Quick shift systemThe quick shift system allows for full-
throttle, clutch lever-less upshifts.
When the shift switch detects motion
in the shift pedal, engine power and
drive torque are momentarily adjusted
to allow the upshift to occur.TIPThe quick shift system operates when
traveling at least 20 km/h (12 mi/h) with
an engine speed of 2000 r/min or high-
er, and only when accelerating. It does
not operate when the clutch lever is
pulled.NOTICE
ECA26260
To prevent drivetrain damag e, al-
ways use the clutch lever to shift
when ri din g at slow speed , when
d ownshiftin g, or if the quick shift
system is off.

Immo bilizer system in dicator li ght
When the key is turned to “OFF” and
30 seconds have passed, the indicator
light will flash steadily to indicate the
immobilizer system is enabled. After 24
hours have passed, the indicator light
will stop flashing, however the immobi-
lizer system is still enabled. The electrical circuit of the indicator
light can be checked by turning the key
to “ON”. The indicator light should
come on for a few seconds, and then
go off.
If the indicator light does not come on
initially when the key is turned to “ON”,
if the indicator light remains on, or if the
indicator light flashes in a pattern (if a
problem is detected in the immobilizer
system, the immobilizer system indica-
tor light will flash in a pattern), have a
Yamaha dealer check the vehicle.
TIPIf the immobilizer system indicator light
flashes in the pattern, slowly 5 times
then quickly 2 times, this could be
caused by transponder interference. If
this occurs, try the following.1. Make sure there are no other im- mobilizer keys close to the main
switch. Other immobilizer system
keys may cause signal interfer-
ence and prevent the engine from
starting.
2. Use the code re-registering key to start the engine.

of the coolant from 41 °C to 124 °C in
1 °C increments.
If the coolant temperature is between
117 and 124 °C, the coolant tempera-
ture display flashes and the coolant
temperature warning light comes on. If
this occurs, reduce the load on the en-
gine by riding at a moderate pace, at
low rpm, until the coolant temperature
goes down. If the temperature does
not go down, or if the message “HI”
flashes, stop the engine and let it cool.
(See page 7-42.)
TIP
When the vehicle is turned on, the
coolant temperature display is au-
tomatically selected.
