Instruments and indicator lights
indicator turns on, the cata lytic conve rter may be
damaged.
Drive
with reduced engine performance (avoid
high speeds for extended per iods of time and/or
f ast acceleration) and have the malfunction cor­
rected . See an authorized Audi dealer or author­
ized Audi Serv ice Facility.
T he indicator may turn on if the e lectronic speed

On-Board Diagnostics
Fig. 7 Location of Data Link Connector (DLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s igned a code . In case of a mal function, the com­
ponent will be identified and the fault stored as a
code in the control module memory.
T he M IL light may also illuminate if there is a
leak in the on-board fuel vapor recove ry system.
If the light illuminates after a refuelling, stop the
vehicle and make sure the fuel filler cap is prop­
erly closed
qpage 192.
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

Light and Vision
When switched on, adaptive light adjusts to
curves depending on the vehicle speed and steer·
ing wheel angle . This provides better lighting
through the curve. The system operates in a
speed range from approximately 6 mph (10 km/
h) to 68 mph (110 km/h).
Static cornering light* (vehicles with adaptive
light)· the cornering light switches on automati­
cally when the steering wheel is turned at acer­
tain ang le at speeds up to approximately 44 mph
(70 km/h) and whe n the turn signal is activated
at speeds up to approximately 25 mph (40 km/
h). The area to the side of the vehicle is illuminat­
ed better when tu rning.
Speed depend ent light distribution* -The speed
dependent light distribution adapts the light in
towns and on highways or expressways. In tersec­
tions can also be illum inated on veh icles with a
navigat ion system*.
Highway light function*
(Vehicles with adaptive light or LED headlights) -
This function adapts the light ing for highway
driving based on vehicle speed .
..&, WARNING
-Automatic headlights* are only int ended to
assist the driver. They do not relieve the
driver of his responsibility to check the
headlights and to turn them on manually
according to the current light and visibi lity
condit ions. For example, fog cannot be de·
tected by the light sensors . So always switch
on the low beam under these weather con­
ditions and when driving in the dark
io.
- Accidents could occur if you can not see the
road ahead of you well and if others on the
road cannot see you . Always switch your
head lightsonsothatyoucanseetheroad
ahead of you and others can see your vehicle
from behind.
- Please observe legal regulations when using
the lighting systems described .

fog over due to the temperature difference
between the inside and outside . They will
clear shortly after switching them on. This
does not affect the serv ice life of the light­
ing .
