Early warning /acute warning
The system can provide visual and audible warn­
ings when dangerous situations are detected.
The
early warning may occur if:
- a vehicle driving ahead brakes st rong ly,
131

Ass is tanc e system s
-your vehicle is traveling at speeds between ap ­
proximately 20 to 50 mph (30 to 85 km/h) and
it approaches a stationary vehicle.
- your vehicle is traveling at speeds between ap ­
proximately 20 to 155 mph (30 to 250 km/h)
and it approaches a vehicle that is clearly trav ­
eling more slowly or a veh icle in your direction
o f travel tha t is stopped.
When this warning occurs, it may only be possi ­
b le to avoid a collision by swerving or braking
strong ly. The message
A udi pre sense.
¢ fig. 134 and a warning tone will warn you
about the danger .
If there is an impending collision with vehicles,
there will a lso be an
acute warning in the form of
sharp braking. If you do not react to the acute
warn ing, pre sense front can brake with increas ­
ing force within the limits of the system . T his re­
duces the vehicle speed in the event of a coll i­
sion .
Autom atic deceleration
Depending on the speed, pre sense front can de­
cel erate automatica lly
shortly before a collision:
-if there are stationary vehicles when you are
traveling at speeds up to approx imately 28
mph (45 km/h)
-if there are veh icles dr iv ing or stopped ahead
whe n you are traveling at speeds up to approxi­
mately 155 mph (250 km/h)
Autom atic bra king force inc rea se
If pre sense front determines that you are not
braking strongly enough when a co llision is imm i­
nent, it can inc rease the braking force, depending
on the situation and speed:
-if there are stationary vehicles when you are
traveling at speeds up to approx imately 50
mph (85 km/h)
-if the re are ve hicles driving or stopped ahead
when you are traveling at speeds up to approxi­
mately 155 mph (250 km/h)
A WARNING
Pre sense front cannot ove rcome the laws of
physics . It i s a system des igned to assist and
132
it cannot prevent a coll is io n in eve ry ci rc u m ­
stance . The driver m ust always intervene. The
driver is always respons ible for braking at the
correct time . Do not let the inc reased safety
provided tempt yo u into tak ing risks . This
could inc rease your r isk of a co llision.
-Keep in mind that pre sense front can pro­
vide war nings or b rake unexpectedly. Al­
ways secure a ny cargo or objects that yo u
a re transporting to reduce t he ris k of dam­
a ge or inj ury.
-The system can dep loy in co rre ctly due to
sys tem -specific li mits.
-Please note that the se nsor does not a lways
detect a ll obje cts. Thi s increases the r is k of
a c ollision .
-Pre sense front does not rea ct to ve hicles

Assistance systems
Appl ies to: vehicles w ith Audi side 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 ­
tive steering shortly before you leave the lane.
This will attempt to keep your vehicle in the lane .
Applies to: veh icles without Audi s ide ass ist
The system will not warn you before crossing a
lane marker line if you have activated the turn
signal. In this case, it assumes that you are
changing lanes intentionally.
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
bly 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 rain,
snow, heavy spray light shining into the
camera or by dirt on the window. This can
result in active lane assist not detecting the
lane marker lines or detecting them incor­
rectly.
- Under certain conditions such as ruts in the
road, an inclined 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
134
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 .

IJI,

Ass is tanc e system s
-If the lanes are narrow or i f you 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 t hrough a curve. Side assist
may react to a vehicle that is one lane over
from the adjacent lane .
- If side assist reacts to other objects (such as
high or displaced guard rails).
- In poor weather conditions . The side assist
functions are limited.
Do not cove r the radar
sensors¢ fig . 141 with
stickers, deposits, bicycle whee ls or other ob ­
jects, beca use they wi ll impair the f unction . Do
not use side assist when towing a trailer. For in­
formation on cleaning,
see¢ page 354 .
A WARNING
-Always pay atte ntion to traffic and to the
area aro und your vehicle. Side assist cannot
r ep lace a dr ive r's attent ion. The dr ive r alone
is a lways responsible for lane c hanges and
s imi lar d riving maneuvers.
- In some situat ions, the system may not
func tion or its f un ct io n may be lim ited. Fo r
exa mple:
- If vehicles are approach ing or being le ft
beh ind very quickly. The display may not
tur n on in t ime.
- In poor weather conditions s uch as heavy
rain, snow or heavy mist.
- On very wide lanes, in tight curves, or i f
there is a rise in the road su rface. Vehicles
in the adjacent lane may not be detected
because they are outs ide of the sensor
range.
@ Note
The sensors can be displaced by impacts or
damage to the bumpe r, whee l housing and
underbody. Th is can impa ir the system. Have
an au thor ized A udi dealer or au tho rized Aud i
Serv ice Facility c heck their fu nction .

objects that are approaching, such as cars, are
detected
c:> fig . 142.
If the system detects cr itical cross traffic when
backing out of a parking space, it will react as fol­
lows:
A ssi st a nce systems
- Visual indicator : an indicator appears in the In ­
fotainment system disp lay with a red arrow
symbo l. The arrow points in the d irect ion from
which the object is
approaching ¢ fig. 143.
-Audible warning signal : a continuous tone may
sound as an addit ional indicator when dr iving in
reverse.
- Automat ic brake acti vation : a brief activation
of the brakes may also warn you of a potent ial
collision w ith an approaching object.
The audib le warning signal and the automatic
bra ke activation occur only when driv ing in re ­
verse.
A WARNING
-- The rear cross-traffic assist is an assist sys­
tem and cannot prevent a co llision by itself .
The drive r must always intervene . T he d river

Parking aid
General information
Ap plies to: vehicles with pa rk in g system plus/rearview cam­
era
Depending on your vehicle's equipment, various
parking aids will help you when parking and ma­
neuvering.
The
parking system plus assists you when park­
in g by aud ibly and visua lly indicating objects de­
tected
in front of and behind the veh icle
¢ page 143.
The rearview camera shows the area beh ind the
veh icle in the Infotainment system d isplay. The
l ines in the rearview camera image help you to
park or
maneuver ¢ page 145.
& WARNING
-Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The parking system cannot replace
the driver's attent ion. The driver is always
responsible when enter ing or leaving a park­
ing space and during similar maneuvers.
-Please note that some surfaces, such as
clothing, are not detected by the system.
-Sensors and cameras have blind spots in
which people and objects cannot be detect­
ed . Be especially cautious of small children
and animals.
- Always pay attention to the area around the
vehicle -using the rearview mirror, too .
-The sensors can be displaced by impacts or
damage to the radiator gr ille, bumper,
wheel housing and the underbody . The park ­
ing system may be impa ired as a result.
Have an authorized Audi dealer or author­
ized Audi Serv ice Facility check their func­
tion.
(D Note
-Some objects are not detected or displayed by the system under certain circumstances:
-objects such as barrier chains, trailer draw
bars, vert ical poles or fences
-objects above the sensors such as wall ex ­
tensions
Parking aid
-objects with certain s urfaces or structures
such as chain link fences or powder snow
-If you continue driving closer to a low ob­
ject, it may disappear from the sensor
range . Note that you will no longer be
warned about th is obstacle.
-Keep enough distance from the curb to re­
duce the risk of damage to th e rims.
(I} Tips
-The system may provide a warning even
though there are no obstacles in the cover­
age area in some situations, such as:
-certa in road surfaces or when there is tall
grass
- external ultrasonic sources such as from clean ing vehicles
-in heavy rain, snow, or thick vehicle ex­
haust
-We recommend that you practice parking in
a traff ic -free location or parking lot to be ­
come fam iliar with the system . When doing
this , there shou ld be good light and weath­
er conditions .
-You can change the volume and pitch of the
signa ls as well as the display ¢
page 147.
-What appears in the infotainment display is
somewhat time-delayed .
-The sensors must be kept clean and free of
snow and ice for the parking aid to operate .

Intelligent Technology
Intelligent Technology Electronic Stabilization
Control (ESC)
Description
Elect ronic stabili zation control ( ESC) supports
driver safety. It red uces the risk of slipping and
improves dr iving stabi lity. ESC detects crit ica l sit­
uations such as the vehicle overstee ring and un­
dersteeri ng or the w heels are sp inning. The vehi­
cle is stabilized by app lying the brakes or reduc ­
i n g e ngine torque . When the ESC engages, the
G1 indicato r light bli nks in t he instr ument clus­
t er.
The fo llow ing systems are in tegrated in the ESC:
Anti-lock braking system (ABS)
ABS p reve nts the whee ls from lock ing whe n brak ­
ing. The vehicle can st ill be steered even d uring
hard brak ing. Apply steady press ure to the bra ke
pedal. Do not pump the pedal. A puls ing in t he
b rake pedal indicates that the system is act ing to
s tabili ze the vehicle .
Brake assist system
The brake assist system can decrease brak ing dis­
tance . It inc reases brak ing power when the d river
presses the brake pedal q uick ly in eme rgency sit­
uations . You must press and hold t he b rake pedal
until the dangerous si tuatio n is ove r. In veh icles
w ith adapt ive c ruise con trol*, the bra ke assist
sys te m is more sensitive if t he di stan ce detec ted
t o the veh icle dr iv ing ahead is too small.
Anti-Slip Regulation (ASR)
ASR reduces eng ine power when the drive wheels
beg in s pinning a nd adapts the force to the road
conditions . T his makes it easie r to sta rt, acceler­
a te and dr ive u p hill s.
Electronic differential lock (EDL)
The EDL applies the brakes to a whee l t h at starts
sp inning and transfe rs t he d rive power to t he
other d riving wheel or wh eels ( if the veh icle is
eq uipped w ith all whee l dr ive*) . T his func tion is
no t a vailable at hig her s pee ds .
148
In extreme cases, ED L automat ica lly swi tches off
to keep the b rake o n the bra ked whee l from over ­
h eating. The ve hicle is still wo rking co rrect ly. ED L
will switc h on again automatically when condi­
tions have returned to normal.
Power steering
The ESC can also support veh icle sta bility
th ro ugh stee ring .
Selective wheel torque control
Selective w heel to rque cont rol is used when driv­
in g on curves. The fron t whee l on the in side of
t h e curve or both whee ls on t he i nsid e of the
cu rve are braked se lective ly as needed. This al ­
l ows mo re precise driving in cu rves .
Automatic post-collision braking system
The "automat ic pos t-coll is io n braking syste m"
c a n help t o reduce t he risk of sliding and of addi ­
tion al collisions a fter an acc iden t. If the a irbag
contro l modu le detects a collision above a certa in
vehicle speed, the ve hicle is braked by the ESC.
The
ve hicle does not br ak e automatically if;
- t he dr ive r presses the acce lerato r pedal, or
- the ESC, the b ra ke system or the ve hicle elect ri-
cal sys tem are not func tioning .
A WARNING
-The ES C and i ts in tegra ted systems can not
over co m e the li mits im posed by n atural
p hy sical laws. T h is is es peci ally i mpo rtan t
on s lippery or we t ro ad s. If the sy stem s be­
gi n acting to stabilize yo ur vehicle, you
should immediately a lter your speed to
match the road and t raffic conditions. Do
not let the increased safety provi ded tempt
