Driver assistance

B - Traffic jam assist switches off if the driver
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, such as
or E. 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.*

ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras page 117.
— 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.

@) 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
responsible for following the laws that are
applicable in the location where the vehicle
is being operated.

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, Audi active lane assist is
ready, and a lane change has been classified as
critical by lane assist due to vehicles traveling be-
side you or due to approaching vehicles, then a
noticeable corrective steering movement will oc-
cur briefly before exiting the lane. This will at-
tempt to keep your vehicle in the lane.

ZX WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 117.
— The system warns the driver that the vehicle
is leaving the lane using corrective steering.

If the sensors detect an obstacle, audible and vis-
ual signals will warn you.
Visual warnings
The visual warnings in the center display help you
to detect the critical vehicle area and to estimate
the distance to an obstacle.
Red segments (@) show detected obstacles that
are in your vehicle's path. The red lines @) mark
the expected direction of travel based on the
steering angle. A white segment (3) indicates a
detected obstacle that is outside of the vehicle's
path. The closer your vehicle comes to the obsta-
cle, the closer the segments will move to the ve-
hicle. The collision area has been reached when
the next to last segment is displayed. Obstacles
in the collision area, including those outside of
the vehicle's path, are shown in red. Do not con-
tinue driving farther.
Audio signals
The closer your vehicle gets to a detected obsta-
cle, the shorter the time between the audible sig-
nals. A continuous tone sounds when an obstacle
is less than approximately 1 foot (0.30 m) away
from the front or rear of the vehicle. A continu-
