Opening and closing

Opening and closing
Central locking
You can lock and unlock the vehicle centrally. You
have the following options:
— Remote control key > page 27
— Sensors in the front door handles* > page 28
— Lock cylinder on the driver's door > page 30,
or
— Interior central locking switch > page 29
Turn signals
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.
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.
Selective door unlocking
The doors and luggage compartment lid will lock
when they close. You can set in the Infotainment
system whether only the driver's door or the en-
tire vehicle should be unlocked when unlocking
=> page 29.
Unintentionally locking yourself out
Only lock your vehicle when all of the doors and
the luggage compartment lid are closed and the
remote control key is not in the vehicle. This re-
duces the risk of locking yourself out accidental-
ly.
The following conditions prevent you from lock-
ing your remote control 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 convenience key* that was last used is in-
side the luggage compartment, the luggage
compartment lid will automatically open again
after closing it >©.
— If the last convenience key* that was used is de-
tected inside the vehicle, the vehicle cannot be
locked from the outside for a brief time > ©.

ZA WARNING
— If you leave the vehicle, switch the ignition
off and take the vehicle key with you. This
applies particularly when children remain in
the vehicle. Otherwise the children could
start the engine or operate electrical equip-
ment such as power windows.
— No one, especially children, should stay in
the vehicle when it is locked from the out-
side, because the windows can no longer be
opened from the inside > page 30. Locked
doors make it more difficult for emergency
workers to get into the vehicle, which puts
lives at risk.

CG) Note
Applies to: vehicles with convenience key
— If the convenience key that was last used is
detected inside the passenger compart-
ment, then the vehicle cannot be locked
from the outside using the sensor. Take the
convenience key with you and lock the vehi-
cle again. Otherwise, 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 plac-
ing 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
25
>

Opening and closing

the vehicle within a short time to remove
the vehicle key, then the vehicle will lock au-
tomatically. This prevents the vehicle from
being left unlocked for long periods of time.
The key will then be locked inside the vehi-
cle.
— If the convenience key* that was used last is
detected 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 convenience
key with you, or unauthorized people 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 lights up 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.
