NOTICE
ECA10022
Do not continue to operate the en-
gine if it is overheating.TIPThe coolant temperature varies with
changes in the weather and engine
load.Transmission gear displayThis display shows the selected gear.
The neutral position is indicated by “ ”
and by the neutral indicator light.
Multi-function display
The multi-function display is equipped
with the following:
an odometer
two tripmeters
a fuel reserve tripmeter
an instantaneous fuel consump-
tion display
an average fuel consumption dis-
play
an oil change tripmeter
an oil change indicator
The odometer shows the total distance
traveled by the vehicle.The tripmeters show the distance trav-
eled since they were last set to zero.
Push the “SEL” button to switch the
display between the odometer mode
“ODO”, tripmeter modes “TRIP 1” and
“TRIP 2”, instantaneous fuel consump-
tion mode “km/L” or “L/100 km”, aver-
age fuel consumption mode “AVE_ _._
km/L” or “AVE_ _._ L/100 km” and oil
change tripmeter mode “OIL TRIP” in
the following order:
ODO → TRIP 1 → TRIP 2 → km/L or
L/100 km → AVE_ _._ km/L or AVE_ _._
L/100 km → OIL TRIP → ODO
The fuel reserve tripmeter shows the
distance traveled since the fuel level
warning light came on.
If the left segment of the fuel meter
starts flashing, the display automati-
cally changes to the fuel reserve trip-
meter mode “TRIP F” and starts
counting the distance traveled from
that point. In that case, push the “SEL”
button to switch the display between
the various tripmeter, odometer, in-1. Neutral indicator light “ ”

Tips for reducing fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
Shift up swiftly, and avoid high en-
gine speeds during acceleration.
Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the en-
gine.
Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).
EAU16842
Engine break-inThere is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the fol-
lowing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that
might result in engine overheating
must be avoided.
EAU17094
0–1000 km (0–600 mi)
Avoid prolonged operation above 7000
r/min. NOTICE: After 1000 km (600
mi) of operation, the engine oil must
be changed and the oil filter car-
tridge or element replaced.
[ECA10303]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 8400
r/min.1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.
NOTICE
ECA10311
Keep the engine speed out of
the tachometer red zone.
If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-
cle.

WARNING
EWAT1041
Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.
Place a thick rag, like a towel, over the radiator cap, and then slowly rotate the cap counterclockwise to the
detent to allow any residual pressure to escape. When the hissing sound has stopped, press down on the cap
while turning it counterclockwise, and then remove the cap.TIPIf coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended cool-
ant as soon as possible.
Wait until the
engine has cooled.
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.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
There is
leakage.
There is
no leakage.
