ZA WARNING
— Always follow the information found in > AA
in General information on page 192.
— 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.


@) 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.
Applies to: vehicles with Audi connect vehicle control
Create a myAudi account by registering in the
myAudi app or at my.audi.com, depending on
your country.
>» Set the key user > page 32.
> Install the myAudi app on your mobile device
and log in with your access information.
@) Tips
Some services require you to enter a 4-digit
PIN that you set up during registration.

ment, the following functions may be available:
Wi-Fi
When the function is switched on, the MMI's Wi-
Fi hotspot is active and Wi-Fi devices can be con-
nected to the hotspot.
Wi-Fi hotspot settings
The Wi-Fi connection between the MMI and your
Wi-Fi device is encrypted. You can change the fol-
lowing information if needed.
— Access point (SSID): name of the Wi-Fi hot-
spot.
— Password: an initial password was set at the
factory in the MMI. Audi recommends changing
the initial password. Only use secure passwords
that conform to the general guidelines for se-
cure passwords. For more information, refer to
reputable and current sources on password se-
curity.
Allow data connection through Wi-Fi
When the function is switched on, mobile devices
can use the Internet connection through the Wi-
Fi hotspot. A data plan is needed to do this.
