Audi adaptive light
Applies to: vehicles with Audi adaptive light
Audi adaptive light provides better visibility when
driving in the dark. The lights are adapted to the
road conditions based on speed, such as when
driving on expressways, rural roads, at intersec-
tions, and around curves. The adaptive lights only
function when the light switch is in the AUTO po-
sition and the all-weather lights are switched off.
ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 117.
— Automatic headlights are only intended to
assist the driver. The driver is still responsi-
ble for controlling the headlights and may
need to switch them on and off manually
depending on light and visibility conditions.
For example, fog cannot be detected by the
light sensors. So always switch on the low
beams ZO under these weather conditions


and when driving in the dark.

G) Tips
— If the vehicle battery has been discharging
for a while, the parking light may switch off
automatically. Avoid using the parking
lights for several hours.
— When using lighting equipment, the driver
is responsible for adhering to any local ap-
plicable regulations while driving and when
parking the vehicle.
— Only the front headlights turn on when the
daytime running lights are switched on*. In
vehicles in certain markets, the tail lights
will also turn on.
—Incool or damp weather, the inside of the
headlights, turn signals, and tail lights can
fog
over due to the temperature difference
between the inside and outside. They will
clear shortly after switching them on. This
does not affect the service life of the light-
ing.

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 >

tive 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, 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.

Description
Applies to: vehicles with side assist

:



Fig. 120 Driving situations and exterior mirror display
General information
Side assist monitors the blind spot and traffic be-
hind your vehicle and provides assistance when
you are changing lanes. If the system detects an
object approaching and classifies it as critical, the
display @ in the exterior mirror on that side of
the vehicle will turn on,
Driving situations
The side assist warning is active at speeds above
approximately 9 mph (15 km/h) and can help in
situations such as the following:
@ Your vehicle is being passed. The faster an-
other vehicle approaches from behind, the
sooner the display in the outside mirror will
turn on.
@® There are vehicles traveling in the same direc-
tion as you in a lane adjacent to yours. The
display in the exterior mirror will turn on
when the detected object is in the “blind
spot”, at the latest.
@® You are slowly passing another vehicle. If the
difference in speed between the two vehicles
is less than 9 mph (15 km/h), the display in
the exterior mirror will turn on.
Information stage
If you do not activate a turn signal, the system
will inform you about objects classified as critical
by turning on the display in the respective exteri-
or mirror. The display remains dim in the infor-
mation stage so that you are not distracted while
looking forward.
Warning stage
Once you activate a turn signal, the system will
inform you about objects classified as critical by
turning on the display in the respective exterior
mirror.
Depending on vehicle equipment, the display
may also provide a warning when the turn signal
is not activated: if driver assist systems detect
that your vehicle is about to leave a lane, the dis-
play will blink to warn you about objects classi-
fied as critical. You can also be warned with cor-
rective steering > page 141, Audi active lane as-
sist/lane departure warning.
System limitations
The system uses the data from the radar sensors
at the rear corners of the vehicle > page 119,
fig. 102. They are designed to detect the left and
right adjacent lanes when the road lanes are the
normal width. In some situations, the system
may react to vehicles in your own lane or lanes
that are not directly adjacent to yours, or to ob-
jects on the side of the road. In this case, the dis-
play will turn on even though there is no vehicle
in the critical area. These situations may include:
— Driving on the edge of your own lane
— Narrow lanes
— Curves
— High barriers on the side of the road

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