PN eye
Applies to: vehicles with Audi pre sense basic
Audi pre sense basic is automatically active at
speeds of approximately 20 mph (30 km/h) and
higher. The system can trigger the Audi pre sense
preemptive safety measures during emergency
braking and dangerous braking maneuvers as
well as in unstable driving situations, such as
oversteering or understeering.

ZA WARNING
Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
Audi pre sense front
Applies to: vehicles with Audi pre sense front

The Audi pre sense front system uses the data
from the radar sensors and calculates the proba-
bility of a rear-end collision. Within the limits of
the system, an impending collision with the front
of the vehicle can be detected in both urban and
rural speed ranges.
Early warning/acute warning
The system can recognize various dangerous sit-
uations. The early warning occurs if:
— Avehicle driving ahead brakes suddenly
— Your own vehicle approaches a significantly
slower vehicle or stationary vehicle in the direc-
tion of travel
The message Audi pre sense [@) or Audi pre
sense wa and a warning tone will warn you about
the danger.
140
If there is an impending collision with vehicles,
there may also be an acute warning in the form
of sharp braking. You will also be warned by an
indicator in the instrument cluster display. When
this warning occurs, it may only be possible to
avoid a collision by swerving or braking strongly.
Automatic deceleration
If you do not react to the acute warning, Audi pre
sense can brake the vehicle to a full stop within
the limits of the system if the vehicle is traveling
at low speeds. This reduces the vehicle speed in
the event of a collision.
Automatic braking force increase
If Audi pre sense determines that you are not
braking strongly enough when a collision is immi-
nent, it can increase the braking force based on
the situation.

Z\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— Audi pre sense front cannot overcome natu-
ral physical laws. It is a system designed to
assist and it cannot prevent a collision in ev-
ery circumstance. The driver must always in-
tervene. 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.
— Audi pre sense front does not react to cer-
tain objects, such as people/cyclists, ani-
mals, crossing or oncoming vehicles, bars,
railings, or railcars.
— Audi pre sense front may be limited or un-
available when driving in curves.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.

G) Tips
Certain pre sense front functions will switch
off when the ESC is restricted or switched off >

Ne Cea ial
Applies to: vehicles with Audi pre sense city
Audi pre sense city uses data from the camera
and calculates within the limits of the system the
probability of a collision with vehicles and pedes-
trians.
Audi pre sense city is active at speeds of approxi-
mately 6 mph (10 km/h) and higher.
It can warn about pedestrians at speeds up to ap-
proximately 50 mph (85 km/h) and vehicles at
speeds up to approximately 155 mph (250
km/h).
Automatic deceleration is possible at speeds up
to 50 mph (85 km/h).
Early warning/acute warning
The system can recognize various dangerous sit-
uations. The early warning occurs if:
— Avehicle driving ahead brakes suddenly
— Your own vehicle approaches a vehicle in front
of you that is traveling at a significantly slower
speed or that is stationary
— A pedestrian is standing in the lane or is mov-
ing into the lane
A warning tone and the message Audi pre
sense Bo or Audi pre sense wB (depending on ve-
hicle equipment) will warn you about the danger.
If there is an impending collision with vehicles,
there may also be an acute warning in the form
of sharp braking. You will also be warned by an
indicator in the instrument cluster display. When
this warning occurs, it may only be possible to
avoid a collision by swerving or braking strongly.
Automatic deceleration
If you do not react to the acute warning, Audi pre
sense can brake the vehicle to a full stop within
the limits of the system if the vehicle is traveling
at low speeds. This reduces the vehicle speed in
the event of a collision.
Automatic braking force increase
If Audi pre sense determines that you are not
braking strongly enough when a collision is immi-
nent, it can increase the braking force based on
the
situation.

Z\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— Audi pre sense city cannot overcome natural
physical laws. It is a system designed to as-
sist and it cannot prevent a collision in every
circumstance. The driver must always inter-
vene. 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.
— Audi pre sense city does not react to certain
objects, such as animals, crossing or oncom-
ing vehicles, bars, railings, or railcars.
— Audi pre sense city may be limited or un-
available in curves or when it is dark.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.

@) Tips
Certain pre sense front functions will switch
off when the ESC is restricted or switched off
= page 110, when there is a malfunction, or
when the hill hold assist* is switched on

when the detected object is in the “blind
spot”, at the latest.
@ You are slowly passing another vehicle. If the
difference in speed between the two vehicles
is less than 9 mph (15 km/h), the display in
the exterior mirror will turn on.
Information stage
If you do not activate a turn signal, the system
will inform you about objects classified as critical
by turning on the display in the respective exteri-
or mirror. The display remains dim in the infor-
mation stage so that you are not distracted while
looking forward.
Warning stage
Once you activate a turn signal, the system will
inform you about objects classified as critical by
turning on the display in the respective exterior
mirror.
Depending on vehicle equipment, the display
may also provide a warning when the turn signal
is not activated: if driver assist systems detect
that your vehicle is about to leave a lane, the dis-
play will blink to warn you about objects classi-
fied as critical. You can also be warned with cor-
rective steering > page 137, Audi active lane as-
sist.
System limitations
The system uses the data from the radar sensors
at the rear corners of the vehicle > page 116,
fig. 107. They are designed to detect the left and
right adjacent lanes when the road lanes are the
normal width. In some situations, the system
may react to vehicles in your own lane or lanes
that are not directly adjacent to yours, or to ob-
jects on the side of the road. In this case, the dis-
play will turn on even though there is no vehicle
in the critical area. These situations may include:
— Driving on the edge of your own lane
— Narrow lanes
— Curves
— High barriers on the side of the road

Introduction
Depending on the vehicle equipment, various
parking aids will help you when parking and ma-
neuvering.
Parking aid
The parking aid plus assists you while parking
using audio and visual signals to warn you about
objects detected in front of, behind, and next to*
the vehicle > page 147.
The rearview camera shows the area behind the
vehicle in the center display. The lines in the rear-
view camera image help you to park and maneu-
ver > page 149.
The peripheral cameras are an addition to the
rearview camera and help you to see various
areas around the vehicle while parking and ma-
neuvering > page 149.
The rear cross-traffic assist can warn you of ap-
proaching cross traffic when driving in reverse or
exiting a parking space > page 152.
Assisted parking
Park assist helps you to find suitable parking
spaces and to park in and exit these spaces while
the driver monitors the area around the vehicle
and
controls the parking process. Park assist con-
trols the steering movements when parking in
free parking spaces. The driver is still responsible
for accelerating, braking, and shifting gears

Fig. 129 Center display: distance display
If the sensors detect an obstacle, audible and vis-
ual signals will warn you.
Visual warnings
The visual warnings in the center display help you
to detect the critical vehicle area and to estimate
the distance to an obstacle.
Red segments (2) show detected obstacles that
are in your vehicle's path. The red lines 2) mark
the expected direction of travel based on the
steering angle. A white segment (8) indicates a
detected obstacle that is outside of the vehicle's
148
path. The closer your vehicle comes to the obsta-
cle, the closer the segments will move to the ve-
hicle. The collision area has been reached when
the next to last segment is displayed. Obstacles
in the collision area, including those outside of
the vehicle's path, are shown in red. Do not con-
tinue driving farther.
Audio signals
The closer your vehicle gets to a detected obsta-
cle, the shorter the time between the audible sig-
nals. A continuous tone sounds when an obstacle
is less than approximately 1 foot (0.30 m) away
from the front or rear of the vehicle. A continu-
ous tone sounds when an obstacle is less than
approximately 0.7 feet (0.20 m) away from the
sides* of the vehicle. Do not continue driving for-
ward or in reverse >@).

Z\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— The driver is always responsible when enter-
ing or exiting a parking space and during
similar maneuvers.
— Sensors and cameras have spots in which
the surrounding area cannot be detected.
Objects, animals, and people may only be
detected with limitations may not be detect-
ed at all. Always monitor the traffic and the
vehicle's surroundings directly and do not

become distracted.

@) Note
— Parking spaces classified as suitable by the
system may have been detected incorrectly.
The driver must decide if the parking space
displayed is suitable for the vehicle.
— Certain conditions near the parking space
may cause the parking process to fail, such
as if the parking space is near trees or posts,
or if the ground is covered, for example,
with gravel, snow, or ice.
G) Tips
— If you did not drive past a suitable parking
space too quickly, the system can also be ac-
tivated afterward by pressing Pe.
— The Electronic Stabilization Control (ESC)
must not be switched off during the parking
process. If the ESC intervenes, the parking
process will be canceled.
— You can also drive into a perpendicular park-
ing space yourself and then activate the sys-
tem. If this is the case, the front of the vehi-
cle should already be in the space @)
=> page 154, fig. 135 so that the sensors
can measure the space.
— The system is not available when certain as-
sist systems are switched on.
—If there are suitable parking spaces on both
sides of the street, for example on a one-
way street, you can change the side where
the system is searching for parking spaces
by activating the turn signal for the other
side or by pressing on that side in the center
display.
— The park systems do not provide support for
assisted parking on tight curves.
Park assist
General information
Applies to: vehicles with park assist
The park assist helps you when parking and exit-
ing parking spaces after the parking space
search. The park assist takes over the steering of
the vehicle while the driver accelerates, brakes,
and monitors the vehicle's surroundings. Park as-
sist can be interrupted at any time.

ZA WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.

Parking and maneuvering


— The driver is always responsible when enter-
ing or exiting a parking space and during
similar maneuvers.
— Do not use this function if the vehicle cannot
move freely, for example when on a vehicle
jack.
— Sensors and cameras have spots in which
the surrounding area cannot be detected.
Objects, animals, and people may only be
detected with limitations may not be detect-
ed at all. Always monitor the traffic and the
vehicle's surroundings directly and do not
become distracted.

@ Note
— Do not use the park assist systems when
transporting cargo that extends out of the
vehicle, when snow chains are mounted, or
when the parking space is on a hill or in-
cline.
— Park assist guides the vehicle either away
from curbs or onto them if other vehicles
are parked on the curb. Make sure that your
vehicle's tires and rims are not damaged.
Resume control of the vehicle in time or
stop the parking process if needed to pre-
vent damage.
— In parking spaces without curbs, maintain a
distance of at least 19 inches (50 cm) from
walls and buildings in order to reduce the
risk of vehicle damage.
@ Tips
Follow the legal regulations in the country
where you are located when using Park assist.
Parking with the park assists
Applies to: vehicles with park assist
Requirement: a suitable parking space must be
found and selected > page 154. The vehicle must
initially be stationary.
> Select the reverse gear after stopping briefly.
> Remove your hands from the steering wheel.
> Pay attention to the path of the vehicle. If the
traffic situation permits, accelerate carefully
>A.
156
> Follow the visual instructions in the center dis-
play and the warning tones until the parking
process
has ended.
> The indicators in the center display show the
necessary direction of travel. Drive in the direc-
tion indicated by the arrows or symbols on the
roof in the parking aid image @) > page 154,
fig. 136.
Park assist automatically steers the vehicle into
the parking space while the driver presses the
pedals. The maximum parking speed is approxi-
mately 4 mph (7 km/h).

ZA WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— The park assist is an assist system. The driv-
er is still responsible for monitoring the ve-
hicle's surroundings and preventing colli-
sions when using the system.
— When using park assist to drive into or out
of a parking space, the steering wheel turns
quickly on its own. Reaching into the steer-
ing wheel spokes while this is happening can
result in injury.
G) Tips
You can also cancel the driving direction set
by the system by shifting between D and re-
verse gear. Based on the position of the vehi-
cle, the system then calculates the additional
steering and driving directions for maneuver-
ing.
Exiting parking spaces with park assist
Applies to: vehicles with park assist

If you parked the vehicle in a parallel parking
space, park assist can help you drive out of it.
> Start the engine.
> Press the Pe button in the center console.
> Wait until a message appears in the center dis-
play that specifies the direction of travel re-
quired to exit the parking space.
