the vehicle is ope rated at excessive speeds,
your vehicle also has an elect ronic speed limit­
er. The electronic speed limiter prevents your
ve hicl e from going faster than the tire speed
rating. For more information

cle road speed signals, the Malfunction Ind i­
cator Lamp (MIU¢• will illuminate .
If this
occurs, contact the nearest authorized Audi
dea ler for assistance.
