EAU76825
Stop and Start SystemThe Stop and Start System stops the
engine automatically when the vehicle
is stopped in order to prevent noise,
control exhaust emissions, and reduce
fuel consumption.
When the rider turns the throttle grip
slightly, the engine restarts automati-
cally and the vehicle starts off.NOTICE
ECA23961
When parkin g the vehicle or leavin g
the vehicle unatten ded , be sure to
turn the main switch off. If the Stop
an d Start System is left turne d on,
the battery coul d become dis- char
ged an d it may not be possi ble
to restart the en gine due to insuffi-
cient battery volta ge.
TIP Although the engine normally
stops at the same time as the ve-
hicle, there may be a delay when
operating the vehicle under 10
km/h, such as in heavy traffic.
 If you think the battery voltage is
low because the engine cannot be
started using the starter switch or
for some other reason, do not turn
on the Stop and Start System.
 Have a Yamaha dealer check the
battery at the intervals specified in
the periodic maintenance chart.

V-
belt replacement tripmeter “V-
Belt Trip”
The V-belt replacement tripmeter
shows the distance traveled since the
V-belt was last replaced.
The V-belt replacement indicator “V-
Belt” will flash every 18000 km (10500
mi) to indicate that the V-belt should be
replaced.
After replacing the V-belt, reset the V-
belt replacement indicator and the V-
belt replacement tripmeter. To reset
them both, select the V-belt replace-
ment tripmeter, and then push the
“TRIP” switch for three seconds. While the V-belt replacement tripmeter
is flashing, push the “TRIP” switch for
15 to 20 seconds. Release the “TRIP”
switch, and the V-belt trip value will re-
set to zero.
TIPIf the V-belt is replaced before the V-
belt replacement indicator comes on
(i.e., before the periodic V-belt replace-
ment interval has been reached), the V-
belt replacement tripmeter must be re-
set for the V-belt replacement indicator
to come on at the correct time.Information

This function calculates the average
fuel consumption since it was last re-
set.
The average fuel consumption can be
displayed as either “Consump-

tion/Average_ _._ L/100 km” or
“Consumption/Average_ _ _._ MPG”
(for the UK). 
“Consumption/Average_ _._
km/L”: The average distance that
can be traveled on 1.0 L of fuel is
shown.
 “Consumption/Average_ _._
L/100 km”: The average amount
of fuel necessary to travel 100 km
is shown.
 “Consumption/Average_ _ _._
MPG” (for the UK): The average
distance that can be traveled on
1.0 Imp.gal of fuel is shown.
