I just thought I would post this for people who don't know how to do it. It is in the Owner's Manual, but pretty sure some people just do internet searchs first.
1)Turn the ignition switch to the ON position.
2)Press the Gauge Dimmer knob until "Engine Oil Life" is displayed.
3)Press & Hold the Gauge Dimmer knob for 10 seconds. Then the "Engine Oil Life" & "Maintenance" item codes will blink.
4) Press & Hold the Gauge Dimmer knob for another 5 seconds. and the warning light codes will disappear and "Engine Oil Life" gauge will reset to 100%.
Do this only if you performed the needed maintenance for your vehicle.
