Audi pre sense
Introduction
Applies to : vehicles wi th Aud i pre sense
Within the limits of the system, the pre sense
funct ions can initiate measures i n pa rtic ularly
dangerous situations to protect the vehicle pas-
sengers a nd other road use rs. ..,.
117

Ass is tan ce sys tems
-Due to the interlinking of various vehicle sys­
tems, critica l driving situations can be detected
by
pr e se nse basic and measures for preventa­
tive occupant protection are can be initiated.
- The
pre sen se fro nt system uses the data from
the adapt ive cruise control* radar sensors and
the camera to calculate the probability of a col­ lis ion. Within the limits of the system, an im­
pending collision with vehicles can be detected
i n both urban and rural speed ranges. In this
case, the system warns the dr iver visually,
acoustically and with a jerk on the brakes if nec­
essary.
If needed, it can initiate a pa rtial or fu ll
deceleration to reduce the co llision speed or to
avoid the collision under certain circumstances .
In conjunction with pre sense basic/rear, the
front safety belts are also reversibly tensioned
when needed. The pre sense front is also active
when adapt ive cruise control* is switched off.
- Pre se nse re ar contains pre sense basic func­
tions. It uses the data from the side assist" ra­
dar sensors and calculates within the limits of
the system the probab ility of a rear end coll i­
s ion with the vehicle behind you . Pre sense rear
is also active when s ide assist* is swit ched off.
- Within the limits of the system,
pre sense city
uses the camera data and ca n detect a n im­
pending coll ision with veh icles and pedest rians.
In this case, the system warns the driver vis ual­
ly, acoustically and with a jerk on the brakes if
necessary. If needed, it can initiate a fu ll decel­
eration to reduce the co llision speed or to avoid
the coll is ion under certain circumstances. In
conjunction w ith pre sense bas ic/rear, the front
safety belts are also revers ibly tensioned when
needed .
.8. WARNING
Read the general informat ion in~ .& in Gen­
eral information on page 108, ~.& in Gener­
al information on page 127.
- Certain pre sense functions switch off when
driving in reverse.
1> Th is is not availab le in some co untr ies.
118
- The p re sense f unct ions may not be availa ­
ble if there is a malfunction in the ESC sys­
tem o r the a irbag control module .
- Note that the reversible belt tensioner on
the front passenger's side deactivates when
the front passenger's airbag is deactivated.
- Switch the pre sense off when you are not
using public streets or when load ing the ve­
hicle onto a vehicle carrier, tra in, sh ip or
other type of transportat ion. This can pre­
vent an undesired intervention from the pre
sense system.
Audi pre sense basic
Description
App lies to : vehicles wi th Aud i pr e se nse basic
The pre sense basic functions are activated at a
speed of approximately 20 mph (30 km/h) or
higher.
The following functions can be triggered under
certain conditions within the limits of the sys­
tem:
- Tensioning of the safety belts (for examp le,
during heavy braking): the front safety belts
have reversib le be lt tensioners . If a collision
does not occur, the safety belts loosen slightly
and are ready to trigger aga in.
- Closing the windows and sunroof*.
-Activating the emergency flashers

Audi pre sense front
Description
Applies to: vehicles wi th Audi ada ptive c ruise con trol
Within the limits of the system, pre sense front
can warn you of impend ing collisions and init iate
the corresponding braking maneuvers or the sup- porting measures when avoid ing a coll is ion. .,.

Ass is tan ce sys tems
& 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
the r is k of damage or inju ry.

:E: ' 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
b le braking maneuver if needed. Pre sense city is
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
tions . The
early warning occurs if:
- a vehicle driving ahead brakes suddenly,
- your own vehicle approaches a significantly
slower vehicle or stationary vehicle in the direc­
tion of travel.
- a pedestrian is standing in the lane or is moving
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
Audi pre sense.
¢ page 119, fig. 115 and a warning tone will
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 pre sense. also ap­
pea rs .
The following functions are triggered in conjunc­
tion with pre sense basic/rear:
- Revers ible tensioning of the front safety belts .
- Closing the windows and sunroof*.
- Inflating the side bolste rs* in the seat backrest
and seat surface.
Assistance systems
Audi drive select*: the function is not active de­
pending on the mode selected .
A WARNING
--Pre sense city cannot overcome the laws of
physics. It is a system designed to assist and it cannot prevent a collision in every circum­
stance . The dr iver must always intervene.
The driver is always responsible for braking
at the correct time. Do not let the increased
safety provided tempt you into taking risks.
This could increase your risk of a coll is ion.
- The system can dep loy incorrectly due to
system-specific limits.
- To reduce the r isk of an accident, please
note that the camera does not always detect
eve ry object.
- Pre sense city does not react to animals,
crossing or oncoming veh icles, objects such
as bars, railin gs or railcars, and objects that
are difficult to detect¢.&.

Side assist (lane change assist) helps you monitor
your blind spot and traffic behind your vehicle.
W ith in the limits of the system, it warns you
about vehicles that are coming close r or that are
traveling with you w ithin sensor range(!)
c>fig. 119. If a lane change is classified as criti­
cal, the disp lay@ in the exterior mirror turns on
c>fig . 120.
The display in the left exter ior mirror provides as­
sistance when making a lane change to the left,
while the disp lay 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 vehicl es that are
detected and classified as critical. The disp lay 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.
126
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 mirrors and over your shoulder
c> .&. in General information on page 127.
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 approaching a
detected lane marker line and it appears you will
be leaving the lane, side assist will warn you
about detected vehicles that it has class ified as
critical.

In certain cases, a vehicle will be classified as
critical for a lane change even if it is still some­
what far away. The faste r a veh icle approaches,
t he sooner the display in the exterio r mirror w ill
turn on.
@ Vehicles traveling with you
Vehicles traveli ng with you are ind icated in the
exte rior mi rror if they are classified as critical for
a lane change. All vehicles detected by side assist
Assistance systems
are indicated by the time they ente r your "blind
spot", at the latest.
© Vehicles you are passing
If you s low ly pass a vehi cle that side assist has
de tected (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 exterior
mirror turns on as soon as the vehicle enters your
blind spot.
T he 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 approximate ly 9
mph (15 km/h)) .
Functional limitations
The 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 veh icle located in the area that is criti­
cal for a lane change. 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 a vehicle in 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 in the same lane
or one lane over from the adjacent lane .
- If side assist reacts to other objects (such as
roadside structures like guard rails).
- In poor weather conditions. The side assist
functions are limited.
Do not cover the radar sensors
c:> fig. 122 with
stickers, deposits, bicycle wheels or other ob­
jects, because th is will impair the function . Do
not use s ide assist when towing a trai ler. For in ­
formation on cleaning, see
c:> page 354.
A WARNING
-- Always pay attention to traffic and to the
area around your vehicle . S ide assist cannot
replace a driver's attention. The driver alone
is always responsible for lane changes and
-
similar driving maneuvers . IJI,
