Audi adaptive cruise control and braking guard
Audi adaptive cruise
control and braking
guard
Introduction
Applies to vehicles: with Audi adaptive cruise control
The adaptive cruise contro l system assists the
driver by regulating vehicle speed and helping to
maintain a set distance to the veh icle 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 vehi­
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
c::> page 90.
Adaptive cruise control and braking guard have
technical limitations that you must know, so
please read this section carefully, understand
how the system works and use them properly at
all times.
General information
General information
Applies to vehicles: with Audi adaptive cruise control
Fig. 88 Front of the ve hicle: sensors and video camera
The areas that contain the radar and ultrasonic
sensors and the video camera
c::> fig. 88 must nev­
er be covered by stickers or othe r objects or ob­
structed with dirt, insects, snow or ice that will
interfere with the adaptive cruise control system
and braking guard. For information on cleaning,
84
refer to c::> page 203. The same applies for any
modifications 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
w ithin sensor range
c::>page 86, fig. 91.
- Th e system has a limited ability to detect ob­
jects that are a short distance ahead, off to the
side of you r vehicle or moving into your lane .
- Some kinds of vehicles are hard to detect; for
example motorcycles, veh icles with high
ground clearance or overhanging loads may be
detected when it is too late or they may not be
detected at all.
- When driving through curves
c::> page 85.
-Stationary objects c::> page 85.
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 act ion to avoid a collision . The
driver is always respons ible for braking at the
correct time.
- Improper use of adaptive cruise control can cause collisions , other accidents and serious
personal injury.
- Never let the comfort and convenience that
adapt ive cru ise control and braking guard
offe r dist ract you from the need to be alert
to traffic conditions and the need to remain
in fu ll contro l of your ve hicle at all times,
- Always remember that the adaptive cruise
control and braking guard have limits -they
will no t 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, s uch as vehicles stopped
in a traff ic jam, a stalled or disab led vehicle.
If registered by the radar sensors, vehicles
or obstacles that are not moving can trigger
a co llision warning and if confirmed by the
video camera, an acute co llision warning.

the risk of collisions 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 a nd makes
it even more necessary to pay close atten­
t ion to traffic .
- Always obey applicable traff ic laws, use
good judgment, and select a safe following distance for the traffic, road and weathe r
condit io ns.

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to vehicles: w ith Audi adaptive cruise co ntro l
Fig. 98 Instrument cluster: approach warning
Braking guard uses radar sensors and a video
camera . It also functions within the limits of the
system when adaptive cruise control is switched
off .
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes suddenly
or if your own vehicle is traveling at a high speed
and approaching a vehicle up ahead that is mov­
ing more slowly . Braking guard does not react if
it cannot detect the situat ion.
The system advises you of various situations:
- 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 avo id a coll is ion. The indicator light.
in the display comes on .
- The
approach warning is given when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply .
When this warning is g iven, it may only be pos­
sible to avo id a collision by swerving or braking
sharp ly. Th e indicator light. and indicator in
the display will warn you about the danger
qfig. 98. You will also hear an acoustic signal.
If you do not react fast enough or do not react at
all to t he situation, braking guard will intervene
by braking.
l ) Thi s is not ava ilab le in some co un tri es .
90
-If a collision is imminent, the system will first
provide an
acute warning by briefly and sharply
app lying the brakes.
- If you do not react to the acute warning, brak­
ing guard can brake with increasing force with­
in the limits of the system. This reduces the ve­
hicle speed in the event of a collision.
- The system can initiate maximum braking
shortly before a co llision
1
) . Full deceleration at
high speeds occurs only in vehicles with adap­
tive cruise control and side assist (pre sense
plus) .
- If the braking guard senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force .
- The pre sense functions also engage when a
collision is imminent
qpage 184.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the MMI
q page 91, Settings in the Infotainment sys­
tem .
A WARNING
Lack of attent ion can cause collisions, other
accidents and serious personal injuries . The
b ra king guard is an assist system and cannot
prevent a collision by itself. The driver must
always intervene . The driver is always respon­
sib le for braking at the correct time .
- Always pay close atten tion to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
comp lete contro l whenever necessary. Al­
ways keep the safe and legal distance be­
tween your vehicle and vehicles up ahead.
- Braking guard works with in 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 brak ing guard works only within def ined Ill>

de tect ion and range limits t hat may prevent
the proper detection of other veh icles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving veh icles 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 funct ion
of the radar sensor.
(D Tips
- You can cancel the brak ing with increasing
force that is init iated by the system by b rak­
i ng yourself, by accelerat ing noticeab ly or
by swerving .

Audi active lane assist Lane assist
Description
Applies to vehicles: with Audi active lane assist
Active lane ass ist detects lane marker lines with­
i n the l imits of the system using a camera in the
windshie ld. 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
corrective steering. You can override this steering
at any time . If you pass over a line, the steering
wheel will vibrate lightly. In order for this warn­ ing vibration to occur, it must first be switched
on in the Infotainment system. Act ive lane assist
is operable when the lane marker line is detected
on at least one side of the vehicle.
The system is designed for driving on freeways
and expanded highways and thus works only at
speeds of 40 mph (65 km/h) or more .
Applies to vehicles with side assist* : If you acti­
vate a turn signal when active lane assist is ready
and it classifies a lane change as critical because
of vehicles traveling alongside you or approach­ing you, there w ill be not iceable correct ive steer­
i ng short ly before you leave the lane. This will at­
tempt to keep your veh icle in the lane.
Appl ies to vehicles w ithout s ide ass ist*: the sys­
tem does not warn when it is ready if you activate
the turn signa l before crossing the lane marker
line. In this case, it ass umes that you are chang ­
ing lanes intentionally.
Applies to vehicles w ith adapt ive cruise control*
or pa rking aid*: The corrective steering is ta rget­
ed based on the driving situation . In add ition to
the lane marker lines, the system can also take
into account other objects such as guard rails. If
they are detected in close proximity to the vehi­
cle, active lane assist helps prevent the vehicle
from driving too close to them. There is also passing assistance . The system does not provide
any correct ive steer ing if it detects that you are
passing another vehicle .
Audi act ive lane ass ist
A WARNING
- The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The driver is always responsible for keeping
the vehicle within the lane.
- The system can help you keep the vehicle in the lane, but it does not drive by itself . Al­
ways keep your hands on the stee ring
wheel.
- Corrective steering may not occur in certain
situations, such as du ring heavy b raking.
- There may be cases whe re the camera does
not recognize all la n e mar ker lines. Cor rec­
tive steering can only take place on the s ide
of the vehicle where lane marker lines are
detected.
- Othe r road structures or objects could poss i­
b ly be identified un inten tionally as lane
marker lines . As a result, corrective steering
may be unexpected or may not occur.
- The camera view can be rest ricted, for ex­
ample by vehicles driving ahead or by rain,
snow, heavy spray or light shining into the
camera. Th is can result in active lane ass ist
not detecting the lane marker lines or de­
tect ing them incorrectly.
- Under certain condit ions such as ruts in the
road, a banked roadway or crosswinds, the
correct ive steer ing alone may not be enough
to keep the vehicle in the middle of the lane .
- For safety reasons, act ive lane assist must
not be used when there are poor road and/
or weather conditions such as slippery
roads, fog, gravel, heavy rain, snow and the potential fo r hydrop laning. Using active lane
assis t under these condit ions may i ncrease
the risk of a crash .
