Audi adaptive cruise
control and braking
guard
Introduction
App lies to veh icles: w ith Audi adaptive cruise co ntrol
The adaptive cruise control system assists the
d river by regu lating veh icle speed and he lp ing 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 vehi ­
cle. This helps to make driving more comfortable
on long highway stretches.
The braking guard system can warn you about an impending collision and initiate brak ing maneu­
vers
c> page 96.
Adapt ive cruise control and braking guard have
technical limitations that you must know, so p lease read this section carefully, understand
how the system works and use them properly at
all times.

The function of the adaptive cruise contro l sys­
tem and braking guard is limited under some
cond it ions:
- Objects can on ly be detected when they are
within sensor range
,=;, page 92, fig. 106.
- T he system has a limi ted ability to detect ob­
jects that are a short d istance ahead, off to the
side of your vehicle or moving into your lane.
- Some k inds of veh icles are hard to detect; for
example motorcycles, vehicles with high
ground clearance or overhanging toads may be
detected when it is too late or they may not be
detected at all.
- When driving through curves
c::> page 91 .
- Stationary objects c::> page 91.
& WARNING
-Always pay attention to traffic when adaptive
cruise control is switched on and braking
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
a lways take action to avo id a collis ion. The
driver is always responsible for braking at the
correct t ime.
- I mprope r use of adaptive cru ise con tro l can
cause collisions, o ther accidents and serious
personal injury.
- Never let the comfort and conven ience that
adapt ive cr uise control and brak ing guard
offer distrac t you from the need to be alert
to traffic cond it ions and the need to remain
in fu ll control of your vehicle at all times,
- Always remember that the adaptive cruise
contro l and brak ing guard have limits - they
will not slow the vehicle down or maintain
the set distance when you dr ive towards an
obstacle or something on or near the road
that is not moving, such as vehicles stopped in a traff ic jam, a stalled or disab led vehicle.
If registered by the radar sensor, vehicles or
obstacles that are not moving can trigge r a
co llision warning and if confirmed by the
video camera, a n acute collision warning.

Audi adapt ive crui se cont rol and bra king gu ard
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condit ion and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan­
ing) . Us ing the system under these condi­
tions co uld resu lt in a collision.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from acce lerating to
the set speed when in these situations.
- T he adapt ive cruise con trol system w ill not
brake by itself if you put your foot on the ac­
celerator pedal. Do ing so can override the
speed and distance regulation.
- When approaching stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking guard will have
limited function .
- The adaptive cruise control system and brak­
ing guard do not react to people, anima ls,
objects cross ing the road or oncoming ob­
jects.
- The function of the radar sensor can be af­
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.
- Never follow a ve hicle so closely that you
cannot stop your vehicle safely. The adap­
t ive cr uise control cannot s low or brake the
vehicle safely when you fo llow another veh i­
cl e too close ly. Always remembe r that the
au tom atic b ra ki ng function cannot bring the
vehicle to a su dden or emergency stop un­
der these conditions.
- T o prevent unin tended operation, always
swit ch ACC
off when i t is not be ing used .
(D Note
The sensor can be disp laced by impacts o r
damage to the bumper, whee l housing and
underbody. That could affect the adaptive
cru ise cont ro l system and braking guard. Have

T he adaptive cruise control system only reacts to
objects that are moving or that the system has
already detected as moving. For example, if a ve­
hicle @, which has already been detected by the
adaptive cruise control, turns or changes lanes
and another stationary veh icle @ is located in
front of that ve hicle, the system will not react to

What can Audi adaptive cruise control do?
The adaptive cruise control works in conjunction
with a radar sensor instal led in the front of the
vehicle
¢ page 90, fig. 103, which is subject to
designated system limits¢
page 92. Stationary
objects are disregarded.
On open roads w ith no traff ic, adaptive cruise
control works like a regula r cruise control system.
The stored speed is mainta ined . When approach­
ing a moving vehicle detected up ahead, the
adaptive cruise control system automatically
slows down to match that vehicle's spe ed and
then maintains the distance that the d river previ ­
ously stored. A s soon as the system does not de­
t ec t a vehicle up ahead, adap tive cruise control
accelerates back up to the stored speed .
Which functions can be controlled?
When you switch adaptive cruise control on, you
can set the current speed as the "control speed"
¢ page 92 , Swit ch ing on and off.
When driving, you can stop cruise control
¢
pag e 94 or change the speed ¢ page 93 at
any time.
You can a lso set the distance to the object ahead

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to veh icles: w ith Audi adaptive cruise co ntrol
Fig. 113 Instrument cluster : approach warn ing
Braking guard uses a radar sensor. It also func­
tions within the limits of the system when adap­
tive cruise control is switched off.
What can Audi braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes suddenly
or if your own vehicle 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 situation .
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. The indicator light.
in the display 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 given, it may only be pos­
s ib le to avoid a collision by swerving or braking
sharply. The indicator light . and indicato r in
the display will wa rn you about the danger
¢ fig. 113 . 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 and the message
braking guard inter­
vention
will appear.
ll Thi s is not available in so me c oun tries.
96
- If a co llision is imminent, the system wi ll first
provide an
acute warning by br iefly and sharply
app ly in g the brakes.
- If you do not react to the acute warning, brak­
ing guard can brake within the limits of the sys­
tem. This reduces the vehicle speed in the event
of a collision.
- At speeds under 20 mph (30 km/h), the system
can initiate a complete deceleration shortly be­
fore a collisionl l_
-If the braking guard senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the radio or MMI
¢page
97, Settings in the radio/MM!.
A WARNING
Lack of attent ion can cause collisions, other
accidents and ser ious personal injuries. The
braking guard is an assist system and cannot
prevent a coll is ion by itself. The dr iver must
always intervene. The driver is always respon­
sib le for braking at the correct time.
- Always pay close attent ion to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take com­
plete control whenever necessary. Always
keep the safe and legal distance between
your vehicle and vehicles up ahead.
- Braking guard works within limits and will
not respond outside the system limits, for
examp le when approaching a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­
fic).
- Always remember that the radar sensor for
the braking guard works only w ith in 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

Functional limitations
The radar senso rs are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In certain situations , the dis­
play in the exterior mirror may turn on even
though there is no vehicle located in the area that
i s cr itical for a lane change. For example:
- if the lanes are narrow or if your are dr iving on
the edge of your lane. If thi s 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 c urve . 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 disp laced guard rails).
- In poor weather conditions . The side assist
functions are limited.
Do not cover the radar senso rs
q fig. 117 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will affect the function . Do not
use side assist when towing a trailer. For infor ­
mation on cleaning, refer to
q page 184.
A WARNING
- Always pay attention to traffic and to the
area around your veh icle. S ide ass ist cannot

-Improper reliance on the side assist system
can cause collisions and serious personal 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.
- Sid e assist cannot detect a ll 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 m ist .
- on very wide 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 Driving settings
Introduction
App lies to vehicles: with Audi drive select
Drive select provides the possibi lity to experience
d ifferent types of vehicle settings in one vehicle.
F or instance, using the three
Comfort, Auto and
Dynamic modes, the driver can switch from a
sporty to a comfortable driving mode with the
press of a button.
Addit ionally, in vehicles with
MM I*, the vehicle
setup for
Individual* mode can be customized by
you. This makes it possib le to combine settings
such as a sporty engine tuning with comfortab le
steering .
A WARNING
-
Improper use of the Audi drive select can
cause collisions, other acc idents and serious
personal injury.
Description
App lies to vehicles: with Audi drive select
The vehicle setup in each mode depends on the
veh icle's featu res . However, the engine, automat­
ic transmission and steering are always involved.
Engine and automatic transmission
Depending on the mode, the engine and the au­
tomatic transmission respond quicker or in a
more balanced manner to accelerator pedal
movements. In the sporty dynamic mode, the au­
tomatic transmission shifts at higher RPMs .
Steering
The steering adapts in terms of steering effort
and steering ratios. Ind irect steer ing that moves
eas ily, like the steering in comfort mode, is best
suited to long drives on a highway. In contrast,
dynamic mode provides sporty, direct stee ring.
The follow ing applies to vehicles with dynam ic
steer ing*: the steering ratio changes based on ve­
hicle speed in order to maintain optimum steer­
ing effort for the dr iver at all times. This sets the
steer ing to be less sensitive at higher speeds in
Audi drive select
order to provide improved vehicle control. At re­
duced speeds, however, steering is more direct in
order to keep the steering effort as m inima l as
possib le when the driver is maneuvering the vehi­
cle. At low and average speeds, dynamic steering
additionally provides more responsive steering performance.
Adaptive dampers*
The adaptive dampers* use sensors to record in­
formation regarding steering movements, brak­ing and acceleration operations by the driver,
road surface, driving speed, and load. This makes
i t possible to adapt damping to the driving situa­
t ion virtually in real t ime . Drive select also makes
it possible to sat isfy the desire for sporty suspen­
s ion (Dynamic) and comfortab le suspension
(Comfort) without giving up ba lanced tuning (Au­
to) .
Sport differential*
As a component of the all whee l dr ive system
(quattro)
~ page 174, the sport differential* dis­
tributes the driving power to the rear axle de­
pending on the situation. The dist ribution of
power varies depending on the mode selected.
The goal is a high level of agility and ability to ac­
ce lerate on curves. The vehicle is very responsive
to steering.
Audi adaptive cruise control*
T he behavior when accelerating can be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner.
Engine sound*
The sound of the engine is adapted to the select ­
ed mode and ranges from subtle to sporty.
(D Tips
- In some models, the maximum vehicle
speed can only be reached in the
Auto and
Dynamic modes.
- For vehicles with an automatic transmis-
sion, selecting the
Dynamic mode results in ..,.
