a co .... N
" N .... 0 00 \.J ' What can the braking guard do?
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
also sound .
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
l l. Full deceleration at
high speeds occurs only in vehicles with adap­
t ive cru ise control and s ide ass ist (pre sense
plus).
- If the braking gua rd determines that you are
not brak ing st rongly eno ugh whe n there is an
i mpending co llision, i t can increase the brak ing
fo rce .
- T he pre se nse functions also engage whe n
the re is an impend ing
collision ~ page 95.

A WARNING
--
Lack of attention can cause collisions, other
accidents and ser ious personal inj uries. The
braking guard is a n assist system and cannot
pr event a collision by itself . T he dr iver m ust
a lways inte rvene . The d river is always respon­
s ib le for b raking at the co rrect t ime.
- Always pay close atten tion to traffic, even
when the b raking gua rd is switched on. Be
ready to in tervene and be rea dy to take
comp le te co ntro l wheneve r ne cess ary. A l­
ways keep the sa fe and legal distance be ­
tween your vehi cle a nd ve hicl es up ahead .
- B raki ng g uard works w it hi n limi ts a nd will
not respond o uts ide the system limits, fo r
examp le when approach ing a stopped veh i­
cle or stationary obstacle (end of a traff ic
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
detection and range limits that may prevent
the proper detect ion of other vehicles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Mov ing vehicles up ahead may not be
promptly de tected or may no t be detected
at a ll.
- Reflective surfaces includi ng crash ba rriers
or tunne l entra nces may impair the function
of t he ra da r se nso r.
(D Tips
- You can cancel the braking with increas ing
force tha t is initiated by t he sys tem by brak­
ing yourse lf, by acce le ra ting not iceably or
by swe rving.
- Keep in mind that b raking gua rd can b rake
unexpectedly. A lways secure a ny cargo or

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.

0 00 <..:l ' -Under certa in conditions such as ruts in the
road, a banked roadway or crosswinds, the
corrective steering alone may not be enough
to keep the vehicle in the middle of the lane.
- For safety reasons , active lane assist must
not be used when there are poor road and/
o r weather conditions such as slippery
roads, fog, gravel, heavy ra in, snow and the
potent ial for hydroplaning. Using active lane
assist unde r th ese conditions may increase
the risk of a c rash .

@ 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

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 ¢
fig. 107 w it h
stickers, deposi ts, b icycle wheels or other ob­
jects, because they will impair the function . Do
not use side assist when towing a trai ler. For in­
format ion on cleaning, see
¢ page 228.
& WARNING
- Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a driver's attention . The driver alone
is always responsible for lane changes and
sim ila r driv ing maneuve rs .
- In some situations, the system may not function o r its function may be limited . For
examp le:
-
