The anti-theft alarm system makes it more difficult  
for someone to break into or steal the vehicle.  
If the red indicator light in the driver door lights up  
continuously  
If the red LED light in the driver door flashes for  
about 2 seconds in short intervals, then lights up  
continuously for about 30 seconds, there is a power  
locking system malfunction.  
The anti-theft alarm system is automatically activat-  
ed when the vehicle is locked by pressing the lock  
button on the remote control vehicle key.  
When is the alarm triggered?  
The anti-theft alarm system sounds and the turn  
signals flash for up to 5 minutes if the following oc-  
curs with respect to the locked vehicle:  
— See an authorized Volkswagen dealer or an au-  
thorized Volkswagen Service Facility for assis-  
tance.  
— A door unlocked mechanically with the vehicle  
key bit is opened.

not flash to confirm locking:

— Forcibly opening the engine hood.  
— Forcibly opening the trunk lid.  
— At least one of the doors or the trunk lid is open.  
— Switching on the ignition with an invalid or deac-  
tivated key (a short alarm may sound).

outside using a second valid vehicle key, any key lo-

that was inside the vehicle when it was locked from  
the outside can be reactivated by pressing the

front door handles when a valid vehicle key is in  
range.  
After the alarm has stopped and the vehicle is  
opened again in the same or a different area  
that is protected by the alarm, the alarm is triggered  
again. For example, the alarm will sound again if the  
trunk lid is opened after one of the doors has been  
opened.  
Locking the vehicle after airbag inflation  
If the airbags are activated during a collision, the en-  
tire vehicle is unlocked. Depending on the severity of
