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 action to avoid a collision. The
driver is always responsible for braking at the
correct time.
- 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 rain and hydroplan­
ing). Using the system under these condi­
tions increases the risk of an accident.
- Switch adaptive cruise control 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 adaptive cruise control system will not
brake by itself if you put your foot on the ac­
celerator pedal. Doing so can override the
speed and distance regulation.
- When approaching stationary 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 oncoming
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.
A WARNING
- Improper use of adaptive cruise control can
cause collisions, other accidents and serious
personal injury.
- Never let the comfort and convenience that
adaptive cruise control and braking guard
Assistance systems
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 cruise
control and braking guard 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 registered by the radar sensors, vehicles
or obstacles that are not moving can trigger
a collision warning and if confirmed by the
video camera, an acute collision warning.
- Never follow a vehicle so closely that you
cannot stop your vehicle safely. The adap­
tive cruise control cannot slow or brake the
vehicle safely when you follow another vehi­ cle too closely. Always remember that the
automatic braking function cannot bring the
vehicle to a sudden or emergency stop un­
der these conditions .
- To prevent unintended operation, always
switch ACC off when it is not being used .
@ Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and underbody . That could affect the adaptive
cruise control system and braking guard .
Have an authorized Audi dealer or authorized
Audi Service Facility check their function.

Ass is tanc e system s
What can the braking guard do?
When detected in t ime, the system can assess
dangerous situations where an object ahead
brakes suddenly or if your own vehicle is traveling
at a high speed and approaching an object that is moving more slowly. The braking guard does not
react if it cannot detect the s ituation.
The system advises you of various dangerous sit­ uations :
- T he
dista nce warning occurs if you d rive 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
app ro ach warning occurs when an object
ahead is traveling more slow ly or brakes
strongly. When th is warning occurs, it may only
be possible to avoid a co llision by swerv ing or
braking strongly . The danger is indicated by the
• ind icator light ¢ fig . 98 . An aud io signal w ill
also sound .
If you do not react early enough or at all to a dan­
ge rous situation, the braking guard suppo rts you
with a brak ing intervention .
- If a collision is imminent, the system will f irst
provide an
a cut e warn ing 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
ll . Th is reduces
the vehicle speed in the event of a collision .
- The system can init iate comp lete deceleration
shortly before a collision
ll _ Full deceleration at
high speeds occurs only in vehicles with adap­
tive cru ise control and s ide ass ist (pre sense
pl us).
- If the braking gua rd determines that you are
not brak ing strongly enough whe n there is an
im pending co llision, it can increase the bra king
force .
- T he pre sense functions also engage whe n
t h ere is an impend ing collision ¢

ment system ¢
page 93, Settings in the Info ­
tainment system .
A WARNING
Lack of attention can cause collisions, other
accidents and ser ious personal injuries . The
braking guard is an assist system and cannot
prevent a collis ion by itself . The dr iver must
a lways intervene. The d river is always respon­
sib le for braking at the co rrect t ime.
- Always pay close attention to traffic, even
when the b raking guard is sw itched on. Be
ready to intervene and be ready to take
co mplete co ntro l whenever necessa ry . Al ­
ways keep the sa fe and legal distance be ­
tween your vehicle and ve hicles up ahead .
- Br aki ng g uard wo rks w ithin limits and w ill
no t respond outside the system limits, for
examp le when approaching a stopped vehi ­
cle or stationary obstacle (end of a traffic
jam or ve hicle that has broken down in traf ­
fic).
- Always remember that the radar sensor for
the brak ing 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.
Mov ing veh icles up ahead may not be
promptly detected or may not be detected
at al l.
- Reflective surfaces including crash ba rr iers
or tunne l entra nces may impair the function
of the rada r senso r.
(D Tips
- You can cancel the braking with increas ing
force that is initiated by the system by brak­ ing yourse lf, by acce le rating not iceably or
by swerv ing.
- Keep in mind that b raking gua rd can b rake
unexpectedly. A lways secure a ny cargo or

Audi active lane assist
Description
Applies to: veh icles with 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
corrective steering . You can override this steering
at any time . If you pass over a line, the steer ing
wheel will v ibrate lightly. In order for this warn­
ing vibration to occur, it must first be sw itched
on in the Infotainment system. 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).
Applies to: vehicles with s ide assist
If you activate a turn signal 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 noticeable correc-
Assistance systems
tive steering shortly before you leave the lane.
This will attempt to keep your vehicle in the lane.
Applies to: vehicles w it h out side ass ist
The system will not warn you before crossing a
lane marker line if you have activated the turn
s ignal. In this case, it assumes that you are
changing lanes intentionally.
Applies to: veh icles w it h adaptive cruise contro l
The corrective steering is targeted based on the
driving situation. In addition 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 vehicle, active lane assist
helps prevent the vehicle from driving too close
to them. There is also passing ass istance. The
system does not provide any corrective steering if
it detects that you are passing another vehicle.
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 steering
wheel.
- Corrective steering may not occur in certain
situations, such as during heavy braking.
- There may be cases where the camera does
not recognize all lane marker lines. Correc­
tive steering can only take place on the side
of the vehicle where lane marker lines are
detected.
- Other road structures or objects could possi­
b ly be identified unintentionally 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 ra in,
snow, heavy spray or light shining into the
camera. This can result in active lane assist
not detecting the lane marker lines or de­
tecting them incorrectly .

sessing the traffic situation.
- Night vision assist can only warn about peo­
ple and wild animals located within the visu­
al range of the infrared camera. The visual
range corresponds to the image in the in­
strument cluster display.
- Night vision assist may not detect people or
wild animals and mark them if
-they are not in an upright position, for ex­
ample if they are sitting or lying down
and/or
-the silhouette in the display appears in­
complete or interrupted, for example be­
cause the person is partially covered by a
vehicle or the animal is partially covered
by tall grass. This could increase the risk
of an accident.
- Never try to swerve around animals if doing
so will endanger you or other road users, be­
cause this increases the risk of an accident.
