“AVE_ _._ MPG” (for the UK): The
average distance that can be trav-
eled on 1.0 Imp. gal of fuel is
shown.
To switch between the average fuel
consumption displays, push the “SEL”
button for one second.
To reset the average fuel consumption
display, push the “RES” button for at
least one second.
TIP
After resetting the average fuel con-
sumption display, “_ _._” is shown until
the vehicle has traveled 1 km (0.6 mi).
Oil chan ge tripmeter
The oil change tripmeter shows the
distance traveled since it was last reset
(i.e., since the last oil change).
The oil change indicator “OIL” will flash
at the initial 1000 km (600 mi), then at
5000 km (3000 mi) and every 5000 km
(3000 mi) thereafter to indicate that the
engine oil should be changed.
After changing the engine oil, reset the
oil change tripmeter and the oil change
indicator. To reset them both, select
the oil change tripmeter, and then push
the “RES” button for one second.
Then, while “OIL” and the oil change tripmeter are flashing, push the “RES”
button for three seconds. The oil
change indicator will be reset.
If the engine oil is changed before the
oil change indicator comes on (i.e., be-
fore the periodic oil change interval has
been reached), the oil change tripmeter
must be reset for the next periodic oil
change to be indicated at the correct
time.
Shift timin
g in dicator li ght
The shift timing indicator light has four
settings which can be adjusted. z Flashing pattern: this function al-
lows you to choose whether or not
the indicator light will come on and
whether it should flash or stay on
when activated.
z Activation point: this function al-
lows you to select the engine
speed at which the indicator light
is activated.
z Deactivation point: this function
allows you to select the engine
speed at which the indicator light
is deactivated.
z Brightness: this function allows

EAU16842
En gine break-in
There 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 en gine oil must
b e chan ged an d the oil filter car-
tri dge or element replace d.
[ECA10303]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 8400
r/min.
1600 km (1000 mi) an d b eyon d
The vehicle can now be operated nor-
mally.
NOTICE
ECA10311
z Keep the en gine spee d out of
the tachometer red zone.
z If any en gine trou ble shoul d oc-
cur during the en gine break-in
period , imme diately have a
Yamaha dealer check the vehi-
cle.
EAU17214

When parking, stop the engine, and
then remove the key from the main
switch.

ans or chil dren are not likely to
touch them and b e burne d.
z Do not park on a slope or on soft
groun d, otherwise the vehicle
may overturn, increasin g the
risk of a fuel leak an d fire.
z Do not park near g rass or other
flammab le materials which
mi ght catch fire.
