No you need reset your self,turn the key until all dash light come on leaves the switch like that for 30 sec.an then go back and tried

1. Turn the ignition to ON do not start.Engine OFF dash board lights ON.
2. Press and release the reset button in the driver information center (DIC) until the OIL LIFE message is displayed.
3. Once the alternating OIL LIFE and RESET messages appear on the DIC display, press and hold the reset stem until several beeps sound. This confirms the OIL LIFE system has been reset.
4. Turn the key to lock. If the CHANGE OIL message comes back on when you start the engine, the ENGINE OIL LIFE system has not reset. Repeat the procedure
Alternate Method
1. Turn the ignition key to ON with the engine off.
2. Fully press and release the accelerator pedal 3 times within 5 seconds. Several beeps sound. This confirms the oil life system has been reset.
3. Turn the ignition key OFF.
4. If the CHANGE/OIL message comes back on when you start the engine, the engine oil life system has not reset. Repeat the procedure
I use the second method, it is more universal and it works for Chevy Venture too.

Try turning the key to the on position without starting the vehicle and press your gas pedal all the way to the floor 3 times within 10 seconds of turning the key to the on postion. If this doesn't work let me know and I'll have another solution.

turn key to on position do not start vehicle, depress gas pedal to floor three times

pump gas pedal three times once you have turn the key to on position before starting.

1. With the ignition key in RUN but the engine off, fully push and release the accelerator pedal slowly three times within five seconds.

2. Turn the key to off.

IF the CHANGE ENGINE OIL light comes back on, the engine life monitor has not reset. Repeat the procedure.

I have noticed personally that I have press my accelerator 5 times. Each vehicle has it's own idiocyncracies

Turn the ignition key to the RUN position. Fully push and release the accelerator pedal 3 times within 5 seconds. If the CHANGE OIL SOON light flashes 2 times, the system is reset. However if the light comes on and stays on for 5 seconds, the system did not reset. Repeat the procedure if the system does not reset.
Best of luck.

. With the ignition key in RUN but the engine off, repeatedly push the trip/reset button until OIL is displayed on the Driver Information Center. 2. When OIL is displayed, push and hold the trip/reset button for five seconds. The number will disappear and be replaced by 100 (indicating 100% oil life remaining). 3. Turn the key to OFF. If the change engine oil message comes back on, the engine oil life monitor has not reset. Repeat the procedure

somtimes you can take the ground cable off battery for a minute and it will reset check engine light
