3 Series E91 330xi (N52) TOUR
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 (US version)
When the hotel position is selected, the boot lid also stays locked after the vehicle is unlocked. For hotel position
to be selected, the setting of the hotel position switch is detected.
Crash unlocking
A crash is recognised as such by the MRS control unit (E87, E90, E91, E92) or ACSM control unit (E93). A
crash signal is transmitted by 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.
After a crash, the central locking system cannot be operated until terminal R has been switched off for at least 3
seconds.
(MRS = "Multiple Restraint System"; ACSM = "Advanced Crash Safety Module", alternatively known as the
"Crash Safety Module")
Forced unlocking
When the CAS detects that a remote control is locked in place in the slot, the central locking system is released.
The central locking system adopts the "Locking" position.
The anti-theft alarm is also deactivated during forced release.
Lockout protection
To protect the driver against unintentionally locking himself out, all operating points are locked when the driver's
door is open. This makes any additional mechanical lockout protection in the door locks unnecessary.
Repeat interlock
To protect the central locking drives (doors, tailgate, fuel filler flap, rear window, glove compartment and stowage
compartment in the centre console) against overloading, the CAS monitors repeat operation.
If there are more than 15 attempts at activation within one minute, the drives are not unlocked for a certain time.
Automatic relocking
If the central locking system is unlocked using the remote control and no door or boot lid is opened within 2
minutes, the vehicle is automatically locked again (locked and secured).
This function can be activated via the personal profile.
Voltage monitoring
The function range for the central locking system is specified as being from 9 to 16 volts. Outside this range,
the drives will not be actuated.
If the power supply is interrupted, the status of the central locking system will not change (anti-theft protection).
Selective unlocking
The first time there is an unlocking command, only the driver's door is unlocked. The central locking system sets
all other doors from deadlock to lock. The anti-theft alarm system is switched off and the doors remain locked.
The second time there is an unlocking command, the remaining doors are unlocked.
This function can be activated via the personal profile (depends on national version concerned).
