Replace the engine oil and oil filter every 7,500 miles
(12 000 km) or six months, or sooner if prompted by the
oil change indicator system (if equipped). Under no
circumstances should oil change intervals exceed
7,500 miles (12 000 km) or six months, whichever comes

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, cleaning of the EGR
Cooler, cleaning of the EGR Valve, and/or cleaning of the
turbocharger. The procedure for clearing and resetting
the ЉPerform ServiceЉ indicator message is located in the
appropriate Service Information.
