Lane departure warning
General information
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).
Applies to: vehicles with lane departure warning
and without side assist: Even if the system is
ready, it will not warn you if you activate a turn
signal before crossing the lane marker line. In
this case, it assumes that you are changing lanes
intentionally.
Applies to: vehicles with lane departure warning
in combination 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 approaching

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 assist during an evasive
maneuver recognized as critical with steering
movement and by braking individual wheels in-
dividually.
— The turn assist can detect vehicles in the oppo-
site lane and react with braking maneuvers.

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.
ZA WARNING
Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 115.
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:
—Avehicle 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 Oo 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.
ZA\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 115.
— 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

Side assist
Description
Applies to: vehicles with side assist
:
Fig. 106 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.
@ 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 141,
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: >

Emergency assist
Applies to: vehicles with emergency assist
General information
Within the limits of the system, the emergency
assist detects if the driver is inactive. In these in-
stances, the system warns the driver, assumes
control of the vehicle if necessary, and brings the
vehicle automatically to a stop in the lane.
Regardless of the speed, the emergency assist is
automatically available when the adaptive cruise
assist* is activated. When the adaptive cruise as-
sist* is deactivated, the system is only active at
speeds higher than approximately 40 mph
(65 km/h).
Emergency assist functions
Within the limits of the system, the emergency
assist monitors the driver’s steering, accelerator,
and brake pedal activity. Depending on the se-
verity of the situation, it may initiate visual, au-
dio, and haptic warnings in stages:
— Reduces the speed
— Messages
— Lowers the volume of the Infotainment system
— Audible warning
— Tightening of the safety belt
—A brief application of the brakes
D_ This function is not available in every market and on all ve-
hicle equipment levels.
If the driver remains inactive despite the warn-
ings, the emergency assist controls the vehicle
within the limits of the system:
— The Audi pre sense preemptive safety measures
are triggered > page 143.
— The vehicle will stay in the lane and will be
braked to a stop.
— As soon as the vehicle comes to a full stop, the
emergency flashers are activated and the vehi-
cle prepares for the vehicle passengers to be
rescued. The parking brake is set, “P” gear is
engaged, the doors are unlocked, and the inte-
