_& WARNING
- Always pay attention to the traff ic around
you when the cruise control is in operat ion .
T he driver is always respo nsib le for the
speed and the distance between his or her
vehicle and other vehicles.
- For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and w hen road condit ions are
poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because th is increases the
r isk of a n accident.
- Switch the cruise control off temporar ily
when driving in turn ing lanes, h ighway exits
o r in construction zones .
- Please note that unconsciously "resting" yo ur foot on the accelerator pedal prevents
-
D rivi ng
the cruise co ntro l from bra king . This is be­
cause the d river's accele ration overr ides the
cru ise control system.
- If a brake system malfunction such as over­
heating occurs when the cruise control sys­
tem is switched on, the brak ing funct io n in
the system may be switched off . The rest of

Audi adaptive cruise
control and braking
guard
Introduction
A ppl ies to: ve hicles with Audi adaptive cruise co ntro l
The adaptive cruise contro l system assists the
driver by regulat ing vehicle speed and helping to
maintain a set distance to the vehicle ahead,
within the limits of the system.
If the system de­
tects a moving vehicle up ahead, adaptive cruise
control can brake and then accelerate your veh i­
cle. This helps to make driving 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 maneu­
vers¢
page 85.
Adaptive cruise control and braking guard have
technical limitations that you m ust know, so
please read this section carefully, understand
how the system works and use them properly at
all times.
General information
General information
App lies to: ve hicles with Audi adaptive cruise contro l
Fig. 86 Front of th e veh icle: sensors and vi deo camera
The areas that contain the radar and u ltrason ic
sensors and the video camera¢
fig. 86 must nev­
er be covered by stickers o r other objects or ob­
structed with dirt, insects, snow or ice that wi ll
interfere with the adaptive cruise control system
and braking guard. For information on cleaning, refer to
¢
page 193. The same applies for any
modifications made in the front area.
The function of the adaptive cru ise control sys­
tem and braking g uard is limited under some
conditions:
- Objects can on ly be de tected when they are
w ith in sensor range¢
page 81, fig. 89.
- The system has a limited ability to detect ob­
jects that are a short d istance ahead, off to the
side of your vehicle or mov ing into your lane .
- Some kinds of veh icles are hard to detect; for
examp le motorcycles, veh icles w ith high
gro und clea rance or overhanging loads may be
detected when it is too late o r they may not be
detected at all.
-When driving through curves

- Stat iona ry obje cts¢ page 80.
_& WARNING
A lways pay attention to traff ic when adaptive
cruise control is sw itched on and brak ing
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 act ion to avoid a collision . The
driver is always respons ible for braking at the
cor rect time.
- Improper use of adaptive cruise control can cause collisions, other accidents and ser ious
pe rsonal injury.
- Never let the comfort and conven ience that
adapt ive cr uise control and braking g ua rd
offe r dist ract you from the need to be a lert
to traffic conditions and the need to remain
in full control of your vehicle at all times,
- Always remember that the adaptive c ruise
control and braking gua rd have limits -they
will not slow the vehicle down or maintain the set distance when you drive towards an
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 reg istered by the radar sensors, vehicles
or obstacles that are not moving can trigger
a collision wa rning and if confirmed by the
video came ra, an acute co llision wa rning.

Audi adapt ive crui se con trol a nd b rakin g guar d
-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 ra in and hydroplan­
ing). Using the system under these condi·
tions co uld result in a collision.
- Switch adaptive cruise control off tempora­
rily when driving in turn ing lanes, on ex­
pressway exits or in construction zones. Th is
prevents the vehicle from accelerating to
the set speed when in these situat ions .
- The adapt ive cr uise control system will not
brake by itself if you put your foot on the ac­
celerator peda l. Doing so can override the
speed and distance regu lation.
- When approaching stat ionary 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 oncom ing
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.
- Never follow a vehicle so closely that you
cannot stop your vehicle safely. The adap·
t ive cruise control cannot slow or brake the
vehicle safely when you fo llow another veh i­
cle too close ly. Always remember that the
automatic braking function ca nnot br ing the
vehicle to a sudden o r emergency stop un­
der these conditions .
- 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 bumpe r, whee l housing and
unde rbody. That co uld affect the adaptive
cruise control system and braking guard .
Have your authorized Audi dealer or author­
ized Audi Service Facility check their function.

In curves
Applies to: vehicles with A udi adaptive cruise control
Fig. 87 Example : dr iving into a curve
When driving into a curve c:::> fig. 87 and out of a
curve, the adapt ive cruise control may react to an
object in the neighboring lane and apply the
brakes . You can prevent that by pressing the ac­
ce lerator pedal br iefly.
Stationary objects
Applies to: vehicles with Audi adaptive cruise control
Fig. 88 Example: object chang ing lanes and stat ionary ob ·
jec t
The adaptive cruise control system only reacts to
objects that are moving or that 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 vehi­
cle @.

Description
Applies to: vehicles with Audi adaptive cruise control
Fig. 89 Detectio n ra n ge
What can adaptive cruise control do?
The adaptive cruise control system uses video, ra­
dar and ultrasound . Moving vehicles ahead can
be recognized up to about 650 feet (200 m)
away .
On open roads with no traffic, adaptive cruise
control works like a regu lar cruise contro l sys­
tem. The stored speed is ma intained . When ap­
proaching a moving vehicle detected up ahead,
the adaptive cruise control system automatically
slows down to match that vehicle's speed and
then maintains the distance that the driver previ­
ously stored. As soon as the system does not de­
tect a vehicle up ahead, adaptive cruise control
accelerates back up to the stored speed.
In stop-and-go traff ic, adaptive cruise control can
brake until the vehicle stops and accelerate again
under certain conditions and if this is possible
within the system's limits and capabilities
c;, page 83 . Adaptive cru ise control will not
make an emergency stop .
Which functions can be controlled?
When you switch adaptive cruise control on, you
can set the current speed as the "control speed"
c;, page 81, Switching on and off.
When driving, you can stop cruise control
c;, page 83 or change the speed ¢ page 82 at
any time. You can also set the distance to the object ahead
and set the adapt ive cruise control driv ing pro­
gram

speeds below 20 mph (30 km/h), will auto­
matically accelerate the vehicle to 20 mph (30 km/h), which is the minimum speed
that can be set.
@ Tips
-If you switch the ignition or the adaptive
cruise control off, the set speed is erased
from the system memory.
- The electronic stabilization control (ESC)
and the anti-slip-regulation (ASR) are auto·
matically turned on when the adaptive
cruise control is turned on. Both systems
