CIRCUIT OPERATION
Basic Overview – Central Door Locking
All new Range Rover models feature Central Door
Locking.
All four doors and the tailgate can be locked and
unlocked through operation of the central locking
system, which can be operated by:
D
Pressing down, or lifting up, either of the front
door sill buttons.
D
Turning the key clockwise (to lock), or turning the
key anti–clockwise (to unlock), with the key in
the drivers door lock.
D
Pressing the “lock” button, or pressing the
“unlock” button, on the remote handset.
The new Range Rover is also equipped with a
“Superlocking” feature. When the vehicle is
“Superlocked”, it is impossible to unlock any of the
doors from inside the vehicle by lifting any of the sill
buttons.
Basic Overview – Alarm
All new Range Rovers are equipped with a
sophisticated integrated security system.
The alarm system offers the following forms of
protection:
D
Perimetric protection against unauthorised open-
ing of any of the hinged “slam” panels.
D
Engine crank inhibit against unauthorised engine
crank.
D
Electronic engine immobilisation against unau-
thorised engine start.
D
Volumetric protection against intrusion into the
passenger compartment.
Basic Overview – Lazy Locking
An additional feature of the new Range Rover’s
security system is Lazy Locking.
Lazy Locking enables the driver to close any open
glass panel (window or sunroof) from outside the car
using either the key or the remote handset.
Lazy Locking can be carried out either when locking
or super locking the vehicle, or when the vehicle is
already in a locked state.
N.B. Activation of a lazy locking sequence will be
dependent on market requirements.

the following components:
D

ing central door locking, superlocking and
