Camera-based traffic
sign recognition
Description
Applies to: vehicles with camera-based traffic sign recogni­
tion
Fig. 91 Instrument cluster: Traffic sign recognition
Fig. 92 Windscreen: Camera window for traffic sign recog­
nition
Traffic signs detected by the camera appear in
the infotainment display to keep you informed of
current speed restrictions and no-overtaking
zones. In cases where the system is able to de­
tect temporary speed limits applicable in wet
weather r;J or at certain times of day �
¢ Fig. 91 it will also display these traffic restric­
tions.
General notes
The traffic sign recognition system can detect
standardised speed limit signs within the cam­
era's range of vision. It makes use of the naviga­
tion data to evaluate the detected speed limits
and show them on the display. Under certain con­
ditions, the system will also display the legal
speed limits on roads without speed limit signs.
Traffic sign recognition is not available in all
countries. For a current list, see the Internet (e.g.
www.audi.com). The system is also subject to
90 certain
inherent restrictions and may be partially
or completely unavailable in the following situa­
tions:
- If visibility is impaired by snow, rain, fog or
heavy road spray.
- In dazzling light, e.g. from the sun or oncom­
ing traffic.
- At high speeds.
- If the camera's range of vision ¢ Fig. 92 is im-
paired, e.g. by dirt or stickers. Notes on clean­
ing ¢page 263.
- If the traffic signs are partially or completely
obscured, e.g. by trees, snow, mud or other
vehicles.
- If traffic signs deviate from the standard ap­
pearance (round with red border).
- If traffic signs are damaged or bent.
- If matrix traffic signs are mounted on overhead
gantries.
- If traffic signs or routes have changed (naviga-
tion data out of date).
Some types of slow moving vehicles (such as
heavy goods vehicles) carry speed stickers which,
if detected by the system, may affect the display.
A WARNING
Always direct your full attention to the road
and surroundings, even when you are using
traffic sign recognition. The actual traffic
signs on your route always take precedence
over the information on the display. It is al­
ways the driver's responsibility to assess the
traffic situation and take appropriate care.
- Under adverse conditions, the traffic sign
recognition system may misinterpret or fail
to detect traffic signs. It is therefore possi­
ble that the speed limit display may occa­
sionally be unavailable or even incorrect.
- The traffic sign recognition system does not
warn you if you exceed the speed limit and
does not alter the speed of your vehicle to
obey the speed limit.
- The speed limit displayed in the instrument
cluster is given in the units applicable in a
particular country. For example, if SO is dis-
played on the instrument cluster, this may �

restriction in a given situation, it will update the
display accordingly.
Temporary speed restrictions are displayed in the
following situations:
- A temporary speed restriction for wet weather
is detected while the windscreen wipers are op­
erating.
- A speed restriction applying at certain times of
day has been detected and corresponds to the

Audi active Lane assist
(Lane departure warning
feature)
Description
Applies to: vehicles with Audi active lane assist
The active lane assist uses a camera in the wind­
screen to detect lane markings (subject to gener­
al system limitations). If you approach one of the
detected lane markings, the system corrects the
steering to warn you that the vehicle might be
about to cross one of the markings. You can over­
ride this steering input at any time. The steering
wheel vibrates slightly if you cross a lane mark­
ing. The vibration warning must be activated be­
forehand on the infotainment system. The active
lane assist is functional when it detects a demar­
cation line on at least one side of the lane in
which you are driving.
As the system is designed for driving on motor­
ways and other major roads, it is only active
above a speed of about 65 km/h (may vary in dif­
ferent export markets).
Applies to vehicles with side assist*: If you oper­
ate the turn signals while the active lane assist
and side assist are active, the steering will be cor­
rected just before you cross the lane demarcation
if the side assist detects vehicles approaching
quickly or travelling at about the same speed as
your own vehicle and judges the situation to be
critical. This intervention is intended to keep the
vehicle in the lane.
Applies to vehicles without side assist*: The sys­
tem does not warn you if you operate the turn
signal before crossing a lane demarcation. In this
case, it assumes that you intend to change lanes.
A WARNING
- The system initiates a corrective steering in­
put to warn the driver that the vehicle is
about to leave the lane. As the driver you
are always responsible for staying in your
own lane.
l l
The steering input function is not available on all export
versions.
92 -
The system can assist you to keep the vehi­
cle in the lane, however it is not capable of
driving on its own. Never take your hands
off the steering wheel.
- In certain situations, e.g. during heavy brak­
ing, the system may not correct the steer­
ing.
- In certain circumstances, not all of the lane
markings may be detected by the camera. A
corrective steering input can only be initi­
ated if the system detects a lane marking on
the side in question.
- Variations in the road surface or objects on
the road may be misinterpreted as lane
markings. In this case, the steering may be
corrected unexpectedly or not at all.
- The camera's view might be obstructed, for
example by vehicles travelling in front, rain,
snow, a lot of water on the road, adverse
light or dirt on the windscreen. If this hap­
pens, the active lane assist may not detect
the lane markings or may respond incorrect­
ly.
- In certain circumstances, for instance if visi­
bility is poor, the setting for the steering in­
put may be switched
internally
from "early"
to"late" l)_
- In certain driving conditions, such as ruts in
the road surface, adverse cambers or side
winds, the assistance provided by the steer­
ing correction may be insufficient to keep
the vehicle in the middle of the lane.
- For safety reasons, the active lane assist
must not be used in poor weather or in diffi­
cult or slippery road conditions (such as ice,
fog, loose grit or gravel, heavy rain, snow,
etc.) -risk of accident!

Audi side assist (Lane
change assist feature)
Description
Applies to: vehicles with Audi side assist
Fig. 100 Area covered by the radar sensors
Fig. 101 Warning lamp on exterior mirror
The side assist function assists the driver in mon­
itoring following traffic and the blind spots on
both sides of the car. Within certain system Lim- Driver
assist systems
its, it warns you if it detects vehicles approaching
quickly or travelling at about the same speed as
your own vehicle in the area covered by the sen­
sors (!)¢ Fig. 100: if it judges a Lane change to
be critical, the warning Lamp@on the exterior
mirror Lights up¢ Fig. 101.
The warning Lamp on the Left-hand mirror assists
the driver when changing Lane towards the Left
and the warning Lamp on the right-hand mirror
assists the driver when changing Lane towards
the right.
Information mode
As Long as you do not operate the turn signal, the
side assist will merely inform you of the presence
of vehicles that it has detected and judges to be
critical. In this case, the warning Lamp on the rel­
evant exterior mirror will Light up at Low intensi­
ty.
The intensity of the warning Lamp in this infor­
mation mode is kept relatively Low, so that it
does not distract you while you are Looking at the
road in front.
Warning mode
If you operate the turn signal, the side assist will
warn you if it registers what it judges to be a crit­
ical vehicle. In this case, the warning Lamp on the
relevant exterior mirror will flash brightly. Please
check the situation in the exterior mirror and by
Looking back over your shoulder¢ A in General
notes on page 98.

Fig. 102 Driving situations
--'(; --1 ) --
Fig. 103 Rear of vehicle: Location of the sensors (exam­
ple)
The side assist is active above a speed of
about 30 km/h.
@Vehicles approaching from behind
In certain cases, a vehicle is judged to be critical
in the event of a lane change even if it is still
some distance away. The faster a vehicle ap­
proaches, the earlier the warning will appear on
the exterior mirror.
@Vehicles moving at a similar speed
The warning lamp in the relevant exterior mirror
will warn you of vehicles that are moving with the
flow of traffic at about the same speed as you if
98 they
are judged to be critical in the event of a
lane change. In all cases, the side assist will give
a warning for the vehicles it has detected at the
latest when they enter the "blind spot".
@ Other vehicles being overtaken
When you are overtaking another vehicle slowly,
with a speed differential of less than 15 km/h,
the warning lamp in the exterior mirror will light
up as soon as the other vehicle enters your blind
spot.
If you are overtaking another vehicle quickly,
with a speed differential of more than 15 km/h,
the warning lamp will not light up.
System limitations
The radar sensors are designed for normal lane
widths and monitor the lanes immediately to the
left and right of your vehicle. In certain situations
the warning lamp on one of the exterior mirrors
may light up even if no vehicle is travelling in an
area that could be critical in the event of a lane
change. For example:
- When you are travelling in a narrow lane or
when you a re not travelling in the centre of the
lane. In this case the system may monitor an­
other lane and register a vehicle that is not in
fact travelling in an adjacent lane.
- When you are driving into a bend. The side as­
sist may react to a vehicle two lanes away.
- If the system detects other objects (such as
crash barriers, etc).
- In poor weather conditions. The functionality of
the side assist is then restricted.
The radar sensors ¢ Fig. 103 must not be ob­
structed by stickers, bicycle racks, deposits or any
other substances which could impair the function
of the system. For notes on cleaning, please refer
to ¢page 263.
A WARNING
- Always watch the road and the area sur­
rounding the vehicle. The side assist feature
is not a substitute for the full concentration
of the driver. The driver is always responsi­
ble for the safety of lane changes and other
manoeuvres. �
