General information
The system recognizes various dangerous situa
tions. The
early warning occurs if:
- a vehicle driving ahead brakes suddenly,
- your own vehicle approaches a s ignificantly
s lower vehicle o r stationary vehicle in the direc
tion of travel.
When this warning occurs, it may only be poss i
ble to avoid a collision by swerv ing or b raking

about the danger.
If you do not react enough or not at all to a dan
ge rous situation that was detected by the sys
tem, pre sense front provides assistance by ap
p ly ing the brakes.
If a collis ion is imminent, the system w ill first
provide an
acute warning by braking sharp ly. You
will also warned by an ind icator in the instrument
cluster display¢

l ). If pre sense front determines that you
are not braking strongly enough when a collis ion
is imminent, it can increase the braking force .
The following functions trigger in conjunc tion
with pre sense basic/rear at corresponding vehi
cle speeds :
- Reversible tensioning of the front safety belts. - Closing the windows and sunroof*.
- Inflating the side bolsters* in the seat backrest
and seat surface.
Audi dr ive select*: the reversible belt tensioner,
the closing of the windows and s unroof* as we ll
as the inflating of the side bolsters* on the seat

Evasive steering support
Evasiv e steering support helps you to steer the
vehicle around an obstacle in a critical situation.
If you avoid an obstacle after the acute warning,
then the evasive steering support assists you by applying slight steering adjustment to correct
your steering wheel angle as long as you are ac
t ively steer ing. Evasive steer ing support is availa
ble at speeds between approximately 20 mph
(30 km/h) and 90 mph (150 km/h) .
Turn assist
When starting to drive and up to speeds of maxi
mum 6 mph (10 km/h), the turn assist uses a
braking intervention to prevent your ve hicle from
colliding w ith an oncoming vehicle when turning
left or r ight (ava ilable in certa in countries). The
braking intervention causes your vehicle to stay
i n its lane . ..,.

& WARNING
-Pre sense front cannot overcome the laws of
physics . It is a system designed to assist and
it cannot prevent a collision in every circum
stance. The driver must always intervene.
T he driver is always responsib le for b raking
at the co rrect time. Do not let the increased
safety provided tempt you into taking risks.
This cou ld increase your risk of a collision.
- T he system can deploy incorrectly due to
system-specific limits.
- Please note that the sensors and the camera
do not always detect all objects or lane
markings. This increases the risk of an acci
dent.
- Pre sense front does not react to people, an
ima ls or objects that are crossing the vehi
cle's path or that are diff icu lt to detect~ .&
in General information on page 108.
-Reflective objects suc h as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the function of the radar sensors and
the system's ability to detect a collis ion risk.
0 Note
The sensors can be displaced by impacts or
damage to the bumper, whee l housing and
underbody. Pre sense front can be impa ired
by this. Have an authorized Audi dealer or au
thorized Audi Service Fac ility check their func
tion.
@ Tips
- You can cancel the braking with increasing
fo rce that is init iated by the system by brak
i ng yourself, by accelerat ing noticeably or
by swerving.
- Keep in mind that pre sense front can brake unexpectedly. Always sec ure any cargo o r
objects t hat you a re t ransport ing to reduce

Audi pre sense city
Description
Appl ies to: ve hicles with Audi pre sense c ity
W ith in the limits of the system, pre sense c ity
can warn you of impending coll is ions w ith
vehicles and pedestrians and initiate the applica

active at speeds of approximately 6 mph (10 km/ h) and higher.
A pedestrian warning can occur at speeds up to
50 mph (85 km/h), and vehicle warnings can oc
cur at speeds up to 155 mph (250 km/h). A pre
sense city braking maneuver is possible at speeds
up to SO mph (85 km/h).
Warnings
A ppl ies to: ve hicles with Audi pre sense c ity
The system recognizes various dangerous situa

early warning occurs if:
- a vehicle driving ahead brakes suddenly,
- your own vehicle approaches a significantly
slower vehicle or stationary vehicle in the direc

into the lane.
When this warning occurs, it may only be possi ble to avoid a collision by swerving or braking
strong ly. The message

warn you about the danger .
Additionally, a jerk on the brakes may occur as an
acute warning when there is an impending colli
sion. If you do not react to the acute warning, pre
sense city can brake to the point of complete de
celeration within the limits of the system. This reduces the vehicle speed in the event of a colli
sion. The message

Audi active lane assist
Description
Applies to: vehicles wit h Aud i act ive lane ass ist
Active lane ass ist (lane departure warning) de
tects lane marker lines within the limits of the
system using a camera in the w indshield .
If you
are approaching a detected lane marker line and
it appears likely that you will leave the lane, the
system wi ll warn you with corrective steering .
You can override this steering at any time . If you
pass over a line, the steering wheel will vibrate
lightly . In order for this warning vibration to oc
cur, it must f irst be sw itched on in the Infotain
ment system. Active lane assist is ready for oper
ation when the lane marker line is detected on at
l east one side of the vehicle.
The system is designed for driv ing on express
ways and highways and therefore only activates
at speeds above approximately 40 mph (65 km/
h).
Applies to: vehicles with side assist: if you acti
vate a turn s ignal when active lane assist is ready
and it classifies a lane change as critical because
of vehicles traveling alongside you or approach
ing you, there w ill be not iceable cor rect ive steer
ing short ly before you leave the lane . This will at
tempt to keep your vehicle in the lane .
Applies to: vehicles without side assist: the ready
system does not warn yo u if you activate a tu rn
signal befo re crossing the lane marker line. In
this case, it assumes that you are changing lanes
intentiona lly .
Applies to: vehicles with adaptive cruise control:
there is no corrective steering or warnings if the
system recogn izes a distinct passing maneuver.
If the conditions are met, traffic jam assist
switches on at speeds under approximately
40 mph (65 km/h)
¢ page 114.
A WARNING
- The system warns the driver that the veh icle
is leav ing the lane using corrective steer ing.
T he driver is always responsib le for keep ing
the vehicle within the lane.
A ss ista nce sys te m s
-The system can assist the driver in keeping
the vehicle in the lane, but it does not drive
by itself. Always keep your hands on the
steer ing 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 s ide
of the vehicle where lane marker lines are
detected .
- Other road structures 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 ra in,
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
tecting them incorrectly.
- I n certain situations where visibility is low,
the vehicle may switch from an "early" to
"late" steering correction .
- Under certain conditions such as r uts in the
road, an inclined roadway or crosswinds, the
corrective steer ing 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 condit ions may increase
the risk of a crash.
