STARTING AND OPERATING 47

Oil Change Indicator System
Ram Truck Pick-Up (2500 and 3500 Models)
Your vehicle is equipped with an engine oil change
indicator system. This system will alert you when it is
time to change your engine oil by displaying the words
“Oil Change Due” on your Electronic Vehicle Informa-
tion Center (EVIC). The engine oil change indicator
system is duty cycle based, which means the engine oil
change interval may fluctuate depending on your per-
sonal driving style. Driving styles such as frequent stop
and go type driving or extended idle time can increase
the frequency of the engine oil change. This is the result
of more frequent regeneration of the exhaust after treat-
ment system, which can decrease the life of the engine oil.
Failure to change the engine oil per the maintenance
schedule can result in internal engine damage.For information on resetting the Oil Change Indicator
message, refer to “Oil Change Due” under “Electronic
Vehicle Information Center (EVIC)/EVIC Warning
Lights” in “Understanding Your Instrument Panel” for
further information.
When prompted by the Engine Oil Indicator System, the
engine oil and filter must be changed. If not prompted by
the Engine Oil Indicator System within 7,500 miles
(12 000 km) or six months since the last oil and filter
change, replace the engine oil and engine oil filter. Under
no circumstances should oil change intervals exceed
7,500 miles (12 000 km) or six months, whichever comes
first.

MAINTENANCE SCHEDULES 137

Ram Truck Chassis Cab (3500, 4500, and 5500
Models)
Replace the engine oil and oil filter every 7,500 miles
(12 000 km) or six months, or sooner if prompted by the
oil change indicator system (if equipped). Under no
circumstances should oil change intervals exceed
7,500 miles (12 000 km) or six months, whichever comes
first.
Perform Service Indicator
Your vehicle will require emissions maintenance at a set
interval. To help remind you when this maintenance is
due, the Electronic Vehicle Information Center (EVIC)will display “Perform Service”. When the “Perform Ser-
vice” message is displayed on the EVIC it is necessary to
have the emissions maintenance performed. Emissions
maintenance may include replacing the Closed Crank-
case Ventilation (CCV) filter element, and cleaning of the
EGR Cooler. The procedure for clearing and resetting the
“Perform Service” indicator message is located in the
appropriate Service Information.
