pg 403 of the user manual gives the following sequence to reset the maintenance required light: 1) set ODO to Trip A 2) power off the vehicle 3) holding down the kph/MPH button, power up the vehicle 4) continue holding the kph/MPH button until the Maintenance data reset has completed. I had to do this twice before it worked for me, but I may have goofed somewhere the first time. Please note this sequence is different than the one described for the 2010 models...
