The immobilizer system
In order to enhance theft protection, the vehicle is equipped with a «PIAGGIO IMMOBILIZER » electronic engine locking device that is activated automatically when the
starter key is removed. Upon start-up, the «PIAGGIO IMMOBILIZER» system checks
the starter key, and only if this key is recognised will the immobilizer system allow the
vehicle to be started.

01_11
Keys (01_10, 01_11, 01_12)
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 program all your other keys and for your dealer to perform some maintenance operations.
We therefore recommend that it be used only under exceptional circumstances. The
black 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
LOSING THE RED KEY PREVENTS ANY REPAIRS OF THE "PIAGGIO IMMOBILIZER" SYSTEM AND THE ENGINE CONTROL UNIT.
WARNING
KEEP THE "CODE CARD" AND THE RED HANDGRIP KEY IN A SAFE PLACE
(NOT ON YOUR VEHICLE).
01_12

Immobilizerdevice enabled indicator led (01_13)
Activation of the «PIAGGIO IMMOBILIZER» system is signalled by a flashing warning
light «N» (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-Gilera 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
cannot be disabled, try with the other key supplied (red-coloured). If the engine cannot
be started, contact an Authorised Piaggio Service Centre, which is provided with
the electronic equipment required to detect and repair the system. The immobiliser is
also activated in the engine is switched off with the RUN OFF switch. This happens
even if the starter key is in position "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 the key with the red
grip and all the black keys supplied to an Authorised Piaggio Service Centre. The
codes of keys not submitted for the new storage 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.

1 Vehicle
VIOLENT SHOCKS MAY AFFECT THE ELECTRONIC COMPONENTS OF THE
KEY.
IF OWNERSHIP OF THE VEHICLE IS TRANSFERRED, THE RED HANDGRIP KEY
(AS WELL AS THE OTHER KEYS) AND THE "CODE CARD" MUST ALSO BE
TRANSFERRED TO THE NEW OWNER.
Programming the immobilizer system
Below is described the procedure to follow for programming the PIAGGIO IMMOBILIZER system and/or for storing other key codes. The programming procedure should
be carried out with the engine stop switch set to «RUN».
Procedure start - red key
Insert the red handgrip key in the switch key (in "OFF" position) and turn it to "ON".
After 1 - 3 seconds, turn the key to «OFF » again and pull it out.
Intermediate step - black key
After pulling out the red key, insert the black key within 10 seconds and promptly turn
it to "ON". After 1-3 seconds, turn the key to "OFF" again and pull it out. In this way,
a maximum of 3 black keys can be programmed by repeating the above procedure
keeping the indicated times.
Final step - red key
After pulling out the last black key, insert the red key again and turn it to "ON" (this
operation should be performed within 10 seconds of pulling out the previous key).
Leave it in this position for 1 to 3 seconds and return it to «OFF».
15
01_14
Proper programming check
Insert the red key disabling the transponder (i.e., tilt the key cap by 90°) and turn the
key to "ON". Perform the engine start-up operation. Ensure that the engine does not
start. Insert the black key and repeat the start-up operation. Check that engine starts.
WARNING
SHOULD THE ENGINE START WITH THE RED KEY (WITH TRANSPONDER OFF),
OR IN THE EVENT OF WRONG OPERATION DURING PROGRAMMING, REPEAT
THE PROCEDURE FROM THE BEGINNING.
Accessing the fuel tank (01_14, 01_15, 01_16)
With the key set to «OFF» or «ON», or with engine on, it is possible to electrically open
the saddle by pressing the button «C». If the saddle opening system does not work,
operate the emergency lever «A». Then, unscrew cap «B» and the fuel tank can be
reached.

Identification (01_19, 01_20, 01_21)
The identification registration numbers consist of a prefix followed by a number stamped on both the chassis «A» and the engine «B». These numbers must always be
indicated on spare parts requests. To read the chassis number, lift the saddle and
remove the helmet compartment «C». We recommend checking that the chassis registration number stamped on the vehicle corresponds with that on the vehicle documentation.
CAUTION
BE REMINDED THAT ALTERING IDENTIFICATION REGISTRATION NUMBERS
CAN LEAD TO SERIOUS PENAL SANCTIONS (IMPOUNDING OF THE VEHICLE,
ETC.).

Tyre pressure (02_03)
Check the tyre pressure and wear periodically (roughly every 500 km). The tyres are
equipped with wear indicators; the tyres should be replaced as soon as these indicators become visible on the tyre tread. Also check that tyres do not show cuts on the
sides or irregular tread wear; if this occurs, go to an authorised workshop or at least
a workshop equipped to perform the replacement.
CAUTION
TYRE PRESSURE SHOULD BE CHECKED WHEN TYRES ARE COLD.INCORRECT TYRE PRESSURE CAUSES ABNORMAL TYRE WEAR AND MAKES RIDING DANGEROUS.
TYRES MUST BE REPLACED WHEN THE TREAD REACHES THE WEAR LIMITS
SET FORTH BY LAW.
