&_ WARNING
--
- Never rely exclusively on the outside
temperature display to determine if a
road surface is icy or not. Keep in mind
that road surfaces, especially bridges
and overpasses, could be ice cove red and
slippery even at an outside temperatu re
above 41 °F
(+5 °().
-Always remember, even if the "snow­
f la ke" symbo l (ice warning) does not ap­
pear in the disp lay, black ice could be on
the road.
-Always reduce your speed and d rive with
special care in cold weather cond itions
when the chance of encountering icy road surfaces increases.
(j) Tips
- At temperatures below 14 °F (+ 5 °C) a
snowflake symbol appears ahead of the
temperature display.

On-Board Diagnostics
Fig. 14 Locat io n of Data Link Co nnec tor (DLC)
On-Board Diagnostics monitors the compo­
nents o f your emission control 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 a lso illuminate if there is a
leak in the on-board fue l vapor recovery sys­
tem. If the light illuminates after a refuelling,
stop the veh icle and make sure the fuel filler
cap is properly closed
c:> page 220.
In order to make an accurate diagnosis, the
stored data can only 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
c:> fig . 14.
Your authorized Audi dealer or a qualified
service station can interpret the code and per­
form the necessary repair .
Electronic speed limiter
Your vehicle may be factory equipped with
tires that are rated for a maximum speed of 130 mph (210 km/h). This is less than the
maximum speed of your vehicle. To reduce the
risk of s udden tire failure and loss of control if the vehicle is operated at excessive speeds,
your vehicle a lso has an e lectronic speed limit­
er . The e lectronic speed limiter prevents your
vehicle from going faster than the tire speed
rating. For more information
c:> page 249.
If the engine control unit receives faulty vehi­
cle road speed signals, the Ma lfunction Indi­
cator Lamp (MIL)
(lllli$ will illuminate . If this
occurs, contact the nearest authorized Audi
dealer for assistance .
_&. WARNING
-Always observe the posted speed lim its
and adjust your speed to suit prevailing r oad, traffic and weather cond itions. Never
drive your vehicle faster than the maxi­ mum speed rating of the tires installed.
