as soon as possible.
Even if the oil level is sufficient, the
warning light may flicker when riding
on a slope or during sudden accelera-
tion or deceleration, but this is not a
malfunction. If a problem is detected in
the oil level detection circuit, the oil lev-
el warning light will flash repeatedly. If

This warning light comes on when you
are low on fuel. When the fuel level
drops below approximately 3.4 L (0.90
US gal, 0.75 Imp.gal), the light will
come on to remind you to refuel as
soon as possible.
When the vehicle is turned on, the light
will perform a circuit check (come on
for a few seconds and then go off).
If the warning light does not come on

ing light remains on after refueling,
have a Yamaha dealer check the vehi-
cle.TIPIf a malfunction is detected, the fuel
level warning light will flash repeatedly.
Have a Yamaha dealer check the vehi-
cle.

the load on the engine immediately. If
message “HI” flashes in the coolant
temperature display, stop the vehicle,
then stop the engine and let the engine
cool.
The electrical circuit of the warning
light can be checked by turning the ve-
hicle on. The warning light should
come on for a few seconds, and then

This display indicates the temperature
of the coolant from 41 °C to 124 °C in
1 °C increments.
If the coolant temperature is between
117 and 124 °C, the coolant tempera-
ture display flashes and the coolant
temperature warning light comes on. If
this occurs, reduce the load on the en-
gine by riding at a moderate pace, at
low rpm, until the coolant temperature
goes down. If the temperature does
not go down, or if the message “HI”
flashes, stop the engine and let it cool.
(See page 7-42.)
TIP
When the vehicle is turned on, the
coolant temperature display is au-
tomatically selected.
 When the coolant temperature is
below 41 °C, “Lo” will be dis-
played.Air temperature display
This display indicates the temperature
of the air drawn into the air intake duct.
Push the “RESET” button to switch the
display between the coolant tempera-
ture and the air temperature.
TIPWhen the coolant temperature
display is selected, “C” is dis-
played for one second, and then
the coolant temperature is dis-
played.
 When the air temperature display
is selected, “A” is displayed for
one second, and then the air tem-
perature is displayed.
 When the air temperature is below
–9 °C, “–9 °C” will be displayed.
 The temperature displayed may
vary from the actual ambient tem-
perature.Transmission gear display

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.
EAU3908B
To check the coolant level
Since the coolant level varies with en-
gine temperature, check when the en-
gine is cold.
1. Park the vehicle on a level surface. 2. With the vehicle in an upright posi-
tion, look at the coolant level in the
reservoir.
3. If the coolant is at or below the minimum level mark, remove pan-
el B to access the coolant reser-
voir. (See page 7-9.)
4. Remove the coolant reservoir cap. WARNING! Remove only the
coolant reservoir cap. Never at-
tempt to remove the ra diator
cap when the en gine is hot.
[EWA15162]
5. Add coolant to the maximum level
mark. NOTICE: If coolant is not
availa ble, use d istilled water or
soft tap water instea d. Do not
use har d water or salt water
since it is harmful to the en gine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possi ble, other-
wise the coolin g system will not
b e protecte d a gainst frost an d
corrosion. If water has been
a dde d to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possi ble, otherwise the
effectiveness of the coolant will
b e re duce d.
