CENTRAL LOCKING
SYSTEM FEATURES:
• The Central Locking system controls the door locks, tailgate locks and Fuel Filler Flap
actuators.
• The familiar single/double locking strategy is maintained from previous systems with a
new style door lock mechanismcombined with dual actuator motors similar to that
of the E46 ZKE V system.
• The automatic locking feature activates the door lock actuators when a road speed
signal of 7.5 MPH is detected via the K-Bus. The factory default encoding of this
feature is off, but can be encoded on for individual users with the Key Memory function.
• The Driver’s door lock location is the only point outside of the vehicle where the key can
mechanically control the central locking system functions. The lock incorporates the
familiar overrunning lock cylinder that breaks away and freewheels if an attempt is made
to destroy the lock with a screwdriver, dent puller, etc.
• The selective unlocking feature is maintained. A single unlock request from the driver’s
door with the key or via the remote transmitter unlocks the driver’s door only. A second
unlock request unlocks the remaining doors and trunk. This feature can be modified
for individual users with the new Key Memory capabilities to activate all lock actuators
simultaneously.
• When unlocked, the X5 uppertailgate can be opened by:
- the tailgate button in the center console SZM,
- trunk release switch pad located above the license plate, or
- the trunk release button on an FZV key.
• With the upper tailgate open, the lower tailgate is then opened by depressing the switch
located along it’s top edge.
• GM and EWS 3.3 interface via the K bus to monitor double lock status and to initiate
double lock override. This feature allows the doors to be opened from the inside if an
accepted EWS key is switched on in the ignition when double locked.
