Stowing and using
attachments from the Audi Genuine Accesso-
ries program are recommended.
— Make sure the roof rack is mounted on the vehi-
cle only at the specified locations > fig. 90.
— Note the permitted axle load, permitted total
weight, and permitted roof load of your vehicle
=> page 298. The roof load is the total of the
weight of the roof rack, the attachments and
the cargo you are carrying. However, you must
also note the permitted load of the carrier sys-
tem being used.
ZA\ WARNING
— Follow the installation instructions provided
with the roof rack system. If you do not se-
cure the roof rack system and objects on the
roof correctly, they could come loose from
the vehicle and cause an accident.
— The risk of an accident increases when using
a roof rack system, because it changes the
driving characteristics by shifting the center
of gravity and/or the increasing the surface
area exposed to wind. You may need to
adapt your driving style and speed to the
current conditions. We recommend that you
do not drive faster than 80 mph (130
km/h).
— Distribute the cargo evenly on the roof rack
and do not exceed the maximum width or
the maximum total roof load weight.
— Before every trip, all bolts and connections
on the roof rack must be checked. Tighten
them if necessary and recheck them regular-
ly. If you do not do this, there is a higher risk
of
the roof rack or the attachments loosen-
ing or falling off.
@) Note
— If you use other roof luggage rack systems
or do not install the roof racks as specified,
then any damage to the vehicle is not cov-
ered by the warranty. Carefully follow the
assembly and installation instructions in-
cluded with the roof rack carrier system.
—To reduce the risk of damage, you must re-
move the roof rack and attachment before
taking your vehicle through an automatic
car wash.

— Make sure that the luggage compartment
lid and the panoramic glass roof* do not
come into contact with objects on the roof
when they are open.
@) For the sake of the environment
Energy usage will increase because of the in-
creased wind resistance. Remove the roof rack
when you are no Longer using it.

Fig. 123 Diagram: driving situations and displays in the ex-
terior mirror (example)
General information
Side assist monitors the blind spot and traffic in
the adjacent lanes behind the vehicle. Within sys-
tem limits, side assist can detect traffic that is
approaching from behind and provide a warning
when you are changing lanes and turning. The
system uses the data from the radar sensors at
the rear corners of the vehicle.
The side assist is active at walking speeds and
higher. If an object that is classified as critical is
approaching, the display in the exterior mirror @)
on the corresponding side of the vehicle will light
up.
Driving situations
The system can provide warnings about the fol-
lowing risks:
@ Approaching vehicles: a vehicle may be clas-
sified as critical in some cases, even if it is
150
farther away. The faster a vehicle ap-
proaches, the sooner the display will turn on.
Vehicles traveling in the same direction: the
display will turn on if vehicles traveling in the
same direction as your vehicle are classified
as critical. The side assist warns you of all de-
tected vehicles when they are in the “blind
spot” or before they reach that point.
@® Vehicles you are passing: the display only
turns on if you slowly pass a detected vehicle
(difference in speed between the two vehicles
is less than 9 mph (15 km/h)). There is no
display if you pass a vehicle more quickly.
Information stage
At the information level, the side assist informs
you of detected objects that are classified as criti-
cal. This is even possible when your vehicle is sta-
tionary and the turn signal is turned on, so that
the system can also assist you when turning.
From speeds of approximately 6 mph (10 km/h)
and higher, the system will warn you of detected
objects that are classified as critical, even if the
turn signal is not turned on.
The display remains dim in the information stage
so that you are not distracted while looking for-
ward.
Warning stage
If you activate a turn signal and the display flash-
es brightly, side assist is warning about objects
that have been classified as critical.
Depending on the vehicle equipment and other
driver assistance systems, the display may also
flash if you have not activated a turn signal. If
you are approaching a detected lane marker line
and it appears you will be leaving the lane, the
display will warn you about detected vehicles
that are classified as critical. You can also be
warned with corrective steering > page 144,
Lane departure warning.
Detection range
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In some situations, the display
may turn on even though there is no vehicle >
Parking and maneuvering
@ You should stop driving in reverse when the
red orientation line touches the edge of an
object, at the latest.
Trailer view
Applies to: vehicles with trailer view
The trailer view > fig. 133 assists you in position-
ing the vehicle in front of a trailer.
— Applies to: vehicles with peripheral cameras:
Switch to the Rear view G) > page 161,
fig. 134.
— Select Trailer view in the upper display when
the parking aid is active |].
Now you can position your vehicle in front of the
trailer. The orange orientation line ©) ° fig. 133
indicates the expected path toward the trailer
hitch. Use the blue markings © to help you esti-
mate the distance to the trailer hitch. Each mark-
ing represents approximately 1 foot (0.30 me-
ters). The width of the blue surface represents
the maximum steering wheel angle.
Symbols
If $2/€9/< is displayed and the display area
represented by that symbol is not available, then
the camera on the that side is not available. The
power exterior mirrors may have been folded in
or a door or the luggage compartment lid may
have been opened.
If # is displayed, there is a system malfunction
and the display area represented by that symbol
is not available. The camera is not working in this
area.
If Nvis displayed, the respective ultrasonic sensor
is icy or dirty. Clean the area in front of the sen-
sors > page 120.
If one of the symbols continues to be displayed,
drive immediately to an authorized Audi dealer or
authorized Audi Service Facility to have the mal-
function repaired.

Z\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 118.
— 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 detect-
ed at all. Always monitor the traffic and the
vehicle's surroundings directly and do not
become distracted.
@) Note
— The orange orientation lines @) show the di-
rection the rear of the vehicle will be travel-
ing, based on the steering wheel angle. The
front of the vehicle swings out more than
the rear of the vehicle. Maintain plenty of
distance so that an exterior mirror or a cor-
ner of the vehicle does not collide with any
obstacles.
— Keep enough distance from the curb to
avoid damage to the rims.
— Only use the images provided by the camera
on the rear of the vehicle when the luggage
compartment lid is completely closed. Make
sure any objects you may have mounted on
the luggage compartment lid do not block
the rearview camera.
@ Tips
— Applies to vehicles with air suspension: The
accuracy of the orientation lines and blue
surfaces on the camera display decreases
when the vehicle is raised or lowered with
the air suspension.
— There is no rear distance warning when trail-
er mode is detected. The front sensors re-
main activated. The visual display switches
to trailer mode. The rearview camera image
will not show the orientation lines and the
blue surfaces. There is no guarantee the
functions will be deactivated when using a
retrofitted trailer hitch.
