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.
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.
01_10
WARNING
LOSING THE RED KEY PREVENTS ANY REPAIRS OF THE "PIAGGIO IMMOBILIZER" SYSTEM AND THE ENGINE CONTROL UNIT.
WARNING
01_11
KEEP THE "CODE CARD" AND THE RED HANDGRIP KEY IN A SAFE PLACE
(NOT ON YOUR VEHICLE).

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 Authorised Piaggio-Gilera Service Centre with information on the type of fault detected.
01_13
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.
1 Vehicle
WARNING
EACH KEY HAS ITS OWN AND UNIQUE CODE, WHICH MUST BE STORED IN
THE SYSTEM CONTROL UNIT MEMORY.
14
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».

time lean the vehicle on you.
02_10
Automatic transmission (02_11, 02_12)
To ensure simple, pleasurable riding, the vehicle is equipped with automatic transmission with regulator and centrifugal clutch. The system is designed to provide the
best performance (acceleration and consumption) while riding on both flat roads and
uphill.
If you have to stop on an uphill slope (traffic lights, traffic jam, etc.) use only the brake
to keep the vehicle still, leaving the engine running at idle speed. Using the
engine to keep the vehicle still can cause the clutch to overheat, due to the
friction of the clutch mechanism itself against the clutch bell.
02_11
It is therefore recommended to avoid conditions of prolonged clutch slippage (other
than those previously indicated) like driving uphill fully laden on steep slopes or starting
off with driver and passenger at slopes greater than 25%.
Observe the following precautions if the clutch overheats:
29
1.Do not continue riding in such conditions.
2. Let the clutch cool down with the engine at idle speed for a few minutes.
02_12
Safe driving (02_13, 02_14)
Some simple tips are provided below that will enable you to use your scooter on a
daily basis in greater safety and peace of mind. Your skill and your mechanical knowledge are the basis of a safe ride. We recommend trying out the vehicle in traffic - free
zones, in order to acquire a good knowledge of the vehicle it self.
1. Before riding off, remember to put on your helmet and fasten it correctly.
2.Reduce speed on rough roads and drive with care.
02_13
3. After driving on a long stretch of wet road without using the brakes, the braking
effect is initially lower. In these conditions, it is a good idea to apply the brakes from
time to time.
4. Do not brake hard on wet, unsurfaced or slippery road surfaces.
5. Avoid riding off by mounting the scooter when resting on the support. In any case,
the rear wheel should not be turning when in comes into contact with the ground, in
order to avoid abrupt departures.
2 Use
6. If driving over roads affected by sand, mud, snow mixed with salt, etc. We advise
you to frequently clean the brake disc with a mild detergent to prevent the accumulation of abrasive elements inside the eyelets leading to premature wear on the brake
pads.

03_01
Engine oil level (03_01)
3 Maintenance
In 4T engines, engine oil is used to lubricate the distribution elements, main bearings
and thermal group. An insufficient quantity of oil can seriously damage the engine. In all four-stroke engines, a loss of efficiency in oil performance and certain
consumption should be considered normal. Consumption can particularly reflect the
conditions of use (i.e. when driving at 'full acceleration' all the time, oil consumption
increases). The replacement intervals provided for by the maintenance programme
are defined depending on the total content of oil in the engine and the average consumption measured following standardised methods. In order to prevent any problems, we recommend checking oil level more frequently than indicated in the
Scheduled Maintenance table or before setting off on long journeys. The vehicle
is, however, equipped with an oil pressure warning light on the instrument panel.
34
Every time the scooter is used, a visual check should be made on the level of the
engine oil when the engine is cold. The oil level should be somewhere between the
MAX and MIN index marks on the level bar; the check must be made with the scooter
upright, resting on the centre stand. If the check is carried out after the vehicle has
been used, and therefore with a hot engine, the level line will be lower; in order to carry
out a correct check, wait at least 10 minutes after the engine has been stopped so as
to get the correct level.
03_02
Engine oil top-up
Any topping up with oil must be carried out after checking the oil level by adding oil,
but never exceeding the MAX level. Getting an oil level between the MIN and
MAX marks requires approx. 400 cm³ of oil. Every 3000 km, however, take your
scooter to an Authorised Piaggio Service Centre to have the engine oil level should
be checked and if necessary, topped up.
Warning light (insufficient oil pressure)
The vehicle is equipped with a warning light that comes on when the key is turned to
«ON». However, this light should come off once the engine has been started. If the
light comes on while braking, at idle speed or while turning a corner, it is necessary to check the oil level and top it up if required. If after having topped-up
the oil, the warning light still comes on while braking, at idle speed or while
turning a corner, it will be necessary to take your vehicle to an Authorised Service Centre.
35
3 Maintenance
Engine oil level check (03_02)
Engine oil change (03_03)
The oil and the cartridge filter «C» must be changed after 1000 km and every 6000
km at an Authorised Piaggio Service Centre. The engine should be emptied by
draining the oil from the drainage plug «B» of the gauze filter on the flywheel side. In
order to facilitate the oil drainage, loosen the cap/dipstick. Since a certain quantity of
oil still remains in the circuit, filling must be done with approx 600 ÷ 650 cm³ of oil
through the cap «A». Then start up the scooter, leave it running for a few minutes and
switch it off: after five minutes, check the level and if necessary top-up without exceeding the MAX. level. The cartridge filter must be replaced at every oil change.
For top-ups and changes, use new oil of the recommended type.
03_03
WARNING
RUNNING THE ENGINE WITH INSUFFICIENT LUBRICATION OR WITH INADEQUATE LUBRICANTS ACCELERATES THE WEAR AND TEAR OF THE MOVING
PARTS AND CAN CAUSE IRRETRIEVABLE DAMAGE.
WARNING
EXCESSIVE OIL LEVEL AT TOP-UPS CAN LEAD TO SCALE FORMATION AND
VEHICLE MALFUNCTION.

In order to reduce polluting emissions, the vehicle is furnished with a catalytic converter in the muffler.
3 Maintenance
To facilitate the catalytic process, a further quantity of previously filtered air is brought
in through the exhaust duct on the head by the secondary air system (SAS).
This system allows more oxygen to be added to the unburned gases before reaching
the catalytic converter, thus improving the catalytic converter reaction.
03_14
The system has a control valve that disables operation during deceleration in order to
avoid abnormal noises.

This system requires a filter «A».
The filter sponge should be cleaned with water and mild soap, then it should be dried
with a cloth and slight blows of compressed air.
Cooling fluid level (03_15, 03_16)
03_15
Engine cooling is carried out by a forced-circulation coolant system. The cooling circuit
holds approx. 2.100 ÷ 2.150 l of coolant consisting of a mixture of 50% de-ionised
water and 50% glycol ethylene-based antifreeze solution with corrosion inhibitors. The
recommended coolant, supplied with the scooter, is already mixed and ready for use.
For proper functioning of the engine, ensure that the pointer of the coolant temperature
gauge remains in the middle area of the scale. If the pointer of the gauge enters the
red zone, shut off the engine, allow it to cool down and check the coolant level; if level
is OK, take your scooter to an Authorised Piaggio Service Centre. Should the coolant level exceed the above values during a non-demanding ride, shut off the engine
and let it cool down. Then check the coolant level. if level is OK, take your scooter to
an Authorised Piaggio Service Centre. Check coolant when the engine is cold at
the intervals indicated in the scheduled maintenance table, following the steps below.
a) Place the scooter in a vertical position on the stand.
b) Unscrew the fixing screw «A» and remove the cover.
c) Check the fluid level according to the two marks- MIN and MAX «B» on the reservoir
d) Top-up, if required, if the fluid level is below the MIN level on the scale inside the
expansion tank. The fluid level must always be between MIN and MAX level
03_16
If the fluid is near the minimum level, top-up only when the engine is cold. If it is necessary to top up the coolant frequently, or if the expansion tank is completely dry, you
should look for the cause in the cooling system. It is therefore indispensable to have
the cooling system checked at an Authorised Piaggio Service Centre. Change

CAUTION
Long periods of inactivity
Battery performance will decrease if the vehicle is not used for a long time. This is the
result of the natural phenomenon of battery discharging plus residual absorption by
vehicle components with constant power consumption. Poor battery performance may
also be due to environmental conditions and the cleanliness of the poles. In order to
avoid difficult starts and/or irreversible damage to the battery, follow any of these
steps:
- At least once a month start the engine and run it slightly above idle speed for 10-15
minutes. This keeps all the engine components, as well as the battery, in good working
order.
- Take your vehicle to a garage (as indicated in the «Vehicle not used for extended
periods» section) to have the battery removed. Have the battery cleaned, charged
fully and stored in a dry, ventilated place. Recharge at least once every two
months.
N.B.
THE BATTERY MUST BE CHARGED WITH A CURRENT EQUAL TO 1/10 OF THE
RATED CAPACITY OF THE BATTERY AND FOR NOT LONGER THAN 10 HOURS.
CONTACT AN AUTHORISED SERVICE CENTRE TO CARRY OUT THIS OPERATION SAFELY. WHEN REFITTING THE BATTERY MAKE SURE THE LEADS ARE
CORRECTLY CONNECTED TO THE TERMINALS.
