2008 DODGE RAM 3500 CHASSIS CAB manual transmission

²Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
²Under no circumstances should oil change intervals
exceed 6,000 miles (10,000 km) or 6 months, whichever
comes first.
Your dealer will reset the oil change indicator message
after completing the scheduled oil change. If this sched-
uled oil change is performed by someone other than your
dealer the message can be reset by referring to the steps
described under ªOdometer/Trip Odometerº under ªIn-
strument Cluster Descriptionº in Section 4 of this
manual.
At Each Stop for Fuel
²Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level whilethe vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add if
required.
Once a Month
²Check tire pressure and look for unusual wear or
damage.
²Inspect the battery and clean and tighten the terminals
as required.
²Check the fluid levels of coolant reservoir, brake
master cylinder, power steering and transmission and
add as needed.
²Check all lights and other electrical items for correct
operation.
