To reset oil change indicator after performing scheduled maintenance, turn ignition on with engine off. Fully depress accelerator pedal slowly 3 times within ten seconds. Turn ignition off. Start engine. If indicator message illuminates when engine is started, repeat reset procedure.

Just did this on my 2009, and it worked.
