Introduction of the smart fortwo, Model Series 451
Central locking (CL [ZV])
The central locking in the smart fortwo includes the
locking and unlocking of both doors and the fuel filler
flap, and the opening of the rear-end door in the
smart coupé or the opening of the soft top on the
smart cabrio. A distinction is drawn between manual
and automatic functions.
Manual functions:
• Remote control with the transmitter key
• Door opening from the inside
• Operation via the interior CL [ZV] locking and
unlocking switches in the cockpit switch group
• Manual unlocking with the transmitter key at the
driver-side door lock
Automatic functions:
• Speed-dependent locking
• Emergency opening after crash detection
• Relocking
Unlocking or locking via the transmitter key
When the Unlock or Lock button on the transmitter key
is pressed, it sends a radio signal to the SAM control
unit. The SAM control unit checks the access authori-
zation of the transmitter key. If the access authoriza-
tion is valid, it actuates the following motors directly
to unlock or lock the vehicle:
• Right door CL [ZV] motor
• Left door CL [ZV] motor
• Fuel filler flap CL [ZV] motor
When the vehicle is globally unlocked, the rear-end
door handle switch is enabled; and when the vehicle is
locked, it is disabled.
If the rear-end door handle switch is actuated when
the central locking has been globally unlocked, the
SAM control unit directly actuates the trunk lid CL
[ZV] motor to unlock the rotary tumbler.
Selective unlocking
If the Unlock button on the transmitter key is pressed
once, only the driver door and fuel filler flap are
unlocked. The anti-theft alarm system is deactivated
and all turn signal indicators flash once.
Global unlocking
If the Unlock button on the transmitter key is pressed
again, the passenger door is unlocked and the rear-
end door handle switch is enabled. The turn signal
indicators flash again once.
Door opening from the inside
The vehicle doors can always be opened from the
inside with the door handle regardless of the status of
the central locking. In this case, only the respective
vehicle door and the fuel filler flap are unlocked.
