Audi pre sense
Introduction
Applies to: vehicles with Audi pre sense
Within the limits of the system, the Audi pre
sense functions can initiate measures in certain
driving situations to protect the vehicle occu-
pants and other road users. Depending on the ve-
hicle equipment, various Audi pre sense systems
may
be installed:
— Audi pre sense basic can react during emergen-
cy and dangerous braking maneuvers and un-
stable driving situations (such as oversteering
or understeering).
— Audi pre sense front) can detect an impending
frontal impact and react with warnings, braking
interventions, and preemptive safety measures
for the vehicle occupants.
— Audi pre sense rear monitors the rear traffic
behind your vehicle and can react to an impend-
ing rear impact.
— Audi pre sense side can detect an impending
side impact from cross-traffic and vehicles com-
ing from the side, and can initiate preemptive
safety measures.
— The swerve assist can help you to steer the ve-
hicle around an obstacle during an evasive ma-
neuver that is detected as critical.
— The turn assist can detect vehicles in the oppo-
site lane as critical during a turning maneuver
and react with braking maneuvers.

Warning stage
If you activate a turn signal and the display flash-
es, side assist is warning about objects that have
been classified as critical.
Depending on the vehicle equipment and other
driver assistance systems, the display may also
flash if you have not activated a turn signal. If
you are approaching a detected lane marker line
and it appears you will be leaving the lane, the
display will warn you about detected vehicles
that are classified as critical. You can also be
warned with corrective steering > page 176,
Lane departure warning.
Detection range
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In some situations, the display
may turn on even though there is no vehicle lo-
cated in the area that is critical for a lane change.
For example:
— If the lanes are narrow or if you are driving on
the edge of your lane. If this is the case, the
system may have detected a vehicle in another
lane that is not adjacent to your current lane.
— If you are driving through a curve. Side assist
may react to a vehicle that is in the same lane
or one lane over from the adjacent lane.
— If side assist reacts to other objects (such as
roadside structures like guard rails).

ZA\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 150.
— The display may not appear on time when
vehicles are approaching or being passed
very quickly.

@ Tips
— If the window glass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be incor-
rect.
— The coverage areas of the sensors > fig. 132
are diagrams and do not represent a true-
to-scale image of the sensor ranges.

General information
The intersection assistant can warn the driver of
approaching cross traffic in complex intersections
> fig. 135.
The system monitors intersections and exit
ramps using the sensors installed in the vehicle
that detect the front and side areas around the
vehicle. Moving objects that are approaching
from behind, such as cars, are detected within
the limits of the system > A\. The system can al-
so warn the driver of a potential collision with de-
tected approaching cross traffic in intersections
and exit ramps with poor visibility.
Requirements for using the intersection
assistant:
— The speed must not be higher than approxi-
mately 18 mph (30 km/h).
— The “D” gear is selected.
Displays, warnings, and braking
— Display: the red arrow (@) can indicate the direc-
tion from which the cross traffic is approaching.
The indicator in the upper display only appears
when the parking aid is activated. For vehicles
with peripheral cameras only in the Front and
Front corner camera views. The display only ap-
pears in the instrument cluster > fig. 136 when
the Driver assistance display is open in the on-
board computer > page 16.
— Warnings: the message Cross traffic! © can
warn about critical cross-traffic when driving
forward. There may also be an audible signal.
— Automatic brake activation: if you do not react
to a warning, a brief braking by the system can
warn you of a potential collision with an ap-
proaching object when driving forward at
speeds up to approximately 6 mph (10 km/h).

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
— Keep enough distance from the curb to
avoid damage to the rims.
— Applies to: vehicles with assisted parking
systems: If you park in short parking spaces
using assisted parking systems, a continu-
ous tone will sound from the parking aid
when the distance to an object is less than
approximately 0.7 feet (0.20 m). Do not
continue driving farther.
G) Tips
—The side area* > page 151, fig. 108 is de-
tected and evaluated when passing. There
may have been changes to the surrounding
area after switching the ignition off and on
again, after opening the doors, or if the ve-
hicle is left stationary for a period of time.
In this case, the area will appear black until
the area has been detected and evaluated.
— If the distance to an obstacle remains con-
stant, the volume of the distance warning
gradually lowers after a few seconds until it
is muted (this does not apply to the continu-
ous tone). If the obstacle comes closer than
it was before the sound was muted, the
tone will sound again. If the obstacle be-
comes farther away than it was before the
sound was muted, no tone will sound. Pay
attention to the vehicle's surroundings
when you start to drive.
