Driver assistance


— The display may not appear on time when
vehicles are approaching or being passed
very quickly.


— If the window glass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be incor-
rect.
— The coverage areas of the sensors > fig. 120
are diagrams and do not represent a true-
to-scale image of the sensor ranges.
— The system complies with United States FCC
regulations and ISED regulations
=> page 284.
OTe eed
Applies to: vehicles with side assist

You can adjust the side assist to your preferences.
The settings depend on the vehicle equipment.
> Applies to: MMI: Select on the home screen:
VEHICLE > Driver assistance > Side assist.
Possible settings:
The system can be switched on and off. If the sys-
tem is switched on, the displays in the exterior
mirrors will turn on briefly each time the ignition
is switched on.
Brightness - Change the brightness only when
side assist is switched on, so that the selected
setting can be checked in the exterior mirror dis-
plays. Adjust the brightness to a level where the
display will not interfere with your view ahead.
Because the display brightness automatically
adapts to the ambient light, it may have already
been adjusted to the highest or lowest setting
during the automatic adaptation.
@ Tips
— If you switch side assist on or off, the exit
warning will also switch on or off.
— Certain settings are automatically stored
and assigned to the remote control key be-
ing used.

Information about the services and the corre-
sponding app was accurate at the time this man-
ual was printed. The scope of services depends
on the country and equipment. There may be
changes over the service life of the vehicle.

ZA WARNING
— Always follow the information found in > AA
in General information on page 173.
— Driver messages, text messages, and illumi-
nated warning and indicator lights in the ve-
hicle always take priority over information
from the Audi connect services. The infor-
mation displayed by the Audi connect serv-
ices should not cause you to take safety
risks. This can result in the vehicle breaking
down in traffic and to serious injuries or ac-
cidents.
G) Tips
— Accessing specific data or controlling func-
tions remotely depends on the charge level
of the vehicle battery. Therefore, these
functions only have limited availability after
switching off the ignition.

— An eSIM card establishes the Internet con-
nection for Audi connect vehicle control
services. The costs for this are included in
the price of Audi connect vehicle control
services. The cell phone network, for exam-
ple, must be available to use these services.
