Exceptions
There are several exceptions to the Normal Schedule:
Rear Axle Maintenance
A rear axle fluid change or level check is not required unless you suspect a leak or the assembly has been submerged in water. During long periods of trailer towing with outside temperatures above
70 °F (21 °C), and at wide-open throttle for long periods above
45 mph (72 km/h), change the rear axle fluid every
24,000 mi (38,000 km) or three months, whichever comes first.
California Fuel Filter Replacement
If you register your vehicle in California, the California Air Resources Board has determined that the failure to perform this maintenance item does not nullify the emission warranty or limit recall liability before the completion of your vehicle's useful life. We, however, urge you to have all recommended maintenance services performed at the specified intervals and to record all vehicle service.
Hot Climate Oil Change Intervals
The normal oil change interval is
3,000 mi (5,000 km) for gasoline vehicles operating in the Middle East, North Africa, Sub-Saharan Africa or locations with similar climates using American Petroleum Institute (API) oils Certified for Gasoline Engines and displaying the API Certification Mark. If API Certified Oils are not available, then it is acceptable to use API SM or SN oils. If API oils are not available, then the oil change interval is
1,750 mi (3,000 km).
Engine Air Filter Replacement
The life of the engine air filter is dependent on exposure to dusty and dirty conditions. Vehicles operated in these conditions require frequent inspection and replacement of the engine air filter and cabin air filter.
Diesel Particulate Filter
Over time, a slight amount of ash builds up in the diesel particulate filter, which is not removed during the regeneration process. The filter may need to be replaced with a new or remanufactured part at approximately
250,000 mi (400,000 km). Actual mileage varies depending on engine and vehicle operating conditions.
In this case, the engine control system sets a service light (wrench icon) to inform you to bring your vehicle to the dealer for service. If there are any issues with the oxidation catalyst or particulate filter system, a service light (wrench or engine icon) sets by the engine control system to inform you to bring your vehicle into a dealer for service.
