92 Audi adaptive cruise control and braking guard
Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise co ntrol
The adaptive cruise control system assists the
driver by regulating 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. This he lps to make driv­
ing more comfortable on long highway
stretches.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers
c:::> page 98.
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.
General information
General information
Applies to vehicles: with Audi adaptive cruise co ntrol
Fig. 103 Front of the vehicle: Position of radar senso r
The area that contains the radar sensor
c:::> fig. 103 must never be cove red by stickers
or other objects or obstructed with dirt, in­
sects, snow or i ce that will interfere with the
adaptive cruise control system and braking
guard. For information on cleaning, refer to
c:::> page 193. The same applies for any modifi­
cations made in the front area . T
he function of the adaptive cruise cont rol
system and braking guard is limited under
some condit ions:
- Objects can only be detected when they are
within sensor range
c:::>page 94, fig . 106.
-The system has a limited ability to detect
objects that are a short d istance ahead, off
to the side of your vehicle or moving into
your lane.
- Some kinds of vehicles 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

A WARNING
-
Always pay attention to traffic when adap-
tive cruise contro l is switched on and brak­
ing guard is active. As the driver, you are
still respons ible for starting and for main­
tain ing speed and distance to other ob­
jects. Braking guard is used to assist you.
The driver must always take action to avoid
a col lision. The driver is always responsible
for braking at the correct time.
- Im proper use of adaptive cruise con trol
can cause collisions, other accidents and
serio us personal injury.
- Never let the comfor t and convenience
that adaptive cruise control and braking
guard offer distract you from the need to
be alert to traffic conditions and the
need to remain in full control of your ve­
h icle at a ll times,
- Always remember that the adaptive
cru ise contro l and brak ing guard have
lim its -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.
If registered by the radar sensor, vehicles
or obsta cles that are not moving can
trigger a co llision warning and if

Audi adapt ive crui se c ontrol an d bra kin g guard 9 3
confirmed by the video camera, an acute
collision warning.
- 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 rain and
hydroplan ing). Using the system under
these conditions cou ld result in a co lli­
sion.
- Switch adaptive cruise control off tempo­ rar ily when driving in turning lanes, on
expressway exits or in cons truction
zones. This prevents the vehicle from ac­ celerating to the set speed when in these
situations.
- The adaptive cr uise control system wi ll
not brake by itse lf if you p ut 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
control will not respond and braking
guard w ill have limited function.
- The adaptive cruise control system and
braking guard do not react to people, an­
ima ls, objects crossing the road or on­
coming objects.
- The function of the radar sensor can be
affected 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
adaptive cruise cont ro l cannot slow or
brake the veh icle safely when you follow
ano ther veh icle too closely. Always re­
member that the automatic braking
function cannot bring 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 sensor can be disp laced by impacts or
damage to the bumper, whee l housing and
underbody . That could affect the adaptive cruise control
system and braking g uard.
Have your authorized Audi dea ler or au­
thorized Audi Service Facility chec k their
funct ion.
In curves
App lies to vehicles: with A ud i ada ptive c ruise contro l
F ig . 1 04 Examp le : driv ing into a curve
When driving into a curve ¢ fig. 104 and out
of a curve, the adaptive cru ise contro l may re­
act to a vehicle in the next lane and app ly the
brakes. You can override or prevent the brak­
ing by pressing the accelerator pedal briefly.
Stationary objects
Applies to vehicles: wit h Audi adapt ive cr uise contro l
F ig . 1 05 Examp le: objec t chang ing la n es and stat ion­
a ry object
The adaptive cruise control system only reacts
to objects that a re mov ing or that the system
has a lready detected as moving . For examp le,
if a ve hicl e@ , which has already been detec t­
ed by the adaptive cru ise con trol , turns or
changes lanes and another stationa ry vehicle
@ is located in front of that vehicle, the sys­
tem will not react to the stationary vehicle.

F ig . 11 3 Instrumen t cl uste r: approach warn ing
Braking guard uses a radar sensor. It also
functions within the limits of the system
when adaptive cruise cont ro l is switched off .
What can Audi braking guard do?
When detected i n time, the system ca n assess
situations when a vehicle ahead brakes sud­
denly or if your own veh icle is traveling at a
hi gh speed and approachi ng a ve hicle up
a head that is moving more slowly . Brak ing
guard does not react if i t can not detect the
situation.
The system advises you of various situations :
- The
distance warning is g iven if you are too
close to t he vehicle ahead for a long time . If
the vehicle ahead b rakes sharply, you w ill
not be ab le to avoid a c oll is io n. The indicator
li ght
I in the display comes on .
- The
approach warning is g iven when a de­
tected vehicle up ahead in yo ur lane is mov­
i ng much more slowly than you are or if it
brakes sha rply . W hen th is wa rning is given,
i t may only be possib le to avoid a collisio n

sharply a pplying the brakes.
- If you do no t re act to the acu te wa rning,
bra king g uard can brake w it hi n the lim its of
the system. This red uces the vehicle speed
in the event of a collision .
- At speeds un der 20 m ph (3 0 km/h), the sys­
tem can initiate a comp lete deceleration

-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 al l.
- Reflective surfaces includ ing crash barr i­
ers or tunnel ent ran ces may impair the
function of the radar sensor.
- You can cance l the braking that is initiat­
ed by the system by braking yourself, by
accelerating noticeab ly or by swerving.
- Bra king guard error messages

- Keep in mind that braking guard can
brake unexpectedly . Always secure any
ca rgo or objects that you are transport­
i ng to reduce the risk of d amage or in ­
ju ry.

Homelink ®
Universal remote
control
Description
Applies to vehicles: with Homelink
The HomeLink universal remote control can
be programmed with the remote control for
devices that are already present.
W ith Home Link, you can control devices such
as the garage door, security systems, house lights, etc. comfortably from the inside of you
vehicle.
Homelink makes it possible for you to replace
three d iffe rent remote controls from dev ices
in your home with one universal remote. This
feature works for most garage door and exte­
rior door motor signals. Programming the in­
div idual remote control for your remote con ­
trol takes place near the center of the radiator
grille. There is a control module attached at
this location .
A one -time programm ing of the sensor must
be performed before you are able to use sys­
tems with Home link. If the system does not
activate after performing the one-time pro­
gramm ing, check whether the system uses a
rolling code
q page 117 for vehicles without
the MMI*.
& WARNING
-
- Never use the Homelink ® transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as required by federa l safety stand­
ards. This includes any garage door open­
er model manufactured before April 1,
1982.
- A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards. Using a garage door
opener without these features increases
risk of serious injury or death. -
For safety reasons never release the
parking brake or start the engine while
anyone is standing in front of the vehicle.
- A garage door or an estate gate may
sometimes be set in motion when the
Homelink ® remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, this can overstrain motor and
damage its e lectrical components - an
overheated motor is a fire hazard!
- To avo id possib le injuries or property
damage, please always make absolutely
certain that no persons or objects are lo­
cated in the range of motion of any
equipment being operated.
