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 .

the cause:
-There is no lane marker line.
-The relevant lane marker lines are not detected
(for example, mark ings in a construction zone
or because they are obstructed by snow, dirt,
water or lighting).
-The veh icle speed is below the activation speed
of approx imately 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.

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

-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 ¢

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-

Brake booster
The brake booster amplifies the pressu re yo u ap­
p ly to the brake pedal. It only operates while the
engine is running or when the ignition is switched
on (plug-in hybrid drive*) .
A WARNING
- Only apply the brakes for the purpose of
cleaning the brake system when road and
traff ic conditions permit. You must not en­
danger other road users. This increases the
r isk of an accident .
-
-Never let the vehicle roll while the engine is
stopped because this increases the risk of an
acc ident.
- Depend ing on the veh icle equipment, the
brake pedal may be pulled downward when
the vehicle automatically initiates b rak ing.
- Never place objects in the driver's footwell.
An object could end up in the area around
the pedals and prevent you from using
them. You wo uld not be able to use the ped­
als if sudden driving or braking mane uvers
were needed, which increases the risk of an
accident.
- Only use floor mats that do not obstruct the
area around the pedals and that can be se­
curely fastened in the footwe lls.
- T o reduce the risk of injury, do not place
your foot under the brake pedal.
(Llj) Note
-Never let the brakes "rub" by pressing the
pedal lightly when braking is not actually
necessary. This causes the brakes to over­
heat and increases braking distance and
causes wear.
- Before driving on a long stretch with steep
slopes, reduce your speed and shift to the
next lower gear This makes use of the en­
gine braking effect and relieves the brakes.
If you need to brake add it ionally, brake in
i ntervals and not cont inuously.
Intelligent Technology
(D Tips
- If the brake booster is not working, you
must press the brake pedal with much more
force than normal.
- If you retrofit your vehicle with a front spoi l­
er, wheel covers or simi lar items, make sure
that the air flow to the front wheels is not
interrupted. Otherwise the brake system
can become too hot.
Electromechanical

The electromechanical steering supports the
driver's steering movements.
Power steering adapts electronically based on
the ve hicle speed.
Indicator lights and messages
• Do not drive vehicle: steering defective
If this indicator light turns on and stays on and
th is message appears, the power steering may
