Audi A4: Central locking

General information

WARNING

• If you leave the vehicle, switch the ignition off and take the key with you. This applies particularly when children remain in the vehicle.

  Otherwise, children could start the vehicle or operate electrical equipment (such as power windows), which increases the risk of an accident.

• Applies to: vehicles with anti-theft alarm system: When the vehicle is locked from the outside, no one, especially children, should remain in the vehicle, because the windows can no longer open from the inside, Anti-theft alarm system.

  Locked doors make it more difficult for emergency workers to enter the vehicle, which puts lives at risk.

• Applies to: child safety lock: No one, especially children, should stay in the vehicle when the child safety lock is activated, because the windows can no longer be opened from the inside. This increases the risk of fatal injury.

Description

All doors and the luggage compartment lid can be centrally unlocked and locked at once. You can select in the MMI if the entire vehicle or only the driver's door should unlock when unlocking the vehicle. 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.

Depending on the vehicle equipment, you may have different options for centrally unlocking and locking your vehicle.

• Vehicle key
• Sensors in the door handles
• Lock cylinder in the driver's door
• Interior central locking switch

Vehicle key

The term "vehicle key" refers to the remote control key or convenience key*. The convenience key* is a remote control key with special functions.

Automatic locking

If you unlock the vehicle but then do not open any of the doors, the luggage compartment, or the hood within a short period time, the vehicle locks again automatically. This feature prevents the vehicle from being accidentally left unlocked for a long period of time.

Automatic locking (Auto Lock)

The Auto Lock function locks all doors and the luggage compartment lid once the speed has exceeded approximately 9 mph (15 km/h). The vehicle will unlock again if the unlock function in the central locking switch is pressed, the "P" selector lever position is selected, or the ignition is switched off.

You can open the doors individually from the inside 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.

Unintentionally locking yourself out

Only lock your vehicle when all of the doors and the luggage compartment lid are closed and there is no key in the vehicle. This reduces the risk of locking yourself out accidentally.

The following features help to reduce the risk of locking your vehicle key in the vehicle:

• If the driver's door is open, the vehicle cannot be locked by pressing the button on the remote control key or by touching the locking sensor* on a door.
• If the vehicle key that was used most recently is inside the luggage compartment, the luggage compartment lid will automatically open again after it closes.
• If the vehicle key that was last used is detected inside the vehicle, then the vehicle cannot be locked from the outside.

WARNING

Observe the safety precautions.

Note

The following applies when locking the vehicle:

• If the vehicle key that was last used is detected inside the passenger compartment, then the vehicle cannot be locked from the outside using the sensor. Take the vehicle key with you and lock the vehicle again. Otherwise, the vehicle will not be protected against unauthorized access.
• Applies to: vehicles with convenience key: If you try to lock the vehicle using the button on the vehicle key while the front passenger's or rear door is open, and you accidentally place the vehicle key inside the passenger compartment and close the door, the vehicle will lock at first. But if the keyless system detects a vehicle key inside the vehicle after it locks, then the vehicle will unlock again. The turn signals will flash several times and a warning tone!) will sound to indicate this. If you do not open the vehicle to remove the vehicle key within a brief period, then the vehicle will lock automatically. This prevents the vehicle from being left unlocked for long periods of time. The vehicle key will then be locked inside the vehicle.
• Applies to: vehicles with convenience key: If the luggage compartment lid closes and the system detects that the last vehicle key that was used is inside the luggage compartment, then the luggage compartment lid will open again. The turn signals will flash several times and a warning tone!) will sound to indicate this. The doors will lock.

  Always take the vehicle key with you, or unauthorized persons may be able to enter the vehicle.

Tips

• Do not leave valuables unattended in the vehicle.

  A locked vehicle is not a safe!

• The LED in the driver's door rail blinks when you lock the vehicle. If the LED turns on 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.
