Oil level warnin g li ght “ ”
This warning light comes on when the
engine oil level is low. To prevent en-
gine damage, replenish the engine oil
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 occurs, have a Yamaha dealer
check the vehicle.
TIPWhen the vehicle is turned on, this light
will come on for a few seconds and
then go off. If the light does not come
on, or if the light remains on after con-
firming that the oil level is correct (see
page 6-11), have a Yamaha dealer
check the vehicle.

QS in
dicator
This indicator comes on when the
quick shift system (page 3-19) is turned
on. Multi-function
display
The multi-function display can show
the following:  odometer (ODO)
 two tripmeters (TRIP 1 and TRIP 2)
 fuel reserve tripmeter (TRIP F)
 instantaneous fuel consumption
 average fuel consumption
 coolant temperature
 air temperature
TIPThe odometer will lock at 999999.
 The tripmeters reset and continue
counting after 9999.9 is reached.
Push the “SELECT” switch to change
the display between the odometer
“ODO”, the tripmeters “TRIP 1” and
“TRIP 2”, instantaneous fuel consump-
tion “km/L”, “L/100 km”, or “MPG”, av-
erage fuel consumption “AVE – –.–
km/L”, “AVE – –.– L/100 km”, or “AVE
– –.– MPG”, coolant temperature “°C”,
and air temperature “°C Air”. When
pushing “ ”, the display will change
in the following order.
ODO → TRIP 1 → TRIP 2 → km/L,
L/100 km, or MPG → AVE – –.– km/L,
AVE – –.– L/100 km, or AVE – –.– MPG
→ °C (coolant) → °C Air → ODO

3 When the last segment of the fuel me-
ter starts flashing, the display changes
to the fuel reserve tripmeter “TRIP F”
and starts counting the distance trav-
eled from that point. In this case,
push “ ” to change the display in the
following order.
TRIP F
→ km/L, L/100 km, or MPG →
AVE – –.– km/L, AVE – –.– L/100 km, or
AVE – –.– MPG → °C (coolant) → °C Air
→ ODO → TRIP 1 → TRIP 2 → TRIP F
TIP Push “ ” to change the display
in the opposite order.
 To reset a tripmeter, push the
“RESET” button for one second.
 The fuel reserve tripmeter can be
reset manually, or you can allow it
to reset automatically after refuel-
ing and traveling about 5 km (3
mi).
Instantaneous fuel consumption
Instantaneous fuel consumption can
be set to “km/L”, “L/100 km”, or
“MPG”.
 “km/L”: the distance that can be
traveled on 1.0 L of fuel
 “L/100 km”: the amount of fuel
necessary to travel 100 km
 “MPG”: the distance that can be
traveled on 1.0 Imp.gal of fuelTIPTo switch between “km/L”, “L/100
km”, and “MPG”, push the “RE-
SET” button for one second.
 When traveling under 10 km/h (6
mi/h), “– –.–” is displayed.
Averag e fuel consumption
Average fuel consumption can be set
to either “AVE – –.– km/L”, “AVE – –.–
L/100 km”, or “AVE – –.– MPG”.  “AVE – –.– km/L”: the average dis-
tance that can be traveled on 1.0 L
of fuel
 “AVE – –.– L/100 km”: the average
amount of fuel necessary to travel
100 km
 “AVE – –.– MPG”: the average dis-
tance that can be traveled on
1.0 Imp.gal of fuelTIPTo reset the average fuel con-
sumption, push the “RESET” but-
ton for one second.

After resetting, “– –.–” will be
shown until the vehicle has trav-
eled a sufficient distance.
 The display units cannot be
switched between “km/L”, “L/100
km”, and “MPG” in this mode;
change to the instantaneous fuel
consumption mode first.
Coolant temperature
The temperature of the engine coolant
from 40 °C to 124 °C is shown in 1 °C
increments.
If the message “Hi” flashes, stop the
vehicle, then stop the engine and let it
cool. (See page 6-36.)
TIPWhen the coolant temperature is
below 40 °C, “Lo” will be dis-
played.
 The coolant temperature varies
with changes in the weather and
engine load.Air temperature
The temperature of the air drawn into
the intake system from –9 °C to 50 °C
is shown in 1 °C increments.TIP–9 °C will be displayed even if the
air temperature falls below –9 °C. 
The temperature displayed may
vary from the actual ambient tem-
perature.
Brig htness and shift light control

This mode cycles through five control
functions in the order listed below.  Display brightness
 Shift light on / flash / off
 Shift light on r/min
 Shift light off r/min
