Central Locking
Description
You can lock and unlock the veh icle centrally . You
have the following choices:
- Remote control key¢
page 40,
-Sensors in the door handles * ¢ page 40
- Lock cylinder on the driver's door¢ page 42,
or
- Interior central locking switch ¢
page 41.
Turn signals
The turn s ignals flash twice when you unlock the
veh icle and flash once when you lock the veh icle.
If they do not flash, then one of the doors, the
rear lid or the hood is not closed.
Automatic locking (Auto Lock)
The Auto Lock funct ion locks all doors and the
luggage compartment lid once the speed has ex­
ceeded approximately 9 mph (15 km/h).
The vehicle can be unlocked if the opening func­
tion in the central locking system sw itch is used
or one of the door handles is pulled.
In the event of a crash with airbag deployment,
the doors will a lso automat ically 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 41.
Unintentionally locking yourself out

locking switch, the vehicle will not lock if a door
is open ¢
page 41.
-On vehicles with a convenience key*, the lug­
gage compartment lid unlocks again after clos­
ing if the most recently used key is in the lug­
gage compartment. The emergency flashers blink four times.
Do not lock your vehicle with the remote control
key or convenience key* until all doors and the
luggage compartment lid are closed. This helps
to prevent you from locking yourself out acciden­
tally .
A WARNING
-
-When you lock your vehicle from outs ide,
nobody -espec ially children -should rema in
inside the vehicle. Remember, when you
lock the vehicle from the outside the win­
dows cannot be opened from the inside .
- When you leave the vehicle, always take the

sengers (children, for examp le) from acci­
dentally being locked in the vehicle should
they accidentally press the power locking
switch in the doors.
- Do not leave children inside the vehicle un­
supervised. In an emergency it would be im­
possible to open the doors from the outside
without the key.
(D 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 repaired by an
authorized Audi dealer or authorized Audi
Service Facility.
