Camera-based traffic
sign recognition
Description
Applies to: vehicles with camera-based traffic sign recogn i­
tion
F ig. 21 Instrument cluster: traffic sign recognition
Fig. 22 Windshield: camera window fo r tra ffic sign recog­
nit ion
Traffic sign recognit ion assists you when driving
by displaying detected speed limits or signs pro­
hibiting passing in the instrument cluster disp lay
~fig . 21. Within the limits of the system, the le­
gal speed limits in school zones are detected and
displayed.
General information
Traffic sign recognit ion can detect standard
speed limit signs that are within the camera's vis­
ual field. With assistance from navigation data,
detected speed limits are evaluated and shown in
the display. The traffic sign for the current de­
tected speed limit will blink in the display if you
exceed the warning threshold set in the Infotain­ ment system
~ page 2 5 .
The traffic sign recognition is subject to certain
system limitations and may be unavailable or on­
ly partially available in the following situations:
24
-when visibility is poor, such as in snow, rain,
fog or heavy spray .
-when there is glare, for example from oncom­
ing traffic or the sun.
- at high speeds.
- if the camera's visual field
~ fig. 22 is covered,
for examp le by dirt or st ickers. For info rmation
on cleaning, refer to
c::> page 33 7.
- if the traffic signs are completely or partially
covered, for examp le by trees, snow, dirt or
other vehicles.
- if speed traffic signs do not conform to the
standards.
- if traffic signs are damaged or bent.
- if traffic signs are d isplayed on sign holders
w ith electronic signs.
- if the traffic signs or the configuration of the
road have changed (navigation data is no lon­
ger up-to-date) .
.&_ WARNING
Pay attention to traffic and the area around
your vehicle when traffic sign recognition is
turned on . The traffic signs installed on the
road always take precedence over the display.
The driver is always responsible for correctly
assessing the traff ic situation.
- Under some circumstances, traffic sign rec­
ognition may not detect traffic signs cor­
rectly or detect them at all. As a result, the
system may not display the correct speed
lim it or any speed limit.
- Traff ic sign recognit ion does not adapt your
veh icle's speed to match the speed limit!
- The display in the instrument cluster is
based on the units of measurement used for
speed in that country. As a result, the dis­
play
SO in the instrument cluster can mean
eithe r km/h or mph, depending on the coun­
try.

Cockpit overview
If the light does not turn off after starting the
engine
or turns on while driving, this may indi·
cate that there is a malfunction in the eng ine. If
the indicator turns on , the catalytic converter
may be damaged.
Drive
with reduced engine performance (avoid
h ig h speeds for extended periods of time and/ or
fast acce leration) and have the malfunction cor­
rected. See an authorized Aud i dealer or author­
ized Audi Service Fac ility .
The electronic speed limiter may be faulty if the
indicator light turns on. For additional informa­
tion, refer to
¢ page 93, Electronic speed limit­
er .
The MIL indicator light may also turn on if the
fuel filler cap is not closed correctly
¢page 298.
On-Board Diagnostics
Fig . 24 Locat ion of Data Link Connector (D LC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
signed a code . In case of a malfunction, the com­
ponent w ill be identified and the fault stored as a
code in the control module memory.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery system .
If the light illuminates after a refuel ing, stop the
veh icle and make sure the fue l filler cap is prop­
erly closed (on ly vehicles with gasol ine engine)
¢page 298.
In order to make an accurate d iagnosis, the stor­
ed data can only be disp layed using specia l diag­
nostic equipm ent (ge ne ric scan tool for OBD) .
26
In order to connect the special diagnostic equip­
ment, push the plug into the Data Link Connector
(DLC). The DLC is located to the r ight of the hood
release
¢ fig. 24.
Your authorized Audi dea le r or qualified work­
shop can interpret the code and perform the nec­
essary repair.
_& 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!
Indicator lights
Description
The indicator lights in the instrument cluster
