low, “LO” will be displayed. When the coolant
temperature rises, the coolant temperature
display will begin to flash. If the coolant tem-
perature continues to rise, the message “HI”
will flash.TIPThe coolant temperature display can be set
to “°C” or “°F”. To switch the temperature
units, turn the key to “ ” (off), then hold
the “RESET” button pushed and turn the
key to “ ” (on).
 The radiator fans turn on and off automati-
cally according to the coolant temperature.
Fuel gauge
The fuel gauge indicates the amount of fuel in
the fuel tank. The display segments of the fuel
gauge disappear from “F” (full) towards “E”
(empty) as the fuel level decreases. When the
last segment on the left flashes, refuel as
soon as possible.1. Fuel gauge

EBU35112CoolantThe coolant level should be checked regular-
ly. In addition, the coolant must be changed
at the intervals specified in the periodic main-
tenance chart.TIPIf genuine Yamaha coolant is not available,
use an ethylene glycol antifreeze containing
corrosion inhibitors for aluminum engines and
mix with distilled water at a 1:1 ratio.
NOTICEECB02190Mix antifreeze with distilled water only.
However, if distilled water is not available,
soft water may be used for refilling. Do not
use hard water or salt water since they are
harmful to the engine. To check the coolant level1. Park the vehicle on a level surface.
2. Wait for the engine to cool for an accurate reading.
3. Look at the coolant level in the coolant reservoir.
Recommended coolant:YAMALUBE coolant
Coolant quantity: Coolant reservoir (up to full level):0.56 L (0.59 US qt, 0.49 Imp.qt)
Radiator (including all routes): 3.78 L (4.00 US qt, 3.33 Imp.qt)

To change the coolant
The coolant must be changed at the intervals
specified in the periodic maintenance chart.
Have a Yamaha dealer change the coolant.
WARNING! Never attempt to remove the
radiator cap when the engine is hot.

Axle bootsCheck the axle boots for holes or tears.
If any damage is found, have them replaced
by a Yamaha dealer.
EBU35121Checking the spark plugsThe spark plug is an important engine com-
ponent which should be periodically
checked, preferably by a Yamaha dealer.
Since heat and deposits will cause any spark
plug to slowly erode, the spark plugs should
be removed and checked in accordance with
the periodic maintenance chart for the emis-
sion control system. In addition, the condition
of the spark plugs can reveal the condition of
the engine.

If a fuse is blown, replace it as follows.1. Turn the key to “ ” (off) and turn off the electrical circuit in question.
NOTICEECB00641To prevent accidental short-circuiting,
turn off the main switch when checking or
replacing a fuse. 2. Remove panel A. (See page 9-10.)
3. Remove the blown fuse, and then install a
new fuse of the specified amperage.
WARNING! Always use a fuse of the specified amperage. Never use any
material in place of the proper fuse.
Using an improper fuse can cause
damage to the electrical system and
may lead to a fire.

4. Turn the key to “ ” (on) and turn on theelectrical circuit in question to check if
the device operates. If the fuse blows
again immediately, have a Yamaha dealer
check the electrical system.
5. Install the panel.EBU35261HeadlightsThis model is equipped with LED headlights.
There are no user replaceable bulbs. If one or
more headlights do not come on, check for a
loose connection, check the headlight fuse,
and then have a Yamaha dealer check the ve-
hicle.TIP When the headlights are set to low beam,
only the top half of each lamp will illuminate.
 When the headlights are set to high beam,
both halves of each lamp will illuminate.

Engine overheating
Wait for the engine to cool before removing the radiator cap. WARNING! If the engine is not
cool when removing the radiator cap, hot fluid and steam could blow out under pressure
and burn you.
[EWB03460]
Place a thick rag over the cap and remove the cap slowly to allow any re-
maining pressure to escape.
TIP Tap water can be used in an emergency. Ch ange to the recommended coolant as soon as
possible.
 The engine will tend to overheat if the radiator is caked with mud, or if air was not properly bled
from the cooling system. Wait until the
engine has cooled.
Check the coolant le vel in the
coolant reservoir and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See TIP.)
Restart the engine. If the engine o verheats again, ask a
Yamaha dealer to inspect and/or repair the cooling system.
