On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL )
The Ma lfunction I ndi cator Lamp (M IU ¢.ij in the
i nstrument cluster is part of the On-Board Diag­
nostic (OBD II) system .
The wa rni ng/indicator light ill uminates when the
i gnition is sw itched on and goes out after the en ­
gine starts a nd the idle has stab ilized . This indi­
cates that the M IL is working proper ly .
If th e light do es not go out after the eng ine is
started, or illum inates while you are driving, a
malfunct ion may ex ist in the engine system. If
the light illuminates, the catalytic converte r
could b e damag ed .
Cont in ue drivi ng
with redu ced power (avoidi ng
sustai ned high speeds and/o r rapid accelera­
tions) and have the condit ion corrected . Contact
your a uthorized Audi dea ler.
If the l igh t illum inates, the electronic speed lim­
i ter may also be ma lfunctioning. For more infor­
ma tion ¢
page 29, Electronic speed Limiter .
An improperly closed fue l filler cap may also
cause the MIL light to illuminate ¢
page 214.
On-Board Diagnostics
Fig. 17 Locat io n of Data L ink Co nnecto r (DL C)

On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your eng ine system has been as­
signed a code . In case of a malfunction, the com­
ponent 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 system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop ­
erly closed
¢ page 214.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for OBD) .
In order to connect the special diagnostic equip ­
ment, push the plug into the Data Link Connector
(DLC) . The DLC is located to the right of the hood
release
c> fig . 17.
Your author ized Audi dealer or a qualified service
station can interpret the code and perform the necessary repair.
A WARNING
Do not use the diagnostic connector for per­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!
Electronic speed limiter
Your veh icle may be factory equipped with t ires
that are rated for a maximum speed of 130 mph
(2 10 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 operat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter. The electronic speed limiter prevents your vehicle from going faster
than the tir e speed rating . For more information
¢page 243 .
If the engine control unit receives faulty vehicle
road speed signals, the Malfunction Indicator
L amp
(Mil) Ill will illuminate . If this occurs,
contact the nearest authorized Audi dealer for
assistance .
Instruments and indicator lights
S8
Your vehicle 's top speed is elect ronically lim ited
to 155 mph (250 km/h).
If the engine control unit receives faulty vehicle
roadspeed signals, the Malfunction Indicator
Lamp (MIL)¢• will illuminate. If this occurs,
contact the nearest authorized Audi dealer for
assistance.
A WARNING
-A lways observe the posted speed limits and
adjust your speed to suit prevailing road, traf­
fic and weather conditions. Never drive your
vehicle faster than the maximum speed rating
of the tires installed.

A WARNING
--Automatic headlig hts are only intended to
assist the driver . They do not relieve the
driver of his responsibi lity to check the
headlights and to turn them o n manually
according to the cur rent light and vis ib ility
co ndi tion s. For example, fog cannot be

detected by the light sensors. So always
switch on the headlights
io u nder these
weather cond itions 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.
- The rear fog lights should only be turned on in accordance with traffic regulat ion, as the
lights are br ight for following traffic.
- Please obse rve legal regulations when using
the light ing systems described .
@ Tips
-The light sensor* for automatic dynam ic
headlight range control* is located in the
rear view mirror mount . You should there­
fo re not app ly any st icke rs to the windshie ld
i n this area in order to prevent malfunctions
or fail ures.
- In the event of a light sensor malfunction,
the driver is not ified in the i nstr ument clus­

CD Note
-If the mirror housing was moved by outside
forces (such as an impact when maneuver­
ing), you must use the power folding func­
tion to fold the mirror all the way out. The
mirror housing must not be moved back in­
to place by hand because this would impair
the function of the mirror mechanism.
- If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Never fold power folding exterior mirrors by
hand. Only fold them in and out using the
power controls.

A WARNING
Electrolyte fluid can leak from automatic dim­
ming mirrors if the glass is broken. Electro­
lyte fluid can irritate skin, eyes and respirato­
ry system .
- Repeated or prolonged exposure to electro ­
lyte can cause irritation to the respiratory
system, especially among people with asth­
ma or other respiratory conditions. Get
fresh air immediately by leaving the vehicle
or, if that is not possible, open windows and
doors all the way.
- If electrolyte gets into the eyes, flush them
thoroughly with large amounts of clean wa­
ter for at least 15 minutes; medical atten­
tion is recommended .
- If electrolyte contacts skin, flush affected
area with clean water for at least 15 mi­
nutes and then wash affected area with
soap and water; medical attention is recom­
mended. Thoroughly wash affected clothing
and shoes before reuse .
- If swallowed and person is conscious, rinse
mouth with water for at least 15 minutes .
Do not induce vomiting unless instructed to
do so by medical professional. Get medical
attention immediately.
CD Note
Liquid electrolyte leaking from broken mirror
glass will damage any plastic surfaces it
comes in contact with . Clean up spilled elec­
trolyte immediately with clean water and a
sponge.
