EBU35061Selecting the drive modeThe vehicle handles differently in each of the drive modes: “2WD”, “4WD” and “DIFF LOCK”. For
example, the vehicle requires more effort to turn in “DIFF LOCK” than in “2WD”. Always stop the
vehicle before changing the position of th e On-Command drive knob. The drive mode icon
changes according to the selected drive mode. The drive mode icon and the “DIFF LOCK” indi-
cator light come on as follows:
Knob position Indication Drive mode
(none)
“2WD” (two-wheel drive): Drive power is supplied to the rear
wheels only.
“4WD” (four-wheel drive): Drive power is supplied to the
front and rear wheels.
“DIFF LOCK” (four-wheel drive with the differential gear
locked): Drive power is supplied to the front and rear wheels
and the differential gear is locked.
Unlike in four-wheel drive, all wheels turn at the same
speed.

TIPWhen the knob is set to “DIFF LOCK” or “4WD ”, the drive mode icon and the indicator light
will flash until the differential gear is completely locked or unlocked.
 Turning the steering wheel back and forth will help the differential gear lock to engage or dis-
engage.
 To protect the drivetrain from damage, vehicle speed is limited until the differential gear lock
has properly transitioned. UB0F7AE0.book Page 11 Monday, November 6, 2017 2:30 PM

5. Follow steps 2–9 of the “To change theengine oil” section for the oil draining pro-
cedure.
6. Remove the oil filter cartridge with an oil filter wrench. Make sure the O-ring is re-
moved together with the oil filter car-
tridge. If the O-ring remains attached to
the crankcase, oil leakage may occur.
TIPAn oil filter wrench is available from a Yamaha
dealer. 7. Apply a light coat of clean engine oil to
the O-ring of the new oil filter cartridge.TIPMake sure that the O-ring is properly seated.

EBU35121Checking the spark plugsThe spark plug is an important engine com-
ponent which should be periodically
checked, preferably by a Yamaha dealer.
Since heat and deposits will cause any spark
plug to slowly erode, the spark plugs should
be removed and checked in accordance with
the periodic maintenance chart for the emis-
sion control system. In addition, the condition
of the spark plugs can reveal the condition of
the engine.
The porcelain insulator around the center
electrode of each spark plug should be a me-
dium-to-light tan color (the ideal color when
the vehicle is ridden normally), and all spark
plugs installed in the engine should have a
similar color. If any spark plug shows a dis-
tinctly different color, the engine could be op-
erating improperly. Do not attempt to
diagnose such problems yourself. Instead,
have a Yamaha dealer check the vehicle. If a spark plug shows signs of electrode ero-
sion and excessive carbon or other deposits,
it should be replaced.
Before installing a spark plug, the spark plug
gap should be measured with a wire thick-
ness gauge and, if necessary, adjusted to
specification.
Specified spark plug:

EBU36620Brake light switchThe brake light, which is activated by the
brake pedal, should come on just before
braking takes effect. Since the brake light
switch is a component of the YCC-S system,
it must be adjusted by a Yamaha dealer, who
has the necessary professional knowledge
and experience.EBU35930Cable inspection and lubrication
WARNING
EWB03380Damaged cables could restrict operation,
which may cause an accident or injury. In-
spect control cables frequently and re-

result when the outer covering of control
cables becomes damaged. Cables can
also become frayed or kinked.
