Mechanical asynchronicity
Locking
A locked door cannot be opened from the outside. However, the door can still be opened from the inside. To do
this, the door handle must be pulled twice.
Locking is performed in the following ways:
•
Operation of the central locking button (condition: front doors must be closed)
•
Operation via the driver's door lock cylinder or the remote control, where the conditions for deadlocking are
not fulfilled (see "Deadlocking").
Deadlocking
A deadlocked door cannot be opened from the inside or outside.
A door is deadlocked if the vehicle is locked via the driver's door lock cylinder or the remote control.
Conditions:
•
Terminal R OFF
•
Driver's door or front-passenger door was opened
•
Driver's door closed
When the vehicle is deadlocked, the anti-theft alarm DWA is also primed.
Unlocking
An unlocked door can be opened from the inside and the outside.
When the vehicle is unlocked, the anti-theft alarm DWA is also deactivated.
Hotel position
The hotel position is applied via the lock cylinder in the boot lid (E60).
On the E63/E64 the hotel position switch is in the rear stowage compartment of the centre console.
When the hotel position is applied, the boot lid also stays locked after the vehicle is unlocked.
On the E63/E64 the front stowage compartment of the centre console also stays locked.
The boot lid pushbutton in the interior footwell and the outside boot lid pushbutton are deactivated. Application of
the hotel position is detected from the position of the boot lid lock cylinder or by the hotel position switch.
Crash unlocking
A crash is detected by the passive safety system ASE (= Advanced Safety Electronics). The crash signal is
reported by the safety and gateway module (SGM) to the CAS control unit. The message is sent on the K-CAN.
The CAS control unit unlocks the vehicle.
All operating points are disabled when there is a crash signal. This prevents unintentional actions of the central
locking system from occurring due to short circuits caused by the accident.
The central locking system can only be reactivated after a crash once terminal R has been switched off for at
least 3 seconds.
Forced unlocking
If the CAS detects that a key is engaged in the ignition starter switch, the central locking system is released. The
central locking system assumes the "Lock" position.
The anti-theft alarm system is also deactivated during forced release.
