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 remember, even if the "snowflake"
symbol (ice warning) does not appear in the

the chance of encountering icy road surfaces
increases .
(0 Tips
- 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

On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢..ifi in the
instrument cluster is part of the On-Board Diag­
nostic (OBD II) system .
The warning/indicator light illuminates when the
ignit ion is switched on and goes out after the en ­
gine starts and the idle has stabilized . This indi­
cates that the MIL is working properly.
If the light does not go out after the engine is
started, or illuminates wh ile you are driving, a
28
malfunction may exist in the engine system. If
the light illuminates, the catalytic converter
could be damaged.
Continue driving
with reduced power (avoiding
sustained high speeds and/or rapid accelera­
tions) and have the condition corrected . Contact
your authorized Audi dea ler.
If t he light illuminates, the electronic speed lim­
iter may also be ma lfunctioning. For more infor­
mation ¢
page 29, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c::;;, page 210.
On-Board Diagnostics
Fig. 16 Loca tion of Data Link Connector (DLC)
On-Boa rd Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s ig ned a code . In case o f a malfunct ion, the com­
pon ent will be identified and the fault stored as a
code in the contro l module memory.
The MIL light may also illum inate if there is a
leak in the on-boa rd fuel vapor recovery system.
If the light illuminates after a refuelling, stop
the vehicle and make sure the fuel filler cap is properly closed
c::;;, page 210.
In order to make an accu rate 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 r:!>
fig. 16. ..,.

Your authorized 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
(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 operat­
ed at excessive speeds, your vehicle a lso has an
electronic speed limiter. The electronic speed limiter prevents your vehicle from going faster
than the tire speed rating. For more information
c::;, page 238 .
If the engine contro l unit receives faulty vehicle
road speed signals, the Malfunction Indicator
Lamp (MIL)
¢4 will illuminate . If this occurs,
contact the nearest authorized Audi dealer for
assistance .
S models
Your vehicle's top speed is e lectron ically limited
to 155 mph (250 km/h).
If the engine contro l unit receives faulty vehicle
roadspeed signa ls, the Malfunction Indicator
Lamp (MIL)
¢4 will illuminate. If this occurs,
contact the nearest authorized Audi dealer for
assistance .
A WARNING
Always observe the posted speed limits and
adjust your speed to suit prevailing road, traf­
fic and weather cond it io ns. Never drive your
vehicle faster than the maximum speed rating
of the tires installed.
