Doors and central locking button
Introduction
This chapter contains information on the followingsubjects:
⇒ Indicator lamp in the driver door 
⇒ Automatic locking and unlocking 
⇒ Central locking button 
⇒ Opening and closing the driver door manually 
⇒ Manually closing the front passenger door and rear doors 
⇒ Childproof lock 
⇒ SAFELOCK 
⇒ Troubleshooting 
If the vehicle key or central locking fails, the doors can be locked manually and, in some cases, also
unlocked manually.
The central locking system enables you to centrally lock and unlock all the doors, the boot lid and
the tank flap of the vehicle.

With some equipment levels, the vehicle may have a SAFELOCK mechanism.
SAFELOCK deactivates the door release levers if the vehicle has been locked. This makes it more
difficult to break into the vehicle. The doors can no longer be opened from the inside ⇒ .
Press the button on the vehicle key once.
Press the button on the vehicle key twice in quick succession.
Vehicles with the Keyless Access locking and starting system: touch the sensor on the outside of the
door handle twice⇒ Unlocking or locking the vehicle with Keyless Access .
OR: press the central locking button in the driver door once ⇒ Central locking button .
There may be an indication of the activated SAFELOCK in the display of the instrument cluster
(SAFELOCK).
Deactivating SAFELOCK
Switch on the ignition.
OR: deactivate interior monitoring and the anti-tow alarm ⇒ Temporarily switching off the interior
monitoring system and anti-tow alarm .
Before locking the vehicle, temporarily deactivate the interior monitoring and the anti-tow alarm in
the Vehicle Settings menu in the Infotainment system ⇒ Infotainment system controls and displays .
The following applies when SAFELOCK is deactivated:
The interior monitoring and the anti-tow alarm are activated and deactivated in the Vehicle settings
menu in the Infotainment system ⇒ Infotainment system controls and displays .

WARNING
Careless or unsupervised use of SAFELOCK can cause serious injuries.
Never leave other persons in the vehicle if the vehicle has been locked using the vehicle key. The
doors can no longer be opened from the inside once SAFELOCK is activated.

If you unlock the driver door mechanically using the vehicle key, only the driver door is unlocked,
and not the whole vehicle. The doors are released (but not unlocked) and the central locking button
is activated only when the ignition is switched on.
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Indicator lamp lights up continuously
The red LED in the vehicle door flashes at short intervals and then lights up continuously.

There is a fault in the locking system.
Go to a qualified workshop. Volkswagen recommends using a Volkswagen dealership for this
purpose.
Turn signals do not flash
If the turn signals do not flash as confirmation when the vehicle is locked:
At least one of the doors or the boot lid is not closed.
OR: convenience closing is in progress and not all windows and the glass roof have been closed.
Vehicle locks itself automatically
The vehicle will lock itself again automatically after approx. 45 seconds if one of the following
conditions applies:
The vehicle has been unlocked but not opened.
The ignition has not been switched on.
The boot lid has not been opened.
The vehicle has been unlocked using the lock cylinder.
The vehicle has been locked using the central locking button in the vehicle interior.
Response when locking the vehicle with a second vehicle key
Keyless Access: the vehicle key located inside the vehicle will be blocked from starting the engine if
the vehicle has been locked from the outside using a second vehicle key. Press the button on the
vehicle key in the vehicle interior to enable it to start the engine ⇒ Starting and stopping the
engine .
Locking the vehicle after airbags have been triggered
The entire vehicle is unlocked if the airbags are activated in an accident. Depending on the extent of
the damage, the vehicle can be locked as follows after an accident:
Switch the ignition off and then back on again.
Automatic deactivation of the sensors
The vehicle is not unlocked or locked for an extended period.
A sensor has been triggered an excessive number of times.
Reactivating the sensors:
Unlock the vehicle with the button in the vehicle key.

NOTICE

Please note that the sensors in the door handles can be activated by a powerful jet of water or
steam if a valid vehicle key is simultaneously within the operating range. If at least one window is
open and sensor surfaces on the door handles are continuously activated, all windows will close. All
windows could open if the jet of water or steam is moved away from the door handle sensors briefly
and then moved back again ⇒  .

It may not be possible to lock or unlock the vehicle using the Keyless Access if the 12-volt vehicle
battery or button cell in the vehicle key is weak or discharged. The vehicle can be locked or unlocked
manually ⇒  .

If there is no valid vehicle key in the vehicle or if it is not detected, a corresponding message will be
shown on the instrument cluster display. This may occur if the vehicle key is exposed to interference
from another radio signal or is covered by another item, e.g. an aluminium case ⇒ Starting and
stopping the engine .
Anti-theft alarm
Depending on the vehicle equipment level, the vehicle may have an anti-theft alarm.
The anti-theft alarm is activated automatically when the vehicle is locked using the vehicle key.
The anti-theft alarm outputs acoustic and visual warning signals for up to five minutes.
When does the system trigger an alarm?
If a door is opened.
If the bonnet is opened.
If the boot lid is opened.
If the ignition is switched on with a valid vehicle key. (The alarm may sound briefly.)
If the 12-volt vehicle battery is disconnected.
If there is movement inside the vehicle (in vehicles with interior monitoring) ⇒ Interior monitoring
system and anti-tow alarm .
If the vehicle is lifted or towed (vehicles with anti-tow alarm) ⇒ Interior monitoring system and anti-
tow alarm .
If the vehicle is transported on a car ferry or by rail (vehicles with anti-tow alarm or interior
monitoring) ⇒ Interior monitoring system and anti-tow alarm .
If a trailer that is connected to the anti-theft alarm system is removed ⇒ Trailer towing .
Switching off the alarm
Unlock the vehicle using the unlocking button on the vehicle key.

OR: switch on the ignition using a valid vehicle key. A short alarm lasting around one second may
sound.
On vehicles with Keyless Access: grip the door handle ⇒ Unlocking or locking the vehicle with
Keyless Access .

The anti-theft alarm will not function correctly if the 12-volt vehicle battery is weak or discharged.
