Traffic jam assist supports the driver when driv-
ing in traffic jams or in heavy traffic.
In a speed range under 40 mph (65 km/h), the
system can help to keep the vehicle within a lane
calculated by the system. Within the limits of the
system, the system controls the steering auto-
matically when adaptive cruise control is switch-
ed on. Since traffic jam assist is only an assist
system, the driver must always keep his or her
hands on the steering wheel and be ready to
steer. The driver can override the control at any
time by actively steering.
The system is designed for driving on express-
ways and highways.
Requirements for using traffic jam assist:
> The traffic jam assist is preselected in the MMI
settings: Select on the home screen: VEHICLE >
Driver assistance > Traffic jam assist.
> Adaptive cruise control must be switched on
and active > page 129.
If you open the Driver assistance display in the
on-board computer > page 15, the indicator
light and the message Traffic jam assist availa-
ble will turn on when a traffic jam is detected.
Activating or deactivating traffic jam assist
> To activate or deactivate traffic jam assist,
press the > fig. 121 button.
Always switch off traffic jam assist in the
following situations:
— When increased attention is needed from the
driver
— In construction zones
— In city driving
— On stretches of road with curves
—In unclear traffic situations such as at intersec-
tions or toll stations
Indicator lights
Traffic jam assist is available.

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. 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
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras © page 114.
— 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
responsible for following the laws that are
applicable in the location where the vehicle
is being operated.
— If traffic jam assist was deactivated through
the MMI, you can continue operating the
Audi active lane assist using the > fig. 121
button > page 137. The traffic jam assist
functions are no longer available.
— You are not necessarily guided to the center
of your lane.
