CoolantThe coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.TIPIf genuine Yamaha coolant is not avail-
able, use an ethylene glycol antifreeze
containing corrosion inhibitors for alu-
minum engines and mix with distilled
water at a 1:1 ratio.
EAU78580
To check the coolant level
1. Place the vehicle on the center- stand.
TIPThe coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.2. Check the coolant level through
the check window.TIPThe coolant should be between the
minimum and maximum level marks.
3. If the coolant is at or below theminimum level mark, remove the
left floorboard mat by pulling it up.
4. Remove the coolant reservoir cov- er.
Recommen ded coolant:
YAMALUBE coolant
Coolant quantity: Coolant reservoir (max level mark):0.18 L (0.19 US qt, 0.16 Imp.qt)
Radiator (including all routes): 1.10 L (1.16 US qt, 0.97 Imp.qt)

Replacin g the fusesThe main fuse and the fuse boxes,
which contain the fuses for the individ-
ual circuits, are located under panel A.
(See page 7-8.)TIPTo access the main fuse, remove the
starter relay cover as shown.
If a fuse is blown, replace it as follows.
1. Turn the main switch off and turn off the electrical circuit in ques-
tion.
2. Remove the blown fuse, and then install a new fuse of the specified
amperage. WARNING! Do not

Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See TIP.)
