EAU79481
Quick shift system
The 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.
TIP
The 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 spee d, when
d ownshiftin g, or if the quick shift
system is off.

4 When the vehicle is turned on, the light
will perform a circuit check (come on
for a few seconds and then go off).
If the warning light remains on after
confirming that the oil level is correct
(page 7-13), have a Yamaha dealer
check the vehicle.
TIP

Even if the oil level is sufficient, the
warning light may flicker when rid-
ing up or downhill, or during sud-
den acceleration or deceleration,
but this is not a malfunction.
 If a malfunction is detected, the oil
level warning light will flash re-
peatedly. Have a Yamaha dealer
check the vehicle.
EAU11369Fuel level warnin g lig ht “ ”
This warning light comes on when you
are low on fuel. When the fuel level
drops below approximately 3.4 L (0.90
US gal, 0.75 Imp.gal), the light will
come on to remind you to refuel as
soon as possible.
When the vehicle is turned on, the light
will perform a circuit check (come on
for a few seconds and then go off).
If the warning light does not come on
during the circuit check, or if the warn-
ing light remains on after refueling,
have a Yamaha dealer check the vehi-
cle.
TIP
If a malfunction is detected, the fuel
level warning light will flash repeatedly.
Have a Yamaha dealer check the vehi-
cle.
EAU72930Coolant temperature warnin g
li g ht “ ”
This warning light comes on if the en-
gine overheats. If this occurs, reduce
the load on the engine immediately. If

temperature display, stop the vehicle,
then stop the engine and let the engine
cool.
The electrical circuit of the warning
light can be checked by turning the key
to “ON”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come on
initially when the key is turned to “ON”,
or if the warning light remains on, have
a Yamaha dealer check the electrical
circuit.

4 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.
TIP
If 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.
3. If the engine starts, turn it off, and try starting the engine with the
standard keys.
4. If one or both of the standard keys do not start the engine, take the
vehicle and all 3 keys to a Yamaha
dealer to have the standard keys
re-registered.

Coolant temperature display
This display indicates the temperature
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 7-41.)
TIP
 When the vehicle is turned on, the
coolant temperature display is au-
tomatically selected. 
When the coolant temperature is
below 41 °C, “Lo” will be dis-
played.
Air intake temperature display
This display indicates the temperature
of the air drawn into the air intake duct.
Push the “RESET” button to switch the
display between the coolant tempera-
ture and the air intake temperature.
TIP
 When the coolant temperature
display is selected, “C” is dis-
played for one second, and then
the coolant temperature is dis-
played.
 When the air intake temperature
display is selected, “A” is dis-
played for one second, and then
the air intake temperature is dis-
played.
