Dodge 2008 Ram 4500 - Manual (Page 488)

Oil Change Indicator System
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 Required” on your Electronic Vehicle Infor-
mation 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 can increase the frequency of the
engine oil change. This is the result of more frequent
regeneration of the exhaust aftertreatment 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 Required – If Equipped,”
under “System Status (EVIC Displays)” in the “Electronic
Vehicle Information Center (EVIC)” Section of this
manual.
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 includes replacing the Closed Crankcase
Ventilation (CCV) filter element, cleaning of the EGR
Cooler, and cleaning of the EGR Valve. The procedure for
clearing and resetting the
ЉPerform ServiceЉ indicator
message is located in the appropriate Service Informa-
tion.
