Central locking
(ee emul ela)
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
system: No one, especially children, should
stay in the vehicle when it is locked from the
outside, because the windows can no longer
be opened from the inside > page 46, Anti-
theft alarm system. Locked doors make it
more difficult for emergency workers to en-
ter 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 44. 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 48 and > page 111.
Power closing*
When closing a door or the luggage compart-
ment lid, you only have to let it fall lightly into
the latch. It then closes automatically > A.
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 > ©.

Opening and closing


ZA WARNING
Follow the safety precautions > page 43.

Z\ WARNING
Applies to: vehicles with power closing function
—To reduce the risk of injury, make sure that
the area where the door is closing is clear
during the closing process.
— The closing process can be stopped at any
time by pulling on the outer or inner door
handle.

@) Note
— 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 lock the vehicle using the button on
the vehicle key with the front passenger's
or rear door open while accidentally placing
the key in the passenger compartment and
closing the door, the vehicle will not lock.
The turn signals will flash several times to
indicate this. If you do not open the vehicle
to remove the vehicle key within a brief peri-
od, then the vehicle will lock automatically.
This prevents the vehicle from being left un-
locked for long periods of time. The key will
then be locked inside the vehicle.
— If the vehicle key that was used last is de-
tected inside the luggage compartment, it
will not be possible to lock the luggage
compartment and the luggage compart-
ment lid will open. 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.
G) 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
44
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.

preferences. The settings depend on the vehicle
equipment.
