!?) Engine speed limitation
A pp lies to ve hicles : w ith e ngin e spee d limit ation
[II Max. engine speed: XXXX rpm
The engine speed is automatically limited to the
speed displayed in the driver information system.
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 once.
If the engine speed limitation was activated by
an engine control malfunction, the
[m indicator
light also turns on. Make sure the engine speed
does not go above the speed displayed, for exam­
ple when downshifting. Drive to an authorized
Audi dealer or authorized Audi Service Facility im­
mediately to have the malfunction corrected.

On-Board Diagnostic
system (OBD)
System indicator light (MIL)
The system indicator light (M IL)
¢4 in the instru­
ment cluster is part of the On Board Diagnostic
System (080 II).
The warning/indicator light turns on when the ig­ nition is switched on and turns off once the en­
gine is started and is running in id le at a stable
speed. This indicates that the MIL is functioning
correctly.
If the light doe s not turn off after starting th e
engine or turns on whi le driving, this may indi­
cate there is a malfunct ion in the engine. If the
26
indicator tu rns on, the cata lytic conve rter may be
damaged.
D rive with reduced engine performan ce (avoid
high speeds for extended per iods of t ime and/o r
fast acceleration) and have the ma lfunction cor ­
rected. See an authorized Audi dealer or author­
i zed Audi Service Facility .
The ind icator may turn on if the e lectro nic speed
li miter is faulty . For add itiona l information, refer
to
c::> page 130, Electronic speed limiter.
The MIL may a lso turn on if the fuel filler cap is
not clo sed corre ctly

On-Board Diagnostics
F ig. 7 Locat ion of Data Link Connector (DLC)
On-Board Diagnostics mon itors the components
of your emission con trol system. Each monitored
component in your engine system has been as­
s igned a code . In case o f a malfunction, the com­
ponent will be identified and the fault stored as a
code in the contro l module memory.
The M IL light m ay also illum inate if there is a
l eak in the on -boa rd fuel 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 230.
In orde r to make an accu rate diagnosis, the s to r­
ed data can only be d isplayed using special d iag­
nostic equipment (generic scan tool for 080) .
In orde r to co nnect the special d iagnost ic equ ip­
ment, push the plug into the Data Link Connector
(DLC). The DLC is located to the r ight of the hood

lock until the vehicle has come to a com­
p lete stop. Otherwise, the steering lock
could engage sudden ly and increase the risk
of an accident.
(D Tips
The operation o f the remote control key can
be temporarily disrupted by interference from
transmitters in the vicinity of the vehicle
working in the same frequency range (for ex­
ample, a cell phone or radio equipment).

When switched on, adaptive light adjusts to
curves depending on the vehicle speed and steer­ing 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 angle at speeds up to approximately 44 mph
(70 km/h) and when 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 turning.
Speed dependent light distribution* -The speed
dependent light distribution adapts the light in
towns and on highways or expressways . Intersec­
tions can also be illuminated on vehicles with a
navigation system* .
Highway light function*
(Vehicles with adaptive light or LED headlights) -
This function adapts the lighting for highway
driving based on vehicle speed .
& WARNING
-Automatic headlights* are only intended to
assist the driver. They do not relieve the
driver of responsibility to check the head­
lights and to turn them on manually accord­
ing to the current light and visibility condi­
tions. For example, fog cannot be detected by the light sensors . So always switch on the
low beam under these weather conditions
and when driving in the dark
io.
-Accidents could occur if you cannot see the
road ahead of you well and if others on the
road cannot see you . Always switch your
headlightsonsothatyoucanseetheroad
ahead of you and others can see your vehicle
from behind.
- The rear fog lights should only be turned on
in accordance with traffic regulations, to
prevent glare for traffic behind your vehicle .
-If the battery has been discharging for a
while, the parking lights may switch off au­
tomatically to conserve the battery charge

for the next time the engine is started. Al·
ways make sure your vehicle complies with
legal regulations regarding sufficient and
safe lighting when parking it. Avoid using
the parking lights for several hours.
- Please observe legal regulations when using
the lighting systems described .
@ Tips
-The light sensor for the automatic head­
lights* is in the rearview mirror mount.
Therefore, do not place any stickers in this
area on the windshield.
- Some functions of the exterior lighting can
be adjusted
¢ page 48 .
-If you turn off the ignition while the exterior
lights are on and open the door, you will
hear a warning tone.
- In some market-specific versions, the tail
lights do not turn on when switching on the
daytime running lights .
- In cool or damp weather, the inside of the
headlights, turn signals and tail lights can
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 service life of the light­
ing.
- A message will appear in the instrument
cluster if there is a malfunction in the light
sensor
