FEATURES
Coolant temperature meter
With the key in the "ON" position, the coolant
temperature meter indicates the temperature
of the coolant. The coolant temperature varies
with changes in the weather and engine load.
If the top segment and coolant temperature
symbol flash, stop the vehicle and let the
engine cool.
CAUTION:
Do not operate the engine if it is over-
heated.
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". 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.
NOTE:
The oil change indicator may flash when the
engine is revved with the scooter on the cen-
terstand, but this does not indicate a malfunc-
tion.
