& WARNING
-Automatic headlights are only intended
to assist the driver . They do not relieve
the driver of his responsibility to check
the headlights and to turn them on man­
ually according to the current light and
visibility conditions. For example, fog
cannot be detected by the light sensors.
So always switch on the headlights
io
under these weather conditions and
when driving in the dark.
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists. Always turn on
theheadlightssothatyoucanseeahead and so that others can see your car from
the back .
- Please observe legal regulations when
using the lighting systems described .
(D Note
The rear fog lights should only be turned
on in accordance with traffic regulation, as
the lights are bright for following traffic.
{D) Tips
- The light sensor* for automatic head­
light range control* is located in the rear
view mirror mount . You should therefore
not apply any stickers to the windshield
in this area in order to prevent malfunc­
tions or failures .
- In the event of a light sensor malfunc ­
tion, the driver is notified in the instru­
ment cluster display ~
page 22 .
-You will hear a warning tone if you open
the driver door when the exterior lights
are switched on.
- In cool or damp weather, the inside of
the headlights, turn signals and tail lights can fog over due to the tempera­
ture difference between the inside and
outside. They will clear shortly after
switching them on. This does not affect
the service life of the lighting.
Emergency flasher
The emergency flasher makes other motorists
aware that you or your vehicle are in an emer­
gency situation .

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 regu lat ing 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 helps 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
c:::> page 92.
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. 86 Front of the veh icle: sensors and video camera
The areas that conta in the radar and ultrason­
ic sensors and the v ideo camera
c:::> fig. 86
must neve r be cove red by stic kers or other ob­
jects or obstructed w ith dirt, insects, snow or
i ce that will interfere with the adaptive cruise
control system and braking guard. For infor­
mation on cleaning, refer to
c:::> page 216. 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 cond itions:
- Objects can only be de tected when they are
w ith in sensor range
c:::> fig . 89.
-The system has a limited ability to detect
objects that are a short d istance ahead, off
to the side of your vehi cle or mov ing into
your lane.
- Some kinds of ve hicles are hard to detect;
for examp le motorcycles, veh icles 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

& WARNING
A lways pay attention to traffic when adap ­
tive cruise contro l is switched on and brak­
ing g uard is active. As the dr iver, you are
still respons ible for starting and for main­
taining speed and distance to other ob­
jects. Braking guard is used to assist you .
The dr iver must a lways take action to avo id
a collis ion . The driver is a lways respons ible
fo r braking a t the co rrec t time.
- Imp roper use of adaptive cru ise control
can cause collisions, other acc idents and
serious pe rsonal in jury.
- Never let the comfort and convenience
that adaptive cruise control and braking gua rd offer d istract you from the need to
be alert to traffic condit ions and the
need to rema in in fu ll control of your ve­
h icle at a ll 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 o r disabled vehicle.
I f registered by the radar sensors,

Audi adapt ive crui se c ontrol an d bra kin g guard 8 7
vehicles or obstacles that are not moving
can trigger a collision warning and if con­
firmed by the video camera, an acute col­ lis ion warn ing.
- 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). Using the system under
these cond itions cou ld result in a co lli ­
sion .
- Switch adaptive 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
celerating to the set speed when in these
situations .
- The adapt ive cru ise control system w ill
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 traffic, adaptive cruise
control 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
ima ls, objects crossing the road o r on­
coming objects .
- The function of the radar sensors can be
affected by reflective objects such as
guard ra ils, the entra nce to a tunnel,
he avy rain or i ce.
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise cont ro l c anno t slow or
brake the veh icle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
funct ion cannot bring the veh icle to a
sudden or emergency stop under these
condit ions .
- 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 bumper, wheel housing and
underbody. That cou ld affect the adaptive
cruise control system and brak ing guard .
Have your authorized Aud i dea le r or a u­
thorized Audi Serv ice Facility check their
funct ion.

Audi braking guard
Descript ion
App lies to vehicles: with Audi adap tive cruise control
Fig. 96 Instrument cluster: approach warn ing
Braking guard uses radar sensors and a video
camera . It also functions within the limits of
the system when adapt ive 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 traveling at a
high speed and approaching a vehicle up
ahead that is moving more slowly . Brak ing
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
I in the display comes on .
- The
approach warning is given when a de­
tected veh icle 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 possible to avoid a collision
by swerving or braking sharply. Th e indicator
light
I and indicato r in the display will warn
you about the danger¢
fig. 96. You will a lso
hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, braking guard will inter-

vene by braking and the message braking
guard intervention
wi ll appear.
- If a coll is ion is imm inent, the system wi ll
fi rst prov ide an
acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking guard can brake with increas ing
force within the limits of the system . This
reduces the vehicle speed in the event of a
collision.
- The system can initiate maximum braking
short ly before a co llision
1l . Full deceleration
at high speeds occurs only in vehicles with
adaptive cruise control and side assist (pre
sense plus) .
- If the braking guard senses that you are not
braking hard enough when a collision is im­
m inent, it can increase the braking force .
- The pre sense functions also engage when a
collision is imminent¢
page 194.
Which function s can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the MMI
i=> page 93, 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 dr iver is
a lways respons ible for braking at the cor­
rect 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 necessa­
ry. Always keep the safe and legal dis­
tance between your veh icle and vehicles
up ahead.
- Braking guard works within limits and
will not respond outside the system lim­
its, for example when approaching a
stopped vehicle or stationary obstacle ..,.

Audi adaptive cru ise control and brakin g guar d 93
(end of a traffic jam or veh icle t hat has
br oken down in traffic).
- Alw ays remember that the radar sensor
for the b raking guard works only within
defined detection and ra nge limits that
may prev ent the proper det ection of oth­
er ve hicles.
- The ra dar 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 rances may impair the
function of the radar sensor.
(0 Tips
- You can cance l the braking w ith increas­
i ng fo rce that is initiated by the system
by braking yo urself, by accelerating no­
ticeab ly or by swerving.
- Brak ing guard error messages
<=> page 93.
-Keep in mind that braking guard can
brake unexpectedly. Always secure any
ca rgo or objec ts that you are transport ­
i ng to reduce t he risk of d amage o r in­
Ju ry.
