Audi active lane assist
Description
Applies to: ve hicles wit h Aud i act ive lane ass ist
Active lane assist (lane departure warning) de­
tects lane marker lines within the limits of the
system using a camera in the windshield . If you
are approach ing a detected lane marker line and
it appears likely that you will leave the lane, the
system w ill wa rn you w it h corre ct ive steer ing .
You can overr ide th is steering at any time . If yo u
pass over a line, the steer ing whee l wi ll vibrate
lightly. In order for this warning vibration to oc ­
cur, it must first be switched on in the Infotain­
ment system. Active lane assist is ready for oper­
ation 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 (6S km/
h).
Applies to: vehicles with side assist: if you acti­
vate a turn signal when active lane assist is ready
and it classif ies a lane change as critical because
of vehicles traveling alongside you or approach­ ing you, there w ill be not iceable correct ive steer­
i ng shortly before you leave the lane . This will at­
tempt to keep your veh icle in the la ne.
Applies to: vehicles w ithout s ide ass ist : the ready
system does not warn you if you activate a turn
A ss ista nce sys te m s
signal before crossing the lane marker line. In
t h is case, it assumes that you are changing lanes
intentionally .
Applies to: vehicles wi th adap tive c ruise contro l:
there is no corrective steering or warnings if the
system recognizes a distinct passing maneuver .
If the condit ions are met, traffic jam ass ist
switches on at speeds under approximately
40 mph (65 km/h)
qpage 116.
A WARNING
=
- The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The driver is always responsible fo r 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.
- Cor rective stee ring may not occur in certain
situations, such as during heavy b raking.
- There may be cases whe re the camera does
not recognize all lane marker lines. Cor rec­
tive steering can only take place on the s ide
of the vehicle where lane marker lines are
detected.
- Other road structu res or objects could poss i­
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 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 .
- In certain s ituations where visibility is low,
the vehicle may switch from an "early" to
"late" steering correct ion.
- Under certain condit ions such as ruts in the
road, an inclined roadway or crosswinds, the
correct ive steer ing alo ne 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 for hydroplaning . Using active lane
assist under these conditions may increase
the risk of a crash.

If the system is switched on but is not ready to
provide wa rn ings, one of the following could be
the cause:
-There is no lane marker line .
-The relevant lane marker lines are not detected
(for example, markings in a construction zone
or because they are obstructed by snow, dirt,
wate r or lighting) .
-The vehicle speed is below the activation speed
of approximate ly 40 mph (65 km/h).
- The lane is too narrow or too wide .
- The curve is too narrow.
- The driver 's hands are not on the steering
wheel.
(D Tips
- Make sure the camera window ¢fig. 124 is
not covered by stickers or other objects. For
information on cleaning, see
¢ page 354.
- In certain markets: if the system is switched
on, it will switch on automatically each time
the ignition is switched on.

Fig . 128 D isplay on the exterior mirror
Side assist (lane change ass ist) helps you mon itor
your blind spot and traffic behind yo ur vehicle.
Within the limits of the system, i t warns you
about veh icles that are coming closer or that are
traveling with you within sensor range
(D
¢ fig. 12 7. If a lane change is classified as criti­
ca l, the display @in the exterior mirror turns on
¢fig. 128.
The display in the left exterior mirror provides as­
sistance when making a lane change to the left,
while the display in the right exterior mirror pro­
vides assistance when making a lane change to
the right.
Information stage
As long as you do not activate the turn signal,
side assist
informs yo u about vehicles that are

detected and classified as crit ical. The display in
the mirror turns on, but is dim .
The display remains dim in the information stage
so that your view toward the front is not distur­
bed.
Warning stage If the d isplay in a mirror blinks brightly when you
activate a turn signal, side assist is
warning you
about detected vehicles that it has classified as
critical. If this happens, check traffic by gla nc ing
in the exterior m irrors and over your shoulder
c::> .&. in General information on page 130 .
Applies to: vehicles with active lane assist : the
d isplay i n the mirror can also blink if you have not
act ivated a turn signal: if you are app roaching a
detected lane marker line and it appears you will
be leaving the lane, side assist will warn you
about detected vehicles that it ha s classified as
critical.

S id e assist functions at speeds above approxi­
mately 9 mph (15 km/h).
@ Vehicles that are approaching
In certain cases, a vehicle will be classified as
critical for a lane change even if it is still some ­
what far away . The faster a vehicle approaches,
the sooner the display in the exterior m irror will
turn on.
@ Vehicles traveling with you
Vehicles traveling with you are indicated in the
exter ior mirror if they are classified as cr itical for
a lane change . A ll vehicles detected by side assist
are ind icated by the time they enter your "blind
spot" , at the latest .
© Vehicles you are passing
If you s lowly pass a veh icle that s ide assist has
detected (the difference in speed between the
vehicle and your vehicle is less than approximate­
ly 9 mph ( 15 km/h)) , the disp lay in the exter ior
mirror turns on as soon as the vehicle en ters your
blind spot.
The display w ill not turn on if you quickly pass a
vehicle that side assist has detected (the differ­
ence in speed is greater than approximately 9
mph (15 km/h)) .
Functional limitations
T he radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In some situations, the display
in the exterior mirror may turn on even though
there is no vehicle located in the area that is criti-
cal for a lane change. For example :

Segments in the visual display
The segments in front of and behind the vehicle
q fig. 138 help you to determine the distance be­
tween your vehicle and an obstacle . The red
lines* mark the expected direction of travel ac­
cording to the steering angle. A white segment
i ndicates an identified obstacle that is outside of
the vehicl e's path. Red segments show identified
obstacles that are in your vehicle's path. As your
vehicle comes close r to the obstacle, the seg ­
ments move clos er to the vehicle. The collision
area has been reached when the next to last seg­
ment is displayed. Obstacles in the coll is ion area ,
i ncluding those outside of the vehicle's path, are
shown in red. Do not continue driving forward or
