The Malfunction Ind icator Lamp (MIL) ¢'4 i n
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ign ition is switched on and goes o ut after
the engine starts and the idle has stabilized.
Th is indicates that the MIL is working proper­
l y.
If the light doe s not go out after the eng ine

ing, a ma lfunction may exist in the engine sys­
tem . If the light illuminates, the catalytic con ­
verter cou ld be damaged.
Continue driving
w ith reduced pow er (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the condition corrected.
Contact your authorized Audi dealer .
If the light ill uminates, the electronic speed
limiter may also be ma lfunctioning . For more

Electronic speed
limiter
Your vehicle may be factory equipped with tires that are rated for a maximum speed of
130 mph (210 km/h) . Th is is less than the
maximum speed of your vehicle. To reduce the
r isk of sudden tire failure and loss of control if
the veh icle is operated at excessive speeds,
your veh icle also has an elect ronic speed limit­
er. The electronic speed limiter prevents yo ur
vehicle from going faster than the tire speed
rating. For more information~
page 206.
If the engine control unit receives fau lty vehi­
cle road speed signals, the Malfunction Indi ­
cator Lamp (MIL)¢• will illuminate . If this
occ urs, contact the nearest authorized Audi
dealer for assistance.
A WARNING
-
Always observe the posted speed limits and adjust your speed to suit prevailing
road, t raff ic and weather conditions. Never
drive your vehicle faster than the maxi­
mum speed rating of the tires insta lled.
