Lane departure warning
(erreur laced)
Applies to: vehicles with lane departure warning
The lane departure warning can detect lane
marker lines within the limits of the system. If
you are approaching a detected lane marker and
it appears likely that you will leave the lane, the
system can warn you with corrective steering and
a steering wheel vibration, if necessary.
The system functions in the speed range of ap-
proximately 40 mph - 155 mph (65 km/h -
250 km/h).

Driver assistance

If the indicator light turns on, the lane depar-
ture warning is not ready to provide warnings.
This may be due to the following reasons:
— The necessary lane marker lines have not been
detected (for example, in a construction zone
or because the lines are obstructed by snow,
dirt, water, or lighting)
— The speed is below the activation speed
— The lane is too narrow or too wide
— The curve is too narrow
— The driver's hands are not on the steering
wheel
— Visibility is obstructed by a rise or dip.
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 will become inactive after a
short time and will only be active again later.
If the driver does not take over steering, the lane
departure warning will no longer be ready to pro-
vide warnings. If the vehicle is equipped with
emergency assist and it is ready to function, it
will be activated > page 154.
Behavior when a turn signal is active
Applies to: vehicles with side assist: Even if the
system is ready to provide warnings, it will not
warn you if you activate a turn signal before
crossing the lane marker line. In this case, it as-
sumes that you are changing lanes intentionally.
Applies to: vehicles with side assist: If the turn
signal is activated, the lane departure warning is
ready, and a lane change has been classified as
critical by the lane departure warning due to
vehicles traveling beside you or due to approach-
ing vehicles, then a noticeable corrective steering
movement will occur shortly before exiting the
lane. This will attempt to keep your vehicle in the
lane.

ZA WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 118.
— 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.

(i) 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
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.
— The system does not provide any corrective
steering or steering wheel vibrations if it de-
tects that you are passing another vehicle.

Audi pre sense basic
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. Audi pre sense basic can trigger the Audi
pre sense preemptive safety measures during
emergency braking and dangerous braking ma-
neuvers as well as in unstable driving situations,
such as oversteering or understeering.

Z\ WARNING
Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 118.
Audi pre sense front
Applies to: vehicles with Audi pre sense front

The Audi pre sense front uses the data from the
camera and calculates the probability of a rear-
end collision. Within the limits of the system, an
impending frontal impact with vehicles, pedes-
trians), or cyclists!) may be detected in both ur-
ban and rural speed ranges.
Audi pre sense front is active at speeds of approx-
imately
6 mph (10 km/h) and higher. It can react
to pedestrians”) or cyclists!) at speeds up to ap-
proximately 50 mph (85 km/h), and can react to
vehicles at speeds up to approximately 155 mph
(250 km/h).
Early warning/acute warning
The system can recognize various dangerous sit-
uations. The early warning occurs if:
— A vehicle 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 or cyclist!) is standing in the lane
or is moving into the lane
The message Audi pre sense [J and a warning
tone will warn you about the danger.
The brakes may also be applied as an acute warn-
ing when there is an impending collision. 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 front can brake the vehicle to a full stop
within the limits of the system )). 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.
Take-over
If the message Bo Please take over! appears, the
vehicle has been braked to a stop by Audi pre
sense and you must resume control of the vehi-
cle.

ZX WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 118.
— 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 animals, crossing or on-
coming 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.

Fig. 116 Diagram: driving situations and displays in the ex-
terior mirror (example)
General information
Side assist monitors the blind spot and traffic in
the adjacent lanes behind the vehicle. Within sys-
tem limits, side assist can detect traffic that is
approaching from behind and provide a warning
when you are changing lanes and turning. The
system uses the data from the radar sensors at
the rear corners of the vehicle.
The side assist is active at walking speeds and
higher. If an object that is classified as critical is
approaching, the display in the exterior mirror @)
on the corresponding side of the vehicle will light
up.
Driving situations
The system can provide warnings about the fol-
lowing risks:
@ Approaching vehicles: a vehicle may be clas-
sified as critical in some cases, even if it is
farther away. The faster a vehicle ap-
proaches, the sooner the display will turn on.
150
@ Vehicles traveling in the same direction: the
display will turn on if vehicles traveling in the
same direction as your vehicle are classified
as critical. The side assist warns you of all de-
tected vehicles when they are in the “blind
spot” or before they reach that point.
@® Vehicles you are passing: the display only
turns on if you slowly pass a detected vehicle
(difference in speed between the two vehicles
is less than 9 mph (15 km/h)). There is no
display if you pass a vehicle more quickly.
Information stage
At the information level, the side assist informs
you of detected objects that are classified as criti-
cal. This is even possible when your vehicle is sta-
tionary and the turn signal is turned on, so that
the system can also assist you when turning.
From speeds of approximately 6 mph (10 km/h)
and higher, the system will warn you of detected
objects that are classified as critical, even if the
turn signal is not turned on.
The display remains dim in the information stage
so that you are not distracted while looking for-
ward.
Warning stage
If you activate a turn signal and the display flash-
es brightly, 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 144,
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:

4K0012721BD
Driver assistance

— 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
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 118.
— The display may not appear on time when
vehicles are approaching or being passed
