“2WD/4WD/DIFF LOCK” is set to
“DIFF LOCK” or “4WD”, the indicator
“ ” and the indicator light “DIFF. LOCK”
will flash until the differential gear is com-
pletely locked or unlocked. If the indicator

the differential is not completely locked or
unlocked. In this case, start moving to al-
low time for the differential to lock or un-
lock.

EVU00430Final gear oilMake sure the final gear oil is at the specified
level. Add oil as necessary. (See page 8-15
for details.)
If desired, an SAE 80W-90 hypoid gear oil
may be used for all conditions.TIPGL-4 is a quality and additive rating; GL-5 or
GL-6 rated hypoid gear oils may also be used.EVU00440Differential gear oilMake sure the differential gear oil is at the
specified level. Add oil as necessary. (See
page 8-17 for details.)
EVU00450Accelerator pedalCheck to see that the accelerator pedal oper-
ates correctly. It must operate smoothly and
spring back to the idle position fully when re-
leased. Have a Yamaha dealer repair as nec-
essary for proper operation.EVU00460Seat beltsMake sure that the seat belts are not frayed,
torn, stretched, or damaged. The seat belts
must move smoothly when pulled out and re-
tract on its own when released. The seat belts
must also lock up when quickly pulled out.
The latch plate should click securely into the
buckle and release when the release button is
pushed firmly. Wash off any dirt or mud that
could affect operation. Have a Yamaha dealer
repair as necessary for proper operation.
Recommended oil:
SAE 80 API GL-4 Hypoid gear oil
Recommended oil: SAE 80 API GL-4 Hypoid gear oil

5B410009On-Command drive knobThe 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 the On-Command drive knob. The meter display changes
according to the selected drive mode. The different drive indicators, and the differential gear lock
indicator light “DIFF. LOCK” come on as follows:Knob position Indication Drive mode
No indicator light. “2WD” (two-wheel drive): Power is supplied to the rear wheels.
“4WD” (four-wheel drive): Power is supplied to the rear and
front wheels.
“DIFF LOCK” (four-wheel drive with the differential gear
locked): Power is supplied to the rear and front 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 differential gear lock indicator and indi-
cator light will flash until the differential gear is completely locked or unlocked.
●
When the indicator and indicator light are flashing, turning the steering wheel back and forth
will help the differential gear lock to engage or disengage.
●
Riding before the differential gear is properly engaged or disengaged (e.g., when the indica-
tor and indicator light are flashing) will cause the vehicle speed to be limited until the differ-
ential gear is completely engaged or disengaged.

Wear eye protection when operating or riding
the vehicle to reduce the risk of a serious ac-
cident or injury. Eye protection, such as a face
shield or goggles, may reduce the risk of for-
eign material getting in your eyes and help
prevent loss of vision.
Practice for new Yamaha Viking users
You should become familiar with the perfor-
mance characteristics of the vehicle in a large,
flat area that is free of obstacles and other ve-
hicles. Practice controlling the accelerator
pedal, brakes, steering, and drive select lever.
Drive at slow speeds with gradual accelera-
tion and turning. Practice smooth throttle ap-
plication. Practice slowing down before
turning. Practice maintaining a steady throttle
through the turn. Avoid higher speeds until
you are thoroughly familiar with the operation
of your vehicle. Remember, driving aggres-
sively or making abrupt maneuvers even on
flat, open areas can cause side rollovers.Become familiar with the way the vehicle feels
in low and high ranges, first in two-wheel drive
“2WD” and then in four-wheel drive “4WD”
and four-wheel drive with the differential
locked “DIFF LOCK”. Steering may take more
effort in four-wheel drive with the differential
locked “DIFF LOCK”. Also practice driving in
reverse.
Take the time to learn basic operation of the
vehicle before attempting more difficult ma-
neuvers.1XP7C_EE.book Page 15 Monday, June 9, 2014 5:17 PM
