Audi active lane assist
Description
App lies to veh icles: w ith Aud i active lane assis t
Active lane assist detects lane marker lines with ­
in the l imits of the system us ing a came ra in the
windshie ld. 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
corr ective steering. You can overrid e this st eering
at any time . If you pass over a line, the steering
wheel will vibrate lightly. In order for this warn­ ing vibration to occur, it must first be switched
on in the MMI. Active lane assist is operable
when the lane marker line is detected on at least
one side of the veh icle.
l) Th is fun ction is not avail able in al l countrie s.
142
The system will not warn you before crossing a
l ane marker line if you have activated the turn
s ignal. In this case, it assumes that you are
changing lanes intentionally.
The system is designed for driving on express ­
ways and highways and therefore on ly activates
at speeds above approximately 40 mph (65 km/
h).
A WARNING
-
- The system warns the driver that the vehicle
is leaving the lane using correct ive 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 du ring heavy braking.
- There may be cases where the camera does
not recognize all lane marker lines. Correc­
tive stee ring can only take place on the s ide
of the vehicle where lane marker lines are
detected.
- Other road structures or objects could poss i­
bly be identified un intent ionally 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 light shining into the
camera or by dirt on the window . This can
result in active lane assist not detecting the
lane marker lines or detect ing them incor­
rectly .
- In certain situations where visibility is low,
the vehicle may switch from "early" to "late"
corrective steer ing
1> .
- Under certain cond it ions such as ruts in the
road, an inclined roadway or crosswinds, the
corrective steer ing alone may not be enough
to keep the vehicle in the m iddle of the lane .

-For safety reasons, active lane assist must
not be used when there are poor road and/
or weather conditions such as slippery
roads, fog, gravel, heavy ra in, snow and the
potent ial for hydroplaning . Using active lane
assist under these conditions may increase
the risk of a c rash.

A ss ist
or because they are obstructed by snow, dirt,
water or lighting).

Side assist functions at speeds above approxi·
mately 19 mph (30 km/h).
@ Vehicles that are approaching
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 approaches,
the sooner the display in the exterior mirror wi ll
turn on.
@ Vehicles traveling with you
Vehicles traveling with you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
146
are indicated by the time they enter your "blind
spot", at the latest .
© Vehicles left behind
If you slow ly pass a vehicle that side assist has
de tected (the diffe rence in speed between the
vehicle and your vehicle is less than 9 mph or 15
km/h), the display in the exterior mirror turns on
as soon as the vehicle enters your blind spot.
The display will not turn on if you quickly pass a
vehicle that side ass ist has detected (the differ­
ence in speed between the vehicle and your vehi­
cle is greater than 9 mph or 15 km/h).
Functional limitations
The radar sensors are designed to detect the lef t
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 c hange. For example:
- If the lanes are narrow or if your are driving on
the edge of your lane . If this is the case, the
system may have detected the vehicle in anoth·
er lane that is
not adjacent to your current lane.
- If you are driving through a curve . Side assist
may react to a vehicle that is one lane over
from the ad jacent 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 not cover the radar sensors <=?
fig. 133 with
stickers, deposits, bicycle wheels or other ob­
jects, since this wi ll impair the function . For in·
formation on cleaning, refer to<=?
page 274.
_& WARNING
-Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a d river's attention. The driver alone
is always respo nsible for lane changes a nd
similar driving maneuvers .
- In some situations, the system may not
function or its function may be limited. For
example:
-

,....,
N
0 > co ,...., -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 certa in situations, the system may not
work or its function may be limited. For ex­
amp le:
- 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 affect the system. Have
an authorized Audi dealer or authorized Audi
Serv ice Facility check their function .
(Di Tips
-If the window glass in the driver's door or
front passenger's door has been t inted, the
display in the exterior mirror may be misin­
terpreted.
