5B410012Engine oil and oil filter cartridge
Check engine oil level before each operation.
In addition, change the oil and the oil filter car-
tridge at the intervals specified in the periodic
maintenance and lubrication chart.
To check the engine oil level1. Park the vehicle on a level surface.
2. Remove the console. (See page 8-9 for console removal and installation proce-
dures.)
3. Check the engine oil level on a cold en-
gine. TIPIf the engine was started before checking the
oil level, be sure to warm up the engine suffi-
ciently, and then wait at least 10 minutes until
the oil settles for an accurate reading.4. Remove the engine oil dipstick, and thenwipe it off with a clean rag.

Changing the coolant
The coolant must be changed by a Yamaha
dealer at the intervals specified in the periodic
maintenance and lubrication chart.
Adding water instead of coolant lowers the
antifreeze content of the coolant. If water is
used instead of coolant, have a Yamaha deal-
er check the antifreeze content of the coolant
as soon as possible.
The radiator fan is automatically switched on
or off according to the coolant temperature in
the radiator.NOTICEMix antifreeze with distilled water only.
However, if distilled water is not available,
soft water may be used for refilling.If your vehicle overheats, see page 8-63 for
instructions.
EVU00740Axle boots
Check the axle boots for holes or tears.
If any damage is found, have them replaced
by a Yamaha dealer.1. Front axle boot (× 2 each side)

14. Insert the projections on the air filter casecover into the holders on the air filter
case, and then install the air filter case
cover by hooking the holders onto the
cover.1. Projection ( × 2) 2. Holder ( × 2)15. Install the air intake duct shroud by in-
stalling the quick fastener screws.
16. Close the hood. The air filter element should be cleaned every
20–40 hours. It should be cleaned and lubri-
cated more often if the vehicle is operated in
extremely dusty areas. Each time air filter ele-
ment maintenance is performed, check the air
inlet to the air filter case for obstructions.
Check the air filter element rubber joint to the
throttle body and manifold fittings for an air-
tight seal. Tighten all fittings securely to avoid
the possibility of unfiltered air entering the en-
gine.
NOTICENever operate the engine with the air filter
element removed. This will allow unfiltered
air to enter, causing rapid engine wear and
possible engine damage. Additionally, op-
eration without the air filter element will af-
fect the fuel injection system with
subsequent poor performance and possi-
ble engine overheating.

WARNING
Improper maintenance can result in loss of
braking ability. Observe these precautions:●
Insufficient brake fluid may allow air to
enter the brake system, reducing brak-
ing performance.
●
Clean the filler cap before removing.
Use only DOT 4 brake fluid from a
sealed container.
●
Use only the specified brake fluid; oth-
erwise, the rubber seals may deterio-
rate, causing leakage.
●
Refill with the same type of brake fluid.
Adding a brake fluid other than DOT 4
may result in a harmful chemical reac-
tion.
●
Be careful that water does not enter
the brake fluid reservoir when refilling.
Water will significantly lower the boil-
ing point of the fluid and may result in
vapor lock.
NOTICEBrake fluid may damage painted surfaces
or plastic parts. Always clean up spilled
fluid immediately.As the brake pads wear, it is normal for the
brake fluid level to gradually go down. A low
brake fluid level may indicate worn brake
pads and/or brake system leakage; therefore,
be sure to check the brake pads for wear and
the brake system for leakage. If the brake fluid
level goes down suddenly, have a Yamaha
dealer check the cause before further riding.EVU00860Brake fluid replacement
Complete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during periodic maintenance or
when they are damaged or leaking.●
Replace the oil seals every two years.
●
Replace the brake hoses every four years.
