Locks with single control¹⁾

The single lock control allows you to simultaneously unlock or lock all doors, the fuel filler flap and the trunk.

You can open and close the car from the outside from the driver's or front passenger's door²⁾ / trunk, both with the key and with the remote radio control of the locks*



1) At the Audi service station, the single-control locking system can be equipped with an additional level of protection.

2) Not possible on vehicles with remote radio control locks*.

Unlocking the car

To unlock your vehicle from the doors, turn the key to the unlock position (left).

At the same time, all door lock buttons are pushed upward and the security alarm is turned off*.

To open the doors, lift the handle.

Locking the car

To lock your vehicle, turn the key inserted into the driver/front passenger door lock to the lock position (to the right). This locks the doors and trunk and also activates the security alarm*.

The readiness of the security alarm* to operate is confirmed by a short flashing of the direction indicators.

The interior lights in the door contact trigger position are switched off.

Warning: The driver's door cannot be locked when it is open. This can only be done after it is closed, and only for that door. This prevents the vehicle from being accidentally locked.

Warning: When locking, all door lock buttons must be pressed in. If any door button does not move, open it again and close it correctly.

Warning: The single lock control operates from the driver's door only after the door is closed.

Warning: If the single control fails, each lock can be used in the normal mode - up to the fuel filler cap. Emergency unlocking of the fuel filler cap is discussed in the subsection Refueling and emergency release of the fuel filler flap.

Heated door locks

The heating is switched on when the door handle is lifted briefly and the outside air temperature is below +5°C.



The warm-up time is set automatically depending on the actual temperature. The maximum warm-up time is about 50 seconds. You cannot increase the warm-up time by holding the handle in the upper position.

Once the warm-up cycle is complete, it can be resumed by lifting the door handle again.

Comfortable closing

When locking the vehicle from the driver's or front passenger's door, you can close the windows and the sliding/tilting roof panel* in the following sequence:

Keep the key in the lock position or press the remote control lock button* until all windows and the sliding/tilting roof panel are completely closed. Returning the key to the home position / releasing the transmitter button immediately stops the closing process.

When unlocking the vehicle with the key on the driver/front passenger side, you can open all windows at the same time by turning and holding the key in the unlock position or pressing the remote control unlock button* until the windows reach the desired position.

Security alarm*

Standard version

The security alarm is designed to prevent attempts to break into and steal a car. In the event of a break-in, the system starts to give sound and light alarm signals.

When the vehicle is locked, the system monitors the following potential attack targets:

• underhood space
• trunk
• doors
• audi radio system
• car interior
• ignition.

The alarm system is automatically activated when the vehicle is locked using the key inserted into the driver/front passenger door or trunk lock, or by remote control, and is deactivated when unlocked. The system enters guard mode approximately 30 seconds after the vehicle is locked.

The system confirms its readiness for operation, as well as the fact that the doors, hood and trunk are properly closed, by flashing the direction indicators when the car is locked.

If there is no light signal, check and, if necessary, close the doors, hood and trunk correctly. If you do this with the system already on, it will confirm the correct closing by flashing the turn signal lights.

Before leaving the vehicle, make sure all locking buttons are depressed and all windows, doors and sunroof panel* are closed.

Warning: When the car is locked from the trunk side and the driver's door is open, the alarm system is not activated. It is activated only after the driver's door is closed.

LEDs

After locking the vehicle, the LEDs next to the door lock button flash quickly for about 30 seconds and then slowly. This indicates that the alarm system, including interior monitoring, is armed. If the LEDs are constantly lit for about 30 seconds instead of flashing, this indicates a malfunction of the interior monitoring function.

Disabling the cabin control function

The interior control function switch is located on the door pillar.

1. Disable the interior monitoring function when locking the car and the possibility of the alarm being triggered as a result of animals or moving objects being in the car.

2. Open the driver's door.

3. Press the switch located on the door pillar. The diode in the switch lights up. Additionally, the LED located next to the door lock button lights up for about 3 seconds.

4. Lock the car.

5. The LEDs located next to the door locking buttons flash quickly for 3 seconds. After 30 seconds of locking, the LEDs start flashing slowly.

6. When the vehicle is subsequently locked, the interior monitoring function is automatically reset to operating mode.
