The odometer shows the total distance
traveled by the vehicle.
The tripmeters show the distance trav-
eled since they were last reset.
The fuel reserve tripmeter shows the
distance traveled since the fuel level
warning light came on.
For Europe:
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 “L/100 km” or “km/L”, aver-
age fuel consumption mode “AVE_ _._
L/100 km” or “AVE_ _._ km/L” and oil
change tripmeter mode “OIL TRIP” in
the following order:
ODO → TRIP 1 → TRIP 2 → L/100 km
or km/L → AVE_ _._ L/100 km or AVE_
_._ km/L → OIL TRIP → ODO
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- stantaneous fuel consumption and av-
erage fuel consumption modes in the
following order:
TRIP F
→ L/100 km or km/L → AVE_
_._ L/100 km or AVE_ _._ km/L → OIL
TRIP → ODO → TRIP 1 → TRIP 2 →
TRIP F
To reset a tripmeter, select it by push-
ing the “SEL” button, and then push
the “RES” button for at least one sec-
ond.
If you do not reset the fuel reserve trip-
meter manually, it resets itself auto-
matically and the display returns to the
prior mode after refueling and traveling
5 km (3 mi).
For the UK:
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 “MPG”, “L/100 km” or
“km/L”, average fuel consumption
mode “AVE_ _._ MPG”, “AVE_ _._
L/100 km” or “AVE_ _._ km/L” and oil
change tripmeter mode “OIL TRIP” in
the following order:
ODO → TRIP 1 → TRIP 2 → MPG,
L/100 km or km/L → AVE_ _._ MPG,
AVE_ _._ L/100 km or AVE_ _._ km/L →
OIL TRIP → ODO
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

“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

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
you to adjust the brightness of the
indicator light.

Engine oil an d oil filter car-
tri dge
The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the en gine oil level
1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Wait a few minutes until the oil set- tles, and then check the oil level
through the engine oil level check
window located at the bottom-
right side of the crankcase.
TIP
The engine oil should be between the
minimum and maximum level marks.

9. Install the engine oil drain bolt and its new gasket, and then tighten
the bolt to the specified torque.
TIP
Install the new gasket as shown.
10. Refill with the specified amount of the recommended engine oil, and
then install and tighten the oil filler
cap.
TIP
Be sure to wipe off spilled oil on any

11. Install the cowling by installing the bolts.
12. Start the engine, and then let it idle for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.
TIP
After the engine is started, the engine
oil pressure warning light should go off.
NOTICE

If the oil pressure warnin g li ght flick-
ers or remains on even if the oil level
is correct, imme diately turn the en-
g ine off an d have a Yamaha dealer
check the vehicle.
13. Turn the engine off, wait a few minutes until the oil settles, and
then check the oil level and cor-
rect it if necessary.

Coolant
The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU38176To check the coolant level1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.
TIP
zThe coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
z Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level in the
coolant reservoir.
TIP
The coolant should be between the
minimum and maximum level marks.
