I can confirm this will work if you already have the "red car on a lift" icon displayed - as others have noted, wait for the red car to be replaced by the time, and then press the trip reset button.
You won't get the triangle, however - you'll be dumped right into the service menu as far as I can tell.
Wait a second or so after you see your first icon, then let the reset button go.
1: put fob in
2: hit the stop/start button
3: wait for the time to appear
4: depress and hold the trip reset button
5: Wait for the first icon to be displayed
6: After 1 second of the icon being displayed, let the trip button go
