procedure.
The throttle grip must remain in the minimum position, because any other position
inhibits the vehicle starter.
The starter motor will remain active for a maximum of 5 consecutive seconds.
The immobilizer system
In order to enhance theft protection, the vehicle is equipped with a «PIAGGIO IMMO-
BILIZER » electronic engine locking device that is activated automatically when the
ignition switch is removed. Upon start-up, the «PIAGGIO IMMOBILIZER» system
checks the starter key, and only if this key is recognised will the Immobiliser system
allow the vehicle to be started.

Keys (01_11, 01_12, 01_13)
The vehicle is supplied with two types of keys. The red-handgrip key «A» is the
"MASTER" key. Only a single copy of this key is supplied, which is necessary to pro-
gramall your other keysand for your dealerto perform some maintenanceoperations.
We therefore recommend that it be used only under exceptional circumstances. The
blue key «B» (single copy supplied) is used for normal operations and for start-up.
Together with the keys comes a CODE CARD which is imprinted with the mechanical
code of the keys.
WARNING
LOOSING THE RED KEY PREVENTS ANY REPAIRS OF THE 'PIAGGIO IMMO-
BILIZER' SYSTEM AND THE ENGINE CONTROL UNIT.
WARNING

Immobilizer device enabled indicator led (01_14)
Activationofthe «PIAGGIO IMMOBILIZER» system issignalledby a flashing warning
light «U» (see «Analogue instrument panel» section).
In order to reduce battery discharge, the indicator LED turns off automatically after 48
hours of uninterrupted functioning.
Should the system fail, different LED flashing patterns will be provided by an Author-
ised Piaggio Service Centre with information on the type of fault detected.
Operation
Every time the starter key is removed in the "OFF" or "LOCK" position, the safety
system activates the immobilizer system. Turning the key to "ON" disables the engine
lock, provided that the safety system recognises the code transmitted by the key. If
the code is not recognised, turn the key first to "OFF" and then to "ON"; if the lock
cannotbe disabled, try with the other key supplied(red-coloured). If theengine cannot
be started, contact an Authorised Piaggio Service Centre, which is provided with
the electronic equipment required to detect and repair the system. The Immobilizer is
also activated by switching off the engine with the RUN OFF switch. This happens
even if the starter key is in «ON».
When additional keys are required, please note that data storage (up to 3 keys max.)
must be done on all keys, both new ones and existing ones. Take your scooter to an
Authorised Piaggio Service Centre carrying with you the red-handgrip key and all
the blue keys in your possession. The codes of keys not submitted for the new pro-
gramming procedure are deleted from the memory. Any lost keys will therefore not be
enabled to start the engine.
WARNING
EACH KEY HAS ITS OWN AND UNIQUE CODE, WHICH MUST BE STORED IN
THE SYSTEM CONTROL UNIT MEMORY.

After extracting the last blue key, insert the brown key again and turn it to «ON» (carry
out this operation within 10 seconds after extracting the previous key). Leave it in this
