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 dis-
play “Perform Service”. When the “Perform Service” mes-
sage is displayed on the EVIC it is necessary to have the
emissions maintenance performed. Emissions maintenance
may include replacing the Closed Crankcase Ventilation
(CCV) filter element. The procedure for clearing and reset-
ting the “Perform Service” indicator message is located in
the appropriate Service Information.
