_& WARNING
--Never rely exclusively on the outside tem­
perature display to determine if a road sur­
face is icy or not. Keep in mind that road
surfaces, especially bridges and overpasses,
could be ice covered and slippery even at an
outside temperat ure above 41 °F (+S °C).
- Always reduce your speed and dr ive with
special care in cold weather conditions when
the chance of encountering icy road surfaces increases .
(D Tips
-You can select the units used for tempera­
ture, speed and other measurements in the
MMI.
- If the vehicle is stationary, or if you are driv­
ing at a very low speed, the temperature
shown in the display might be slightly high­
er than the actual outside temperature . This
is caused by the heat being radiated from
the engine .

System (OBD)
Malfunction Indicator Lamp (MIL )
The Ma lfunction I ndi cator Lamp (M IU ¢.ij in the

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

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

If the engine control unit receives faulty vehicle
road speed signals, the Malfunction Indicator
L amp
(Mil) Ill will illuminate . If this occurs,
