Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise control
The adaptive cruise control system assists the
driver by regu lating vehicle speed and helping
to maintain a set distance to the vehicle
ahead, within the limits of the system . If the
system detects a moving vehicle up ahead,
adaptive cruise control can brake and then ac­
celerate your vehicle. Th is he lps to make driv­
ing 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
maneuvers¢
page 87.
Adaptive cruise control and braking guard
have technical limitations that you must
know, so please read this section carefully, un­
derstand how the system works and use them
properly at all times.

fig. 88
must neve r be covered by stickers or other ob­
jects or obstructed with dirt, insects, snow or
ice that will interfere with the adaptive cruise
control system and braking guard. For infor­
mation on cleaning, refer to¢
page 201. The same applies for any modifications made in
the front area.
T he function of the adaptive cru ise contro l
system and braking guard is limited under
some conditions:
- Objects can on ly be detected when they are
w ith in sensor range
¢page 83, fig. 91 .
-The system has a limited ability to detect
objects that are a shor t distance ahead,
off
t o the side of your vehicle or moving into
your lane.
- Some kinds of ve hicles are hard to detect;
for examp le motorcycles, vehicles with high
ground clearance or overhanging loads may
be detected when it is too late or they may
not be detected at all.
- When driving through curves
¢page 82 .
- Stationary objects¢ page 82.
& WARNING
Always pay attent ion to traffic when adap ­
tive cruise control is switched on and brak­ ing g uard is active. As the driver, you are
still respons ible for starting and for ma in­
taining speed and distance to other ob­
jects . Braking guard is used to assist you .
The driver must always take action to avo id
a collision. The driver is always responsible
for braking at the co rrect time.
- Improper use of adaptive cru ise control
can cause collisions, other acc idents and
serious pe rsonal in jury.
- Never let the comfort and conven ience
that adaptive cruise control and braking
guard offer d istract you from the need to
be alert to traffic condit ions and the
need to rema in in full control of your ve­
hicle at all times,
- Always remember that the adaptive
cruise control and braking guard have
limits -they will not s low the vehicle
down or maintain the set distance when
you drive towards an obstacle or some­
thing on or near the road that is not
mov ing, such as vehicles stopped in a
traffic jam, a stalled or disabled vehicle .
I f registered by the radar sensors,

82 Audi ad apti ve cruise contr ol a nd bra king gu ard
vehicles or obstacles that are not moving
can trigger a collision warning and if con­
firmed by the v ideo camera, an acute col­
lis ion warn ing .
- For safety reasons, do not use adaptive
cruise co ntrol 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) . Using the system under
these cond it ions cou ld result in a co lli ­
sion .
- Swi tch adap tive c ruise control off tempo­
rar ily when driv ing in turning lanes, on
expressway exits or in construction
zones. This prevents the vehicle from ac­
celerat ing to the set speed when in these
situations.
- The adapt ive cruise control system wi ll
not brake by itse lf if you put your foot on
the accelerator pedal. Doing so can over­
ride the speed and distance regulation .
- When approaching stationary objects such as stopped traff ic, adaptive cruise
co ntrol will not respond and braking
guard w ill have limited function.
- The adapt ive cruise control system and
braking guard do not react to people, an­
imals, objects c rossing the road or on­
coming objects .
- The function of the radar senso rs can be
affected by reflective objects such as
guard rai ls , the entrance to a tunnel,
heavy rain or ice.
- Never follow a ve hicle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise contro l canno t slow or
brake the vehicle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
function cannot br ing the vehicle to a
sudden or emergency stop under these condit ions.
- To prevent unintended operation, always switch ACC off when it is not being used. (D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That cou ld affect the adaptive
cruise control system and brak ing guard.
Have your authorized Aud i dea ler or au ­
thorized Audi Service Facility check their
funct ion .

Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 98 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 sud­
denly or if your own vehicle is t raveling at a
high speed and approaching a vehicle up
ahead that is moving 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 de­
tected vehicle up ahead in your lane is mov ­
i ng much more slowly than you are or if it
brakes sharply . When this warning is given,
it may only be possib le to avoid a collision
by swerving or braking sharply. The indicator
light. and indicator in the display will
warn you about the danger
c::> fig. 98. You
will also hear an acoustic signa l.
"' rl
"' 11
This is not ava ilable in som e coun tri es. rl
If you do not react fast enough or do not react
at all to the situation, braking guard will inter­
vene by braking.
- If a col lision is imminent, the system will
first provide an
acute warning by brief ly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking g uard can brake with increasing
force within the limits of the system . This
reduces the vehicle speed in the event of a
co llision.
- The system can initiate maximum braking
shortly before a collision
1 ) . Full deceleration
at high speeds occurs only in vehicles with
adaptive cru ise control and side assist (pre
sense plus) .
- If the braking guard senses that you are not
braking hard enough when a collision is im­
minent, it can increase the brak ing force .
- The pre sense functions also engage when a
collision is imm inent
c::> page 184 .
Which function s can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the MMI
c::> page 88, Settings in the MMI.
A WARNING
Lack of attention can cause collisions, oth­
er accidents and serious personal injuries .
The braking guard is an assist system and
cannot prevent a collision by itself. The
driver must always intervene. The driver is
always responsible for braking at the cor­
rect 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 comp lete control whenever necessa­
ry . Always keep the safe and legal dis­
tance between your vehicle and vehicles up ahead .
- Braking guard works within limits and
will not respond outside the system lim­ its, for example when approaching a

88 Audi adaptive cruise control and braking guard
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traffic).
- 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 oth­
er 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 de­
tected at all.
- Reflective surfaces including crash barri­
ers or tunnel entrances may impair the
function of the radar sensor.
({) Tips
-You can cancel the braking with increas­
ing force that is initiated by the system
by braking yourself, by accelerating no­
ticeably or by swerving.
- Braking guard error messages
¢page 88.
- Keep in mind that braking guard can
brake unexpectedly . Always secure any
cargo or objects that you are transport­
ing to reduce the risk of damage or in­
jury.

94 Audi side assist
Side assist functions at speeds above approxi­
mately 19 mph (30 km/h).
(D Vehicles that are approaching
I n certain cases, a vehicle will be classified as
cr itica l for a lane change even if it is still
somewhat far away . The faster a vehicle ap­
proaches, the sooner the display in the exteri ­
or mirror will turn on.
@ Vehicles traveling with you
Vehicles traveling with you are indicated in the
exterior m irror if they are classified as critica l
for a lane change. All vehicles detected by
side assist are indicated by the time they en­
ter your "blind spot", at the latest.
@ Vehicles left behind
If you slowly pass a vehicle that side assist has
detected (the difference in speed between the
vehicle and your vehicle is less than 9 mph or
15 km/h), the disp lay 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 assist has detected (the dif­
ference in speed between the vehicle and your
vehicle 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 certain situa­
tions, the display in the exterior mirror may
turn on even though there is no vehicle locat­
ed in the area that is critical for a lane change.
For example:
- if the lanes are 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
another lane that is
not adjacent to your
current lane.
- if you are driving through a curve. Side assist
may react to a veh icle that is one lane over
from the adjacent lane.
- if side assist reacts to other objects (such as
high or displaced guard ra ils). -
In poor weather conditions . The side assist
functions are limited.
Do not cover the rada r senso rs
~ fig. 106 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will affect the funct ion . For
information on cleaning, refer to
~ page 201.
A WARNING
-
- Always pay attention to traffic and to the
area around your vehicle. Side assist can­
not replace a driver's attention. The driv­
er alone is always responsible for lane
changes and similar dr iving maneuvers .
- Improper reliance on the side assist sys­
tem can cause coll is ions and serious per­
sonal injury:
- Never rely on ly on side assist when
changing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un­
der 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 sit uations, the system may not
function or its function may be limited.
For example:
- if vehicles are approaching or being left
behind very quickly. The disp lay may
not turn on in time.
- in poor weather conditions such as
heavy rain, snow o r heavy mist.
- 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 .

96 Audi drive select
Audi drive select Driving settings
Introduction
Audi drive select makes it possible to experi­
ence different types of vehicle settings in one
vehicle. The driver can select three
Comfort ,
Auto and Dynamic modes in the MMI to
switch between a sporty and a comfortable
driving mode.
You can also adjust the setting according to
your preferences in the
Individual mode . For
example, you can combine settings such as a
sporty engine tuning with comfortable steer­
ing.
A WARNING
Improper use of the Audi drive select can
cause collisions, other accidents and seri­
ous personal injury.
Description
The following systems are affected by drive
select:
Engine and transmission
Depending on the mode, the engine and the
transmission respond quicker or in a more bal­
anced manner to accelerator pedal move ­
ments. In the sporty dynamic mode, the
transmission shifts at higher RPMs.
Air suspension*
The adaptive air suspension/adaptive air sus­ pension sport*
(Air suspension in the MMI) is
an electronically controlled air suspension and
damping system. They are adjusted depend­
ing on the selected driving mode, the driver's
steering, braking and acceleration input and
the road surface, vehicle speed and load. A
sporty setting is generally used in vehicles
with adaptive air suspension sport*.
The vehicle clearance varies depending on the
selected mode and the speed . The
highway setting is activated automatically
when you drive above 75 mph (120 km/h) for
more than
30 seconds in the Auto or Dynamic
mode. The ground clearance is increased auto­
matically if the speed drops below
44 mph
(70 km/h) for more than 120 seconds .
Steering
The steering adapts in terms of steering effort
and steering ratios. Indirect steering that
moves easily, like the steering in comfort
mode, is best suited to long drives on a high­
way. In contrast, dynamic mode provides sporty, direct steering .
The 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
control. At reduced speeds, however, steering
is more direct in order to keep the steering ef­
fort as minimal as possible when the driver is
maneuvering the vehicle. At low and average
speeds, dynamic steering additionally pro­
vides more responsive steering performance.
Adaptive dampers*
The adaptive dampers* use sensors to record
information regarding steering movements,
braking and acceleration operations by the
driver, road surface, driving speed, and load.
This makes it possible to adapt damping to
the driving situation virtually in real time.
Drive select also makes it possible to satisfy
the desire for sporty suspension (Dynamic)
and comfortable suspension (Comfort) with­
out giving up balanced tuning (Auto) .
Sport differential*
As a component of the all wheel drive system
(quattro)
c::;; page 193, the Sport differential*
distributes the driving power to the rear axle
depending on the situation. The distribution
of power varies depending on the selected
mode, from balanced (comfort) to agile (dy­
namic). The goal is a high level of agility and

rectly as well. The parking system cannot
replace the driver's attent ion. The dr iver
is always responsible for safety during
park ing 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
wh ich peop le and objects cannot be de­
tected. Be especially cautious of children and animals.
- T he sensors can be displaced by impacts
or damage to the radiator grille, bumper ,
wheel housing and the underbody. The parking systems may become impaired
as a result. Have your authorized Audi
dealer or qualified workshop check their
function.
Par king system s 109
-Make sure the sensors are not covered by
stickers, deposits or any other obstruc­
tions as it may impair the sensor func­
tion . For information on cleaning, refer
to ¢
page 201 .
(D Note
- Some objects are not detected by the
system under certain c ircumstances :
- Objects such as ba rrie r chains, trailer
draw bars, vertical po les or fences
- Objects above the sensors such as wall
extensions
- Objects w ith specific surfaces or st ruc­
tures such as chain link fences or pow­
der snow.
- If you continue driving closer to a low-ly­
ing object, it may disappea r from the
sensor range. Note that you w ill no lon­
ger be warned about this obstacle.
@ Tips
- T he system may provide a warning even
tho ugh there are no obstacles in the cov­
erage area in some situations, such as:
- certain road surfaces or for long grass.
- externa l ultrasonic sources e.g. from
clean ing vehicles.
- heavy rain, snow or thick vehicle ex­
ha ust.
- We recommend that you practice park­
ing in a traff ic-free location or park ing
lot to become familiar w ith the system.
When doing this, there should be good light and weather cond itions .
- You can change the vo lume and pitch of
the s ignals as well as the display
