Engine Oil Change

message displays, have the engine oil
and filter changed within the next

conditions, the engine oil life system may
not indicate the need for vehicle service for
up to a year. The engine oil and filter must
be changed at least once a year and the oil
life system must be reset. Your trained
dealer technician can perform this work.
If the engine oil life system is reset
accidentally, service the vehicle within
5 000 km/3,000 mi since the last service.
Reset the oil life system when the oil is
changed. See
