Audi adaptive cruise
control and braking
guard
Introduction
A ppl ies to: ve hicles with Audi adaptive cruise co ntro l
The adaptive cruise contro l system assists the
driver by regulat ing vehicle speed and helping to
maintain a set distance to the vehicle ahead,
within the limits of the system.
If the system de­
tects a moving vehicle up ahead, adaptive cruise
control can brake and then accelerate your veh i­
cle. This helps to make driving more comfortable
both on long highway stretches and in stop-and­
go traffic.
The braking guard system can warn you about an impending collision and initiate braking maneu­
vers¢
page 85.
Adaptive cruise control and braking guard have
technical limitations that you m ust know, so
please read this section carefully, understand
how the system works and use them properly at
all times.

Fig. 86 Front of th e veh icle: sensors and vi deo camera
The areas that contain the radar and u ltrason ic
sensors and the video camera¢
fig. 86 must nev­
er be covered by stickers o r other objects or ob­
structed with dirt, insects, snow or ice that wi ll
interfere with the adaptive cruise control system
and braking guard. For information on cleaning, refer to
¢
page 193. The same applies for any
modifications made in the front area.
The function of the adaptive cru ise control sys­
tem and braking g uard is limited under some
conditions:
- Objects can on ly be de tected when they are
w ith in sensor range¢
page 81, fig. 89.
- The system has a limited ability to detect ob­
jects that are a short d istance ahead, off to the
side of your vehicle or mov ing into your lane .
- Some kinds of veh icles are hard to detect; for
examp le motorcycles, veh icles w ith high
gro und clea rance or overhanging loads may be
detected when it is too late o r they may not be
detected at all.
-When driving through curves

_& WARNING
A lways pay attention to traff ic when adaptive
cruise control is sw itched on and brak ing
guard is active . As the driver, you are still re­
sponsible for starting and for maintaining
speed and distance to other objects. Braking
guard is used to assist you. The driver must
always take act ion to avoid a collision . The
driver is always respons ible for braking at the
cor rect time.
- Improper use of adaptive cruise control can cause collisions, other accidents and ser ious
pe rsonal injury.
- Never let the comfort and conven ience that
adapt ive cr uise control and braking g ua rd
offe r dist ract you from the need to be a lert
to traffic conditions and the need to remain
in full control of your vehicle at all times,
- Always remember that the adaptive c ruise
control and braking gua rd have limits -they
will not slow the vehicle down or maintain the set distance when you drive towards an
obstacle or something on or near the road
that is not moving, such as vehicles stopped
in a traffic jam, a stalled or disabled vehicle.
If reg istered by the radar sensors, vehicles
or obstacles that are not moving can trigger
a collision wa rning and if confirmed by the
video came ra, an acute co llision wa rning.

Audi adapt ive crui se con trol a nd b rakin g guar d
-For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy ra in and hydroplan­
ing). Using the system under these condi·
tions co uld result in a collision.
- Switch adaptive cruise control off tempora­
rily when driving in turn ing lanes, on ex­
pressway exits or in construction zones. Th is
prevents the vehicle from accelerating to
the set speed when in these situat ions .
- The adapt ive cr uise control system will not
brake by itself if you put your foot on the ac­
celerator peda l. Doing so can override the
speed and distance regu lation.
- When approaching stat ionary objects such
as stopped traffic, adaptive cruise control
will not respond and braking guard will have limited function.
- The adaptive cruise control system and
braking guard do not react to people, ani­
mals, objects crossing the road or oncom ing
objects.
- The function of the radar sensors can be af­
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.
- Never follow a vehicle so closely that you
cannot stop your vehicle safely. The adap·
t ive cruise control cannot slow or brake the
vehicle safely when you fo llow another veh i­
cle too close ly. Always remember that the
automatic braking function ca nnot br ing the
vehicle to a sudden o r emergency stop un­
der these conditions .
- To prevent unintended operation, always
switch ACC off when it is not be ing used .
(D Note
The sensors can be displaced by impacts or
damage to the bumpe r, whee l housing and
unde rbody. That co uld affect the adaptive
cruise control system and braking guard .
Have your authorized Audi dealer or author­
ized Audi Service Facility check their function.

In curves
Applies to: vehicles with A udi adaptive cruise control
Fig. 87 Example : dr iving into a curve
When driving into a curve c:::> fig. 87 and out of a
curve, the adapt ive cruise control may react to an
object in the neighboring lane and apply the
brakes . You can prevent that by pressing the ac­
ce lerator pedal br iefly.
Stationary objects
Applies to: vehicles with Audi adaptive cruise control
Fig. 88 Example: object chang ing lanes and stat ionary ob ·
jec t
The adaptive cruise control system only reacts to
objects that are moving or that the system has
already detected as moving . For example, it can
react when a vehicle that has already been de·
tected @ turns or changes lanes, but adaptive
cruise control does not react to a stationary vehi­
cle @.

Description
Applies to: vehicles with Audi adaptive cruise contro l
Fig. 96 Instrument cluster: approach warning
Braking guard uses radar sensors and a video
camera. It also functions within the limits of the
system when adaptive cruise control is switched
off.
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes suddenly
or if your own veh icle is traveling at a high speed
and approaching a vehicle up ahead that is mov­
ing more slowly. Braking guard does not react if
it cannot detect the si tuat ion.
The system advises you of various situations:
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If the
vehicle ahead brakes sharply, you will not be
able to avoid a collision . T he indicator light .
in the d isplay comes on .
- The
approach warning is given when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply.
When this warning is g iven, it may only be pos­
s ib le to avoid a collision by swerving or braking
sharp ly. The indicator light. and indicator in
the display will warn yo u about the danger
¢
fig. 96. You will also hear an acoustic signa l.
If you do not react fast enough or do not react at
all to the situation, braking guard will intervene
by braking.
N "' ll This is not available in some countries . ......
-If a collision is imminent, the system wi ll first
provide an
acute warning by briefly and sharply
apply ing the brakes .
- If you do not react to the acute warning, brak­
ing guard can brake with increas ing force with­
in the limits of the system. This reduces the ve­
hicle speed in the event of a collision.
- The system can initiate maximum braking
shortly before a collision
1 ). Full dece leration at
high speeds occurs only in vehicles with adap­
tive cruise control and side assist (pre sense plus).
- If the braking guard senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force.
- The pre sense functions also engage when a
collision is imm inent ¢
page 177.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the MMI
¢ page 86, Settings in the Infotainment sys­
tem .
A WARNING
--
Lack of attention can cause collisions, other
accidents and serious personal injuries. The
braking guard is an assist system and cannot
prevent a collision by itself . Th e driver must
always intervene. The driver is always respon­
sib le for b raking at the co rrect time.
- Always pay close attention to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
complete control whenever necessary. Al­
ways keep the safe and legal distance be­
tween your vehicle and vehicles up ahead.
- Brak ing guard works with in limits and will
not respond outside the system limits, for
example when approach ing a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­
f ic).
- Always remember that the radar sensor for
the braking guard works only within defined
~

detection and range limits that may prevent
the proper detection of other vehicles .
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving vehicles up ahead may not be
promptly detected or may not be detected
at all.
- Reflective surfaces including crash barriers
or tunnel entrances may impair the function
of the radar sensor.
@ Tips
- You can cancel the braking with increasing
force that is initiated by the system by brak­
ing yourself, by accelerating noticeably or
by swerving .

- Keep in mind that braking guard can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.

19 mph (30 km/h).
(D Vehicles that are approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change even if it is still some­
what far away. The faster a veh icle approaches ,
the sooner the display in the exterior mirror w il l
turn on.
@Vehicles traveling with you
Vehicles traveling with you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
92
are indicated by the time they enter your "blind
spot", at the latest .
@ Vehicles left behind
If you slow ly pass a vehicle that side assist has
de tected (the diffe rence in speed between the
vehicle and your vehicle is less than 9 mph or 15
km/h), the display in the exterior mirror turns on
as soon as the vehicle enters your blind spot.
The display will not turn on if you quickly pass a
vehicle that side ass ist has detected (the differ­
ence in speed between the vehicle and your vehi­
cle is greater than 9 mph or 15 km/h).
Functional limitations
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width . In certa in situations, the dis­
play in the exterior mirror may turn on even
thou gh there is no vehicle located in the area
that is crit ica l for a lane change. For example:
- if the lanes a re narrow or if your are driving on
the edge of your lane . If this is the case, the
system may have detected the vehicle in anoth­
er lane that is
not adjacent to your current lane.
- if yo u are driving through a curve. Side assist
may react to a vehicle that is one lane over
from the adjacent lane.
- if side assist reacts to other objects (such as
high or displaced guard rai ls).
- In poor weather conditions. The side assist
functions are limited.
Do not cover the radar sensors <=?
fig. 104 with
stickers, deposits, bicycle wheels or other ob­
jects, because this wi ll affect the function. For in­
format ion on cleaning, refer to <=?
page 193.
_& WARNING
-Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a driver's attention . The driver alone
is always responsible for lane changes a nd
similar driving maneuvers .
- Improper reliance on the side ass ist system
can cause collis ions and serious pe rsonal in-
-
Jury: .,,.

-Never rely only on side assist when chang­
ing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles under
all conditions- danger of accident!
- Please note that side assist indicates there
are approaching vehicles, or vehicles in your
blind spot, only after your vehicle has
reached a driving speed of at least 19 mph
(30 km/h).
- In certain situations, the system may not function or its function may be limited. For
example:
- if vehicles are approaching or being left
behind very quickly. The display may not
turn on in time.
- in poor weather conditions such as heavy
rain, snow or heavy mist.
- on very w ide lanes, in tight curves or if
there is a rise in the road surface. Vehicles
in the adjacent lane may not be detected
because they are outside of the sensor
range.

Audi drive select Drive settings
Introduction
Drive select makes it possible to experience dif­
ferent types of vehicle settings in one vehicle.
The driver can select
Comfort, Auto and Dynami c
modes in the Infotainment system to switch, for
examp le, between a sporty and a comfortab le
driving mode. In the
Individual mode, the set­
tings can be adjusted to your personal preferen­
ces. This makes it possible to combine settings
such as a sporty engine with smooth steering.
_& WARNING
-
Improper use of the Audi dr ive select can
cause collisions, other accidents and serious
personal inju ry.
Description
The follow ing systems are affected by drive se­
lect:
Engine and transmission
Depending on the mode, the eng ine and the
transmission respond quicker or in a more bal­
anced manner to accelerator pedal movements.
I n the sporty dynamic mode, the transmission
shifts at higher RPMs.
Air suspension*
The adaptive air suspension/adaptive air suspen­
sion sport*
(A ir suspension in the MMI) is an
e lectronically controlled air suspension and
damping system. They are adjusted depending
on the se lected dr iv ing mode, the driver's steer­
ing, braking and acceleration input and the road
surface, vehicle speed and load. A sporty setting
is generally used in vehicles with adaptive air sus­
pension sport*.
The vehicle clearance varies depending on these­ lected mode and the speed.
The highway setting is activated automatically
when yo u drive above 75 mph (120 km/h) for
more than 30 seconds in the
Auto or Dynamic
Audi drive select
mode. The ground clearance is increased auto­
matically if the speed drops be low 44 mph (70
km/h) for more than 120 seconds.
Steering
T he steering adapts in terms of steer ing effort
and steering ratios. Indirect stee ring that moves
easily, like the steering in com fort mode, is best
suited to long drives on a highway. In contrast,
dynamic mode provides sporty, direct steering.
T he following applies to vehicles with dynamic
steering*: the steering ratio changes based on
vehicle speed in order to maintain optimum
steering effort for the driver at all times . This
sets the steering to be less sensitive at higher
speeds in order to provide improved vehicle con­
trol. At reduced speeds, however, steering is
more direct in order to keep the steering effort as
min imal as possible when the dr iver is maneuver­
ing the vehicle. At low and average speeds, dy­
nam ic steering additionally provides more re­
sponsive stee ring performance.
Adaptive dampers*
The adapt ive dampers* use sensors to record in­
format ion regard ing stee ring movements, brak­
ing and accele ration operations by the driver,
road surface, driving speed, and load . This makes
it possible to adapt damping to the driving situa­
tion virtua lly in real time. Drive select also makes
it possible to satisfy the desire for sporty suspen­
s ion (Dynamic) and comfortable suspension
(Comfort) without giving up balanced tuning (Au­
to) .
Sport differential*
As a component of the all whee l drive system
(quattro)
c::> page 184, the Sport differentia l*
distributes the driving power to the rear axle de­
pending on the situation. The distribution of
power varies depending on the selected mode,
from balanced (comfort) to ag ile (dynamic) . The
goal is a high level of agility and ability to accel­
erate on curves. The vehicle is very responsive to
steering.

Parking systems
General information
Applies to: vehicl es with parking system plus/rear view cam­
era/peripheral cameras
Depending on your vehicle's equipment, various
parking aids will help you when parking and ma­
neuvering.
The
parking system plus assists you when park­
ing by audibly and visually indicating objects de­
tected
in front of and behind the vehicle
¢page 108.
The rear view camera shows the area behind the
vehicle in the Infotainment display. This display
assists you when you are cross or parallel parking
¢ page 109. In addition, you are assisted by the
functions from the parking system plus
¢ page 108.
The peripheral cameras assist you with parking
and maneuvering. You are aided by various cam­
e ras depending on the vehicle equipment leve l
¢page 112. In addition, you are assisted by the
functions from the parking system plus
¢page 108.
A WARNING
-Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The parking system cannot replace
the driver's attention. The driver is always
responsible for safety during parking and
for all other maneuvers.
-
-Please note that some surfaces, such as
clothing, are not detected by the system.
- Sensors and cameras have blind spots in
which people and objects cannot be detect­ ed. Be especially cautious of children and
animals.
- The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody. The park­
ing systems may become impaired as a re­
sult. Have your authorized Audi dealer or
qualified workshop check their function.
- Make sure the sensors are not covered by
stickers, deposits or any other obstructions
Parking systems
as it may impair the sensor function. For in­
formation on cleaning, refer to
¢page 193.
(D Note
-Some objects are not detected by the sys­
tem under certain circumstances:
- Objects such as barrier chains, trailer draw
bars, vertical poles or fences
- Objects above the sensors such as wall ex­ tensions
- Objects with specific surfaces or struc­
tures such as chain link fences or powder
snow.
- If you continue driving closer to a low-lying
object, it may disappear from the sensor
range . Note that you will no longer be
warned about this obstacle.
(D Tips
- The system may provide a warning even
though there are no obstacles in the cover­ age area in some situations, such as:
- certain road surfaces or for long grass.
- external ultrasonic sources e.g. from cleaning vehicles.
- heavy rain, snow or thick vehicle exhaust.
- We recommend that you practice parking in
a traffic-free location or parking lot to be­
come familiar with the system. When doing
this, there should be good light and weath­
er conditions.
- You can change the volume and pitch of the
signals as well as the display
¢page 116.
- What appears in the infotainment display is
somewhat time-delayed.
