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. Required Maintenance Intervals
Refer to the Maintenance Schedules on the following
pages for the required maintenance intervals.
