The fo llow ing f unc tions can be t rigge red in ce r­
tain driving s it u ations:
- T ens ion ing of the safety belts (for example,
dur ing heavy b raking): the front safety belts
have reve rsible belt tensioners. If a coll is io n
does not occur, the safe ty belts loosen slightly
and are ready to trigger again.
- Clos ing the w indows and the sun roof* (for ex ­
amp le, when ove r-or unde rsteer ing) : the w in ­
dows and the sunroof * close until there is only
a small gap open .
The function of the pre sense basi c is act ivated at
a speed o f 20 mph (30 km/h) o r higher.

Audi active lane assist
Description
Applies to: veh icles with Audi active lane assist
Active lane assist detects lane marker lines with ­
in the limits of the system using a camera in the
windshield. 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
corrective steering . You can override this steering
at any time . If you pass over a line, the steer ing
wheel will v ibrate lightly. In order for this warn­
ing vibration to occur, it must first be sw itched
on in the Infotainment system. Active lane assist
is ready for operation 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 (65 km/
h).
Applies to: vehicles with s ide assist
If you activate a turn signal when active lane as­
sist is ready and it classifies a lane change as crit­
ical because of vehicles traveling alongside you or
approaching you, there will be noticeable correc-
Assistance systems
tive steering shortly before you leave the lane.
This will attempt to keep your vehicle in the lane.
Applies to: vehicles w it h out side ass ist
The system will not warn you before crossing a
lane marker line if you have activated the turn
s ignal. In this case, it assumes that you are
changing lanes intentionally.
Applies to: veh icles w it h adaptive cruise contro l
The corrective steering is targeted based on the
driving situation. In addition to the lane marker
lines , the system can also take into account other
objects such as guard rails . If they are detected in
close proximity to the vehicle, active lane assist
helps prevent the vehicle from driving too close
to them. There is also passing ass istance. The
system does not provide any corrective steering if
it detects that you are passing another vehicle.
A WARNING ~ -
-The system warns the driver that the vehicle
is leaving the lane using corrective 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 during heavy braking.
- There may be cases where the camera does
not recognize all lane marker lines. Correc­
tive steering can only take place on the side
of the vehicle where lane marker lines are
detected.
- Other road structures or objects could possi­
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 ra in,
snow, heavy spray or light shining into the
camera. This can result in active lane assist
not detecting the lane marker lines or de­
tecting them incorrectly .
95

Assistance systems
-Under certain 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/
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.

-Th ere is no lane marker line.
-The relevant lan e marker lines are not detected
(for example, markings in a construction zone
or because they are obstructed by snow, dirt,
water or lighting).
-Th e 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.

Functional limitations
The radar sensors are des igned to detect the left
and right adjacent lanes when the road lanes are
t h e norma l width. In some si tua tions, the display
in the exterior m irror may turn on even though
there is no veh icle located in the area that is criti­
ca l for a lane change. For example:
- I f the lanes are na rrow or if you a re dr iving on
the edge o f you r lane . If t his is the case, the
system may have detected a vehicle i n another
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 .
D o no t cover the radar senso rs
¢ fig. 106 wit h
stickers, deposits, bicycle wheels or other ob­
j ects, because t hey will impair the func tion. Do
not use side assist when towing a trai ler. For in­
f ormat ion on cleaning,

Ass is tance sy stem s
-If vehicles are a pproach ing 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 bl ind
spot if your vehicle is traveling at least
1 9 mph (30 km/h).
- In certai n situations, the system may not
work or its function may be limited. For ex­ amp le:
- The display may not turn on at the rig ht
time if vehicles are approaching or passing
very quick ly.
- 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
