tion:
Drive for approximately 15 minutes with these­
lector lever in the S position at a minimum speed
of 37 mph (60 km/h) and an engine speed of ap­ proximately 2,000 RPM. The temperature in­
crease that will result from this can burn off the
soot in the filter. The symbol will switch off when
the cleaning is successful. .,.

The engine speed is automatically limited to the
speed d isplayed in the instrument cluster. This
protects the engine from overheating.
The engine speed limitation deactivates once the
engine is no longer in the critical temperature range and you have released the accelerator ped­
al.
If the engine speed limitation was activated by
an engine control malfunction, the~ indicator
light also turns on . Make sure that the speed
does not go above the speed d isplayed . Drive to
an author ized Audi dealer or authorized Audi
Service Facility immediately to have the malfunc­
tion corrected.

¢ page 25 in the line (D ¢ fig. 5.
_& 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 remember, even if the "snowflake"
symbol (ice warning) does not appear in the
d isp lay, black ice could be on the road.
- Always reduce your speed and drive with specia l care in co ld weather conditions when
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
the engine . .,..

Fuel consumption
The current fuel consumption can be displayed
using a bar ~
fig. 8. The average consumpt ion
(mpg) stored in the short-term memory is also
displayed . When the bar turns green, your veh icle
saves fuel by one of the following functions:
-Recuperation : When the vehicle is coasting or
driving downhill, electrical ene rgy can be stor­

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.
