Assist systems
General information
Safety precautions

ZA WARNING
— As the driver, you are always completely re-
sponsible for all driving tasks. The assist
systems cannot replace the driver's atten-
tion. Give your full attention to driving the
vehicle, and be ready to intervene in the
traffic situation at all times.
— Activate the assist systems only if the sur-
rounding conditions permit it. Always adapt
your driving style to the current visual,
weather, road, and traffic conditions.
— 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
driving.
— For the assist systems to be able to react
correctly, the function of the sensors and
cameras must not be restricted. Note the in-
formation on sensors and cameras
=> page 155.

@ Tips
— Pay attention to applicable local regulations
relating to driving tasks, leaving space for
emergency vehicles, vehicle distance, speed,
parking location, wheel placement, etc. The
driver is always responsible for following
the laws that are applicable in the location
where the vehicle is being operated.
— You can cancel a steering or braking inter-
vention by the system, by braking or accel-
erating noticeably, steering, or deactivating
the respective assist system.
— Always check the assist systems settings be-
fore driving. The settings could have been
changed, for example, by other drivers or if
another personal profile was used.

System limitations
ZA\ WARNING
— The use of an assist system cannot over-
come the natural laws of physics. A collision
cannot be prevented in certain circumstan-
ces.
— Warnings, messages, or indicator lights may
not be displayed or initiated on time or cor-
rectly, for example, if vehicles are approach-
ing very fast.
— Corrective interventions by the assist sys-
tems, such as steering or braking interven-
tions, may not be sufficient or they may not
occur. Always be ready to intervene.
G) Tips
— Due to the system limitations when detect-
ing the surrounding area, the systems may
warn or intervene unexpectedly or too late
in certain situations. The assist systems may
also interpret a driving maneuver incorrectly
and then warn the driver unexpectedly.
— The systems may not function as expected
in unusual driving situations, such as driving
offroad, on unpaved roads, on loose ground,
on inclines, or on grooves in the road.
— The systems may not function correctly in
unclear traffic situations, such as turning
lanes, exit ramps, construction zones, rises
or dips that obstruct visibility, intersections,
toll stations, or city traffic.
— The detection of the surrounding area can
be limited, for example by vehicles driving
ahead or by rain, snow, heavy spray, or light
shining into the camera.
— If accessories have been mounted on the
steering wheel, the ability for the steering
systems to react may be limited.

Traffic light information
Applies to: vehicles with traffic light information

Fig. 121 Instrument cluster: traffic light information dis-
play
The traffic light information gives you a speed
recommendation in order to reach the next traffic
light when it is green @, or it informs you of the
wait time at the next red light 2). Once traffic
light
data is received, the traffic light information
will be displayed in the instrument cluster and in
the head-up display*. If the vehicle is in an area
with traffic light information but cannot receive a
traffic light signal, then a gray traffic light sym-
bol will be displayed @).
General information
The traffic light information is subject to system
limitations and may be unavailable or only parti-
ally available in the following situations:
—If the permitted speed limit is exceeded
— If driving below a certain speed limit
— If the next traffic light is less than approxi-
mately 100 feet (30 m) away
— If the estimated wait time at a red light is less
than four seconds
— If there is no traffic light data available
— If emergency response vehicles or public transit
systems are active
— If traffic lights are in construction zones or be-
ing serviced
— If there are warnings from the camera-based
traffic sign recognition*
— If the camera-based traffic sign recognition* is
malfunctioning or not available
—If the data connection has been interrupted
— If data transmission is deactivated in the priva-
cy settings
— If the subscription has expired
If this is the case, the menu item will be grayed-
out or it will not be possible to select it.

ZA\ WARNING
— When traffic light information is shown, al-
so always pay attention to the traffic situa-
tion, the distance to other vehicles and the
area around the vehicle. The driver is always
responsible for assessing the traffic situa-
tion.
— Always adapt your speed to the current
weather, road and traffic conditions. The dis-
played information must never cause you to
ignore legal traffic regulations and pose a
safety risk.
— Regardless of the traffic light information,
you should always monitor your speed using
the speedometer and make sure you are ad-
hering to the legal speed limit.
— The traffic light information does not adjust
your vehicle's speed to the speed recom-
mendation shown in the display.
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 154.
(i) Tips
— Traffic light information was only available
in select cities at the time this manual was
printed.
— Traffic light information is not available na-
tionwide.
— The functions depend on the navigation da-
ta* being up-to-date and correct identifica-
tion by the traffic sign recognition*.
— Incorrect values from the camera-based
traffic sign recognition* or outdated naviga-
tion system* map data can result in missing
or incorrect display images.
— Certain traffic lights can automatically ad-
just to the current traffic situation. If this
occurs, the display of traffic light informa-
tion can change suddenly.

Driver assistance
Cruise control system
Applies to: vehicles with cruise control system
The cruise control system assists the driver in
maintaining a constant speed above approxi-
mately 15 mph (20 km/h). The system maintains
the desired speed by braking and accelerating.

ZA WARNING
— Always pay attention to the traffic around
your vehicle when the cruise control system
is in operation. As the driver, you are always
responsible for controlling your vehicle
speed and the distance between your vehicle
and
other vehicles.
— For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads, and when road conditions are
poor (such as ice, fog, gravel, heavy rain,
and conditions that could lead to hydroplan-
ing), because this increases the risk of an ac-
cident.
— Switch the cruise control off temporarily
when driving in turning lanes, highway exits,
or in construction zones.
—To reduce the risk of an accident, you should
only resume the stored speed if it is suitable
for the current traffic conditions.


C) Note
— Conventional drive system: Before driving
downhill a long distance on a steep hill, de-
crease your speed and select a lower gear.
This makes use of the engine braking effect
and reduces the load placed on the brakes.
— Plug-in hybrid drive: Before driving downhill
a long distance on a steep hill, decrease
your speed and use the braking effect of re-
cuperation > page 118. This reduces the
load on the brakes.
@ Tips
The brake lights turn on when the brakes are
applied automatically.

sensors > page 156, fig. 117 and try to turn on
the systems again later.
If the malfunction remains, drive to an author-
ized Audi dealer or authorized Audi Service Facili-
ty immediately to have the malfunction correct-
ed.

ZA\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 154.
— Pay attention to traffic and the area around
your vehicle when predictive control is
switched on. The driver is always responsible
for assessing the traffic situation.
— The system does not consider “right of way”
rules and does not respond to traffic lights,
so lack of driver attention in these situations
can increase the risk of an accident.
— The speed when driving through curves may
be different from what you as a driver would
do or may not be suitable for the weather
and road conditions. If necessary, apply the
brakes and reduce the selected speed to be
maintained in the Adjustment to curves
along route setting to reduce the risk of an
accident.

G) Tips
— Predictive control can exceed or drop below
the maximum permitted speed. The driver
is responsible for adhering to the permitted
speed limit.
— The traffic signs on the road always take pri-
ority over the display. The driver is always
responsible for adhering to the regulations
applicable in the country where the vehicle
is being operated.
—If a speed limit is detected, the marking @
of the set speed limit will be adjusted even
if the adaptive cruise assist is not actively
regulating.
— Control by the system depends on which
adaptive cruise assist driving program is set
or on the selected Audi drive select* mode.

YD In certain countries
170
— After switching on the ignition and first
driving onto a freeway or similar road with-
out a speed limit, the system will regulate
the speed to 80 mph (130 km/h). Then
the system adjusts to the last speed set by
the driver.
— There is no adaptation to speed limits when
driving through highway interchanges and
when driving on or off the expressway.
— The system can fail to provide control or the
control may be faulty if the values from the
camera-based traffic sign recognition* are
incorrect or the navigation system map data
is outdated.
— When route guidance is switched on, the
system adapts to the route provided by the
navigation system. Driving without route
guidance or leaving a route can result in
faulty control.
— Certain settings are stored automatically in
the active personal profile.
Adaptive cruise assist
General information
Applies to: vehicles with adaptive cruise assist
Depending on the vehicle equipment, the adap-
tive cruise assist may consist of the following
functions:
Within the limits of the system, the adaptive
speed and distance control assists the driver in
controlling the speed and the set distance to the
vehicle driving ahead. If the system detects a ve-
hicle driving ahead, the adaptive cruise assist can
brake and accelerate your vehicle within the lim-
its of the system. On open roads with no traffic, it
functions like a cruise control system. The stored
speed is maintained. When approaching a vehicle
driving ahead, the adaptive cruise assist auto-
matically brakes to match that vehicle's speed
and then maintains the set distance as much as
possible. As soon as the system does not detect a
vehicle driving ahead, adaptive cruise assist ac-
celerates up to the set speed.

Driver assistance

— The adaptive cruise assist does not respond to
people, animals, or objects that are crossing or
approaching from the opposite direction.

Z\ WARNING
Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 154.

Lane departure warning
(erreur laced)
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: The system will not warn
you before crossing a lane marker line if you have
activated the turn signal. In this case, it assumes
that you are changing lanes intentionally.
Applies to: vehicles with lane departure warning
combined with side assist: A noticeable corrective
steering movement will occur briefly before the
vehicle exits the lane if the turn signal is activat-
ed, the lane departure warning is ready, anda
lane change has been classified as critical by the
