86 Adaptive cruise control and braking guard
Adaptive cruise control
and braking guard
Introduction
Applies to vehicles: with adaptive cruise co ntrol
The adaptive cruise control system assists the
driver by regulating 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.
Audi braking guard can warn you about an im­ pending collision with a vehicle up ahead that
is slower or has slowed down and start slow­
ing your vehicle down with the brakes
<::> page 92.
Adaptive cruise control and Audi Braking
Guard have technical limitations that you
must know, so please read this section care­
fully, understand how the system works and
use them properly at all times.
General information

must never be covered by stickers, or other
things or coated with dirt, insects, snow or ice
that will interfere with the Adaptive cruise
control system and Audi braking guard . Re­
move snow with a hand brush and remove ice with a de-icing spray that does not contain
solvents.
The function of the Adaptive cruise control
system and Audi braking guard is limited un­
der some conditions.
- Objects can only be detected when they are
within sensor range
c::> page 88, fig. 88 .
-The system has a limited ability to detect
objects that are a short distance ahead, off
to the side of your vehicle or moving into
your lane from the front or moves into your
lane from the side.
- When driving through curves
r=;> page 87.
-Some kinds of vehicles are hard to detect;
for examp le motorcycles, vehicles with high
ground clearance or overhanging loads mab
be detected when it is too late or they may
not be detected at all.
- Stationary objects
c::> page 87.
A WARNING
Improper use of the adaptive cruise con­
trol can cause collisions, other accidents
and serious personal injury. -
-Never let the comfort and convenience
that adaptive cruise control and Audi
braking guard offer distract you from the
need to be alert to traffic conditions and
the need to remain in full control of your
vehicle at all times,
- Always remember that the adaptive
cru ise control and Audi braking guard
have lim its -they will not slow the vehi­
cle 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 registered by the radar sensors, vehi­
cles or obstacles that are not moving can
trigger a collision warning and if con­
firmed by the video camera, an acute col­ lision warning.
- Always remember that the adaptive
cruise control cannot detect a vehicle
that is driving towards you in your traffic
lane and that it cannot detect narrow

Audi braking guard
Description
Applies to vehicles: wit h adapt ive c ru ise control
Fig. 94 Instrument cluster: approach warn ing
Audi brak ing guard uses radar sensors and a
video camera . It is active at speeds above
about 6.2 mph (10 km/h) and also works
within system limits when adaptive cruise control is switched off.
On vehicles with aAdaptive cruise control and
Audi side assist (Audi pre sense plus), system
functions also engage when a co llision is im­
minent
¢page 188.
What can Audi braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if your own veh icle is traveling at a
h igh speed and approaching a vehicle up
ahead that is moving more slowly. Audi brak­
ing guard does not react if it cannot detect
the situation.
The system advises you of various kinds situa­ tions :
- 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 coll is ion. The ind icator
light
I i n the d isplay comes on. Take imme ­
diate action to avoid the coll is ion and in­
crease the distance to the vehicle up ahead. -
The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov­
ing much more slowly that you are or if it
brakes sharp ly. When this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharp ly . The indicator
light
I and the symbol in the disp lay will
warn you about the danger
c:> fig. 94 . You
w ill also hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, Aud i braking guard w ill
intervene by braking and the message
braking
guard intervention
w ill appear.
- If a coll is ion is imminent, the system will
first provide an
acute warning by brak ing
sharply .
- If you do not react to the acute warning, Au­
di braking guard will brake w ith increased
force in severa l stages to reduce the speed
in a possible collisio n. On ve hicles w ith
adaptive cruise contro l and Audi side assist
(Audi pre sense plus), the system can brake
with increasing force up to maximum decel­
eration shortly before a sensed collision
¢ page 188.
- If
the Audi braking g uard senses that you
are not braking hard enough when a colli­
sion is imminent, it can increase the braking
force.
Audi braking guard takes the driver's reaction
time into consideration in order to provide
timely warnings. The system reaction time de­ creases automatically in some situations, for
example when it detects accelerator pedal use
or steering input . The Audi braking guard in­
tervent ion stops in certa in situations, for ex­
amp le if you press the accelerato r pedal to
pass the vehicle moving ahead of you in your
lane.
Which functions can be controlled?
You can switch Audi braking guard and the
distance/approach warning on or off in the

Audi lane assist Lane assist
De scription
App lies to vehicles: with la ne ass ist
Lane assist helps you keep your vehicle in your
lane.
Lane assist uses a camera to detect lane boun ­
dary lines . If the system detects that your ve­
hicle is about to cross a detected lane boun­
dary line, the steering wheel
vibrates to alert
the driver . Lane assist is operable when the
line marking the lane is detected on at least
one side of the veh icle. This is ind icated by a
g reen indicator light. in the instrument
cluster.
If the system is in active standby mode and
the turn signal is activated before driving over
the bounda ry line, the warn ing does not occur
since the system allows for intentional lane
changes.
The system is designed for driv ing on free­
ways and expanded highways and thus works
only at speeds of 40 mph (65 km/h) or more.
A WARNING
- Lane assist will not keep your vehicle in
your lane . The system only warns the
driver when the vehicle is leaving the
lane . The driver is always responsible for
keeping the vehicle in the lane .
- The camera is not able to detect all lane
boundary lines and in some cases might
also detect lane structures or objects as
boundary lines . This can lead to incorrect
warnings or wa rnings tha t fail to go off
at all.
- The camera's visibility can be impaired by
vehicles ahead of you, for instance, or by
rain, snow, heavy spray o r light sh in ing
into the camera lens. Th is can cause lane
assist to fa il to detect boundary lines.

Messages in the instrument cluster
display
When the lane assist turns off automatically,
the instrument cluster indicator goes out and
one of the following messages appears on the
display:
Audi lane assist not available: Currently no
sensor vision
This message appears when the camera can
no longer function because it cannot detect
the boundary lines. This may be due to the
following:
- T he exterior side of the camera viewing win­
dow
r:!:> fig. 96 is covered with dirt or ice.
Clean this part of the windshield.
- The camera viewing window is fogged up on
the inside. In this case, wait until the fog
disappears before turning lane assist on
again.
- The system was unab le to detect boundary
lines over an extended period of time due to
road conditions (such as snow-covered
lanes). Do not turn lane assist on again until
the lines can be more easily detected.
Audi lane assist not available
A temporary malfunction is preventing lane
assist from operating. Try turning on lane as ­
sist again at a later t ime.
Audi lane assist: system fault
The system should be checked by an author­
ized Audi dealer or other qualified workshop.
(D} Tips
-Make sure that the camera v iewing win­
dow
r:!:> fig. 96 is not covered by st ickers
or similar objects.
- Always keep the camera viewing window
clean . This can usually be done by oper­
at ing the w indshield wipers.

Setting the warning point and steering
wheel vibration
App lies to vehicles: with lane ass ist
You can adjust individual settings in the MMI.
~ Select : ICARI function button> Car systems
control button > Driver assist > Audi lane
assist.
Setting the warning point Early:
With this setting, a warning is provided
before a wheel touches the detected lane
boundary line. The warning depends on the
angle in which the vehicle is approaching the
line. The distance at which the warning is giv­
en increases as the angle becomes sharper. If
you drive toward a boundary line at a very sharp angle, the warning will come just before
a wheel touches the line.
Medium: With this setting, the warning point
is adapted to the course of the road, the lane
width and the speed. You will still be warned
Audi lane assist 97
if you cross slightly over a dotted line when
driving on curves.
Late: This setting has the same properties as
medium. You will only be warned once a
wheel crosses a detected line.
Setting the steering wheel vibration
The steering wheel vibration can be set to
Low, Medium or Strong. Selecting each of the
settings will cause the steering wheel to vi­
brate so you can check the strength of the vi­
bration in that setting.
(D Tips
Your settings are automatically stored and
assigned to the remote control key being
used.
