Change engine oil display

Have an '03 Sierra 1500 w/4.3L V6. I can not turn off the CHANGE OIL MESSAGE on the display when I start the truck. Any ideas?

Thanks for your time.......

Turn the ignition key to the "ON" position..press the gas pedal to the floor 3 times..the display should start to blink..turn the ingition off..system reset

The information should be in your owners manual

Thanks will try. Nothing in manual about it.

merlin is right, ignition in the on position and press the gas pedel three times to the floor..... automatically resets the computer

Worked. Thanks GMMerlin and bigredtruck. Can't believe there is nothing in manual about this.

Will This Technique Also Work For The Airbag Light On A 96 Sierra?
