Audi ada pti ve c ruise contr ol and br akin g gu ard
-For safety reasons, do not use adapt ive
cruise contro l when driv ing 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
t ions could result in a collision .
- Switch adaptive cruise contro l off tempora­
rily when driving in turn ing lanes, on ex­
pressway exits or in const ruc tion zones. This
preven ts the vehicle from accelerating to
the set speed when in these situat ions .
- T he adapt ive cr uise con trol system will no t
br ake by i tself if you pu t your foot on the ac­
celerator peda l. Doing so can override the
speed and distance regulation.
- Whe n approaching stat ionary obje cts such
as stopped traffic, adapt ive cruise control
will not respo nd and braking guard will have
limited function .
- The adaptive cruise control system and
brak ing guard do not react to peop le, ani­
ma ls, objects crossing the road or oncom ing
objects.
- The function of the radar sensors can be af­
fected by reflective objects such as guard
rai ls, t he entrance to a tunnel, heavy rain or
ice.
- Never follow a veh icle so closely that you
cannot stop your vehicle safely . The adap­
t ive cr uise control cannot slow or brake the
vehicle safely when you follow another veh i­
cle too close ly. Always remember th at the
au tom atic b raking function ca nnot br ing the
vehicle to a sudden or emergency stop un­
der these conditions .
- T o preven t unintended operation, alw ays
switch AC C off when i t is not be ing used.
(D Note
The sensors can be displaced by impacts o r
damage to the bumper, whee l housing and
underbody. That co uld affect the adaptive
cru ise con trol sys tem and braking guard .
Have your a uthorized Audi dea ler or author·
ized Aud i Service Facility check their function.
In curves
Applies to vehicles: w ith Audi adapt ive cruise control
F ig. 89 Exampl e: d ri ving into a curve
When driving into a curve¢ fig. 89 and out of a
curve, the adaptive cruise control may react to an
object in the neighboring lane and app ly the
brakes . Yo u can prevent that by pressing the ac­
ce le rator peda l br iefly.
Stationary objects
Applies to vehicles : w ith Audi adaptive cruise control
Fig. 90 Exa mple : object changing la nes a nd s tatio nary ob ·
j e ct
T he 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 veh i­
cle @.

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to vehicles: w ith Audi adaptive cruise co ntro l
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 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 situat 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 avo id a coll is ion. 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 g iven, it may only be pos­
sible to avo id a collision by swerving or braking
sharp ly. Th e indicator light. and indicator in
the display will warn you about the danger
qfig. 98. You will also hear an acoustic signal.
If you do not react fast enough or do not react at
all to t he situation, braking guard will intervene
by braking.
l ) Thi s is not ava ilab le in some co un tri es .
90
-If a collision is imminent, the system will first
provide an
acute warning by briefly and sharply
app lying the brakes.
- If you do not react to the acute warning, brak­
ing guard can brake with increasing 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 co llision
1
) . Full deceleration 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 imminent
qpage 184.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the MMI
q page 91, Settings in the Infotainment sys­
tem .
A WARNING
Lack of attent ion can cause collisions, other
accidents and serious personal injuries . The
b ra king guard is an assist system and cannot
prevent a collision by itself. The driver must
always intervene . The driver is always respon­
sib le for braking at the correct time .
- Always pay close atten tion to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
comp lete contro l whenever necessary. Al­
ways keep the safe and legal distance be­
tween your vehicle and vehicles up ahead.
- Braking guard works with in limits and will
not respond outside the system limits, for
example 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 brak ing guard works only within def ined Ill>

Audi adapt ive cruis e control and braking gua rd
de tect ion and range limits t hat may prevent
the proper detection of other veh icles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving veh icles 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 funct ion
of the radar sensor.
(D Tips
- You can cancel the brak ing with increasing
force that is init iated by the system by b rak­
i ng yourself, by accelerat ing noticeab ly or
by swerving .
- Braking guard error messages ¢

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

Audi side assist
-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.
- 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 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.
(D Note
The sensors can be displaced by impacts or damage to the bumper, wheel housing and
underbody . This can affect the system . Have
your authorized Audi dealer or authorized
Audi Service Facility check their function.
(D Tips
-If the window glass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be misin­
terpreted.

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,

A WARNING
A child in a rearward-facing child seat insta l­
led on the front passenger seat will be ser i­
ously injured and can be k illed if the front air­
bag inflates - even with an Advanced Airbag
System.
- Although the Advanced A irbag System in
yo ur vehicle is designed to t urn off t he front
airbag when a rea rward-facing child re­
straint has been insta lled on the fron t pas ­
senger seat, nobody can absolutely g uaran ­
tee that deployment is impossible in a ll con­
ceivable situations that may happen during
the useful life of your vehicle.
- The inflating airbag will hit the child seat or
infant carrier w ith great force and will
smash the c hild seat and child against the
backrest, center armrest, door, or roof.
-Always install rearward-fac ing ch ild re­
straints on the rear seat.
- If you must install a rearward fac ing ch ild
seat on the front passenger seat because of
exceptiona l circumstances and the
PASSEN ­
GER A IR BAG OFF light does not come on
and stay on, immediately install the rear­
facing child seat in a rea r seat ing position
and have the airbag system inspected by
yo ur Audi dealer.
A WARNING
If, in except io nal circumst ances, you must in­
stall a forward-f acing chi ld restraint on the
front passenger's seat:
- Always ma ke sure the forward-fac ing seat
has been designed and ce rtified by its man ­
ufacturer for use on a front seat with a pas­
senger front and s ide a irbag .
- Never put the forward -facing child restraint
up against or very near the instrument pan­
el.
- Always move the passenger seat into its
rea rmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possib le, before insta lling the for­
ward-facing child restra int. The backrest
must be adjusted to an up right posit ion .
Airb ag sys tem
-Always make sure that there is noth ing on
the front passenge r seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occup ied by a person when it is
not, or to s ignal that it is occupied by some­
one w ho is heavier than the person actually
sit ting on the sea t. T he presen ce of addi­
tional ob je cts cou ld cause t he passenger
front airbag to be turned on when it should
be off, or cou ld cause the ai rbag to work in a
way that is d ifferent from the way it wou ld
have wo rked without the object on the seat.
- Make sure that the
PASSENGER AIR BAG
OFF light comes on and stays on a ll the time
whenever the ignit ion is switched on.
Advanced Airbag System components
The front passenger seat in your veh icle has a lot
of very important parts of the Advanced Airbag
System in it . These parts include the capacitive
passenger detection system, wir ing, brackets,
and more. The contro l unit m onito rs the sys tem
o n t he fro nt passenge r seat when t he igni tion is
swi tched on and turns the airbag indica tor ligh t
on when a malfunction in the one of the system
components is detected ¢
page 154. Because
the front passenger seat contains important
parts of the Advanced A irbag System, you must
take care to prevent it from being damaged.
Damage to the seat may prevent the Adva nced
Airbag System for the front passenge r seat from
doing its job in a crash.
The front Ad vanced Airbag System consists
of the following:
- Crash senso rs in the front of the veh icle tha t
measure vehicle acce le ra tion/decele ration to
p rov ide informa tion to the Advanced A irbag
System abo ut the sever ity of the cras h.
- An elect ronic contro l unit, with integ rated
cr ash sensors for front a nd side impac ts. Th e
cont rol un it "decides" whether to fi re the fron t
airbags based on the info rmation rece ived from
the crash sensors . The contro l un it also "de ­
cides" whether the safety belt pretensioners
should be activated. .,.
