Nissan Repair: service warning, self diagnosis, prev button

Question
I have a Nissan Primera 1.8 02 reg. year 2002. It has a display pannel telling me the temp and is used for climate control and raido crotol etc. At present there is a service warning flashes up everytime i start the engine. My father services the car for me therefore  it does not need to be taken to a garage. Is there any way this warning can be removed without taking it to a garage

Answer
Diane,

I copied this off a link on the web

P12 Service light reset Etc

SELF DIAGNOSIS and CONFIRMATION/ADJUSTMENT MODE
1. START ENGINE.
2. TURN AUDIO SYSTEM OFF.
3. WHILE PRESSING THE INFO SWITCH,TURN THE VOL CONTROL 30 CLICKS OR MORE (dosen't matter which way).
When self diag and conf/adj mode is started a short "beep" will be heard.
Select CONFIRM/ADJUSTMENT.
Select SERVICE.
You should be able to reset and make any adjustments on the screen displayed.
If you need to go back a screen at any stage, use the "PREV" button.
