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. 115 ©.
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. 115.
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. 116. 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. >

Night vision assist
Applies to: vehicles with night vision assist
Night vision assist helps you when it is dark by
using an infrared camera to monitor the area in
front of your vehicle, within the limits of the sys-
tem. It can display objects up to a distance of ap-
proximately 1000 feet (300 m).
Pedestrian and wild animals are detected by
measuring the temperature difference between
the object and the background. Pedestrians and
wild animals will not be detected if the tempera-
ture difference is too small. The pedestrian and
wild animal marking feature is deactivated at
temperatures above approximately 77 °F (25 °C)
and when it is light outside.
The thermal image detected by the camera is dis-
played in the instrument cluster. Warm areas
generally appear lighter and cold areas appear
darker.
The camera for the night vision assist @)
= page 156 is located in the vehicle's radiator
grille. Make sure the night vision camera is not
covered by stickers, deposits, or any other ob-
structions because this can impair the night vi-
sion assist function. Follow the information
about cleaning > page 309.

Driver assistance

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 174, 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.
Applies to: vehicles with efficiency assist: Predic-
tive control can adjust the speed based on traffic
and road conditions > page 169, Predictive con-
trol.

Fig. 125 Example: vehicle changing lanes and stationary
vehicle



Fig. 126 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.
— Ifa 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. 126 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 155, fig. 115.
— 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.

Driver assistance


ZA WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 154.
— The activated adaptive cruise assist is only
an assist system, and the driver is still re-
sponsible 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 adaptive cruise assist only if the
surrounding conditions permit it. Always
adapt your driving style to the current visu-
al, weather, road, and traffic conditions.
— Switch the adaptive cruise assist off tempo-
rarily when driving in turning lanes or high-
way exits. This prevents the vehicle from ac-
celerating to the stored speed when in these
situations.
— If you press the [SET|) button when driving
at speeds below 20 mph (30 km/h), then 20
mph (30 km/h) will be set because that is
the minimum speed that can be set. If no
vehicle is detected ahead of you, the vehicle
will accelerate up to that speed.


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.
— If you switch the ignition or the adaptive
cruise assist off, the stored speed is erased
for safety reasons.
— When the adaptive cruise assist is switched
on, the ESC and the ASR are switched on au-
tomatically.
— The system cannot be switched off if the
road exceeds the maximum possible grade
for safe operation.

ance

B8V-0692


Fig. 131 Turn signal lever: button for lane guidance and
lane departure warning (example)
Within the limits of the system, lane guidance
provides corrective steering to assist the driver
with keeping the vehicle in the center of the lane
as much as possible. This feature can be deacti-
vated.
Switching lane guidance on and off
Requirement: lane guidance must be preselected
in the MMI > page 178.
> Press the > fig. 131 button.
When adaptive cruise assist is actively regulating
and lane guidance is switched on, the system will
assist the driver with corrective steering.
Overview of displays and lane guidance
limitations
In the Driver assistance display, the awe indi-
cator light informs you if lane guidance is availa-
ble G0 > page 172, fig. 128.
If the Hi or WM indicator light turns on white on
at least one side, or the & indicator light turns
on white in the Driver assistance display, then
lane guidance is not active. This may be due to
the following reasons:
— The necessary lane marker lines have not been
detected (for example, in a construction zone
or because the lines are obstructed by snow,
dirt, water, or lighting)
— The lane is too narrow or too wide
— The curve is too narrow
— Visibility is obstructed by a rise or dip.

Steering intervention request
If no steering activity is detected or the steering
power is not sufficient, the driver steering inter-
vention 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. The system
will become inactive after a short time and will
only be active again later.
If the driver does not take over steering, adaptive
cruise assist will be canceled. If the vehicle is
equipped with emergency assist and it is ready to
function, it will be activated > page 190.

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

@ 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.
— It is recommended to only switch on lane
guidance on well-constructed roads.
— Certain settings are stored automatically in
the active personal profile.
—The & fig. 131 button switches lane guid-
ance availability and the lane departure
warning on or off simultaneously, if lane
guidance is preset in the adaptive cruise as-
sist settings.
Setting the distance
Applies to: vehicles with adaptive cruise assist

B4M-0234



Fig. 132 Operating lever: setting the distance
If you adjust the speed, you must also change the
time gap to the vehicle driving ahead. The higher
the speed, the greater the distance that is need-
ed.
> Tap the rocker switch to display the distance
that is currently set.
> To increase or decrease the distance in incre-
ments, tap the switch again toward G) or ().
The newly-set distance will be shown briefly, for
example with the indicator light. In the Driv-
er assistance display, a graphic display is shown
instead of the indicator lights > page 172,

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
system due to vehicles traveling beside you or
due to approaching vehicles. This will attempt to
keep your vehicle in the lane.
