CAUTION:
Do not mix more than one type of ethyl-
ene glycol antifreeze containing corro-
sion inhibitors for aluminum engine.
Do not use water containing impurities or
oil.
Recommended coolant:

Coolant capacity:
1.0 L (0.88 Imp qt, 1.06 US qt)
Handling notes of coolant:
The coolant is harmful so it should be han-
dled with special care.
WARNING
When coolant splashes to your eye.
Thoroughly wash your eye with water
and see your doctor.
When coolant splashes to your clothes.
Quickly wash it away with water and
then with soap.
When coolant is swallowed.
Quickly make him vomit and take him
to a doctor.
9. Install:
Radiator cap
Start the engine and warm it up for a
several minutes.
10. Check:
Coolant level
Coolant level low → Add coolant.

CHECKING THE TAILLIGHT (LEDs)
1. Disconnect the taillight coupler.
2. Connect two jumper leads 1 from the bat-
tery terminals to the respective coupler ter-
minal as shown.
3. Check:
•LED (for proper operation)
Does not light → Replace the taillight
assembly.
WARNING
A wire that is used as a jumper lead must
have at least the same capacity of the bat-
tery lead, otherwise the jumper lead may
burn.
This check is likely to produce sparks,
therefore, make sure no flammable gas or
fluid is in the vicinity.
