Argghhh! That reminds me in the 80's when GM had the brilliant idea of a flag that would physically pop out beside the odometer every 60k (or was it 30k?) miles to tell you to have the catalytic converter checked and serviced. Except for dedicated DIY'ers, the only way to reset the flag was to take the vehicle into the dealer and have them reset the flag (required partially dismantling the instrument cluster). What a pain!
