got my oil change done and the CHANGE OIL warning still on the screen is there a way to reset that? by the way it was not done at the hummer dealer .

Its in the manual.With car off put key to foward position when miles comes up click the button(reset button for odometer)till oil life comes up then press and hold for a few seconds... that should do it.The acual miles on truck will stay the same it does not reset to 0 .It should have been reset at oil change bring it to there attention next time in. Make sure you sign up online and you will get a monthly report from on star.

Four thanks for the reply . yes u will get ready of it by pressing the botton but everytime u turn on the car u will have to do the same . i call the dealer and the trick to it is sinple turn the key foward without strting the car and hit the gas pedal 3 times in les than 5 seconds and that will get ready of it .

FYI, the Owner's manual talks about it at page 5-17.
