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 mainte-
nance may include replacing the Closed Crankcase Ven-
tilation (CCV) filter element. The procedure for clearing
and resetting the “Perform Service” indicator message is
located in the appropriate Service Information.
