Assist systems
General information
Sica eel delay
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 116.
@ 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.
@) 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.

Fig. 82 Diagram: coverage area of the rearview camera
The assist systems analyze the data from various
sensors and cameras installed in the vehicle. Do
not use any assist systems if there is damage to
the vehicle in an area where sensors and cameras
are located or on the vehicle underbody, or if the
vehicle was involved in a collision. The functional-
ity of the sensors and cameras could be impaired,
or they could malfunction. Have an authorized
Audi dealer or authorized Audi Service Facility
check their function.

Radar sensors
Depending on the vehicle equipment, the area
surrounding the entire vehicle may be detected
fig. 81 ©.
The wheel sensors on the rear corners of the vehi-
cle are positioned so that the adjacent lanes to
the left and right are detected on roads with a
normal lane width.
The radar sensors can detect vehicles traveling up
to approximately 650 feet (200 m) ahead.
Ultrasonic sensors
Depending on vehicle equipment, various areas
may be displayed in the MMI using the ultrasonic
sensors > fig. 81.
The range of the displays depends on the location
of the ultrasonic sensors:
@ Approximately 4 ft (1.20 m)
® Approximately 3 ft (0.90 m)
@® Approximately 5.2 ft (1.60 m)
© Approximately 3 ft (0.90 m)
Peripheral cameras*
Use the camera image on the display to assist you
only if it shows a good, clear picture. Keep in
mind that the image in the display is enlarged
and distorted. Under certain circumstances, ob-
jects may appear different and unclear on the dis-
play.
The rearview camera can only detect the area
marked in red > fig. 82. Only this area is dis-
played on the upper display > A\.
Z\ WARNING
Sensors and cameras have spots in which the
surrounding area cannot be detected. 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 directly and do not become dis-
tracted. >

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.
() 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 reduces the load placed on the
brakes.
@) Tips
The brake lights turn on when the brakes are
applied automatically.

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.
The additional lane guidance assists the driver
with corrective steering in order to stay in the
lane. You can adjust if the adaptive cruise assist
will provide support with lane guidance
= page 135, Switching lane guidance on and off.
In stop-and-go traffic and in traffic jams, the ve-
hicle may brake to a full stop and then may also
start driving again automatically under certain
conditions.

tive control can adjust the speed based on traffic

Fig. 92 Example: driving into a curve
In some situations, the adaptive cruise assist
function is limited and you must assume control
of the vehicle when necessary, for example by ap-
plying the brakes.
— If a vehicle that was already detected @ turns
or changes lanes, the adaptive cruise assist will
react to the vehicle ahead of it @).
— When driving into a curve > fig. 92 and out of a
curve, the adaptive cruise assist may react to a
vehicle in the adjacent lane and apply the
brakes. You can override the system by pressing
the accelerator pedal briefly.
— The adaptive cruise assist works with the vari-
ous sensors and cameras in the vehicle.
Vehicles can only be detected once they are
within the area and range covered by the sen-
sors > page 116, fig. 81.
— When driving around tight curves, a vehicle
driving ahead that was previously detected may
no longer be detected, and the adaptive cruise
assist may accelerate unexpectedly.
— The adaptive cruise assist does not react toa
stationary vehicle in the same lane if the sys-
tem expects that you can easily drive around
the stationary vehicle by turning the steering
wheel.
— The adaptive cruise assist may not react to sta-
tionary obstacles, such as the end of a traffic
jam, especially at high speeds.
— The adaptive cruise assist has a limited ability
to detect vehicles that are a short distance
ahead, off to the side of your vehicle, or moving
into your lane.
— Objects that are difficult to detect, such as mo-
torcycles, vehicles with high ground clearance,
or vehicles with an overhanging load, may be
detected late or not detected at all.

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