Your vehicle will require emissions maintenance
at a set interval. To help remind you when this
maintenance is due, the instrument cluster will
display “Perform Service”. When the “Perform
Service” message is displayed on the instrument
cluster 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 resetting the
“Perform Service” indicator message is located in
the appropriate Service Information.
