Assistance systems
-With stationary objects ¢ page 89.
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
88
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.

When detected in time, the system can assess
dangerous sit uat ions where an object a head
brakes suddenly or if your own vehicle is traveling
at a high speed and approaching an object that is
mov ing more slowly. The brak ing guard does not
react if it cannot detect the situation.
The system advises you of various dangero us sit
uations :
- T he
distan ce warning occurs if you d rive too
closely to the object ahead for a long period o f
time . If the object ahead brakes strongly, you
would not be able to avoid a collision .
The.
indicator light appears as an indication for th is.
- The
app roach wa rning occurs when an object
ahead is traveling more s low ly or brakes
strongly. When th is warning occurs, it may on ly
be poss ible to avoid a co llision by swerving or
braking strongly . The danger is indicated by the
• ind icator light ~ fig . 99 . An aud io signal w ill

If you do not react early enough or at a ll to a dan
ge rous situation, the braking guard suppo rts you
w ith a brak ing intervent ion .
- If a co llision is imminent, the system will first
provide an
ac ute 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
ll . Th is reduces
the veh icle speed in the event of a collision .
- The system can init iate comp lete decelerat ion
shortly before a collision

high speeds occurs only in vehicles with adap
t ive cru ise control and s ide ass ist (pre sense

Audi active Lane assist
Description
Appl ie s to: ve hicles w ith Audi active lane assis t
Active lane assist det ects lane mark er lines with
in the limits of the system using a came ra in the
windshie ld. If you are approaching a detected
lane marker line and it appears likely that you
w ill leave the lane , the system will warn you w ith
correct ive steer ing . You can override t his steer ing
at any t ime . If yo u pass over a line, t he s teer ing
wheel will v ib rate l igh tly. In o rder for this wa rn
ing v ib ra tion to occur, i t mus t first be sw itche d
on in the Info tainmen t sys tem . Act ive lane assist
is ready for operation when the lane marke r line
is detected on at least one side of the vehicle.
T he system is designed fo r driving on express
ways and highways and therefore only activates
at speeds above approximate ly 40 mph (65 km/
h).
A pp lies to: ve hicles w ith s ide ass ist
If yo u ac tiva te a turn signa l when active lane as
sist is ready and it classifies a lane change as crit
ical because of ve hicles traveling a longside you or
approaching you, there will be noticeab le correc-
96
tive steer ing sho rt ly befo re yo u leave the lane.
This wi ll attempt to keep your ve hicle in the lane.
App lies to: vehicles wi thout s ide assis t
The system will not warn you befo re cross ing a
l ane mar ke r li ne if you have act ivated the t urn
s ignal. In this case, it assumes that you are
c h anging lanes intentionally.
App lies to: vehicles wit h adaptive c ruise contro l
The corrective steering is targeted based on the
driv ing situation . In add ition to the lane ma rke r
li nes , the system can a lso take into account other
objects such as guard rails . If they are detected in
close prox imity to the ve hicle, act ive lane ass ist
helps p reve nt the vehicle from dr iv ing too close
to t hem. The re is a lso pass ing ass ista nce. The
system does no t provide any co rrec tive steering if
i t detects that you are pass ing anot her vehicle.
A WARNING
- The system warns the drive r that the vehicle
is leaving the lane using cor rect ive steering.
The d rive r is always respons ible fo r keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, b ut it does not d rive by itse lf. Al
ways keep your ha nds on the steering
wheel.
- Cor rective steering may not occur in certain
situations, such as d uring heavy braking .
- There may be cases where t he camera does
not recognize all la n e mar ker lines. Correc
tive steering can only take place on the s ide
of the vehicle where lane ma rker lines are
detec ted .
- Othe r road str uctures or objects could poss i
b ly be identified u nintent ionally as lane
ma rker lines. As a res ult, co rr ec tive stee rin g
m ay be u nexpec ted o r m ay n ot occur .
- The camera view ca n be res tricted, fo r ex
a mp le by ve hicles dr iving ahea d or by r ain,
snow, he avy spray or lig ht shin ing into t he
camera. This can resul t in a ctive lane ass ist
not detecting the lane ma rke r lines o r de
tect ing them inco rrectly.

malfunction corrected .
Audi active lane assist: Please take over steering
This message appears if you are not steering by
yourself . If th is is the case, active lane assist does
not switch off, but it is "not ready" to provide a
war ning. The system can help you keep the vehi-
98
cle in the lane . However, you are responsible for
driving the vehicle and must steer it yourse lf .

Side assist functions at speeds above app roxi
mately 19 mph (30 km/h).
@ Vehicles that are appro aching
In certain cases, a vehicle will be classified as
cr itical for a lane change even if it is still some
what far away. The faster a veh icle app roaches ,
the sooner the d isplay in the exterio r mirror w ill
turn on .
@ Vehicles traveling with you
Vehicles traveling with you are ind icated in the
exterior m irror if they are classified as critical for
a lane change. All vehi cles detected by side assist
100
are indicated by the time they enter your "blind
spot", at the latest .
© Vehicle s you are passing
If you slow ly pass a vehicle that s ide assist has
detected (the difference in speed between the
vehicle and your vehicle is less than 9 mph (15
km/h)), the display in the exterior mirror turns
on as soon as the vehicle enters your blind spot.
The display w ill not turn on if you quickly pass a
vehicle that side ass ist has detected (the differ
ence in speed is greater than 9 mph (15 km/h)) .
Functional limitations
The radar sensors are designed to detect the left
and rig ht adjacent lanes when the road lanes are
the norma l width. In some si tuations, the display
i n the exterior m irror may turn on even though
there is no vehicle located in the area that is criti
ca l for a lane change. For example:
- If the lanes are narrow or if you are dr iving on
the edge of you r lane . If th is is the case, the
system may have detected a vehicle in another
lane that is
not adjacent to your current lane.
- If you are d riving through a curve. Side assist
may react to a vehicle that is one lane over
from the adjacent lane .
- If side assist reacts to other objects (such as
high or disp laced guard rai ls) .
- In poor weather conditions. The side assist functions are limited .
Do no t cover the rada r senso rs ¢

- 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.
