Vespa GTS 300 HPE - Owner's Manual > System ASR
ASR SYSTEM
The ASR system is a driving aid that assists the driver in acceleration manoeuvres, particularly on low-grip surfaces or under conditions that can cause sudden back-wheel slippage. The ASR in these situations automatically intervenes by reducing engine output within the limit imposed by the grip conditions, contributing significantly to the maintenance of stability the vehicle.
WARNING
THE ASR SYSTEM IS BASED ON THE RECOGNITION OF SPEED DIFFERENCES BETWEEN FRONT AND REAR WHEEL. IN ORDER FOR THE SYSTEM TO MAINTAIN MAXIMUM EFFICIENCY IN ALL CONDITIONS, THE CALIBRATION PROCEDURE MUST BE PERFORMED EVERY TIME, EVEN IN CASE OF REPLACEMENT OF JUST ONE TIRE.
FOR THE CALIBRATION OF THE CONTROL UNIT PERFORM THE PROCEDURE BELOW.
ASR BUTTON 1: activation / deactivation.
ASR ICON 2: ASR status indicator icon.
ASR ICON FLASHING MODE:
- Frequency of 5 flashes per second (5Hz), with vehicle running: The system is functioning correctly and is active (poor grip conditions, engine power limiting in effect); ride with extreme care, as the grip limit has been exceeded; restore the vehicle safety conditions by gently reducing the throttle opening.
- Frequency of 1 flash per second (2 Hz), with the key in "ON" position and the vehicle at a standstill: The system is active and the calibration is performed. The specific icon will switch off as soon as the ABS system is operational.
- Frequency of 1 flash every 2 seconds (0.5 Hz), with the key in "ON" position and the vehicle at a standstill: the system calibration is in progress.
- Switched on steady can have three meanings:
- calibration procedure performed incorrectly. Perform a new calibration;
- the ASR system is not operating and will not intervene in case of loss of grip;
- the ASR system has been willingly disabled.
- If the deactivation was voluntary (by pressing the appropriate button "1" for 1 second with the engine running) it is recommended to reactivate the system as soon as possible.
- If the system was NOT deactivated voluntarily, this indicates a failure of the ASR system: in this case you must contact an Authorised Service Centre for the diagnosis and the reactivation of the system.
To ensure maximum safety of the vehicle it is advisable to keep the system active.
Deactivation may be necessary only in case of starting with very low grip surfaces (mud, snow) on which the operation of the ASR could actually prevent the movement of the vehicle.
N.B.
WHEN THE KEY IS TURNED TO "ON", THE ABS ICON FLASHES AT THE SAME FREQUENCY AS THE ABS INDICATOR LAMP TO INDICATE THAT THE SYSTEM DIAGNOSIS IS IN PROGRESS. IF NO ERRORS ARE FOUND, THE ASR ICON AND THE ABS INDICATOR LAMP SWITCH OFF AT THE SAME TIME ONCE THE VEHICLE SPEED EXCEEDS 5 Km/h (3 mph).
IF THE ICON AND INDICATOR LAMP DO NOT FLASH WHEN THE ENGINE IS STARTED, THE SYSTEM MAY NOT BE WORKING. CONTACT AN AUTHORISED SERVICE CENTRE.
WARNING
THE ASR SYSTEM IS ACTIVATED AT EVERY "ON" POSITIONING OF THE IGNITION SWITCH.
IF DISABLED BY THE USER, THE ASR SYSTEM KEEPS THE STATE OF INACTIVITY ONLY IF THE VEHICLE IS OFF, BY USING THE ENGINE STOP SWITCH; AT THE NEXT KEY ON THE ASR SYSTEM IS ENABLED AUTOMATICALLY.
CAUTION
IT IS EMPHASISED THAT THE RIDING AUXILIARY SYSTEM CANNOT CHANGE THE PHYSICAL LIMITS OF GRIP AND IS NOT A SUBSTITUTE FOR PROPER MANAGEMENT OF POWER, BOTH ON STRAIGHT STRETCHES AND IN TURNS.
THEREFORE, IT IS RECOMMENDED TO ALWAYS USE THE VEHICLE WITH THE UTMOST CARE AND IN ACCORDANCE WITH THE REGULATIONS IN FORCE.
CAUTION
AT LOW SPEED, LESS THAN 5 Km/h (3 mph), THE ASR SYSTEM IS NOT OPERATIONAL.
IT IS RECOMMENDED TO PAY PARTICULAR ATTENTION IN THE EVENT OF ACCELERATION FROM STANDSTILL IN CONDITIONS OF LOW GRIP, ESPECIALLY IN THE FIRST METRES.
N.B.
IN CASE OF ROAD DISCONNECTIONS THERE COULD BE SHORT ACTIVATIONS OF THE ASR SYSTEM. SUCH EVENT APPEARS UNDER NORMAL OPERATION CONDITIONS OF THE VEHICLE.
N.B.
THE DEVICE PREVENTS IMPRESSING ON THE REAR HIGH SPEED ROTATION WHEEL WITH THE VEHICLE ON THE CENTRE STAND. IT IS RECOMMENDED NOT TO INSIST WITH THE THROTTLE GRIP IN THIS PARTICULAR CONDITION.
CAUTION
A POOR STATE OF MAINTENANCE OF THE TYRES CAN RESULT IN ABNORMAL OPERATION OF THE ASR SYSTEM.
IN CASE OF REPEATED INTERVENTIONS OF THE ASR, EVEN ON ROAD SURFACES WITH GOOD GRIP OR SMALL THROTTLE OPENINGS, IT IS NECESSARY TO CHECK FOR WEAR AND/OR THE STATE OF INFLATION OF TYRES FIRST.
IF THE PROBLEM PERSISTS, CONTACT AN AUTHORISED SERVICE CENTRE.
CAUTION
IN THE EVENT OF MALFUNCTION OF THE BATTERY, THE ABS - ASR SYSTEM TURNS OFF.
ASR SYSTEM CALIBRATION PROCEDURE
In order to maintain the efficiency of the ASR system when one or both tires are replaced, a calibration procedure of the system must be performed as follows on a straight flat stretch of road.
After turning the key to 'ON", the ABS indicator light and the ASR icon "2" flash at the same frequency (fast flashing).
1. Start the vehicle and ride a short distance above 5 km/h (3 mph) and wait for the flashing of the ABS warning light and ASR icon to stop.
2. Stop the vehicle and leave the engine running at idle speed for at least 3 seconds.
3. Turn the ASR system off by pressing the specific button "1" on the handlebar and check that the ASR disabling icon "2" stays on steady.
4. Press at the same time the engine starter button and the ASR on/off button "1" for at least 4 seconds (pulling the LH brake lever has no effect).
5. The activation of the procedure will be confirmed by the ASR icon "2 " switching on with slow flashing (1 flash every 2 seconds).
6. Accelerate to a constant speed of 30 km/h (18.7 mph) and maintain it for at least to 10 seconds.
7. The end of the procedure will be indicated by the switched off ASR icon "2".
8. Once the procedure is complete, it is necessary to turn the ignition switch to "OFF" and wait at least 30 seconds for the next key "ON".
9. In case of failure to complete the procedure within 2 minutes the ASR symbol "2" will stay on steady and the ASR will remain off until the next key "OFF".
10. To restart the ASR, it is necessary to turn the key to "ON" and repeat the procedure until achieving positive result.

The vehicle is equipped with a locking ABS system on the wheels. Tone wheel Speed sensor ABS: It is a hydraulic - electronic device that limits the pressure within the braking circuit when a sensor, located on the wheel, detects its tendency to lock. This system prevents the wheels from locking to avoid the risk of falling.

In order to enhance theft protection, the vehicle is equipped with a "PIAGGIO IMMOBILIZER " electronic engine locking device that is activated automatically when the ignition key 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.
