Required Maintenance
Refer to the Maintenance Schedules on the
following pages for required maintenance.
At Every Oil Change Interval As Indicated By OilChange Indicator System:
• Change oil and filter.
•
Completely fill the Diesel Exhaust Fluid tank.
• Drain water from fuel filter assembly.
• Rotate the tires. Rotate at the first sign of
irregular wear, even if it occurs before the oil
indicator system turns on.
• Inspect battery and clean and tighten ter- minals as required.
• Inspect brake pads, shoes, rotors, drums, hoses and park brake.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.

CAUTION!
• Mixing of engine coolant (antifreeze)
other than specified Organic Additive
Technology (OAT) engine coolant (anti-

and may decrease corrosion protection.
Organic Additive Technology (OAT) en-
gine coolant is different and should not
be mixed with Hybrid Organic Additive

the cooling system in an emergency, the
cooling system will need to be drained,
flushed, and refilled with fresh OAT cool-
ant (conforming to MS.90032), by an
authorized dealer as soon as possible.
• Do not use water alone or alcohol-based
