2017 AUDI A3 SEDAN light

Assistance systems
-Due to the interlinking of various vehicle sys­
tems, critica l driving situations can be detected
by
pre sense basic and measures for preventa­
tive occupant protection are can be initiated.
-The pre sense front uses the data from the ra­
dar sensors and calcu lates the probability of an
accident
c> page 127. An impending collision
with vehicles can be detected within the limits
of the system . In this case, the system warns
the driver visually, acoustically and with a jerk
on the brakes if necessary. If needed, it can i ni­
tiate a partia l or full dece le rat ion to reduce the
collision speed o r to avoid the coll ision unde r
ce rtain c ircumstances. In conjunction with pre
sense basic, the front safety belts are also re­
versib ly tensioned when needed . The pre sense
front is also active when adaptive cruise con­
trol* is sw itched off.
.,&. WARNING
Also follow the general instructions found in
c> .&. in General information on page 127.
(i) Tips
-Certain pre sense functions switch off when
driving in reverse.
-The pre sense functions may not be availa­ ble if there is a malfunction in the ESC sys­
tem or the airbag contro l module.
-Note that the reversible belt tensioner on
the front passenger's side deactivates when
the front passenger's a irbag is deactivated .
-Switch the pre sense off when you are not
us ing public streets or when loading the ve­
hicle onto a vehicle carr ier, train, ship or
other type of transportation. This can pre­
vent an undes ired intervention from the pre
sense system.
Audi pre sense basic
Description
Applies to: veh icles with Audi pre sense basic
The pre sense basic funct ions are activated at a
speed of approximately 20 mph (30 km/h) or h igher.
134 The following
functions can be triggered under
certain conditions within the limits of the sys ­
tem:
-Tensioning of the safety bel ts (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.
-Initiating the closing of the windows and the
panorama glass roof* (for examp le when un­
der- or oversteering).
Audi drive select* : the trigger times are adjusted
depending on the mode selected.
Audi pre sense front
· Description
Applies to: vehicles with Audi pre sense front
Within the limits of the system and depending
on the situation and speed, pre sense front can
warn you about impending collisions with sta­
tionary, stopped, and moving vehicles and ini ­
tiate appropriate braking measures.
If detection is not possib le, then pre sense front
does not react.
The following func tions trigger in conjunction
with pre sense basic at corresponding vehicle
speeds :
-Reversible tens ion ing of the front safety belts.
-Closing the windows and panorama glass roof*.

Audi active lane assist
Description
Applies to: vehicles with Audi active lane assist
Active lane assist (lane departure warning) de­
tects lane marker lines within the limits of the
system using a camera in the windshield. If you
are approaching a detected lane marker line and
it appears likely that you will leave the lane, the
system will 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 first be switched 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 driving on express­
ways and highways and therefore only activates
at speeds above approximately 40 mph (65 km/
h).
Applies to: vehicles with 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
.,.

a, a, ..... N
" N ..... 0 N > 00
corrective steering shortly before you leave the lane . This will attempt to keep your vehicle in the
lane .
Appl ies to: veh icles without Audi sid e assist
The system will not warn you before crossing a
lane marker line if you have activated the turn
signal. In this case , it ass umes that you are
changing lanes intent ionally.
& WARNING
- The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The driver is always responsib le 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 brak ing.
- There may be cases where the camera does not recogni ze all lane marker lines. Correc­
t ive steering can only take p lace on the side
of the veh icle 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 restr icted, for ex­
amp le by vehicles driv ing ahead or by rain,
snow, heavy spray light shining into the
camera or by d irt on the window. This can
result in active lane ass ist not detecting the
lane marker l ines 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 m ust
not be used when there are poor road and/
or weather conditions such as slippery
roads, fog, gravel, heavy ra in, snow and the
potent ial for hydroplaning . Using active lane
assist unde r these conditions may increase
the risk of a crash.

Parking systems
Parking systems
General information
A ppl ies to: ve hicles w ith parking 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
ing by audibly and visually indicating objects de­
tected
in front of and behind the vehicle
¢page 147.
The rearview camera shows the area behind the
vehicle in the Infotainment system display. This display assists you when you are cross or parallel parking. The parking system plus functions are
also available ¢
page 148.
A 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 attention. The driver is always
responsible when entering 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 -us ing the rearview mirror, too.
-The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody . The park­
ing system may be impaired as a result.
Have an authorized Audi dealer or author­
ized Audi Service 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, vertical poles or fences
146
-objects above the sensors such as wall ex­
tensions
-objects with certain surfaces 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 this obstacle.
-Keep enough distance from the curb to re­
duce the risk of damage to the rims.
(D Tips
-T he system may provide a warning even
though there are no obstacles in the cover­ age area in some situations, such as:
-certain road surfaces or when there is tall
grass .
-external ultrasonic sources such as from
cleaning vehicles.
-in heavy rain, snow, or thick vehicle ex­
haust.
-We recommend that you practice parking in
a traffic-free location or parking lot to be­
come familiar 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
signals as well as the display¢
page 150.
-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 Electronic Stabilization
Control (ESC)
Description
Electronic Stabilization Control ( ESC) supports
driver safety . It reduces the risk of slipping and
improves dr iving stability. ESC detects critica l sit­
uations such as the vehicle oversteering and un­
dersteer ing or the wheels are spinning. The vehi­
cle is stabilized by apply ing the brakes or reduc ­
ing engine torque . When the ESC engages, the
G1 indicato r light b links in the instrume nt clus­
ter.
The follow ing systems are integrated in the ESC:
Anti-loc k bra king system (ABS)
ABS prevents the whee ls from locking when brak­
ing. The vehicle can still be steered even during
hard brak ing. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
b rake pedal indicates that the system is act ing to
stabilize the vehicle .
Brake a ssist system
The brake assist system can decrease braking dis­
tance. It increases brak ing power when the driver
presses the brake pedal quick ly in emergency sit­
uations . You must press and hold the brake pedal
u nti l the dangerous sit uat io n is ove r. In veh icles
with adaptive cr uise contro l*, the bra ke assist
s ys tem is more sensitive if t he d istance detec ted
to the veh icle dr iv ing ahe ad is too small.
Anti -slip regulation (ASR)
ASR reduces eng ine power when the drive wheels
begin spinning and adapts the force to the road
conditions . This makes i t eas ie r to sta rt, acceler­
ate and dr ive up hill s.
Electronic differential lock (EDL )
The EDL applies the brakes to a wheel that starts
spinning and transfers t he drive power to the
other driving wheel or wheels ( if the veh icle is
eq uipped w ith all whee l dr ive*) . T his function is
n o t available at higher speeds.
Intellig ent Technology
In extreme cases, ED L automat ica lly switches off
to keep the brake o n the braked whee l from over­
heating. The veh icle is still working correct ly. EDL
will switch on again automatically when condi­
t ions have returned to normal.
Ste ering recommendation
The ESC he lps to s tabilize the vehicle by changing
the steering torque.
Select ive wheel torque control
Se lective wheel to rque cont rol is used w hen driv­
i ng on curves. The fron t whee l on the inside of
the curve or bo th wheels on the i nside of the
c u rve are braked se lective ly as needed . This al­
l ows more precise driving in c urves.
Automatic post-collision braking system
T he "automat ic pos t-collision braking system"
c an help to reduce the risk of sliding an d of addi ­
tiona l co llisions a fter an acciden t. If the ai rbag
contro l modu le detects a co llision above a certain
vehicle speed, the veh icle is bra ked by the ESC.
T he vehicle does not bra ke autorn,;1tically if;
- t he dr ive r presses the acce le rator pedal, or
- the ESC, the brake system or the veh icle elect ri-
cal system are not functioning .
A WARNING
-The ESC and its integ rated systems cannot
overcome the lim its imposed by natura l
phys ic al laws. This is especially important
on sli ppery or wet roads . If the sy stems be­
gin acting to stabilize your vehicle, you
should immediately alter your speed to
match the road and traffic conditions. Do
not let the inc reased safety provided tempt
you into taking risks. This could increase
your r isk of a coll is ion.
- Please n ote the r isk of a coll is ion increases
when dr iv ing fast, especially t hrough curves
a nd on slippery or wet roads, and when dr iv­
ing too close to objects ahead. The ESC and
its integrated systems ca nnot always pre­
vent collisions
-there is st ill a ris k of ac ci-
dents!
