In stop-and-go traffic, adaptive cruise control can
brake until the vehicle is stationary and then be­
gin driving again under certain conditions
¢page 92.
Audi braking guard can warn you about an im­
pending collision and initiate braking maneuvers
¢page 94.
Which functions can be controlled?
When you switch adaptive cruise control on, you
can set the current speed as the "control speed"
¢ page 91, Switching on/off.
When driving, you can stop cruise control
¢
page 92 or change the speed ¢ page 92 at
anytime.
You can also set the distance to the object mov­
ing ahead and set the driving mode of the adap­
tive cruise control¢
page 93 .
General information
Applies to: veh icles with Audi adaptive cruise control
Fig. 91 Front of t he vehicle: sen sors and video came ra
The areas that contain the radar and ultrasonic
sensors and the video camera¢
fig. 91 must not
be covered by stickers, deposits or other objects
because they can interfe re with the function of
the adaptive cruise control system and braking
guard. For information on cleaning, refer to
¢
page 235. The same applies for any modifica­
tions made in the front area.
The function of the adaptive cruise control sys­
tem and brak ing guard is limited under some
conditions.
- Objects can only be detected when they are
within the sensor range¢
page 88 , fig. 90 .
Assist
- The system has a limited ability to detect ob­
jects that are a short distance ahead, off to the
side of your vehicle or moving into your lane.
- Objects th at are difficult to detect such as mo­
torcycles, vehicles with high ground clearance
or an overhanging load are detected late or not
detected at all.
- When driving through curves
¢page 90.
-With stationary objects ¢ page 90.
A WARNING ~
Always pay attention to traffic when adaptive
cruise control is switched on and braking
guard is active. As the driver, you are still re­
sponsible for starting and for maintaining
speed and distance to other objects. Braking
guard is used to assist you . The driver must
always take action to avoid a collision. The
driver is always responsible for braking at the
correct time.
- 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 condi­
tions increases the risk of an accident.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the stored speed when in these situations.
- The adaptive cruise control system will not
brake by itself if you put your foot on the ac ­
celerator pedal. Doing so can override the
speed and distance regulation.
- When approaching stationary objects such as stopped traffic, adaptive cruise control
will not respond and braking guard will have
limited function.
- The adaptive cruise control system and
braking guard do not react to people, ani­
mals, objects crossing the road or oncoming
objects.
- The function of the radar sensors can be af­
fected by reflective objects such as guard rails, the entrance to a tunnel, heavy rain or
ice.

_&. WARNING
- Improper use of adaptive cruise control can
cause collis ions, other accidents and serious
personal injury .
- Never let the comfort and convenience that
adaptive cruise control and braking guard
offer d istract you from the need to be alert
to traff ic conditions and the need to rema in
in full control of your vehicle at all times,
- Always remember that the adaptive cruise
contro l and braking guard have limits - they
will not slow the veh icle down or ma intain
the set distan ce when you drive towards a n
obstacle or something on or near the road
that is not moving, such as vehicles stopped in a traffic jam, a stalled or disabled vehicle .
If registered by the radar sensors, vehicles
or obstacles that are not moving can trigger
a collision warn ing and if confirmed by the
video camera, a n acute collision warning .
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly . The adap ­
t ive cr uise control cannot slow or brake the
vehicle safely when you fo llow another veh i­
cl e too close ly. Always remember that the
automa tic braking func tion cannot br ing the
vehicle to a sudden or emergency stop un­
der these condit ions .
- T o prevent unintended operation, always
switch ACC off when it is not being used .
(U) Note
The sensors can be displaced by impacts or
damage to the bumpe r, whee l housing and
underbody. That cou ld affect t he adaptive
cruise control system and braking guard .
Have an authorized Audi dealer or authorized
Audi Serv ice Facility check their function.

In curves
Applies to: vehicles with Audi adaptive cruise control
Fig. 92 Ex am ple: dri ving into a curv e
When dr iving into a curve c:::> fig. 92 and out of a
curve , the adapt ive cruise control may react to an
object in the neighboring lane and apply the brakes . Yo u can prevent that by pressing the ac­
ce le ra to r peda l br iefly.
Stationary objects
Applies to: vehicles with Audi adaptive cruise control
F ig . 93 Exam ple: object chang ing la nes a nd stat ion ary ob ·
jec t
The adaptive cru ise control system only reacts to
objects that are moving or t hat 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 @.

In certain situations, the system w ill request you
to take action :
- if t he braking from the adapt ive cr uise control
system is no t enough to maintai n enough dis­
tance to the object ahead.

system when adaptive cru ise control is switched
off.
What can the braking guard do ?
When detected in time, the system can assess
dange rous si tu at ions where an object ahead
brakes sudden ly or if yo ur own vehicle is trave ling
at a h igh speed and approach ing an ob ject that is
moving more slow ly. The braking guard does not
react if it cannot detect the situation.
The system advises you of var ious dange rous sit­
uations :
- The
di stan ce warning occu rs if you dr ive too
close ly to the object ahead fo r a long per iod of
time .
If the object ahead brakes strongly, you
would not be ab le to avoid a co llis ion. The .
indicator light appears as an indication for this .
- T he
appr oach w arning occurs when an object
ahead is trave ling more slowly or brakes
strongly. When this warning occurs, it may only
be possible to avoid a collis ion by swerving or
brak ing strongly . The danger is indicated by the
• indicator light
¢fig. 100 . An audio signal
w ill also so und .
If you do not react early enough or at all to a dan ­
gerous situation, the braking guard supports you
with a braking intervention .
- If a co llision is imminent, the system wi ll first
provide an
acute warning by braking sharply .
- If you do not react to th e acute warning, the
b raking guard can inc rease the braking force
w ith in the lim its of the system
1> . This reduces
the vehicle speed in the event of a coll is ion.
- T he system can in itiate complete dece leration
shortly before a collision
l) . Full deceleration at
high speeds occurs only in veh icles with adap­
tive cruise control and side assist (pre se nse
plus) .
- If the braking guard determ ines that you are
not braking s trongly enough when the re is a n
impending coll is ion, it can increas e the b raking
force.
- The p re sense funct io ns also engage w hen
there is an impending collision ~

\.J ' Which functions can be controlled?
You can switch the braking guard and the dis­
tance/approach warning on or off in the Infotain­
ment system
c::, page 95 , Settings in the Info­
tainment system.
A WARNING
Lack of attention can cause collisions, other
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 respon­
sible for braking at the correct 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 necessary. Al­
ways keep the safe and legal distance be­
tween your vehicle and vehicles up ahead.
- Braking guard works within 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 braking guard works only within defined
detection and range limits that may prevent
the proper detection of other 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 detected
at all.
- Reflective surfaces including crash barriers
or tunnel entrances may impair the function
of the radar sensor.
{!) Tips
- You can cancel the braking with increasing
force that is initiated by the system by brak­
ing yourself, by accelerating noticeably or
by swerving.
- Keep in mind that braking guard can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury .

Audi active lane assist
Description
Appl ies to: vehicles with Audi act ive lane assist
Active lane assist detects lane marker lines with­
i n the lim its of the system using a camera in the
windshield. If you are approach ing a detected
lane marker line and it appears like ly that you
will leave the lane, the system w ill warn you with
corrective steering. You can override this steering
at any time. If you pass over a line, the steering
whee l w ill vibrate lightly. In orde r fo r thi s warn­
i ng vibration to occ ur, it must first be switched
on in the Infotainment system. Active lane ass ist
is ready for operation when the lane marker line
is detected on at least one side of the vehicle.
The system is des igned for driving on express­
ways and highways and therefore on ly activates
at speeds above approximately 40 mph (65 km/
h) .
Applies to: vehicles with side assist
If you activate a turn s ignal when act ive lane as­
s ist is ready and it classifies a lane change as crit ­
ica l because of vehicles traveling a longside you or
approach ing you, there wi ll be noticeable correc­
tive steer ing shortly before you leave the lane.
This will attempt to keep your veh icle in the lane.
Applies to: vehicles without side assist
The system will not wa rn you befo re c ross ing a
l ane marke r line if you have act ivated the t urn
s ignal. In this case, it assumes that you are
changing lanes intentionally.
Applies to: vehicles with adaptive cru ise control
The corrective steer ing is targeted based on the
driv ing situation . In add it ion to the lane marke r .,.
