Driver assistance

Steering intervention request
If no steering activity is detected or the steering
power from the system is not sufficient, the driv-
er steering intervention request will alert the
driver using audio and visual signals. Take over
the steering and keep your hands on the steering
wheel so that you will be ready to steer at any
time. The system may no longer be ready to pro-
vide warnings after a short time, and it will only
become active again later.
If the driver takes over steering, active lane assist
will be switched off.
Behavior when a turn signal is active
Applies to: vehicles with side assist: The system
will not warn you if you activate a turn signal be-
fore crossing the lane marker line. In this case, it
assumes that you are changing lanes intentional-
ly.
Applies to: vehicles with side assist: If the side
assist system classifies a lane change as critical
due to other vehicles traveling with your vehicle
or approaching your vehicle when your turn sig-
nal is activated, there will be a noticeable steer-
ing correction shortly before your vehicle leaves
the lane. This will attempt to keep your vehicle in
the lane.

ZX WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— 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.
— Corrective steering may not occur at all in
certain situations, such as during heavy
braking. Always be ready to intervene.

G) Tips
— Always keep your hands on the steering
wheel so you can be ready to steer at any
time. The driver is always responsible for

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 >

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
