the indicator lights.
When approaching a vehicle driving ahead, the
adaptive cruise control system brakes to match
that vehicle's speed and then adjusts to the set
distance. If the vehicle driving ahead accelerates,
then the adaptive cruise control will accelerate
up to the speed that you have set.
The following distances can be set:

does not take over steering after multiple driver
intervention requests. The system brakes the ve-
hicle until it is stationary.
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.
If the driver does not take over steering, adaptive
cruise control (with traffic jam assist) will be
switched off. The system brakes the vehicle until
it is stationary.*
Z\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
— The activated traffic jam assist is only an as-
sist system, and the driver is still responsi-
ble for controlling the vehicle. The driver is
especially responsible for braking, steering,
starting to drive, and controlling the speed
and the distance from other vehicles.
— Turn on the traffic jam assist only if the sur-
rounding conditions permit it. Always adapt
your driving style to the current visual,
weather, road, and traffic conditions.
— Switch the traffic jam assist off temporarily
when driving in turning lanes or highway ex-
its. This prevents the vehicle from accelerat-
ing to the stored speed when in these situa-
tions.
G) Tips
— Always keep your hands on the steering
wheel. The driver is always responsible for
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.
— Pay attention to applicable local regulations
relating to driving tasks, leaving space for
emergency vehicles, etc. The driver is always

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 turn
signal is activated, lane assist is ready, and a lane
change has been classified as critical by lane as-
sist due to vehicles traveling beside you or due to
approaching vehicles, then a noticeable correc-
tive steering movement will occur briefly 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 121.
— 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.
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
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.

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 [MM and a warning tone will warn you about
the danger.
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.
ZX WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
— 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

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 is standing in the lane or is mov-
ing into the lane
A warning tone and the message Audi pre
sense Bo or Audi pre sense ww (depending on ve-
hicle equipment) will warn you about the danger.
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.
