To reset the oil monitoring system to 100% after each oil change [approximately 7,500 miles (12,000 km) or six months] perform the following: 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
