Doors and windows
42Doors and windowsCentral locking systemDescriptionThe vehicle can be locked and unlocked via the central locking
system. You can use any of the following:•
Remote control key ⇒page 47
•
Door handles in conjunction with advanced key* ⇒page 47
•
Lock on driver's door ⇒page 48
•
Interior central locking switch ⇒page 49
Unlocking one side of the vehicle only
When you lock the vehicle, the central locking system will lock the
doors and the boot lid. When you unlock the vehicle, the central
locking system will unlock either the driver's door only, or all the
locks on the vehicle, depending on the setting you have selected on
the sound system or MMI* ⇒page 50 .
Automatic locking function (Auto Lock)
The Auto Lock function locks the doors and the boot lid when the
vehicle exceeds a speed of about 15 km/h.
The vehicle is unlocked again when the ignition key is removed.
Alternatively, the vehicle can al so be unlocked via the central
locking switch or by pulling one of the inside door handles. The Auto
Lock function can be switched on and off on the sound system or
MMI* ⇒page 50 .
In the event of an accident in which the airbags inflate, the doors
will be automatically unlocked to facilitate access and assistance.
Deadlock mechanism
The central locking system is combined with a deadlock mecha-
nism. Once the vehicle has been locked from the outside, the door handles on the inside are deactivated. This makes it more difficult
to break into the vehicle.
Anti-theft alarm system*
If the anti-theft alarm system senses interference with the vehicle it
triggers an audible and visible alarm.
The anti-theft alarm system switches on automatically when the
vehicle is locked. It switches off automatically if you unlock the
vehicle using the
remote control.
If you unlock the vehicle by inserting the key in the driver's door, the
ignition must be switched on within 15 seconds, otherwise the
alarm will be triggered. On some export versions, the alarm is trig-
gered immediately when you open a door.
To deactivate the alarm, press th e unlock button on the remote
control key or switch on the ignition . The alarm will also switch itself
off when it comes to the end of its cycle.
Switch off the interior monitor and tow-away protection if you wish
to prevent the alarm from being triggered accidentally ⇒page 50 .
Turn signals
The turn signals will flash twice when the vehicle is unlocked and
once when the vehicle is locked. If the turn signals do not flash, one
of the doors, the bonnet or the boot lid is still open.
Accidental lock-out
The central locking system prevents you from being locked out of
the vehicle in the following situations:
•
When the driver's door is open, it cannot be locked together with
the other doors by pressing the central locking switch and then
closing the door ⇒ page 49.
•
On vehicles with advanced key*, the boot lid will be released
again automatically if the remote co ntrol key that was last in use is
left inside the boot when the boot lid is closed ⇒page 51 .

Technical data
To prevent yourself from being locked out, do not lock the vehicle
with the remote control key
before closing the doors or boot lid. If
you accidentally press the locking button on your remote control
key when any of the doors (except for the driver's door) are open,
then put the key down inside the ca r and forget to take it with you
when you close the doors, you can still open the doors for about one
minute before the vehicle is locked.
WARNING
Do not leave anyone (especially chil dren) in the car if it is locked
from the outside and the deadlock mechanism is activated: the
doors and windows cannot then be opened from the inside.
Locked doors could delay assistance in an emergency, potentially
putting lives at risk.
Note
•
Never leave any valuable items in the vehicle unattended. Even a
locked vehicle is not a safe.
•
If the diode on the driver's wi ndow sill lights up for about
30 seconds when the vehicle is locked, the central locking system or
anti-theft alarm* is not working properly. Please have the malfunc-
tion repaired by an Audi dealer or qualified workshop.
•
The interior monitor of the anti-theft alarm* system will only
function as intended if the windows and the tilting panorama roof*
are closed.
Set of keys Remote control key
The remote control key will lock and unlock the car and start the
engine.
Spare key
The spare key is intended for temporary use only and should be
used only in an emergency. Keep it in a safe place and do not carry
it on the keyring.
Replacing a key
If you should lose a key, please contact an Audi dealer. Have the
remote control coding for that key deactivated. For this purpose you
should bring all available keys with you. It is also important to notify
your insurance company if a key has been lost.
Electronic immobiliser
The immobiliser is designed to prevent unauthorised persons from
driving the vehicle. If an uncoded key is used, SAFE will appear in
the mileage recorder display.
It may not be possible to start the engine with the key if there is
another ignition key from a different make of vehicle on the same
key ring.

Target speed
The target speed set by the driver is indicated by a red diode in the
speedometer.
If the speed setting is between two graduations on the speedom-
eter dial, the two closest diodes will both light up
⇒fig. 143.
It is only possible to set target speeds ranging from 30 to 200 km/h.
This speed range is illuminated slightly by the diodes on the speed-
ometer dial.
Indicator lamp (symbol)
•
No vehicle in front: The green indicator lamp ⇒ page 134,
fig. 144 shows that the adaptive crui se control system is in cruise
mode and that there is no vehicle in front. It maintains the stored
target speed.
•
Vehicle in front: The green indicator lamp shows that the
system has detected a vehicle in front. The speed is adapted to the
vehicle in front. The adaptive cruise control system accelerates and
brakes the vehicle automatically.
•
Driver intervention prompt: When the red indicator lamp
flashes , this is a warning for the driv er to intervene. The driver
has to brake the vehicle with the foot brake. This warning lamp will
always appear when the adaptive cruise control system alone is not
able to brake the vehicle sufficiently to maintain a safe distance to
a vehicle in front. An audible alarm (warning tone) will also sound
when the lamp starts to flash. For further information on the driver
intervention prompt ⇒page 138 .Note
•
If you exceed the target speed by using the accelerator, the
driver intervention prompt will not be accompanied by a warning
tone. The indicator lamp shown in the speedometer will also switch
off if the target speed is exceeded.

You can change the volume of the warning tone on the sound
system or MMI* ⇒ page 139, “Setting the warning tone volume and
driving program”.
