Coolant temperature gauge
With the key in the “ON” position, the
coolant temperature gauge indicates
the temperature of the coolant. When
the key is turned to “ON”, the coolant
temperature gauge needle will sweep
once across the temperature range and
then return to “C” in order to test the
electrical circuit. The coolant tempera-
ture varies with changes in the weather
and engine load. If the needle reaches
or enters the red zone, stop the vehicle
and let the engine cool. (See
page 6-36.)
NOTICE

Do not continue to operate the en-
gine if it is overheating.

Checking the wheel bearings
The front and rear wheel bearings must
be checked at the intervals specified in
the periodic maintenance and lubrica-
tion chart. If there is play in the wheel
hub or if the wheel does not turn
smoothly, have a Yamaha dealer check
the wheel bearings.

Battery
This model is equipped with a VRLA
(Valve Regulated Lead Acid) battery.
There is no need to check the electro-
lyte or to add distilled water. However,
the battery lead connections need to be
checked and, if necessary, tightened.
NOTICE
ECA10620
Never attempt to remove the battery
cell seals, as this would permanent-
ly damage the battery.
WARNING
EWA10760
Electrolyte is poisonous and
dangerous since it contains sul-
furic acid, which causes severe
burns. Avoid any contact with
skin, eyes or clothing and al-
ways shield your eyes when
working near batteries. In case
of contact, administer the fol-
lowing FIRST AID.
EXTERNAL: Flush with plenty
of water.
INTERNAL: Drink large quan-
tities of water or milk and im-
mediately call a physician.
EYES: Flush with water for 15
minutes and seek prompt
medical attention.
Batteries produce explosive hy-
drogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and pro-
vide sufficient ventilation when
charging it in an enclosed
space.
KEEP THIS AND ALL BATTER-
IES OUT OF THE REACH OF
CHILDREN.

9To charge the battery
Have a Yamaha dealer charge the bat-
tery as soon as possible if it seems to
have discharged. Keep in mind that the
battery tends to discharge more quickly
if the vehicle is equipped with optional
electrical accessories.
NOTICE
ECA16520
To charge a VRLA (Valve Regulated
Lead Acid) battery, a special (con-
stant-voltage) battery charger is re-
quired. Using a conventional battery
charger will damage the battery. If
you do not have access to a con-
stant-voltage battery charger, have a
Yamaha dealer charge your battery.
To store the battery
1. If the vehicle will not be used for
more than one month, remove the
battery, fully charge it, and then
place it in a cool, dry place.
NOTICE:
When removing the
battery, be sure the key is turned
to “OFF”, then disconnect the
negative lead before discon-
necting the positive lead.
[ECA16302]
2. If the battery will be stored for more
than two months, check it at least
once a month and fully charge it if
necessary.
3. Fully charge the battery before in-
stallation.
4. After installation, make sure that
the battery leads are properly con-
nected to the battery terminals.
NOTICE
ECA16530
Always keep the battery charged.
Storing a discharged battery can
cause permanent battery damage.
