Users
(eT e e eeu)
Applies to: vehicles with personalized user settings
Depending on vehicle equipment and your coun-
try, your vehicle may be able to manage various
users in the MMI. Each user will be assigned the
settings that they last used.
Before you begin driving, you can select a user in
the MMI and load personalized Infotainment and
vehicle settings.
Possible users in the MMI:
— myAudi user: as a myAudi user, you can use
Audi connect services that require a myAudi ac-
count. Certain settings are transferred online to
your myAudi account. If you log into your
myAudi account in another vehicle, you can
load your settings in the other vehicle.
— Local user: as a local user, you can only store
settings in the current vehicle. Your settings
cannot be transferred to other vehicles. Audi
connect services that can only be used with a
myAudi account will not be available.
— Guest: as a guest, you can store settings in the
vehicle without changing the settings for other
users. Audi recommends only using the guest
user temporarily, because settings can be over-
written by other users.
Depending on vehicle equipment, the following
options may be used to detect the active user so
that the user settings can be loaded automatical-
ly before you start driving.
— Vehicle key
Requirement: the driver's door has been opened.
The detected user must be shown in the MMI.
Confirm the user shown, select another user
= page 30, or add another user > page 30.

ZA\ WARNING
It may not be possible to load Infotainment
and vehicle settings, or they may only load
partially. The driver is always responsible for
the Infotainment and vehicle settings in order
to reduce the risk of an accident.

G) Tips
— Certain Infotainment and vehicle settings
(such as mirrors, last radio stations) may be
stored, depending on vehicle equipment.
You can find additional information in the
MMI. Select on the home screen: SETTINGS
> General > Legal notes > About Audi con-
nect.
— Applies to: myAudi users: The stored set-
tings can only be transferred to vehicles
that are capable of receiving the transmit-
ted information. There may be restrictions
that prevent this, particularly in other coun-
tries.
— Applies to: myAudi users: The settings can
only be transferred and loaded when there
is coverage from the applicable mobile
phone service provider.
— Applies to: myAudi users with PIN protec-
tion switched on: If the MMI displays a de-
tected user but you simply start driving or
wait without entering the 4-digit PIN, then
the guest user will be selected. Some set-
tings for the detected myAudi user will be
transferred to the guest user.

General information
Z\ WARNING
— If you leave the vehicle, switch the ignition
off and take the key with you. This applies
particularly when children remain in the ve-
hicle. Otherwise, children could start the ve-
hicle or operate electrical equipment (such
as power windows), which increases the risk
of an accident.

— Applies to vehicles with anti-theft alarm sys-
tem: When the vehicle is locked from the
outside, no one - especially children - should
remain in the vehicle, because the windows
can no longer open from the inside
=> page 36, Anti-theft alarm system.
Locked doors make it more difficult for
emergency workers to enter the vehicle,
which puts lives at risk.
All doors and the luggage compartment lid can
be centrally unlocked and locked at once. You can
select in the MMI if the entire vehicle or only the
driver's door should unlock when unlocking the
vehicle > page 34. The turn signals flash twice
when you unlock the vehicle and flash once when
you lock the vehicle. If they do not flash when
locking, check if all doors and lids are closed.

Depending on the vehicle equipment, you may
have different options for centrally unlocking and
locking your vehicle.

Vehicle key
The term “vehicle key” refers to the remote con-
trol key or convenience key*. The convenience
key* is a remote control key with special func-
tions > page 38 and > page 95.
Automatic locking
If you unlock the vehicle but then do not open
any of the doors, the luggage compartment, or
the hood within a short period time, the vehicle
locks again automatically. This feature prevents
the vehicle from being accidentally left unlocked
for a long period of time.
Automatic locking (Auto Lock)
The Auto Lock function locks all doors and the
luggage compartment lid once the speed has ex-
ceeded approximately 9 mph (15 km/h). The ve-
hicle will unlock again if the unlock function in
the central locking switch is pressed, the “P” gear
is engaged, or the ignition is switched off.
You can open the doors individually from the in-
side by pulling the door handle one time. To open
the rear doors individually, you must pull the
door handle twice.
In the event of a crash with airbag deployment,
the doors will also automatically unlock to allow
access to the vehicle.
Unintentionally locking yourself out
Only lock your vehicle when all of the doors and
the luggage compartment lid are closed and
there is no key in the vehicle. This reduces the
risk of locking yourself out accidentally.
The following features help to reduce the risk of
locking your vehicle key in the vehicle:
— If the driver's door is open, the vehicle cannot
be locked by pressing the & button on the re-
mote control key or by touching the locking
sensor* on a door.
— If the vehicle key that was used most recently is
inside the luggage compartment, the luggage
compartment lid will automatically open again
after it closes > ©.
— If the vehicle key that was last used is detected
inside the vehicle, then the vehicle cannot be
locked from the outside > ©.

ZA\ WARNING
Observe the safety precautions > page 33. >

Opening and closing

@) Note
The following applies when locking the vehi-
cle:
— If the vehicle key that was last used is de-
tected inside the passenger compartment,
then the vehicle cannot be locked from the
outside using the sensor. Take the vehicle
key with you and lock the vehicle again. Oth-
erwise, the vehicle will not be protected
against unauthorized access.
— If you try to lock the vehicle using the but-
ton on the vehicle key while the front pas-
senger's or rear door is open, and you acci-
dentally place the vehicle key inside the pas-
senger compartment and close the door,
the vehicle will lock at first. But if the key-
less system detects a vehicle key inside the
vehicle after it locks, then the vehicle will
unlock again. The turn signals will flash sev-
eral times to indicate this. If you do not
open the vehicle to remove the vehicle key
within a brief period, then the vehicle will
lock automatically. This prevents the vehicle
from being left unlocked for long periods of
time. The vehicle key will then be locked in-
side the vehicle.
— If the luggage compartment lid closes and
the system detects that the last vehicle key
that was used is inside the luggage com-
partment, then the luggage compartment
lid will open again. The turn signals will
flash several times to indicate this. The
doors will lock. Always take the vehicle key
with you, or unauthorized persons may be
able to enter the vehicle.
@) Tips
— Do not leave valuables unattended in the ve-
hicle. A locked vehicle is not a safe!
—The LED in the driver's door rail blinks when
you lock the vehicle. If the LED turns on for
approximately 30 seconds after locking,
there is a malfunction in the central locking
system. Have the problem corrected by an
authorized Audi dealer or authorized Audi
Service Facility.

lock when you pull the driver's door handle. If
you pull another door handle, the entire vehicle
will be unlocked.
The entire vehicle will always be locked f you

You can select if the luggage compartment lid
can open with the handle. If you activate this
function, the luggage compartment lid can only
be opened with the << or 4s button on the vehi-
cle key or in the driver's door. In vehicles with a
convenience key*, you can still open the luggage
compartment lid using the handle if an author-
ized convenience key is detected > page 40.
