NOTICE
ECA10022
Do not continue to operate the en-
gine if it is overheating.
TIP
Coolant temperature varies with
changes in the weather and en-
gine load.
The radiator fan will automatically
switch on or off according to the
coolant temperature.
If the engine overheats, see page
6-39 for further instruction.
Odometer and tripmeter display
The odometer and tripmeter display is
equipped with:
an odometer
two tripmeters
a fuel reserve tripmeter
Push the “SELECT” button to switch
between the odometer and the tripme-
ters in the following order:
ODO (odometer) → TRIP 1 (tripmeter)
→ TRIP 2 (tripmeter) → ODO (odome-
ter)When approximately 3.0 L (0.79 US
gal, 0.66 Imp.gal) of fuel remains in the
fuel tank, the display will automatically
change to the fuel reserve tripmeter
mode “F TRIP” and start counting the
distance traveled from that point. In
this case, push the “SELECT” button
to switch the display in the following
order:
F TRIP → ODO → TRIP 1 → TRIP 2 →
F TRIP
To manually reset a tripmeter, select it
with the “SELECT” button, and then
push the “RESET” button for two sec-
onds.
TIP
The fuel reserve tripmeter will re-
set automatically and disappear
after you have refueled and turned
the key to “OFF”.
The tripmeters will automatically
reset and continue counting after
999.9 is reached.
The odometer will lock at 199999
and cannot be reset.

TIP
To reset the average fuel con-
sumption, push the “RESET” but-
ton for two seconds. However, the
odometer and tripmeter display
must be set to “ODO”, otherwise
the tripmeter will be reset instead.
After resetting the average fuel
consumption, “_ _._” is shown un-
til the vehicle has traveled a suffi-
cient distance.
Instantaneous fuel consumption “C
INS”
Instantaneous fuel consumption can
be displayed in “km/L” or “L/100 km”,
or in “MPG” for the UK.
“km/L”: The distance that can be
traveled on 1.0 L of fuel under cur-
rent riding conditions.
“L/100 km”: The amount of fuel
necessary to travel 100 km under
current riding conditions.
“MPG”: The distance that can be
traveled on 1.0 Imp.gal of fuel un-
der current riding conditions.
TIP
If traveling at speeds under 10 km/h (6

Average speed “AVE SPEED”
Average speed wll be displayed in
“AVE SPEED_ _._ km/h”. For the UK,
when miles have been set, “AVE
SPEED __._ mph” will be displayed in-
stead.
 “AVE SPEED_ _._ km/h”: Your av-
erage traveling speed in kilome-
ters per hour.
“AVE SPEED_ _._ mph”: Your av-
erage traveling speed in miles per
hour.
TIP
The average speed display will re-
set automatically 4 hours after the
key was last turned to “OFF”.
To manually reset the average
speed display, push the “RESET”
button for two seconds. However,
the odometer and tripmeter dis-
play must be set to “ODO”, other-
wise the tripmeter will be reset
instead.

This function records the elapsed time
of your current trip, or since it was last
reset. Trip time is displayed in “_h
_min” (hours and minutes).
TIP
The trip time meter will automati-
cally reset 4 hours after the key
was last turned to “OFF”.
To manually reset the trip time me-
ter, push the “RESET” button for
two seconds. However, the
odometer and tripmeter display

Oil change trip meter “DIST SERV”
This function shows the distance trav-
eled since your last oil service. It will re-
set when the oil change indicator is
reset.Oil change indicator “OIL”
This indicator flashes (“OIL SERV”
message will also appear) to indicate
that the engine oil should be changed.
It will come on at the initial 1000 km
(600 mi) service interval, 2000 km
(1200 mi) after that, and every 3000 km
(1800 mi) thereafter. After changing the
engine oil, be sure to reset the oil
change indicator.
To reset the oil change indicator, make
sure the odometer and tripmeter dis-
play is set to “ODO”, then push the
“RESET” button for two seconds until
“OIL SERV” message flashes, and then
push and hold the “RESET” button for

TIP
If the engine oil is changed before the
oil change indicator comes on (i.e. be-
fore the set oil service interval has been
reached), the indicator must be reset
for the next oil change to be indicated
at the correct time. In this case, make
sure the odometer and tripmeter is set

the multi-function display, then push

TIP
The annual checks must be performed every year, except if a kilometer-
based maintenance, or for the UK, a mileage-based maintenance, is
performed instead.
From 30000 km (17500 mi), repeat the maintenance intervals starting from
6000 km (3500 mi).
Items marked with an asterisk should be performed by a Yamaha dealer as
they require special tools, data and technical skills.
