5) ABS light (orange) (ST4s ABS)
Turns on for a few seconds when the key is turned to
ON (CHECK) and then goes out; ABS on.
Turns on and flashes when the ABS system has been
turned off using the button incorporated in the LH
switch (see page 31).
Important
When the ABS light stays on, it means the ABS is not
working. This will not affect the operation of the regular
braking system. However, contact a Dealer or Authorised
Workshop. A possible cause is insufficient battery voltage
and it is a good rule to charge the battery. Another possible
cause is a fault in the system.
