12 Resetting the traction control sys-
tem
The traction control system will auto-
matically disable when:

the front wheel or rear wheel
comes off the ground while riding.

excessive rear wheel spin is de-
tected while riding.

either wheel is rotated with the key
turned to “ON” (such as when per-
forming maintenance).
If the traction control system is dis-
abled, both the “ ” indicator light and
the “ ” warning light will come on.
Should this occur, try resetting the sys-
tem as follows. 1. Stop the vehicle and turn the key to “OFF”.
2. Wait a few seconds and then turn the key back to “ON”.
3. The “ ” indicator light should turn off and the system be enabled.
TIPIf the “ ” indicator light remains on af-
ter resetting, the vehicle may still be rid-
den; however, have a Yamaha dealercheck the vehicle as soon as possible.
4. Have a Yamaha dealer check the vehicle and turn off the “ ” warn-
ing light.
EAU76401
Quick shift systemThe quick shift system (QS) allows for
full-throttle, clutch lever-less, electroni-
cally-assisted upshifts. When the shift
switch detects motion in the shift pedal
(page 4-14), engine power and drive
torque are momentarily adjusted to al-
low 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 2300
r/min or higher, and only when ac-
celerating.

It does not operate when the clutchlever is pulled.

Hazard switch “ ”
With the key in the “ON” or “ ” posi-
tion, use this switch to turn on the haz-
ard lights (simultaneous flashing of all
turn signal lights).
The hazard lights are used in case of
an emergency or to warn other drivers
when your vehicle is stopped where it
might be a traffic hazard.NOTICE
ECA10062
Do not use the hazard lights for an
extended length of time with the en-
gine not running, otherwise the bat-tery may discharge.

Coolant temperature warning light
“”
This warning light comes on if the en-
gine overheats. If this occurs, stop the
engine immediately and allow the en-
gine to 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.
NOTICE
ECA10022
Do not continue to operate the en-gine if it is overheating.TIP
For radiator-fan-equipped vehi-
cles, the radiator fan(s) automati-
cally switch on or off according to
the coolant temperature in the ra-
diator.

If the engine overheats, see page7-40 for further instructions.
EAU73171
Engine trouble warning light “ ”
This warning light comes on if a prob-
lem is detected in the engine or other
vehicle control system. If this occurs,
have a Yamaha dealer check the
on-board diagnostic system.
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 vehicle.
EAU69891
ABS warning light “ ”
In normal operation, this warning light
comes on when the key is turned to
“ON”, and goes off after traveling at a
speed of 10 km/h (6 mi/h) or higher.
If the ABS warning light:
does not come on when the key is
turned to “ON”

comes on or flashes while riding

does not go off after traveling at a
speed of 10 km/h (6 mi/h) or higher
The ABS may not work correctly. If any
of the above occurs, have a Yamaha
dealer check the system as soon as
possible. (See page 4-15 for an expla-
nation of the ABS.)WARNING
EWA16041
If the ABS warning light does not go
off after traveling at a speed of 10
km/h (6 mi/h) or higher, or if the
warning light comes on or flashes
while riding, the brake system re-
verts to conventional braking. If ei-
ther of the above occurs, or if the
warning light does not come on at

EAU77001
Traction control system indicator
light “ ”
In normal operation, this indicator light
flashes when traction control has en-
gaged.
When the traction control system has
been turned off (page 3-1), this indica-
tor light will come on.
If the traction control system becomes
disabled while riding, this indicator light
and the engine trouble warning light will
come on.
EAU76411
Quick shift indicator light “ ”
When the key is turned to “ON”, the
quick shift system (page 3-3) turns on
and this indicator light comes on.
If a problem is detected in the quick
shift system, this light will turn off and
the quick shift system will be unavail-
able. Have a Yamaha dealer check the vehicle.
EAU73120
Immobilizer system indicator light
“”
When the key is turned to “OFF” and 30
seconds have passed, the indicator
light will flash steadily to indicate the im-
mobilizer 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 time
s, this could becaused 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.

Eco indicator
This indicator comes on when the vehi-
cle is being operated in an environmen-
tally friendly, fuel-efficient manner. The
indicator goes off when the vehicle is
stopped.

Avoid high engine speeds during
acceleration.

Travel at a constant speed.

Select the transmission gear that
is appropriate for the vehiclespeed.

3. Start the engine by sliding the switch toward “ ”.
If the engine fails to start, release
the start/engine stop switch, wait a
few seconds, and then try again.
Each starting attempt should be as
short as possible to preserve the

EAU19653
Checking the spark plugsThe spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
The porcelain insulator around the cen-
ter electrode of each spark plug should
be a medium-to-light tan (the ideal color
when the vehicle is ridden normally),
and all spark plugs installed in the en-
gine should have the same color. If any
spark plug shows a distinctly different
color, the engine could be operating im-
properly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode
erosion and excessive carbon or other
deposits, it should be replaced.
