v70 service lamp

Look at your odometer/trip meter display. You will note the text "T 1" or T 2" There are 2 trip meter modes, and to toggle between T 1 and T 2, you press the trip reset button briefly. That said, it must be in T 1 to reset the service reminder. Start with the key in the accessory position. Press and HOLD the trip reset button and wait for the mileage to reset to zero. While still holding the button, switch the ignition to the run position, and watch for the previously displayed mileage to return. When it returns, release the reset button, and switch off the ignition. Service reminder is now reset. Some people have noted that the door must be closed for this to work.
