Long Rush-hour Traffic
Change the engine oil and filter as indicated by the
information display, and perform the services listed in the
scheduled maintenance chart. As required
Replace the engine-mounted and frame-mounted fuel
filters. Every 15,000 mi
(24,000 km), six months or
600 engine hours
Inspect the coolant concentration, freeze-point protection
and additive, corrosion inhibitor strength. Add coolant
additive if necessary. Every 30,000 mi
(48,000 km) or 1200 engine
hours
Flush and refill the coolant. Do not add coolant additive. Every 60,000 mi

engine hours
Note:When adding coolant additive, do not exceed the specified maximum of 47 fl oz
(1.4 L) for the engine and 20 fl oz (473 ml) for the secondary cooling system. Operating the
engine with excessive coolant additive may cause overheating which could lead to severe,
permanent engine damage.

Exceptions

Schedule:
336
Scheduled Maintenance

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.
