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
¢p age 92.
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 .
Have an au thorized Audi dealer o r autho rized

A WARNING
Following other vehicles too closely increases
the risk of coll isions and ser ious personal in­
jury.
- Setting short distances to the traffic ahead
reduces the t ime and distance available to
br ing your vehicle to a safe stop and makes
it even mo re necessary to pay close atten­
t ion to traffic.
- Always obey applicable traffic laws, use
good j udgment, and select a safe following
distance for the traffic, road and weather
condit ions .
@ Tips
- Di stance

F ig. 98 Instrument c luster: request for driver intervention
In certain situations, the system will request you
to take action:
- if the braking from the adaptive cruise control
system is not enough to maintain enough dis­
tance to the object ahead.
T he danger is indicated by the. indicator light
~ fig. 98. An aud io signa l will also sound.
- Press the brake pedal to slow your vehicle down.
Audi braking guard
Applies to: vehicles with Audi adaptive cruise control
Fig . 99 Instrument cluste r: approac h warning
The braking guard uses radar sensors and a v ideo
camera. It also f unctions w ith in t he lim its of the
system when adaptive cru ise control is switched
off.
What can the b raking guard d o?
When detected in time, the system can assess
dange rous situations where an object ahead
brakes sudden ly or if yo ur own vehicle is trave ling
at a high speed and approaching an object that is
II>

Assist
moving more slowly. The braking guard does not
react if it cannot detect the situation.
The system advises you of various dangerous sit­
uations:
- The
distance warning occurs if you drive too
closely to the object ahead for a long period of
time . If the object ahead brakes strongly, you
would not be able to avoid a collision. The.
indicator light appears as an indication for this.
- The
approach warning occurs when an object
ahead is traveling more slowly or brakes
strongly . When this warning occurs, it may only
be possible to avoid a collision by swerving or
braking strongly. The danger is indicated by the
• indicator light ¢
fig. 99. An aud io signa l will
also sound.
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 collision is imminent, the system will first
provide an
acute warning by braking sharply.
- If you do not react to the acute warning, the
braking guard can increase the braking force
within the limits of the system
1l. Th is reduces
the vehicle speed in the event of a co llision.
- The system can initiate complete deceleration
shortly before a collision
ll. Full deceleration at
high speeds occurs only in vehicles with adap­
tive cruise control and s ide assist (pre sense
plus).
- If the braking guard determines that you are
not braking strongly enough when there is an
impen ding collision, it can increase the braking
force .
- The pre sense functions also engage when
there is an impending collision
¢ page 137.
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 ¢

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.
(D 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
t he risk of damage or injury.

Care and cleaning
-To reduce the risk of cuts, protect yourself
from sharp metal components when was h­
ing the underbody or the inside of the wheel
housings .
- After washing the vehicle, the braking effect
may be delayed due to mo isture on the
brake rotors or ice in the winter . This in­
creases the risk of an acc ident. The bra kes
must be d ried first w ith a few careful brake
applica tions.
0 Note
- If you wash the ve hicle in an automatic car
wash, you must fold the exterior m irrors in
to reduce the risk of damage. Power fo ld ing
ex ter ior mirro rs* m ust only be folded in and
out using the power folding function.
- To reduce the risk of paint damage, do not
wash the vehicle i n dire ct sunlig ht.
- T o reduce t he risk of damage to the surface,
do not use i nsec t remov ing sponges, ki tchen
s ponges or similar items. - Matte finish painted vehicle components:
-To reduce the r isk of damage to the sur-
face, do not use polis hing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect .
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­
moved. @ For the sake of the environment
Only wash t he ve hicle in facilities spec ially de­
signed for that pu rpose. This will reduce the
r isk of dirty wate r contaminated with o il from
ente ring the sewe r system.
