M A I N T E N A N C E S C H E D U L E S 486 MAINTENANCE SCHEDULES 8 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 Information Center (EVIC). The engine oil change indicator system is duty cycle based, which means the engine oil change interval may fluctuate depending on your personal 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 Service" 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 Information.
