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 105 or > page 106.
@ 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.

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.
—In trailer mode, some assist systems may be
limited, may not react as usual, or may be
unavailable. Please refer to the instructions
for towing a trailer located in > page 101.
— If accessories have been mounted on the
steering wheel, the ability for the steering
systems to react may be limited.

ZA WARNING
There are areas around the vehicle that the
sensors cannot detect. Objects, animals, and
people may only be detected with limitations
may not be detected at all. Always monitor
the traffic and the vehicle's surroundings di-
rectly and do not become distracted.
@) Note
— Obstacles may disappear from the measure-
ment range when approaching them, even if
they were already detected. Under certain
circumstances, the detection and display of
certain surfaces and objects may be limited:
— Items and objects above the coverage
area, for example cars parked bumper-to-
bumper, half-open garage doors, or hang-
ing objects that do not touch the ground
— Low obstacles
— Thin or narrow objects, such as barrier
chains, foliage, poles or fences
— Projecting objects, such as trailer draw
bars
— Objects with certain surfaces and struc-
tures,
such as fabric

Assist systems
@) Tips
— The coverage areas of the sensors > fig. 86
are diagrams and do not represent a true-
to-scale image of the sensor ranges. The ra-
dar sensors are designed to detect the left
and right adjacent lanes when the road
lanes
are the normal width.
— Make sure all the sensors are clean and free
of snow and ice, and that the visual fields
are not covered by stickers, deposits, or any
other obstructions, because this may impair
the function of the systems. Follow the in-
formation about cleaning > page 236.
— Do not use a license plate bracket different
from the one installed by the factory in the
front of the vehicle, because it may impair
the function of dependent systems.
— The sensors can shift from an accident,
manual force, impacts, or from damage to
the radiator grill, bumper, wheel housing,
or underbody. Do not continue using the as-
sistance systems if the sensors have shifted,
because this is unsafe. Have an authorized
Audi dealer or authorized Audi Service Fa-
cility check their function.
— The function of the sensors may be limited
when light and visibility conditions are poor,
for example when driving into a tunnel,
when there is glare, or when there are re-
flective objects.
— External ultrasonic sensors, such as those in
other vehicles, can interfere with the sen-
sors.
—The side area ©)* is detected and evaluated
when passing. There may have been
changes to the surrounding area after
switching the ignition off and on again, af-
ter opening the doors, or if the vehicle is left
stationary for a period of time. In this case,
the area will appear black until the area has
been detected and evaluated.

tect. Objects, animals, and people may only
be detected with limitations may not be de-
tected at all. Always monitor the traffic and
the vehicle's surroundings directly and do not
become distracted. >
Driving information
Driving information
Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps the driver to
stay below a specified maximum speed. A warn-
ing threshold can be set for this purpose.
Once the speed slightly exceeds the stored
threshold, the speed warning system will alert
the driver with an indicator in the instrument
cluster and a warning tone. Once the speed drops
below the stored maximum speed, the indicator
will turn off.
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener-
al speed limit or if there is a specified maximum
speed for winter tires.
G) Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit.

Z\ 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 104.
@) 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.
— These functions depend on how up-to-date
the navigation data’ is.
— Outdated map content in the navigation
system can cause information on the display
to be omitted or incorrect.
— 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.
— 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.

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
you when the cruise control system is in op-
eration. As the driver, you are always respon-
sible 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
hydroplaning), because this increases the
risk of an accident.
— 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.
@) Note
Before driving downhill a long distance ona
steep hill, decrease your speed and select a
lower gear. This makes use of the engine brak-
ing effect and relieves the brakes.
@) Tips
The brake lights turn on when the brakes are
applied automatically.

Adaptive speed/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:
The adaptive speed/cruise assist (called only
adaptive cruise assist in the vehicle display and in
the rest of the Owner's Manual) consists of a
speed and distance control system. It assists the
driver by both regulating the speed and main-
taining the set distance to the vehicle driving
ahead, within the limits of the system. If the sys-
tem detects a vehicle driving ahead, the adaptive
cruise assist can brake and accelerate your vehi-
cle within the limits 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 automatically brakes to match that
vehicle's speed and then maintains the set dis-
tance as much as possible. As soon as the system
does not detect a vehicle driving ahead, adaptive
cruise assist accelerates up to the set speed.
