ually activate the wipers as soon as rain
or drizzle reduces visib ility through the
windshield.
- The windshie ld must not be treated with
water-repe llent materials. They can in­
crease glare under poor visib ility condi­
t ions such as wetness, darkness, or when
the sun is low on the horizon. In addi­
t io n, they can cause the wi ndshield wip­
ers to chatter .
- Properly fu nctioning windshie ld w iper

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

-Stat ionary objec ts c:::> page 87.
& 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.

@ Vehicl es th at ar e approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change even if it is still
somewhat far away. The faster a vehicle ap­
p roaches, the sooner the display in the exteri­
or m irror will t urn on.
@ Vehicles traveling with you
Vehicles traveling w ith you are indicated in the

@ Veh icle s left behind
If you s low ly pass a vehi cle that s ide assist has
detected (the difference in speed between the
vehicle and you r vehicle is less than 9 mph or
15 km/h), the display in the exterior mirror
turns on as soon as the vehicle enters your blind spot.
The disp lay will not t urn 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).
Functi onal limitation s
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 d isp lay in the exterior mirror may
turn on even though there is no veh icle locat­
ed in the area that is 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 this is the case,
the system may have detected the vehicle in
another lane that is
not adjacent to your
current lane .
- if you a re driving through a curve. Side assist
may react to a vehicle that is one lane ove r
from the adjacent lane.
- if side assist reacts to other objects (such as
high or d isp laced guard rails) .
- In poor weather conditions. The side assist
functions are l imited .
Do not cover the radar sensors
c> fig. 104 with
stickers, depos its, bicycle wheels or other ob­
jects, because this will affect the funct ion. Do
not use s ide ass ist when towing a trailer. For
i nformation on cleaning, refer to
c> page 216 .
_&. WARNING
-Always pay attention to traffic and to t he
area around your ve hicl e. S ide assist can­
not replace a driver's attention. The driv­
er a lone is always responsible for lane
changes and similar driving mane uvers.

100 Audi side assist
-Improper reliance on the side assist sys­
tem can cause collisions and serious
personal injury:
- Never rely only 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 situations, the system may not
function or its function may be limited.
For example:
- if veh icles 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 au­
thorized Audi Service Facility check their
function.
