Frequent or Extended Idling (Over 10 Minutes Per Hour of Normal Driving) or Frequent
Low-speed Operation if your Vehicle is Used for Stationary Operation
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 protec-
tion) 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
(96,000 km) or 2400
engine hours
Note: When adding coolant additive, do not exceed the specified maximum of
50 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.
Note: After the initial coolant flush and fill at
60,000 mi (96,000 km) or 2400 engine
hours, flush and fill every 45,000 mi (72,000 km) or 1800 engine hours thereafter.

engine hours
Note: When adding coolant additive, do not exceed the specified maximum of 48 fluid
ounces (1.4 liters) for the engine and 16 fluid ounces (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.
Note: After the initial coolant flush and fill at
60,000 mi (96,000 km) or 2400 engine
hours, flush and fill every 45,000 mi (72,000 km) or 1800 engine hours thereafter. Operating in Sustained Ambient Temperatures Below -9.4°F (-23°C) or Above 100.3°F
(38°C)
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.

, inspect the tires for wear and measure
tread depth.
Every
7,500 mi (12,000 km)
Inspect the brake system pads and rotors.
Inspect the air filter restriction gauge. Replace the filter if
necessary.
