How to Clear the Change Engine Oil Light on a 1999 Grand Prix

The 1999 Pontiac Grand Prix came with three engine options: a 3.1-liter V-6, a 3.8-liter V-6 and or supercharged 3.8-liter V-6. These engines produced 160, 200 and 240 horsepower, respectively. The 1999 Grand Prix had an optional oil life monitoring system that used your driving style and driving conditions to calculate when the car needed an oil change. Pontiac combined this system with the optional trip computer and displays the oil life in a percentage on the trip computer's display. You must manually reset this system after each oil change.

Things You'll Need

• Ignition key

Instructions

1. Insert the ignition key into the Grand Prix's ignition and turn it to the "Run" position, but don't start the vehicle.

2. Press the "Mode" button on the trip computer -- the display near the center of the dashboard -- until the light next to "Oil Life" lights up.

3. Hold the "Reset" button for about three seconds and observe as the "Oil Life" resets to "100%."

4. Turn the key to the "Off" position and remove it from the ignition.
