On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) II in
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ignition is switched on and goes out after
the engine starts and the idle has stabi lized .
This indicates that the MIL is working proper­
l y.
If the light does not go out after the engine
is started, or illuminates while you are driv­
ing, a malfunction may exist in the engine sys- tern.
If the
light illuminates, the catalytic con­
verter could be damaged.
Continue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the condition corrected.
Contact your authorized Audi dea ler.
If the light illuminates, the electronic speed
limiter may also be malfunct ioning. For more
information
q page 31, El ectronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
~page 212.
On-Board Diagnostics
Fig. 18 Locat ion of Data L ink Connector (DLC)
On-Board Diagnostics monitors the compo­
nents of your em ission control system . Each
monitored component in your engine system
has been assigned a code . In case o f a mal­
function, the component will be identified
and the fault stored as a code in the control
module memory.
T he MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery sys­
tem.
If the light illuminates after a refueling,
stop the vehicle and make sure the fuel filler
cap is properly closed
q page 212.
In order to make an accurate diagnosis, the
stored data can on ly be displayed using spe ­
cial diagnostic equipment (generic scan tool
for OBD).
In order to connect the special diagnostic
equipment, push the plug into the Data Link ..,.

Connector (DLC). The DLC is located to the
right of the hood release¢
fig. 18.
Your authorized Audi dealer or qualified work­
shop can interpret the code and perform the
necessary repair.
~ WARNING
Do not use the diagnostic connector for
personal use. Incorrect usage can cause
malfunctions, which can increase the risk
of a coll is ion!
Electronic speed limiter
-
Your veh icle may be factory equipped with
tires that are rated for a maximum speed of 130 mph (210 km/h). This is may be less than
the maximum speed of your ve hicle. To reduce
the risk of sudden tire failure and loss of con­
trol if the vehicle is operated at excess ive
speeds, your vehicle has an e lectronic speed
limiter. The electronic speed limiter prevents
your vehicle from going faster than the t ire
speed rating. For more information
¢page 241.
If the engine contro l unit receives fau lty vehi ­
cle roadspeed signals, the Malfunction Indica­
tor Light (MIL)
(llllij will illuminate . If this oc­
curs, contact the nearest authorized Audi
dealer 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 .

adaptive light*
When switched on, adaptive light adapts to
curves in the road depending on the vehicle
speed and the steering angle. This provides
b etter lighting through the curve . The system
operates at speeds between app roximately
6 mph (10 km/h) and 68 mph (110 km/h).
Static cornering light* (vehicles with adaptive
light) - the cornering light switches on at
speeds up to approximately 25 mph (40 km/
h) when a certain steering wheel angle is
reached or when a turn signal is activated. The
area to the side of the vehicle is illuminated
better when turning .
The adaptive light and the co rnering light only
function when the switch is in the AU TO posi­
tion (automatic headlights*) .
A WARNING
--
- Daytime running lights and automatic
headlights* are only intended to assist
the driver . They do not relieve the driver
of his responsibility to check the head­
lights and to turn them on manually ac­
cording to the current light and visibility
conditions. For example, fog cannot be
detected by the light sensors*. So always
switch on the headlights
io under these
weather conditions and when driving in
the dark.
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists. Always turn on
the headlights so that you can see ahead
and so that others can see your car from
the back.
- Please obey all laws when using the
lighting systems described here.

on in accordance with traffic regulation, as
the lights are bright for following traffic. ..,.

(D Tips

l ocated in the rear view m irror mount.
You should therefore not apply any st ick­
ers to the windsh ield in this area in order
to prevent malfunctions or failures .
