OPERATION
EBU19902Read the Owner’s Manual carefully before riding
the ATV. If there is a control or function you do not
understand, ask your Yamaha dealer.
WARNING
EWB00632Read the Owner’s Manual carefully to become
familiar with all controls in order to help pre-
vent any loss of control, which could cause an
accident or injury. EBU30564Starting the engineThis model is equipped with an ignition circuit cut-
off system. To enable starting one of the following
conditions must be met:
The drive select lever is in the neutral or park po-
sition.
 The rear brake lever or brake pedal is applied.TIPIt is recommended to shift into neutral or park and
apply the rear brake when starting the engine.
NOTICEECB00151See the “Engine break-in” section on page 7-4
prior to operating the engine for the first time. To start the engine
1. Turn the key to “ ” (on) and the engine stop switch to “ ” (run).
The coolant temperature warning light and
the engine trouble warning light should
come on for a few seconds, then go off.
 For EPS-equipped models, the electric
power steering warning light should come
on and stay on until the engine is started.NOTICEECB00826To avoid possible damage, do not operate the
ATV if a warning light does not work as de-
scribed above. 2. Apply the brake pedal, then shift the drive se-
lect lever into the neutral or park position. The
corresponding indicator light should come

EBU23473CoolantThe coolant level should be checked regularly. In
addition, the coolant must be changed at the in-
tervals specified in the periodic maintenance
chart.TIPIf genuine Yamaha coolant is not available, use an
ethylene glycol antifreeze containing corrosion in-
hibitors for aluminum engines and mix with dis-
tilled water at a 1:1 ratio.
NOTICEECB02190Mix antifreeze with distilled water only. Howev-
er, if distilled water is not available, soft water
may be used for refilling. Do not use hard water
or salt water since they are harmful to the en-
gine. EBU2712ATo check the coolant level1. Park the ATV on a level surface.TIPThe coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture. 2. Check the coolant level in the coolant reser- voir.TIPThe coolant should be between the minimum and
maximum level marks.
Recommended coolant:YAMALUBE coolant
Coolant quantity: Coolant reservoir (up to full level):0.25 L (0.26 US qt, 0.22 Imp.qt)
Radiator (including all routes): 1.32 L (1.40 US qt, 1.16 Imp.qt)

93. If the coolant is at or below the minimum level
mark, remove panel C to access the coolant
reservoir. (See page 9-10.)
4. Remove the coolant reservoir cap. WARNING! Remove only the coolant res-
ervoir cap. Never attempt to remove the
radiator cap when the engine is hot.
[EWB02672]
5. Add coolant to the maximum level mark, in-stall the reservoir cap, and then install the
panel. NOTICE: If coolant is not available,
use distilled water or soft tap water in-
stead. Do not use hard water or salt water
since they are harmful to the engine. If wa-
ter has been used instead of coolant, re-
place it with coolant as soon as possible,
otherwise the cooling system will not be
protected against frost and corrosion. If
water has been added to the coolant, have
a Yamaha dealer check the antifreeze con-

To change the coolant
WARNING
EWB01891Wait for the engine and radiator to cool before
removing the radiator cap. You could be
burned by hot fluid and steam blown out under
pressure. Always place a thick rag over the cap
when opening. Allow any remaining pressure
to escape before completely removing the cap. 1. Park the ATV on a level surface.
2. Remove the front carrier and panel F. (See page 9-10.)
3. Remove the radiator cap. 4. Remove panels D and E. (See page 9-10.)
5. Place a container under the engine, and then
remove the coolant drain bolt and its gasket.
(Use a trough or a similar object as shown to
prevent coolant from spilling on the footrest.)

96. Remove the coolant reservoir cap.
7. Disconnect the coolant reservoir hose on the
coolant reservoir side, and then drain the
coolant from the coolant reservoir. 8. After draining the coolant, thoroughly flush
the cooling system with clean tap water.
9. Install the coolant drain bolt and its new gas- ket, and then tighten the bolt to the specified
torque.
10. Connect the coolant reservoir hose.
11. Pour the recommended coolant into the res- ervoir to the maximum level mark, and then
install the reservoir cap.

12. Pour the recommended coolant into the radi-
ator until it is full, and then install the radiator
cap.
13. Start the engine, let it idle for several minutes, and then turn it off.
TIPWhile the engine is idling, check the cooling sys-
tem for leaks. 14. When the engine is cool, remove the radiatorcap to check the coolant level in the radiator.
If it is low, add sufficient coolant until it reach-
es the top of the radiator, and then install the
radiator cap.
15. Install the panels and the front carrier.EBU37113Cleaning the air filterThe main air filter element and sub air filter ele-
ment should be cleaned every 20–40 hours of en-
gine operation. When servicing the air filter
elements, check the air filter case inlet for obstruc-
tions. Check the air filter case rubber joint to the
throttle body and the rubber joint manifold fittings
for an air-tight seal. Tighten all fittings securely to
avoid the possibility of unfiltered air entering the
engine.
TIP Replace the air filter elements if damaged.
 Service the air filter more frequently if you often
ride in wet or dusty areas.
 There is a check hose at the bottom of the air fil-
ter case. If dust or water collects in this hose,
empty the hose and clean the air filter case and
air filter elements. 1. Park the ATV on a level surface.
2. Remove the seat. (See page 5-18.)
3. Remove the air filter case cover by unhooking
the air filter case cover holders.1. Air filter case check hose

WARNING
EWB02291Wait for the engine and radiator to cool before removing the radiator cap. You could be burned by
hot fluid and steam blown out under pressure. Always put a thick rag over the cap when opening.
Allow any remaining pressure to escape before completely removing the cap. TIP
Tap water can be used in an emergency. Change to the recommended coolant as soon as possible.
 The engine will tend to overheat if the radiator is caked with mud, or if the ATV is overloaded. Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
