Audi adaptive cruise
control
Description
Applies to: vehicles with Audi adapt ive cruise control
F ig. 89 Detection range
The adaptive cruise control system is a combina
tion of speed and distance regulation.
It assists
the driver by both regulating the speed and
maintaining a distance to the vehicle driving
ahead, within the limits of the system .
If the sys
tem detects and object ahead, adaptive cruise
control can brake and acce lerate your vehicle.
This makes driving more comfortable both on long stretches of highway and in stop-and-go
traffic.
What can adaptive cruise control do?
The adaptive cruise contro l system uses video, ra
dar and ultrasound . Objects driving ahead can be
recognized up to 650 feet (200 m) away.
On open roads with no traffic, it functions
like a
cruise control system . The stored speed is main
tained. When approaching an object ahead, the
adaptive cruise control system automatically
brakes to match that object's speed and then
maintains t he stored distance . As soon as the
system does not detect an object ahead, adaptive
cru ise control acce lerates up to the stored speed .
In stop-and-go traffic, adaptive cru ise control can
brake until the vehicle is stat ionary and then be
g in driving aga in under certain conditions
¢page 91.
Audi braking guard can warn you about an im
pending collision and initiate braking maneuvers
¢page 93.
88
Which functions can be controlled?
When you switch adaptive cruise control on, you
can set the current speed as the "control speed"
¢ page 90, Switching on/off.
When driving, you can stop cruise control
¢page 92 or cha nge the speed ¢ page 91 at
any time.
You can also set the distance to the object mov
ing ahead and set the driving mode of the adap
tive cruis e con trol

General information
Applies to: vehicles with Audi adaptive cruise control
Fig. 90 Front of the vehicle: sensors and video camera
The areas that contain the radar and ultrasonic
senso rs and the video camera ¢
fig. 90 must not
be covered by stickers, deposits or other objects
because they can interfere with the function of
the adapt ive cruise control system and braking
guard. For information on clea ning, refer to
¢ page 231. The same applies for any modif ica
tions made in the front area.
The function of the adaptive cruise control sys
tem and braking guard is limited under some
conditions.
- Objects can only be detected when they are
with in the sensor range
¢p age 88, fig. 89.
- Th e system has a limit ed ability to detect ob
jects that are a sho rt distance ahead, off to the
side of your vehicle or moving into your lane.
- Objects that 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¢

A WARNING
Always pay attention to traffic when adapt ive
cruise control is switched on and braking
guard is active . As the dr iver, you are still re
sponsible for starting and for maintaining
speed and d istance to other objects. Braking
guard is used to assist you . The driver must
always take action to avoid a collision . The
driver is always responsib le for brak ing at the
co rrect time .
- For safety reasons, do not use adapt ive
cruise co ntro l when driv ing on ro ads w ith
many curves, when the road su rface is in
poor condit ion and/or in bad weather (s uch
as ice, fog, grave l, heavy rain and hydrop la n
ing). Using the system under these condi
t ions increases the risk of an accident.
- Switch adaptive cruise contro l 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 adapt ive cru ise control system will not
brake by itself if you put your foot on the ac
celerator pedal. Doing so can overr ide the
speed and distance regulation .
- When approaching stat ionary objects such
as stopped traffic, adapt ive cru ise control
will not respo nd and braking gua rd will have
l imited func tion .
- The adapt ive cru ise control system and
bra king g uard do not react to people, ani
mals, objects crossing the road or oncom ing
objects.
- T he function of the radar sensors can be af
fec ted by reflec tive objects s uch as guard
rai ls, the ent rance to a tunnel, heavy rain or
ice.
& WARNING
- Improper use of adaptive cruise control can cause collisions, other accidents and serious
persona l injury.
- Never let the comfort and convenience that
adaptive cruise cont rol and braking guard
A ss ist
offe r dist ract you from the need to be alert
to traffic cond itions and the need to remain
in full control of your vehicle at all times,
- Always remember that the adaptive cruise
control and braking guard have limits -they
will not slow the vehicle down or maintain
the set distance when you dr ive towa rds an
obstacle or something on or near the road
that is not moving, s uch as vehicles stopped
in a t raff ic jam, a stalled or disab led vehicle.
If r eg istered by the radar sensors, vehicles
or obsta cles that are not moving ca n trigger
a co llision wa rning and if confirmed by the
video came ra, an acute co llision wa rning .
- Never fo llow a vehicle so closely that you
cannot stop your vehicle safely . The adap
tive cruise contro l cannot slow or brake the
veh icle safely w hen you follow another vehi
cle too closely. A lways remember that the
automatic braking function cannot bring the
veh icle to a sudde n or emergency stop u n
der these conditions .
- To prevent unintended operat ion , always
sw itch ACC off when it is not being used .
(D Note
The sensors can be d isplaced by impacts or
damage to the bumper, wheel housing and
underbody. That could affect the adaptive
cruise contro l system and braking gua rd .

Audi active Lane assist
Description
Appl ies to: ve hicles w ith Audi active lane assist
Active lane assist detects lane marker lines with
in the limits of the system using a camera in the
windshield. If you are approaching a detected lane marker line and it appears likely that you
will leave the lane, the system will warn you with
correct ive steering . You can ove rride th is steer ing
at any time . If you pass over a line, the steer ing
wheel will v ibrate l ightly. In order for this warn
ing vib ration to occur, it must fi rst be sw itched
on in the Infotainment sys tem . Active lane assist
is ready for operation when the lane marker line
is detected on at least one side of the vehicle .
The system is designed for driving on express
ways and highways and therefore only activates
at speeds above approximately 40 mph (65 km/
h).
A pp lies to: ve hicles w ith s ide assist
If you activate a turn sig na l when active lane as
sist is ready and it classifies a lane change as crit
ical because of vehicles traveling alongside you or
approaching you, there will be noticeab le correc
tive steering shortly before you leave the lane.
This will attempt to keep your vehicle in the lane.
A ppl ies to: ve hicles w ithout s ide ass ist
The system will not warn you before crossing a
lane marker line if yo u have activated the tu rn
signa l. In this case, it ass umes that you are
changing lanes intentiona lly .
A ppl ies to: ve hicles with adaptive cruise co ntrol
The corrective stee ring is targeted based on the
driving situat ion . In addition to the lane marker
96
li nes, the system can a lso take into account other
objects such as guard rails. If they are detected in close prox imity to the ve hicle, active lane assist
helps prevent the vehicle from dr iving too close
to them. There is a lso pass ing ass istance. The
system does not provide any corrective steering if i t detects that you are pass ing another vehicle .
A WARNING
-The system warns the drive r that the vehicle
is leaving the lane using cor rect ive steering.
The drive r is always responsible fo r keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, but it does not drive by itse lf. Al
ways keep your hands on the steering
wheel.
- Cor rective steering m ay no t occur in certain
si tuations, such as during heavy braking.
- There may be cases where t he camera does
not recognize all lane marker lines . Correc
tive steering can only take place on the s ide
of the vehicle where lane marker lines are
detected.
- Other road structures or objects could possi
bly be identified unintent ionally as lane
marker lines. As a result, corrective steering
may be unexpected or may not occur.
- The camera view can be restricted, for ex
ample by vehicles driving ahead or by rain,
snow, heavy spray or light shining into the
camera . This can result in active lane ass ist
not detecting the lane marker lines or de
tect ing them inco rrectly .
- Under certain cond it ions such as ruts in the
road, a banked roadway or crosswinds, the
corrective steer ing alone may not be enough
to keep the vehicle in the m iddle of the lane.
- For safety reasons, act ive la ne assist must
no t be use d when there are poor road and/
or weather condi tions such as slippery
roads, fog, gravel, heavy rain, snow and the potential for hydrop laning. Using active lane
assist under these conditions may increase
the risk of a crash.

not adjacent to your current lane.
- If you are driving through a curve. Side assist
may react to a vehicle that is one lane over
from the adjacent lane.
- If side assist reacts to other objects (such as
high or displaced guard rails).
- In poor weather conditions. The side assist
functions are limited.
Do not cover the radar sensors <=>
fig. 107 with
stickers, deposits, bicycle wheels or other ob
jects, because they will impair the function. Do not use side assist when towing a trailer. For in
formation on cleaning, see <=>
page 231.
A WARNING
-Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a driver's attention. The driver alone
is always responsible for lane changes and
similar driving maneuvers.
- In some 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.
- Audi side assist cannot detect all vehicles under all conditions, which can increase the
risk of accidents.
- Please note that side assist only displays ap proaching vehicles or vehicles in your blind
spot if your vehicle is traveling at least
19 mph (30 km/h).
- In certain situations, the system may not
work or its function may be limited. For ex
ample:
- The display may not turn on at the right
time if veh ides are approaching or passing
very quickly.
