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tion data out of date).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.

Rest recommendation
General notes
Applies to: vehicles with rest recommendation
Under certain conditions, the system can detect
that the driver needs to take a break.
At the beginning of a trip, the system monitors
the driver's general steering style. Using this as a
reference, the system continuously compares the
current steering input at speeds of between 60
km/h and 200 km/h. If the evaluation of the
steering input implies a lapse in the driver's
con­

centration,
the system will then recommend a
break
^>page
111,
Instrument cluster display.
The rest recommendation function is designed
for journeys on motorways and major roads.
System limitations
The rest recommendation function may misinter­
pret the steering input in certain driving situa­

tions,
such as the following:
- On twisty roads.
- On rough roads.
- In poor weather.
- During performance driving.
- When the driver's attention is distracted.
Resetting the system
The system is automatically reset if
you...

- switch off the ignition.
- release the driver's seat belt and open the driv­
er's door.
- drive slower than 60 km/h for a while. If you
subsequently increase your speed again, the
system will reevaluate the driving style.

/\
WARNING
- Never drive when you are
tired.
As a driver
you are always responsible for ensuring that
you
are
fit to drive.
- On
Long
journeys, make sure to take
quate breaks at regular intervals.

ade-

- The system cannot always tell if
you
need a
break.

systems. Notes on cleaning
^>page
312. Please
bear the above in mind if technical modifications
are made to the front of the vehicle.
The functionality of the adaptive cruise control or
pre sense front systems is restricted in certain
situations:
- Vehicles cannot be detected until they are
with­

in the range of the sensor
^>page
111,

Fig.
100.
- The ability of the system to detect vehicles in
front is Limited when they are too close, travel­
ling out of line, or moving into your lane.
- Vehicles that are not clearly discernible, e.g. a
motorcycle or cyclist travelling in front of you
and vehicles with high ground clearance or a
protruding
load,
are often identified late or are
not detected at all.
-When driving through bends
opage
112.
-When vehicles are stationary
^page
113.
A WARNING
Please always direct your full attention to the

road,
even when you are using adaptive cruise

control.
It is always the driver who is respon­
sible for pulling away safely and maintaining
a safe speed and distance from other vehicles.
The purpose of the adaptive cruise control is
to assist the driver. The driver must always in­
tervene manually to avoid an impending
colli­

sion.
As the driver you are always responsible
for braking in good time.
- For safety reasons, the adaptive cruise
con­

trol must not be used on roads with a lot of
bends or in poor weather or difficult or slip­
pery driving conditions (such as ice, fog,
loose grit or gravel, heavy
rain,
etc.) - risk of
accident!
- When you take a turn-off, drive along a mo­
torway exit lane or pass through roadwork
sections, please temporarily switch off the
adaptive cruise control system. This is to en­
sure that the vehicle does not accelerate to
the cruising speed in such situations.
- The adaptive cruise control system will not
brake the vehicle automatically if
you
rest
your foot on the accelerator pedal. Resting
your foot on the accelerator pedal overrides
the speed and distance control function.
- The adaptive cruise control does not react to
pedestrians, animals or crossing or oncom­
ing traffic.
- Reflecting objects, such as crash barriers,
the entrance to a tunnel, heavy rain or ice
can impair the function of the radar sensor.
© CAUTION
Impacts or damage to the bumper, wheel
arches or underbody can cause misalignment
of the sensor. This can impair the effective­
ness of the adaptive cruise control. Have the
systems checked by a qualified workshop.

Audi pre sense
Introduction
Applies to: vehicles with Audi pre sense
The pre sense functions can take action to pro­
tect the vehicle occupants and other road users in
certain hazardous conditions within the system

limits.

- Because the different on-board systems are

networked,
pre sense basic can detect critical
situations and take preventive action to protect
the occupants.
- The pre sense front uses the data of the radar
sensor to calculate the probability of an
acci­

dent
opage
112. It can detect an impending
collision with vehicles or
pedestrians1^
(subject
to general system limitations). In this case, the
system warns the driver visually, acoustically

and,
if necessary, with a short, sharp brake ap­

plication.
If necessary, it can initiate a partial or

fuLl
brake application in order to reduce the im­
pact speed or, in certain circumstances, to
avoid a collision. In conjunction with pre sense
basic, the reversible tensioners on the front
seat belts are also applied if necessary. Pre
sense front is active even when the adaptive
cruise control* is switched off.
Please observe the general safety warnings

•=>
A in General notes on page 112.
© Note
- Certain pre sense functions are deactivated
when reversing.
- The functions of the pre sense system may
also be unavailable if
a
fault develops in the

ESC
system or airbag control unit.
- Please note that, if the front passenger's
airbag has been deactivated, the reversible
belt tensioner on the passenger's side will
be deactivated as
well.

- Switch off pre sense on private roads and
while the vehicle is being loaded onto a car
transporter, train or ferry, etc. This prevents
the pre sense system from taking action in
an inappropriate situation.
Audi pre sense basic
Description
Applies to: vehicles with Audi pre sense basic
The pre sense basic functions are activated at
speeds above approximately 30 km/h.
The system can activate the following functions
in certain situations:
- Seat belt tensioning (e.g. during hard braking):
The seat belts on the front seats have reversi­
ble tensioners. Provided an accident does not
occur, the belts are loosened again slightly and
kept ready for activation.
- Initiation of the closure process for the
win­

dows and panorama sun roof* (e.g. if the
vehi­

cLe understeers or oversteers).
Audi drive select*: the activation threshold
dif­

fers according to the mode selected.

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).
r\i

.-H

00
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,
the active lane assist may not detect

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.
(2) 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
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 about
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 about
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 are not travelling in the centre of the

lane.
In this case the system may monitor an­
other lane and register a vehicle that is nor 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.
120 must not be ob­
structed by stickers, bicycle racks, deposits or any
other substances which could impair the function
of the system. The side assist must not be used
when towing a trailer. For notes on cleaning,
please refer to
^>page
312.
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.

- In poor weather conditions, such as heavy

rain,
snow or road spray.
- If
you
are travelling in very wide lanes, in
tight bends or over crests. The system
may not detect vehicles in the adjacent
lane because they are outside the area
covered by the sensors.

tion.

Suspension control (Audi magnetic
ride)*

The suspension control uses sensors to collect in­
formation on steering movements, braking and
acceleration input by the driver, road surface
quality, road speed and vehicle Loading. With
Audi drive select you can choose between dynam­
ic and comfort-oriented suspension set-ups (dy­
namic and comfort modes), or opt for
a
more
balanced set-up (auto mode).
Steering
The degree of power assistance can be varied.
Various modes are possible
^>page
133. The
light, indirect steering response in comfort mode
is particularly suitable on long motorway trips,
for instance. The steering has a tighter, more di­
rect feel in dynamic mode.
The steering response is even more agile on
vehicles with progressive steering*.
Audi adaptive light*
The adaptive light system adjusts the light distri­
bution according to the mode selected.
Air conditioner*
The air conditioner runs in a particularly econom­
ical mode when the efficiency* setting is selec­

ted.

The acceleration response is particularly econom­
ical in efficiency* mode.
Audi adaptive cruise control*
The acceleration mode can be varied from com­
fort to sport by changing the setting in drive se­
lect. The setting also determines whether the re­
sponse of the adaptive cruise control to the driv­
ing style of the driver in front is more balanced or
spontaneous. The efficiency* mode chooses a set­
up for maximum economy.

Parking aids
Parking aids
General notes
Applies to: vehicles with rear parking aid/parking system
plus/reversing camera/park assist
Various systems are available to help you when
parking or manoeuvring in tight spaces, depend­
ing on the equipment fitted on your vehicLe.
The rear parking aid gives an acoustic warning if
there are any obstacles behind the car

cépage
135.
When you are parking, the parking system plus
warns you acoustically and optically about obsta­
cles detected in front of and behind the vehicLe

^page
135.
The reversing camera uses the infotainment sys­
tem display to show a picture of the area behind
the vehicle captured by the camera. This picture
helps you to park the vehicle parallel or perpen­
dicular to the roadside. In addition, you are assis­
ted by the functions of the parking system plus

^>page
137.
The park assist helps you to find suitable parking
spaces, to manoeuvre the vehicLe into spaces par­
allel or perpendicular to the roadside and to drive
out of spaces parallel to the kerb

A
WARNING
- Always watch the road and the area sur­
rounding the vehicLe. The electronic systems
cannot replace the full concentration of the
driver. The driver is always responsible for
safety during parking and all other manoeu­

vres.

- Please note that certain surfaces, such as
clothing fabrics, cannot be detected or dis­
played by the system - risk of accident!
- The sensors and cameras have bLind spots in
which neither people nor objects are regis­

tered.
It is particularly important to ensure
that there are no small children or animals
near the vehicLe - risk of accident!
- Always keep a close watch on the area
around the vehicLe and make full use of the
rear-view mirrors.
- Impacts or damage to the radiator grille,
bumper, wheel arches or underbody can
cause misalignment of the sensors. This can
impair the effectiveness of the parking aids.
Have the systems checked by a qualified
workshop.

(T)
CAUTION
- The system may not always be able to de­
tect objects such as the following:
- Chains, trailer draw bars, posts or fences
- Objects above the sensors, such as wall
protrusions, etc.
- Objects with certain surfaces or struc­

tures,
such as wire fences or powder snow
- As your car moves closer to low obstacles,
they may disappear from the sensors' field
of vision. Please note
that
you will no longer
be warned about these obstacles.
- Remember to maintain sufficient clearance
from the kerb to avoid damaging the wheel

rims.

(T)
Note
- In certain situations, a warning may be giv­
en by the system even if there is no obstacle
within range of the sensors. This can be
caused by the following, for instance:
- Certain road surfaces or long grass
- External ultrasound sources, e.g. from
street cleaning vehicles
- Heavy rain or snow or dense exhaust
fumes
-To familiarise yourself with the system, we
recommend
that
you practise parking in a
quiet location or a car park. The weather
and light conditions should be good.
- You can change the display and adjust the
volume and pitch of the beeps

Electronic stabilisation
control (ESC)
Description
The electronic stabilisation control (ESC) increa­
ses the car's stability. It reduces the tendency to
skid and improves the stability and roadholding
of the vehicle. The ESC detects critical handling
situations, such as understeer, oversteer and

wheelspin
on the driven wheels. It stabilises the
vehicle by braking individual wheels or by reduc­
ing the engine torque. The indicator
lamp^
in
the instrument cluster starts flashing as soon as
the ESC intervenes.
The following systems are integrated in the ESC:
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under
braking until the vehicle has reached a virtual

standstill.
You can continue to steer the vehicle
even when the brakes are on
full.
Keep your foot
on the brake pedal and do not pump the brakes.
You will feel the brake pedal puLsate while the
anti-lock brake system is working.
Brake assist system
The brake assist system can shorten the braking
distance. The braking force is automatically boos­
ted if
you
press the brake pedal quickly in an
emergency. You must keep pressing the brake
pedal until the danger has passed. On
vehides

with adaptive cruise control*, the response of the
brake assist system will be more sensitive if you
are too close to the vehicLe in front.
Traction control system (ASR)
In the event of
wheelspin,
the traction control
system reduces the engine torque to match the
amount of grip available. This helps the car to
start moving, accelerate or climb a gradient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes the
spinning wheel and directs the power to the
oth­

er driven wheel (or wheels on quattro* versions).
This function is not available at high speeds.
To prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automatically
if subjected to excessive loads. The vehicLe can
still be driven. The EDL will switch on again auto­
matically when the brake has cooled down.
Steering recommendation
The ESC helps to stabilise the vehicle by changing
the steering wheel torque.

Selective wheel torque control
Selective wheel torque control intervenes when
cornering by braking the wheel(s) on the inside of
the bend individually as required. This enables
precision cornering.
Multicollision brake assist system
The "multicollision brake assist system" can help
to reduce the risk of skidding and further
colli­

sions during an accident. If the airbag control
unit detects that
a
collision has taken place up­
wards of
a
certain speed, the vehicle is braked by
the
ESC.

The vehicle will not be braked automatically if:
- the driver presses the accelerator,
- or the
ESC,
the brake system or the vehicle's
electrical system are not fully functional.
WARNING
- The grip provided by the ESC and the inte­
grated systems is still subject to the physi­
cal limits of adhesion. Always bear this in

mind,
especially on wet or sLippery roads. If
you notice the systems cutting in, you
should reduce your speed immediately to
suit the road and traffic conditions. Do not

let
the extra safety provided tempt you into
taking any risks when driving - this can
cause accidents.
