On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction In dicator Lamp (MIL) I! in
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illumina tes when
the ign ition is switc hed o n and goes o ut afte r
the engine starts and the idle has stab ilized .
This indicates that the MIL is working proper­
ly .
If the light does not go out after t he e ngine
is started, or illuminates wh ile you are dr iv­
i ng, a mal funct ion may exist in the eng ine sys ­
tem . If the light illuminates, t he catalytic con­
verter could be damaged .
Contin ue driving
with reduced power (avo id­
i ng s ustained high speeds and/o r rap id accel ­
erations) and have the cond ition corrected.
Co ntact your a uthorized Audi dea ler.
If the light i llum inates, the e lectronic speed
li miter may also be mal funct ion ing. Fo r 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) . Thi s is less than the
maximum speed of your vehicle . To reduce the
ri sk of sudden tire failure and loss of control if
the vehicle is ope rated at excessive speeds,
your veh icle also has an electronic speed limit­
er. The electronic speed limiter prevents your
vehicle from going faster than the tire speed
rating . For more information ¢

If the engine control unit receives faulty vehi­
cle road speed signals, the Malfunction Indi­
cator Lamp (MIL)
II will i lluminate. If this
occurs, contact the nearest author ized Audi
dea ler for assistance.
A WARNING
-
Always observe the posted speed limits
and adjust your speed to suit prevailing
road, traffic and weather conditions . Never
drive your vehicle faster than the maxi­
mum speed rating of the tires insta lled.
