Volvo: Reset Engine Service Light, volvo s 70, trip odometer

Question
How do I reset the Engine Service Light on my 1999 Volvo S-70 AWD Turbo?  I tried following the instructions provided by the used car dealer but haven't been successful.  I think the light is just telling me I need to change the oil (every 7500 miles) which I've already done.  Thanks!

Answer
Mark,
Proceed as follows to reset the service reminder indicator (SRI):
Ignition position I
Press and hold in the reset button for the trip odometer
Ignition position II
The service reminder indicator (SRI) starts flashing when the reset button for the trip odometer has been pressed for 10 seconds
Release the reset button for the trip odometer within 5 seconds. The instrument gives an audible signal when resetting has succeeded.
Note!  If the trip meter reset button is not released within 5 seconds the indicator is not reset. However the indicator will stop flashing.
