To reset the oil monitoring system to 100% after each oil change
[approximately 7,500 miles (12,000 km) or six months] perform the
1. Press and release the SETUP
control to display “OIL LIFE =
XXX% HOLD RESET = NEW”.
2. Press and hold the RESET
control for two seconds and release.
Oil life is set to 100% and “OIL LIFE
SET TO 100%” is displayed.
3. While “OIL LIFE SET TO 100%”
is displayed, if a lower oil life start
value is desired, press and release the RESET control to reduce the start
value. Each press of the RESET control reduces the value by 10 percent.
Note: Oil life start value of 100% equals 7,500 miles (12,000 km) or six
months. For example, setting oil life start value to 60% sets the oil life
start value to 4,500 miles (7,200 km) and 108 days
