Audi pre sense front
Applies to: vehicles with Audi pre sense front
Audi pre sense front provides the same scope of
functions as Audi pre sense city, with a few ex-
ceptions > page 153. The system has an exten-
sive field of view due to additional sensors that
are installed. Because of this, vehicles that are
braking or traveling significantly more slowly can
be detected earlier and more clearly, depending
on the limits of the system.
The following features apply to Audi pre sense
front:
— Automatic braking interventions are available
at vehicle speeds up to approximately 155 mph
(250 km/h)
— The system does not detect pedestrians

tain objects, such as pedestrians, animals,
crossing or oncoming vehicles, bars, railings,
or railcars.

154
Audi pre sense rear
Applies to: vehicles with Audi pre sense rear
Within the limits of the system, Audi pre sense
rear uses data from radar sensors at the rear cor-
ners of the vehicle and calculates the probability
of a rear-end collision with the vehicle behind
you.
Audi pre sense preemptive safety measures can
be initiated if the risk of a collision with the vehi-
cle behind you is detected.

Z\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 126.
— Audi pre sense rear does not react to pedes-
trians, animals, crossing objects, and ob-
jects not detected as vehicles.

off if there is a malfunction in the side assist
system.
Swerve assist
Applies to: vehicles with swerve assist

The swerve assist can help you to steer the vehi-
cle around an obstacle detected in a critical area.
If you avoid an obstacle after the acute warning,
then the swerve assist assists you by applying
slight steering adjustment to correct your steer-
ing wheel angle as long as you are actively steer-
ing. Swerve assist is available at speeds between
approximately 20 mph (30 km/h) and 90 mph
(150 km/h).

e|


Fig. 127 Driving situations and exterior mirror display
General information
Side assist monitors the blind spot and traffic be-
hind your vehicle and provides assistance when
you are changing lanes. If the system detects an
object approaching and classifies it as critical, the
display @ in the exterior mirror on that side of
the vehicle will turn on,
Driving situations
The side assist warning is active at speeds above
approximately 9 mph (15 km/h) and can help in
situations such as the following:
@ Your vehicle is being passed. The faster an-
other vehicle approaches from behind, the
sooner the display in the outside mirror will
turn on.
@® There are vehicles traveling in the same direc-
tion as you in a lane adjacent to yours. The
display in the exterior mirror will turn 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
156
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 150, Audi active lane as-
sist/lane departure warning.
System limitations
The system uses the data from the radar sensors
at the rear corners of the vehicle > page 128,
fig. 109. 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

Z\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 126. >

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 (@) 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
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 >).
