® Corrective steering will be indicated with i.
If the lane departure warning must intervene
for a long period of time, a message will re-
quest the driver to drive in the center of the
lane. The steering wheel can also vibrate to
warn you if lane boundaries are detected dur-
ing a passing maneuver.
The lane departure warning is ready to provide
warnings if an object is detected on at least one
side of the individual lane.
If the | i | indicator light turns on, the lane depar-
ture warning is not ready to provide warnings.
This may occur due to the following system limits
or situations:
— 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 the lane departure warning intervenes multiple
times when no steering activity is detected, the

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 164.
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 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
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 129.
— The system warns the driver that the vehicle
is leaving the lane using corrective steering.

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.

@ 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.

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:

Driver assistance

Driving situations
The situations to which the system reacts de-
pends on the vehicle speed.
Up to speeds of approximately 50 mph
(85 km/h), the system may react to the following
situations:
— Pedestrians and cyclists in your lane
Up to speeds of approximately 155 mph
(250 km/h), the system may react to the follow-
ing situations:
— A vehicle driving ahead clearly applies the
brakes
— When approaching a vehicle ahead that is clear-
ly traveling more slowly
— When approaching a stationary vehicle
Prewarning
To warn about detected dangers, Audi pre
sense o will appear in the instrument cluster
and an audio signal will sound.
A brief application of the brakes
If a collision is imminent, there may be an acute
warning using a brief application of the brakes.
You will also be warned about the danger by an
indicator in the instrument cluster display. You
may only be able to avoid a collision by swerving
or braking strongly.
Automatic braking force increase
If there is an impending collision and you are not
applying the brakes enough, the braking force
may be increased, depending on the situation.
Automatic braking
If you do not react to the acute warning, the sys-
tem may apply the brakes with strong braking
force within the limits of the system in order to
reduce the speed of impact in the event of a colli-
sion.
If the brakes were applied until the vehicle stop-
ped, © Please take over! will appear in the in-
strument cluster and you must take over control
of the vehicle.

ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 129.
— 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.
— In trailer mode, the braking behavior of the
trailer can be different than usual during au-
tomatic braking.
@) Tips
Certain pre sense front functions are switched
off when the hill descent assist is actively con-
trolling the vehicle.
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.

Driver assistance

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.
@® 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, 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 155,
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 129.
— 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:
