It does not appear to work. Does anyone have any suggestions?

1. With car engine OFF, hold down both the “ODO TRIP” and “RESET” buttons (located in switch box).
2. Continue holding down buttons, while you start the car.
3. Continue holding buttons (approx. 7 secs) until reset occurs.
If first method does not work, try this:
1. Push the “ODO TRIP” switch in the switch box to
change the display to blank (only odometer mileage showing no trip A or B).
2. Turn the engine switch off.
3. Turn the engine switch on with the trip meter “RESET”
switch held down.
4. Keep pushing the “RESET” switch for longer than 7
seconds after the engine switch is turned on.
After the above operation, the master warning light comes
on, a warning tone sounds and the above message
appears to inform you that the engine oil maintenance
data has been reset.
Good luck.

Tried all of the above mentioned combinations on my GS350 '07 - no luck.

Tried again WITHOUT having ODO button pressed (i.e. Reset only).
Finally got Oil Maint. message reset on my 3GS350AWD2007
Also another note - you do not have to start the vehicle.
1. With ignition on (regardless of the engine status), select your display to the following reading:
-> Upper part of display - Oil Maint. Message (blank in normal conditions).
-> Lower part of display - Odometer reading (NOT Trip A/B!)
2. Turn off ignition.
3. Without touching brake pedal, touch Start button once.
4. You will get Info message on the display
5. Press and hold Reset button (only) on the control panel AND at the same time touch Start button again while still holding Reset button.
6. In 5-10 second display will show confirmation message that Oil Maint was reset.

So obviously the system does not monitor the quality or cleanliness of the oil,just the miles since last change,correct?
