impala

does anyone know how to reset the message center on an 04 impala? message showing is (change engine oil) which i have already done, but message is still showing.

There is two ways: turn off the stock radio and hold the DISP button down until you hear a beep and see menu options come up. You'll be able to reset the tire pressure monitor here as well.

Or:

Tire Pressure Monitoring System
- Turn ignition to ON (do not start engine)
- Turn exterior lamp control from OFF to Parking Lamps (middle setting) 3 times in succession.
- Turn ignition to OFF

The system takes 15 to 20 minutes of driving in 3 speed ranges to "learn" the tire pressures. The speed ranges are 15-40 mph, 40-65 mph and +65 mph. After the learn is complete, if a tire is measured to be 12 psi lower than the others for 2-8 minutes, the system will flash a warning.

Change Engine Oil Message
- Turn ignition to ON (do not start engine)
- Fully press the and release the accelerator pedal three times within 5 seconds. If the CHANGE ENGINE OIL message flashes, the system is reset. If not, turn ignition to OFF and repeat the process.
