Preventative passenger protection
Applies to: vehicles with Audi pre sense
P re sense can initiate steps to p rotect vehicle oc ­
cupants in certain dangerous situations. The
functions described are available depending on
vehicle equipment :
Pre sense basic *
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.
Dr ive se lect : th e deployment time is adapted in
Dynam ic mode.

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 .

Description
Applies to: vehicles with Audi side assist
F ig. 103 Sensor detectfon ra nge
F ig. 104 Display o n the exterio r m irror
Side assist helps you monitor your blind spo t and
traffic behind your vehicle . Within the limits of
the system, it warns you about vehicles that are
coming closer or that are traveling with you with­
i n sensor
range @<=> fig. 103 : if a lane change is
classified as critical, the display@in the exter io r
mirror
c> fig. 104 turns on.
The display in the left exter ior 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 you about vehicles that are
detected and classified as critical. The display in
the mi rror turns on, but is dim .
The display remains dim in the info rmat ion stage
so that your view toward the front is not distur­
bed.

Warning stage
If the display 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 glancing
in the exterior mirro rs and over your shoulder
c> .&. in General informa tion on page 99.
Applies to: vehicles with active lane assist
The 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 ass ist will
warn you about detected vehicles that it has clas­
s if ied as crit ical.

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 .
