuminates or amessage appears in the informationdisplay advising you to drain the waterseparator. This occurs when approximately6.76 fl oz (200 ml) of water accumulatesin the module. If you allow the water levelto exceed this level, the water may passthrough to the engine and may cause fuelinjection equipment damage.
Draining the Diesel FuelConditioner Module
1. Switch the engine off.
2. Access the underside of your vehicle.

The auxiliary switch option packageprovides six switches mounted in theoverhead console. These switches operatewhen the vehicle is running or from batterypower, depending on the switchable fuseAUXF4's location in the upfitter relay box.We recommend, however, that the engineremain running to maintain battery chargewhen using the auxiliary switches forextended periods of time or higher currentdraws.
Note:When your vehicle has a dieselengine, use the auxiliary switches only whenthe engine is running. The glow plugs alsodrain battery power when the ignition key isin the on position. Using the auxiliaryswitches, even for limited amounts of time,can cause your battery to drain quickly andprevent your vehicle from restarting.
When switched on, the auxiliary switchesprovide electrical battery power for avariety of personal or commercial uses.Switches 1 through 4 provide 25 amps.Switches 5 and 6 provide 40 amps.
The relay box for the auxiliary switches isin the rear of the engine compartment,near the back wall. See your authorizeddealer for service.

Intelligent Oil-Life Monitor
Your vehicle has an Intelligent Oil-LifeMonitor that determines when you shouldchange the engine oil based on how youuse your vehicle. By using severalimportant factors in its calculations, themonitor helps reduce the cost of owningyour vehicle and reduces environmentalwaste at the same time.
This means you do not have to rememberto change the oil on a mileage-basedschedule. Your vehicle lets you know whenan oil change is due by displaying amessage in the information display.
The following table provides examples ofvehicle use and its impact on oil changeintervals. It is a guideline only. Actual oilchange intervals depend on several factorsand generally decrease with severity ofuse.
