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.

Description
App lies to: vehicles with Audi side assist
Fig. 104 Sensor detection range
Fig. 105 D isplay on the exterio r mirro r
Side assist helps you monitor your blind spot and
traffic behind your vehicle . Within the limits of
the system, it warns you about vehicles that are
com ing closer or that are traveling with you with­
i n sensor range
(D c> fig. 104 : if a la ne change is
classified as c ritical, the display @ in the exter ior
mirror

The display in the left ex ter ior mirro r provides as­
sis tance when making a la ne change to the left,
while t he d isp lay in the rig ht exterior mirror pro­
vides assis tance when mak ing a lane change to
the right .
Information stage
As long as you do no t activate the turn signal,
side assis t
informs you about ve hicl es tha t are
detected and class ified as crit ic al. T he disp lay in
the m irror turns on, but is dim .
The display rema ins d im in the info rmat ion s tage
so that your view toward the front is not distur­ bed.
A ssi st a nce systems
Warning stage
If the display in a mirror blinks b rightly when you
activate a turn s ignal, s ide assist is
warning you
about detected vehicles that it has classified as
critical. If this happens, check traffic by glancing
in the exterior mirrors and over your shoulder
c> .&. in General information on page 100.
Applies to: vehicles with active lane assist
T he display in the mirror can also blink if you
have not activated a turn signal: if you are ap­
proaching a detected lane marker line and it ap­
pears you will be leaving the lane, side assist w ill
warn you about detected veh icles that it has clas ­
s ified as crit ical.

Fig. 107 Rear of the veh icle: pos it ion of the senso rs
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 ¢
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:
-

a co ..... N
" N ..... 0 00 <..:l ' -If vehicles are approaching or being left
behind very quickly. The display may not
turn on in time.
- In poor weather conditions such as heavy
rain, snow or heavy mist.
- On very wide lanes, in tight curves, or if
there is a rise in the road surface. Vehicles
in the adjacent lane may not be detected
because they are outside of the sensor
range.
- Audi side assist cannot detect all vehicles
under all conditions, which can increase the
risk of accidents.
- Please note that side assist only displays ap­
proaching vehicles or vehicles in your blind
spot if your vehicle is traveling at least 19 mph (30 km/h).
- In certain situations, the system may not
work or its function may be limited . For ex­
ample:
- The display may not turn on at the right
time if vehicles are approaching or passing
very quickly.
- In poor weather conditions, such as heavy
rain, snow or fog.
- In very wide lanes, in tight curves or when
there are slopes in the roadway, vehicles
in the neighboring lanes may not be de­
tected because they are outside of the
sensor range .
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can impair the system. Have
an authorized Audi dealer or authorized Audi
Service Facility check their function.
(D Tips
- If the window glass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be incor­
rect.
