Automatic Locking When Driving
Whether the automatic locking function is activated on delivery or not is market dependent. The function is deactivated at the factory. The setting can be changed via the menu in the Infotainment control module (ICM).
If this function is activated, the side doors and tailgate lock when the speed exceeds 7 km/h (5 mph). This is on the condition that all side doors and tailgate are closed, the engine is running and the vehicle is moving forward. Information about whether the engine is running or not is discovered by the Central electronic module (CEM) via a calculation of different signals that are transmitted from other control modules to the Central electronic module (CEM), e. g. key position.
Indication about whether the engine drives the vehicle forward differs between vehicles with a manual or automatic transmission.
On vehicles with an automatic transmission, the gear selector position is obtained from the Transmission control module (TCM). The gear selector must not be in P or N in order for automatic locking to work.
On vehicles with a manual transmission, the Central electronic module (CEM) receives information about the vehicles speed from the Brake control module (BCM). At the same time the accelerator pedal must be partially affected in order for locking to be carried out.
The door can be unlocked again as normal using the central locking switches.
