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

Become familiar with the way the vehicle han-
dles in the various drive modes. Start off with
two-wheel drive “2WD”, then four-wheel drive
“4WD”, and finally 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.TIPTake the time to learn basic operation of the
vehicle before driving at higher speeds or at-
tempting more difficult maneuvers.
Getting ready to ride
Perform the pre-operation checks on page
5-1. Follow the instructions on page 6-2 when
starting the engine.
Turning
Use care in turns — turning the steering wheel
too far or too fast can result in loss of control
or a rollover. Slow down before entering
turns. When making tight turns from a stand-
still or at slow speeds, avoid sudden or hard
acceleration. Driving aggressively or making
abrupt maneuvers even on flat, open areas
can cause side rollovers. Avoid sideways slid-
ing, skidding, or fishtailing (rear-wheel slid-
ing), and never do donuts. If you feel the
vehicle begin to slide sideways or the rear
wheels begin to slide during a turn, steer into
the direction of the slide, if possible, and
gradually let off the accelerator pedal to re-
gain directional control and avoid rollover. For
example, if you feel the back of the vehicle
start to slide to your right, steer to the right.

TIPYou may need to turn the steering wheel left
and right to help the differential lock into pla-
ce. 3. Stop the engine (turn the key to “ ”[off]).
4. With the brake pedal still being applied, set the parking brake.
5. Finally, get out of the vehicle and block
the front and rear wheels with rocks or
other objects.
Loading
Be aware that vehicle load includes the total
combined weight of the operator, passenger,
any installed accessories, and any luggage or
cargo brought on board or stored in the cargo
bed. Make sure that the gross vehicle weight
(vehicle load plus weight of the vehicle itself)
never exceeds 1025 kg (2260 lb). Vehicle loading can affect handling as well as
the recommended tire pressure. (See pages
6-12, 5-8.)
EBU36681Operation on different surfaces and
terrainsGo slowly and proceed with caution when op-
erating on an unfamiliar surface or terrain.
This vehicle may handle differently in certain
types of terrains or on certain surfaces. You
may come upon hidden rocks, bumps, or
holes without enough time to react. To avoid
loss of control or rollover, always be alert to
changing surfaces or terrain when operating
the vehicle.
Your Yamaha YXZ1000R has higher ground
clearance and other features to handle rug-
ged terrain, and as a result, can overturn in
situations where some vehicles may not.
Abrupt maneuvers or aggressive driving can
cause loss of control, including rollovers –

8. Check for oil leakage. If oil leakage isfound, check for the cause.EBU36061Differential gear oilCheck the oil level and change the differential
gear oil at the intervals specified in the gener-
al maintenance and lubrication chart.NOTICEECB03600When checking or changing the differen-
tial gear oil, make sure that no foreign ma-
terial enters the differential gear case. If
necessary, clean the differential gear oil
filler bolt and surrounding area.
Checking the differential gear oil level 1. Park the vehicle on a level surface.
2. Remove the differential gear oil filler bolt
and its gasket, and then check the oil lev-
el. It should be up to the brim of the filler
hole.
3. If the level is low, add sufficient oil of the recommended type to raise it to the
specified level.
Tightening torque: Final gear oil filler bolt:23 N·m (2.3 kgf·m, 17 lb·ft)
Recommended oil: SAE 80 API GL-4 Hypoid gear oil
Oil quantity: 0.18 L (0.19 US qt, 0.16 Imp.qt)

4. Check the gasket for damage, and re-place it if necessary.
5. Install the differential gear oil filler bolt and its gasket, and then tighten the bolt
to the specified torque.
Changing the differential gear oil 1. Park the vehicle on a level surface.
2. Place an oil pan under the differential gear case to collect the used oil.
3. Remove the differential gear oil filler bolt, the differential gear oil drain bolt and their
gasket to drain the oil. 4. Install the differential gear oil drain bolt
and its new gasket, and then tighten the
bolt to the specified torque.
5. Refill the differential gear case with the recommended oil.Tightening torque:Differential gear oil filler bolt:23 N·m (2.3 kgf·m, 17 lb·ft)

TIPGL-4 is a quality and additive rating; GL-5
rated hypoid gear oils may also be used.
 If desired, an SAE 80W-90 hypoid gear oil
may be used instead. 6. Check the oil filler bolt gasket for dam-
age, and replace it if necessary.
7. Install the differential gear oil filler bolt and its gasket, and then tighten the bolt
to the specified torque.
8. Check for oil leakage. If oil leakage is found, check for the cause.
EBU35111CoolantThe coolant level should be checked regular-
ly. In addition, the coolant must be changed
at the intervals specified in the periodic main-
tenance chart.TIPIf genuine Yamaha coolant is not available,
use an ethylene glycol antifreeze containing
corrosion inhibitors for aluminum engines and
mix with distilled water at a 1:1 ratio.
Tightening torque:Differential gear oil filler bolt:23 N·m (2.3 kgf·m, 17 lb·ft)
Recommended coolant:YAMALUBE coolant
