PIAGGIO MP3 LT 500 i.e. Series Manual page 31

•
SWITCH «1»: on / off.
•
WARNING LIGHT «2»: operating indication warning light.
Flashing mode:
- Off with the vehicle in gear: the system is working, but is not active (normal condition).
- Flashing quickly with moving vehicle: the system is up and running (conditions of low
grip and intervention to reduce engine power); we recommend the utmost caution
because the grip limit has been exceeded; restore the vehicle safety conditions by
gently reducing the throttle opening.
01_38
- Lit with moving vehicle: the system is disabled and will not intervene in case of loss
of grip.
•
If the deactivation was voluntary (by pressing the appropriate button «1» for
1 second) it is recommended to replace the system as soon as possible.
•
If the deactivation was NOT voluntary, there is an ASR failure: 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.
AT VEHICLE START-UP THE ASR WARNING LIGHT FLASHES AT THE SAME
FREQUENCY AS THE ABS WARNING LIGHT, INDICATING A DIAGNOSTIC
PHASE OF THE SYSTEM. IN THE ABSENCE OF ERRORS, BOTH WARNING
LIGHTS TURN OFF AT THE SAME TIME WHEN EXCEEDING 5 KM/H.
IN CASE OF ABSENCE OF FLASHING AT START-UP, THE SYSTEM MAY NOT
WORKING, PLEASE CONTACT AN AUTHORISED SERVICE CENTRE.
