F ig. 106 Inst rument duster: traffic jam ass ist
In a speed range under 40 mph (65 km/h), traffic
jam ass ist can help to keep the vehicle within a
l ane calc ulated by the system. W ith in the lim its
of the system, the system contro ls the steering
automatically whe n adapt ive cr uise con trol is
sw itched on. S in ce traffic jam assist is only an as­
sist system, the dr iver must a lways keep his or
he r hands on the steer ing whee l and be ready to
steer . The driver can override the contro l at any
time by actively steering.
The system is designed for driv ing on express ­
ways and highways .

Audi pre sense
Introduction
Applies to: ve hicles w ith Audi p re se nse
W ith in the limits of the system, the pre sense
functions can in it iate measures in particularly
dangerous s ituat ions to protect the ve hicle pas ­
sengers and ot her r oad users.
- Due to the interl ink ing of various vehicle sys­
tems , crit ica l dr iv ing s ituat ions can be detected
by
pr e s ense basic and measu res fo r preventa­
t ive occ upan t protect ion are can be initiated.
- T he
pre sen se front system uses the data from
t h e adapt ive cr uise control* radar sensors and
t h e camera to calc ulate the probab ility of a col ­
lision . Within the limits of the system, an im ­
pending collision with vehicles can be detected
in both urban and rural speed ranges. In this
case, the system warns the driver visually,
acoustically and with a jerk on the brakes if nec­
essary . If needed, it can initiate a partial or fu ll
deceleration to reduce the collision speed or to
avo id the co llision unde r ce rtain c ircumstances .
In conjunct ion with p re sense basi c/rear, the
front safety belts are also revers ibly tensioned
whe n needed. The pre sense front is also act ive
when adaptive cruise control* is switched o ff.
- Pr e se nse rear con tains pre sense basic func ­
tions. It uses the data from the side assist* ra­
dar sensors and calc ulates within the limits of
the system the probability of a rear end colli ­
sion with the vehicle behind you . Pre sense rear
is also active when s ide assist* is switched off .
112
-Within the limits of the system, pre sen se cit y
uses the camera data and can detect an im ­
pending collision with vehicles and pedestrians .
In this case, the system warns the driver visual­ ly, acoustical ly and w it h a jerk on the brakes if
necessary . If needed, it ca n initiate a full dece l­
erat ion to reduce t he coll is ion speed or to avoid
the collision under certa in circumstances . In
conjunction with p re sense basi c/rear, the front
safety belts are a lso reve rsibly te nsioned whe n
needed.
& WARNING
Read the genera l information inc::>.&. in Gen ­
eral information on page 103,

al information on page 121.
(D Tips
- C erta in p re sense funct io ns sw itch off when
driving in reve rse.
- Th e pre sense f unct io ns m ay no t be ava ila ­

tem or t he airbag control module .
-Note that the reve rsib le belt tens ione r o n
the front passenger 's side deactivates when
the front passenger's airbag is deactivated.
- Switch the pre sense off when yo u are not
using public streets or when loading the ve ­
hicle onto a vehicle carrier, train, ship or
other type of transportat ion. This can pre­
vent an undesired intervention from the pre
sense system.

Fig . 108 In strumen t clu ste r: approac h warn ing
Descr iption
Within the limits of the system, pre sense front
can warn yo u of impending coll is ions and in itiate
the corresponding brak ing maneuvers or the sup­
port ing measures when avoiding a co llision .
If detected in time, the system can rank the dan ­
gerous situation as cr itica l if a vehicle driving
ahead brakes sudden ly, if you r own vehicle is ap­
proaching a s ignificantly s lower vehicle at h igh
speed or when there is an oncom ing vehicle dur­
i ng a tur ning maneuve r.
If detection is not poss ible, then pre sense front
does not react.
Warnings
The system recognizes various dange rous situa ­
tions. The
early warning occurs if:
- a vehicle d riving ahe ad brakes s udden ly,
- yo ur own vehicle approaches a s ignificant ly
s lower veh icle o r st ation ary veh icle in the dire c­
t ion of t ravel.
ll This is not availa ble in so m e co untrie s.
A ss istance systems
When this warning occurs, it may on ly be possi ­
ble to avoid a co llision by swerving o r braking
strongly . The message
Audi pre sense.
¢ fig . 108 and a wa rning tone will warn you
about the danger .
If you do not react enough or not at all to a dan­
gerous sit uat ion that was detected by the sys ­
tem, p re sense front provides assistance by ap­
ply ing the b rakes .
If a collision is imminent, the system will first
provide a n
acute warning by braking sharply . You
will a lso warned by an indicato r in the instr ument
cluster display¢
fig. 108 . If you do not react to
the acute warning, pre sense front can brake w ith
i ncreas ing fo rce wi thin the limits of the
system

even t of a co llision . At low vehicle speeds, p re
sense fron t can ini tia te a complete dece le ra tion
shor tly be fore a collision wi th a ve hicle dr iving
ahead
l)_ If pre sense front determi nes that you
are not braking strong ly enough when a co llision
is imminent, it can increase t he b raking force.
T he following fu nctions t rigge r in conjunction
with pre sense basic/rea r at co rresponding vehi ­
cle speeds:
- Reve rsible tens ion ing of the front safety bel ts.
- Clos ing the windows and sun roof* .
- Infla ting the s ide bo lsters* in the sea t backrest
and seat s urface .

Evasive steering support
Evasive s teer ing s upport helps you to steer the
vehicle a round an obstacle in a cr it ica l sit uat io n.
If you avo id an obs tacle afte r th e acute warning,

your steering whee l ang le as long as you are ac­
tively steering . Evasive steering support is availa ­
b le at speeds between approximate ly 20 mph
(30 km/h) and 90 mph (150 km/h).
Tu rn as sist
When start ing to drive and up to speeds of maxi ­
mum
6 mph (10 km/h), the turn assist uses a
braking intervention to prevent your vehicle from
colliding with an oncoming vehicle when turning
left or right (available in certain countries). The
braking in tervent ion causes your vehicle to stay
in its lane .
A WARNING
-Pre sense front cannot overcome the laws of
physics. It is a system des igned to assist a nd
i t cannot prevent a collision in every c ircum­
sta nce. The d rive r must a lways i nte rvene.
T he driver is always responsib le for b raking
at the correct time. Do not let the increased
safety provided tempt you into taking risks .
This cou ld increase your risk of a collision.
- The 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 ob jects that are crossing the veh i­
cle's path or that are diff icu lt to detect¢
&
in General information on page 103.
-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 coll is ion risk.
@ Note
The sensors can be displaced by impacts or
damage to the bumper, whee l housing and
underbody . Pre sense fro nt can be impa ired
by this. Have an autho rized Aud i dea le r or a u­
thorized A ud i Service Fac ility check the ir func­
tion.

(D Tips
- You can cancel the braking with increasing
force that is initiated by t he system by brak ­
ing yourself, by acce lerating not iceably or
by swerving.
- Keep in mind that pre sense front can brake unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury .
- Specific pre sense front functions switch

Audi pre sense city
Applies to: vehicles with Audi pre sense city
Description
Within the limits of the system, pre sense city
can warn you of impending collisions with
vehicles and pedestrians and initiate the applica­
ble 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
SO 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
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
strongly. The message
Audi pre sense.
r:=;, page 113, fig. 108 and a warning tone will
warn you about the danger .
Assistance systems
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
pears.
The following functions are triggered in conjunc­
tion with pre sense basic/rear:
- Reversible tensioning of the front safety belts.
- Closing the windows and sunroof*.
- Inflating the side bolsters* in the seat backrest
and seat surface.
Audi drive select*: the function is not active de­ pending on the mode selected.
_&. 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 driver 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 collision.
- The system can deploy incorrectly due to
system-specific limits .
- To reduce the risk of an accident, please
note that the camera does not always detect
every object.
- Pre sense city does not react to animals,
crossing or oncoming vehicles, objects such
as bars, railings or railcars, and objects that
are difficult to detect
r:=;, _& in General infor­
mation on page 103.
- In trailer mode, the braking behavior of the
trailer can be different than usual during au­
tomatic braking.

lightly. In order for this warn ing vibration to oc­
cur, it must first 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 least 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 w ith side assist: if you acti­
vate a turn s ignal when active lane ass ist is ready
and it class if ies a lane change as critical because
of vehicles traveling alongside you or approach­ i ng you, there w ill be not iceable correct ive steer­
in g short ly before you leave t he la n e. This will at­
temp t to keep your veh icle in t he la n e.
Appl ies to: veh icles w ithout s ide ass ist : the ready
sys tem does not wa rn yo u if you activate a tu rn
sig nal befo re cr oss ing t he lane ma rker line. In
A ss istance systems
thi s case, it assumes that you are chang ing lanes
intentionally .
Applies to: vehicles wi th adaptive c ruise co ntro l:
there is no correct ive s teer ing or warn ings if th e
system recogni zes a dist inct passing maneuver .
If the conditions are met, traffic jam assist
switches on at speeds under app roximately
40 mp h (65 km/h)

A WARNING ,--
-The system warns the driver t hat the vehicle
is leaving the lane using cor rective steering.
The drive r is always responsible fo r keeping
the vehicle within the lane.
- The system can assist the dr iver in keeping
the vehicle in the lane, but it does not dr ive
by itself. A lways keep your hands o n the
s teer ing whee l.
- Cor rect ive stee ring may not occur in certain
si tua tions, such as d uring heavy b raking.
- There may be cases whe re the camera does
not recogni ze all la n e m ar ker lines. Correc­
tive stee ring can only take pla ce on the s ide
of the vehi cle where lane marker lines are
detected.
- Othe r road st ru ct ures o r obje cts could poss i­
b ly be identifie d uni nten tionally as lane
marker lines . As a res ult, co rrective steerin g
may be unexpected o r may not occ ur.
- T he camera v iew c an be restricte d, for ex ­
ample by vehi cles dr iving ahea d or by ra in,
snow, heavy spray or lig ht shini ng into the
camera. Th is can result in active lane ass ist
not detecting the lane marker lines or de­
tect ing t hem inco rrectly .
- In ce rtain s ituations w he re visibility is low,
the vehicle may switch from an "early" to
"late" steering correct ion.
- Under certain condit ions such as r uts in the
road, a n inclined roadway or crosswinds, the
correct ive steer ing alone may not be enough
to kee p the vehicle in the m iddle of the lane .
- For safety reasons, act ive lane assist must
not be used when there are poor road and/
or weather condit ions such as slippe ry
ro ads, fog, gravel, heavy rain, s now and t he

- The relevant lane marker lines are not detected
(for example, markings in a construction zo ne
or because they are obstructed by snow, dirt,
wate r or light ing) .
- The vehicle speed is below the activation speed
of approximately 40 mph (65 km/h).
- The lane is too narrow or too wide .
- The curve is too narrow.
- The driver's hands are not on the steering
wheel.
