5B410012Engine oil and oil filter cartridgeCheck 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. 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.3. Lift the cargo bed up. (See page 4-27 forcargo bed lifting and lowering proce-
dures.)
4. Remove the engine oil dipstick, and then wipe it off with a clean rag.

5. Insert the dipstick completely into the oil filler hole, and then remove it again to
check the oil level. TIPThe engine oil should be between the mini-
mum and maximum level marks.1. Maximum level mark 2. Minimum level mark
3. Oil filler hole
6. If the engine oil is at or below the mini- mum level mark, remove the right rear
panel by removing the quick fastener
screws and bolts, and then add sufficient
oil of the recommended type to raise it to
the correct level.1. Right rear panel 2. Quick fastener screw (× 4)
3. Bolt ( × 2)7. Insert the dipstick completely into the oil
filler hole, and then install the right rear
panel by installing the bolts and the quick
fastener screws.
8. Lower the cargo bed.

NOTICE●
In order to prevent clutch slippage
(since the engine oil also lubricates
the clutch), do not mix any chemical
additives with oil. Do not use oils with
a diesel specification of “CD” or oils
of a higher quality than specified. In
addition, do not use oils labeled “EN-
ERGY CONSERVING II” or higher.
●
Make sure that no foreign material en-
ters the crankcase.
12. Start the engine, and then let it idle for several minutes while checking it for oil
leakage. If oil is leaking, immediately turn
the engine off and check for the cause.
13. Turn the engine off, wait at least 10 min- utes, and then check the oil level and cor-
rect it if necessary.
14. Install the right rear panel by installing the bolts and the quick fastener screws. 15. Lower the cargo bed.1XP7C_EE.book Page 14 Monday, June 9, 2014 5:17 PM

5B410015CoolantThe coolant level should be checked before
each ride.
Checking the coolant level 1. Park the vehicle on a level surface.
2. Check the coolant level in the coolant
reservoir when the engine is cold as the
coolant level varies with engine tempera-
ture. TIPThe coolant should be between the minimum
and maximum level marks.
1. Coolant reservoir cap
2. Maximum level mark 3. Minimum level mark3. If the coolant is at or below the minimum level mark, remove the coolant reservoir
cap, add coolant to the maximum level
mark, install the reservoir cap.
Coolant reservoir capacity
(up to the maximum level mark): 0.28 L (0.30 US qt, 0.25 Imp.qt)

5B410016Cleaning the air filter elementThe 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. Doing so would allow
unfiltered air to enter, causing rapid en-
gine wear and possible engine damage.
Additionally, the fuel injection system
would be affected, resulting in poor engine
performance and possible overheating.
1. Remove the center passenger seat cush-
ion. (See page 4-18 for seat cushion re-
moval and installation procedures.)
2. Remove the air filter case cover by un- hooking the holders.1. Air filter case cover holder ( × 6)

Engine overheating
Wait for the engine to cool before removing the radiator cap. WARNING! If the engine is not
cool when removing the radiator cap, hot fluid and steam could blow out under pressure
and burn you. Place a thick rag over the cap and remove the cap slowly to allow any remaining
pressure to escape.TIPIf it is difficult to get the recommended coolant , tap water can be used temporarily, provided that
it is changed to the recommended coolant as soon as possible.Wait until the
engine has cooled.
Check the coolant level in the
coolant reservoir and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See TIP.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and/or repair the cooling system.
