CENTRAL LOCKING
The vehicle can be locked in three ways, Central Door locking switch (CDL), ve-
hicle key or remote Plip key. The CDL switch is located inside the vehicle, nor-
mally in the centre console. This allows the locks to be operated without arming
the alarm system. If the inertia switch is operated, then the CDL is overridden
and the locks are opened automatically.
The vehicle can be CDL locked by using the key in the drivers door. Turning the
key anti-clockwise will lock all the doors, turning the key a second time will su-
per lock the doors (Note second turn must be within 1 second of the first turn).
If the vehicle has an alarm and is CDL locked or super locked, turning the key
clockwise will only mechanically unlock the drivers door. The system then enters
EKA access mode.
If the vehicle has no alarm system, then turning the key clockwise once will
open all doors. If the vehicle is super locked then the drivers door will open, and
a second turn of the key will open the other remaining doors. If the remote con-
trol unit is used to unlock the vehicle, pressing the unlock button once will
unlock the drivers door only, pressing the button for the second time all other
doors will unlock.
