d Car bon Monoxi de Poisonin g
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing
carbon monoxide can cause head-
aches, dizziness, drowsiness, nausea,
confusion, and eventually death.
Carbon Monoxide is a colorless, odor-
less, tasteless gas which may be pres-
ent even if you do not see or smell any
engine exhaust. Deadly levels of car-
bon monoxide can collect rapidly and
you can quickly be overcome and un-
able to save yourself. Also, deadly lev-
els of carbon monoxide can linger for
hours or days in enclosed or poorly
ventilated areas. If you experience any
symptoms of carbon monoxide poi-
soning, leave the area immediately, get
fresh air, and SEEK MEDICAL TREAT-
MENT.  Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rap-
idly reach dangerous levels.
 Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports. 
Do not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors.
Loa din g
Adding accessories or cargo to your
motorcycle can adversely affect stabil-
ity and handling if the weight distribu-
tion of the motorcycle is changed. To
avoid the possibility of an accident, use
extreme caution when adding cargo or
accessories to your motorcycle. Use
extra care when riding a motorcycle
that has added cargo or accessories.
Here, along with the information about
accessories below, are some general
guidelines to follow if loading cargo to
your motorcycle:
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloa ded vehicle
coul d cause an acci dent. When loading within this weight limit,
keep the following in mind:
 Cargo and accessory weight
should be kept as low and close to
the motorcycle as possible. Se-
curely pack your heaviest items as
close to the center of the vehicle
as possible and make sure to dis-
tribute the weight as evenly as
possible on both sides of the mo-
torcycle to minimize imbalance or
instability.
 Shifting weights can create a sud-
den imbalance. Make sure that
accessories and cargo are se-
curely attached to the motorcycle
before riding. Check accessory
mounts and cargo restraints fre-
quently.
• Properly adjust the suspension for your load (suspension-ad-
justable models only), and
check the condition and pres-
sure of your tires.
• Never attach any large or heavy items to the handlebar, front
fork, or front fenders. These
items, including such cargo as
sleeping bags, duffel bags, or

Oil level warnin g li ght “ ”
This warning light comes on when the
engine oil level is low. To prevent en-
gine damage, replenish the engine oil
as soon as possible.
Even if the oil level is sufficient, the
warning light may flicker when riding
on a slope or during sudden accelera-
tion or deceleration, but this is not a
malfunction. If a problem is detected in
the oil level detection circuit, the oil lev- el warning light will flash repeatedly. If
this occurs, have a Yamaha dealer
check the vehicle.
TIPWhen the vehicle is turned on, this light
will come on for a few seconds and
then go off. If the light does not come
on, or if the light remains on after con-
firming that the oil level is correct (see
page 6-11), have a Yamaha dealer
check the vehicle.

This indicator light can be set to come
on and go off at select engine speeds.
(See page 3-16.)TIPWhen the vehicle is turned on, the light
should come on for a few seconds and

EAU73120
Immo bilizer system in dicator
li g ht “ ”
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.
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.

This indicator comes on when the vehi-
cle is being operated in an environ-
mentally friendly, fuel-efficient manner.
The indicator goes off when the vehicle
is stopped.TIPConsider the following tips to reduce
fuel consumption:  Avoid high engine speeds during
acceleration. 
Travel at a constant speed.
 Select the transmission gear that
is appropriate for the vehicle
speed.

The ABS performs a self-check
when you first start off. During this
time a clicking noise from the hy-
draulic unit may be audible, and if
the brake lever or brake pedal is
applied a vibration can be felt, but
this is not a malfunction.
 The brake system will revert to a
conventional brake system in case
of ABS malfunction.
NOTICE
ECA20100
Be careful not to damag e the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of the
ABS will result.
EAU76315
Traction control systemThe traction control system (TCS)
helps maintain traction when acceler-
ating on slippery surfaces, such as un-
paved or wet roads. If sensors detect
that the rear wheel is starting to slip
(uncontrolled spinning), the traction
control system assists by regulating
engine power as needed until traction
is restored.
WARNING
EWA15433
The traction control system is not a
su bstitute for rid ing appropriately
for the con ditions. Traction control
cannot prevent loss of traction due
to excessive speed when entering
turns, when acceleratin g har d at a
sharp lean an gle, or while brakin g,
an d cannot prevent front wheel slip-
pin g. As with any vehicle, approach
surfaces that may be slippery with
caution an d avoi d especially slip-
pery surfaces.
