²Under no circumstances should oil change intervals
exceed 6,000 miles (10,000 km) or 6 months, whichever
comes first.
Your dealer will reset the oil change indicator message
after completing the scheduled oil change. If this sched-
uled oil change is performed by someone other than your

Settingsº of the EVIC section in this manual.

racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.

required.
