Lock in Driver's Door & Front Passenger's Door
The capacitive sensor 1 initiates the vehicle unlocking procedure.
The lock in the driver's door and front passenger's door is equipped with an additional
spring to ensure the vehicle can be opened fast enough. The spring exerts pretension on
the central locking drive unit for the unlocking procedure. The door is already unlocked
before an attempt is made to open it with the outer door handle.
Note: If pulled very fast, however, it may be necessary to pull the outer door
handle a second time in order to open the door.
