Oil change indicator "OIL"
This indicator flashes at the initial 1,000 km
(600 mi), then at 5,000 km (3,000 mi) and
every 5,000 km (3,000 mi) thereafter to indi-
cate that the engine oil should be changed.
After changing the engine oil, reset the oil
change indicator. Refer to "To reset the oil
change indicator light".
If the engine oil is changed before the oil
change indicator comes on (i.e. before the
periodic oil change interval has been reached),
the indicator must be reset after the oil change
for the next periodic oil change to be indicated
at the correct time.
The electrical circuit of the indicator can be
checked according to the following procedure.
1. Set the engine stop switch to "
the key to "ON".
2. Check that the indicator comes on for a few
seconds and then goes off.
3. If the indicator does not come on, check the
electrical circuit. Refer to "SIGNALING
SYSTEM" in chapter 8.

engine is revved with the scooter on the cen-
terstand, but this does not indicate a malfunc-
tion.
