Speed limits at certain times of day
Speed limits when towing a trailer
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.
The traffic sign for the currently detected speed
limit will flash on the display if
a
speed warning

threshold,
which has been set on the infotain­
ment system, is exceeded
^page
109.
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
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.
98 is im­

paired,
e.g. by dirt or stickers. Notes on clean­
ing
•=>
page 312.
- 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tion data out of date).
- If the system detects a speed sticker on a slow-
moving vehicle (such as a heavy goods vehicle).
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.

Audi adaptive cruise
control
Description
Applies to: vehicles with Audi adaptive cruise control

»

Fig.
100 Sensor range
The adaptive cruise control is a combined speed
and distance control system. It assists the driver
by controlling the road speed and the distance to
the vehicle in front within certain limits imposed
by the system. The adaptive cruise control sys­
tem can accelerate and brake when it detects a
vehicle in front. This provides maximum comfort
both on long motorway journeys and in conges­
ted traffic (automatic gearbox*).
What can the adaptive cruise control do?
The adaptive cruise control uses a radar. The ra­
dar is subject to certain system limitations

opage
112.
When there is no traffic in front, the adaptive
cruise control works just like a normal cruise
con­

trol system by maintaining a constant speed.
When you draw closer to a vehicLe in front which
is detected by the system, the adaptive cruise
control matches your speed to that vehicle by au­
tomatically applying the brakes, and then main­
tains a constant distance (which you can adjust in
the settings). As soon as it detects no more
vehicles in front, the adaptive cruise control ac­
celerates back up to the cruising speed.
Applies to: vehicles with automatic gearbox
In congested traffic, the adaptive cruise control
can brake down to a standstill and accelerate
again (subject to general system limitations) un­
der certain conditions
*$page
115, Driving in
congested traffic. The traffic jam assist (active
lane assist)* can assist the driver in traffic jams
and heavy congestion
<=>page
117.
Which functions can the driver control?
When you switch on the adaptive cruise control,
you can set your current speed as the "cruising

speed"

on/off.

While you are driving, you can interrupt the
cruise control

In addition, you can adjust the distance to
vehicles in front and the driving program for the

The distance between the two vehicles

When you draw closer to a vehicle in front, the
adaptive cruise control matches your speed to
that vehicle by applying the brakes, and then
maintains a constant distance (which you can ad­
just in the settings). If the vehicle in front accel­
erates, the adaptive cruise control will also accel­
erate up to the target speed you have specified.
The higher the speed, the higher the distance

•=> A-
We recommend using the distance 3 set­

ting.
You will then be following the general rec­
ommendations of automobile clubs, traffic au­

The actual distance maintained by the adaptive
cruise control may be longer or shorter, depend­
ing on the traffic situation and the driving style
of the driver in front.
If you change the gap, the new setting will be
shown briefly on the instrument cluster display,

e.g.
fcjfor distance 3. This only happens when
the adaptive cruise control display is not visible in
the instrument cluster

Distance 1: This setting is equivalent to a dis­
tance of approximately 28 metres at a speed of
100 km/h (time-based distance of approximately
1 second).
Distance 2: This setting is equivalent to a dis­
tance of approximately 36 metres at a speed of
100 km/h (time-based distance of approximately
1.3 seconds).
Distance 3: This setting is equivalent to a dis­
tance of approximately
50
metres at a speed of
100 km/h (time-based distance of approximately
1.8 seconds).
Distance 4: This setting is equivalent to a dis­
tance of approximately 67 metres at a speed of

2.4 seconds).
Distance 5: This setting is equivalent to a dis­
tance of approximately 100 metres at a speed of

When setting the distance, the driver is re­
sponsible for adhering to the locally applica­
ble laws and regulations.

Audi active Lane assist
Description
Applies to: vehicles with Audi active lane assist
The active lane assist (lane departure warning
feature) uses a camera in the windscreen to de­
tect lane markings (subject to general 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 override this
steering input at any time. The steering wheel vi­
brates slightly if
you
cross a lane marking. The vi­
bration warning must be activated beforehand on
the infotainment system. The active lane assist is
functional when it detects a demarcation line on
at least one side of the lane in which you are driv­

ing.

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).

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.
- 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,

Emergency assist
Applies to: vehicles with emergency assist
The emergency assist takes over controL of the
vehicle in certain situations and can help to pre­
vent accidents. It is an extension of the active
lane assist and can use the functions of the adap­
tive cruise control system
<=>^.
The emergency
assist is activated when it detects that the driver
has stopped steering the vehicle.
Functions of the emergency assist
The emergency assist monitors the steering ac­
tivity of the driver. It detects if the driver is inac­
tive and gives repeated visual and audible warn­
ings as well as brake jolts prompting the driver to
take proactive control of the vehicle again. The
hazard warning lights are also switched on when
the first sharp brake jolt is given below
a
speed of
80
km/h15.

If the driver does not take over, the system inter­
venes by steering the vehicle (within the limita­
tions of the system) to keep it in lane, and by ap­
plying the brakes until the vehicle has stopped*.
In addition, the warning lamp || and a message
are displayed.
Requirements for using the emergency assist
- The active lane assist must be switched on and
ready to warn
