The Audi A3 can be locked and unlocked via the central locking system. You can use the following (depending on the equipment on your Audi A3):
Unlocking one side of the Audi A3 only
When you lock the Audi A3, the central locking system will lock the doors and the boot lid. When you unlock the Audi A3, the central locking system will unlock either the driver's door only, or all the locks on the Audi A3, depending on the setting you have selected in the MMI* ►Link.
Automatic locking function (Auto Lock)
The Auto Lock function locks the doors and the boot lid when the Audi A3 exceeds a speed of about 15 km/h.
The Audi A3 is unlocked again when the ignition key is removed. Alternatively, the Audi A3 can also 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* ►Link.
In the event of an accident in which the airbags inflate, the doors will be automatically unlocked to facilitate access and assistance.
Turn signals
The turn signals will flash twice when the Audi A3 is unlocked and once when the Audi A3 is locked.
If the turn signals do not flash, one of the doors, the bonnet or the boot lid is still open. On Audi A3s with the convenience key, the ignition may still be switched on.
Accidental lock-out
The central locking system prevents you from being locked out of the Audi A3 in the following situations:
- When the driver's door is open, the Audi A3 will not be locked if you press the central locking switch and then close the door ►Link.
- On Audi A3s with convenience key*, the boot lid will be released again automatically if the key that was last in use is left inside the boot when the boot lid is closed.
To prevent yourself from being locked out, do not lock the Audi A3 with the remote control key/convenience key* until all of the doors and the boot lid are closed.
Note
- Never leave any valuable items in the Audi A3 unattended. Even a locked Audi A3 is not a safe.
- When you lock the Audi A3, the LED on the driver's window sill flashes. If the LED is still on about 30 seconds after the Audi A3 is locked, the central locking system is not working properly. You should have the malfunction repaired by a qualified workshop.
