With the ignition switched on, the warning il­
luminates when at least
one door or the hood
or the rear lid is not closed . The symbol also
shows you
which door(s) or lid is not closed .
In the illustration
c:> fig. 14 it is the driver's

On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL }
The Malfunction Indicator Lamp (MIL)¢• 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 stabilized .
This indicates that the MIL is working proper ­
ly .
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
tem .
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
erat ions) and have the condition corrected .
Contact your authorized Audi dealer .
If the light illuminates, the electronic speed limiter may also be malfunctioning. For more
information
c:> page 29, Electronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c:> page 230.
On-Board Diagnostics
Fig. 15 Location of Data Link Connector (DLC)
On-Board Diagnostics monitors the compo­
nents of your em iss ion contro l system . Each
monitored component in your engine system
has been assigned a code . In case of a mal­
function, the component will be identified
and the fault stored as a code in the control
module memory.
The 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
c:> page 230.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe­
cial diagnostic equipment (generic scan tool
for OBO) .
In order to connect the specia l diagnostic
equipment, push the plug into the Data Link
Connector (OLC). The DLC is located to the
right of the hood release
c:> fig. 15.
Your authorized Aud i dealer or a qualified
service station can interpret the code and per­
form the necessary repair.
A WARNING ""-=--
Do not use the d iagnost ic connector for
personal use. Incorrect usage can cause
malfunctions, which can increase the risk
of a collision!

Electronic speed limiter
Your vehicle may be factory equipped with
tires that are rated for a maxim um speed of
130 mph (210 km/h). This is less than the
maximum speed of your vehicle. To reduce the
risk of sudden tire failure and loss of control if
the vehicle is operated 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 informat ion

If the engine control unit receives faulty vehi­
cle road speed s ignals, the Malfunction Indi­
cator Lamp (MIU
¢..ifi will illuminate. If th is
occurs, contact the nearest authorized Aud i
dealer for assistance.

Your veh icle's top speed is electronically limit­
ed to 155 mph (250 km/h) .

tor Lamp (MIU ¢.jj will illuminate. If th is oc­
curs, contact the nearest authorized Audi

Highway light function* (vehicles with LED
headlights) -this function adapts the lighting
for highway driving based on vehicle speed.
.&_ WARNING
- Automatic headlights are only intended
to assist the driver. They do not relieve
the driver of his responsibility to check
the headlights and to turn them on man­
ually according to the current light and
visibility conditions. For example, fog
cannot be detected by the light sensors.
So always switch on the headlights §.0
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 observe legal regulations when
using the lighting systems described.
(D Note
The rear fog lights should only be turned
on in accordance with traffic regulation, as
the lights are bright for following traffic.
@ Tips
- The light sensor* for automatic dynamic
headlight range control* is located in the
rear view mirror mount. You should
therefore not apply any stickers to the
windshield in this area in order to pre­
vent malfunctions or failures .
- In the event of a light sensor malfunc­
tion, the driver is notified in the instru­
ment cluster display¢
page 22 .
- You will hear a warning tone if you open
the driver door when the exterior lights
are switched on.
- In cool or damp weather, the inside of
the headlights, turn signals and tail
lights can fog over due to the tempera­
ture difference between the inside and
outside. They will clear shortly after switching them on. This does not affect
the service life of the lighting.
