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.

Door unlocking
—If you select All, all doors and the luggage
compartment lid will be unlocked when unlock-
ing the vehicle.
— If you select Driver's door, only the driver's
door will be unlocked. To unlock all doors and
the luggage compartment lid, press the ( but-
ton on the vehicle key twice. In vehicles with a
convenience key*, only the driver's door will un-
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
press the &@ button.
Long press to open windows
You can select if all windows and the panoramic
glass roof* should open using the vehicle key
= page 46, Convenience opening and closing. If
you press and hold the fj button on the vehicle
key, all of the windows and the panoramic glass
roof* will close.
Disable rear lid handle
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.

ly fold in when locking.
