Audi active lane assist
Applies to: vehicles with Audi active lane assist
Active lane assist detects lane marker lines with-
in 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 warn-
ing vibration to occur, it must first be switched
on in the Infotainment system. Active lane assist
is ready for operation 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 so it only activates at
speeds above approximately 40 mph (65 km/h)
(depending on the market).
Applies to vehicles with side assist*: If you acti-
vate a turn signal when active lane assist is ready
and it classifies a lane change as critical because
of vehicles traveling alongside you or approach-
ing you, there will be noticeable corrective steer-
ing shortly before you leave the lane. This will at-
tempt to keep your vehicle in the lane.
Applies to vehicles without side assist*: When
the system is ready, it will not warn you if you ac-
tivate the turn signal before crossing the lane
marker line. In this case, it assumes that you are
changing lanes intentionally.

)) The corrective steering function is not available in all mar-
kets.
72


Z\ 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 assist the driver in keeping
the vehicle in the lane, but it does not drive
by itself. Always 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 exam-
ple 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.
— Incertain situations where visibility is low,
the vehicle may switch internally from “ear-
ly” to “late” steering correction )).
— 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 roads,
fog, gravel, heavy rain, snow and the poten-
tial for hydroplaning. Using active lane as-
sist under these conditions may increase the
risk of a crash.

Bg Ready: the indicator light turns on when the
system is ready for use. The system can now be
operated.
Not ready: the indicator light turns on if the
system is switched on but is inoperable. This may
be due to the following reasons:
— There is no lane marker line
— The relevant lane marker lines are not detected
(for example, markings in a construction zone
or because they are obstructed by snow, dirt,
water or lighting)
— The vehicle speed is below the activation speed
of approximately 40 mph (65 km/h) (the speed
may vary depending on your country)
— The lane is too narrow or too wide
— The curve is too narrow
— The driver's hands are not on the steering
wheel

Audi drive select (drive
settings)
Introduction
Applies to: vehicles with Audi drive select
Drive select makes it possible to experience dif-
ferent types of vehicle characteristics in one vehi-
cle. The driver can select from three modes,
Comfort,
Auto, and Dynamic, using the sist but-
ton in the center console or by using the Infotain-
ment system. This allows you to switch between
a sporty and a comfortable driving mode, for ex-
ample. In the Individual mode, the settings can
be adjusted to your personal preferences. This
makes it possible to combine settings such as a
sporty engine setting with light steering.

Z\ WARNING
Using Audi drive select incorrectly can lead to
collisions, other accidents and serious inju-
ries.

Parking aid

Parking aid
Introduction
Applies to: vehicles with rear parking system/parking system
plus
Depending on the vehicle equipment, various
parking aids will help you when parking and ma-
neuvering.
The rear parking system is an audible parking aid
that warns you of obstacles behind the vehicle
=> page 81.
The parking system plus assists you while park-
ing by audibly and visually warning you of objects
detected in front of and behind the vehicle
=> page 81.
The rearview camera shows the area behind the
vehicle in the Infotainment system display. The
lines in the rearview camera image help you to
park or maneuver > page 82.

ZA 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 exiting 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.
— 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.
— Make sure the sensors are not obstructed by
stickers, deposits or other materials. If they
are, the sensor function could be impaired.
For additional information on cleaning, see
=> page 262.

@) 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
— 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.
— Maintain enough distance from the curb to
reduce the risk of damage to the rims.
@) Tips
— The 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. Practice
parking in good light and weather condi-
tions.
— You can change the volume of the signals.
— What appears in the display is slightly de-
layed.
— The sensors must be kept clean and free of
snow and ice for the parking aid to operate.

Electronic stabilization
control (ESC)
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critical sit-
uations such as the vehicle oversteering and un-
dersteering or the wheels are spinning. The
brakes are applied or the engine torque is re-
duced in order to stabilize the vehicle. When the
ESC engages, the B indicator light blinks in the
instrument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak-
ing. The vehicle can still be steered even during
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal indicates that the system is acting to
stabilize the vehicle.
Brake assist system
The brake assist system can decrease braking dis-
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit-
uations. You must press and hold the brake pedal
until the dangerous situation is over.
Anti-Slip Regulation (ASR)
ASR reduces drive power when the drive wheels
begin spinning and adapts the power to the road
conditions. This makes it easier to start, acceler-
ate and drive up hills.
Electronic Differential Lock (EDL)
The EDL applies the brakes to wheels that are
slipping and transfers the drive power to the oth-
er wheels. This function is not available at higher
speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over-
heating. The vehicle is still functioning correctly.
86
EDL will switch on again automatically when con-
ditions have returned to normal.
Power steering
The ESC can also support vehicle stability
through steering.
Selective wheel torque control
Selective wheel torque control is used when driv-
ing on curves. Braking is targeted toward the
wheels on the inside of the curve as needed. This
allows more precise driving in curves.
Automatic post-collision braking system
The automatic post-collision braking system can
help to reduce the risk of sliding and of addition-
al collisions after an accident. If the airbag con-
trol module detects a collision above a certain ve-
hicle speed, the vehicle is braked by the ESC.
The vehicle does not brake automatically if one of
the following occurs:
— The driver presses the accelerator pedal
—The braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system
— The ESC, the brake system, or the vehicle elec-
trical system is not functioning

ZA WARNING
— The ESC and its integrated systems cannot
overcome the limits imposed by natural
physical laws. This is especially important on
slippery or wet roads. If the systems begin
acting to stabilize your vehicle, you should
immediately alter your speed to match the
road and traffic conditions. Do not let the in-
creased safety provided tempt you into tak-
ing risks. This could increase your risk of a
collision.
— Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv-
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre-
vent collisions - there is still a risk of acci-
dents!

— There is no vehicle stabilization when
ESC/ASR are switched off.

@) Tips
— When the cruise control system* is switched
on, ESC/ASR cannot be switched off or sport
mode cannot be switched on.
— Malfunctions in the rear spoiler or the Audi
magnetic ride may make it impossible to
switch the ESC/ASR off or to switch sport
mode on.
Brakes
You can apply the vehicle's brakes using the brake
pedal.
Operating noise
Noises may occur when braking depending on the
speed, braking force, and outside conditions such
as temperature and humidity.
Braking effect
The response time from the brakes depends on
the weather and environmental conditions. To
ensure the optimum braking effect, the brake
system is cleaned at regular intervals. This is
done by applying the brake pads to the brake ro-
tors for a short period of time when driving at
high speeds when the windshield wipers are
switched on.
If the brake system becomes damp, for example
after driving in heavy rain, the braking effect may
be delayed. Other factors that could temporarily
increase the response time of the brakes include:
— Wet conditions
— Low temperatures, ice, and snow
— Roads covered in salt
— Dirty brake pads
Corrosion
Corrosion may form on the brake rotors if there is
no heavy braking, if the vehicle is not driven for
long periods of time, or if the vehicle is not driv-
en
frequently or for long distances. In this case,
braking heavily several times while driving at
high speeds can clean the brake rotors > A\.
838
Brake pads
New brake pads do not achieve their full braking
effect during the first 250 miles (400 km). They
must be “broken in” first. However, you can com-
pensate for the slightly reduced braking force by
pressing firmly on the brake pedal. Avoid heavy
braking during the break-in period.
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions.
Brake pad wear increases when driving frequently
in the city or short distances or when using a very
sporty driving style.
Ceramic brakes
Applies to: vehicles with ceramic brakes
Ceramic brakes provide excellent deceleration
rates.
The break-in period for new ceramic brakes may
be significantly longer than for standard brake
rotors. Due to the properties of the material,
they may cause noises at lower speeds. Ceramic
brakes also absorb more moisture in wet condi-
tions. Therefore, there will temporarily be less
braking force than when the brakes are dry. You
can compensate for this by pressing the brake
pedal harder.

A WARNING
— Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en-
danger other road users and increase the
risk of an accident.
— Due to the risk of injury, only have an au-
thorized Audi dealer or authorized Audi
Service Facility work on the brake system.
Incorrect repairs could impair the function.
— Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident.
— Depending on vehicle equipment, the brake
pedal may move downward automatically
during autonomous braking maneuvers. To
reduce the risk of injury, do not place your
foot under the brake pedal.
