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.
 To protect the drivetrain from damage, maximum vehicle speed is limited to approximately 65
km/h (40 mi/h) when in “DIFF. LOCK” mode. UB5J7CE0.book Page 8 Thursday, November 26, 2020 1:37 PM

Practice for new Yamaha YXZ1000E users
Become familiar with the performance char-
acteristics of the vehicle in a large, flat area
that is free of obstacles and other vehicles.
Practice controlling the accelerator pedal,
clutch, brakes, steering, and shift lever. Drive
at slow speeds with gradual acceleration and
smooth turns. Practice applying the accelera-
tor pedal smoothly. Practice slowing down
before turning. Practice maintaining a steady
amount of throttle (accelerator pedal position)
through the turn. Avoid higher speeds until
you are thoroughly familiar with the operation
and handling of the vehicle. Remember, driv-
ing aggressively or making abrupt maneuvers
even on flat, open areas can cause side roll-
overs.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.

Parking on a slope
The parking brake is located on the rear drive
shaft. When the drivetrain is in “2WD” mode,
only the rear wheels will be locked. Therefore,
switch the drive mode to “DIFF. LOCK” be-
fore stopping the engine to lock all four
wheels when parking. In addition to the park-
ing brake, leave the transmission in gear to
help prevent the vehicle from rolling.
If you park on a hill that is too steep, the vehi-
cle may roll out of control. Never park on hills
that are so steep you cannot walk up them
easily. If you must park on an incline, follow
these instructions:1. First, bring the vehicle to a stop and con- tinue to apply the brake pedal.
2. Switch the drive mode to “DIFF. LOCK”
and shift into first gear when parking up-
hill, or reverse gear when parking down-
hill.
TIPYou may need to turn the steering wheel left
and right or release the clutch slightly to help
the differential lock into place. 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 1065 kg (2348 lb).

4. Install the drain bolt and its new gasket,and then tighten the bolt to the specified
torque.
5. Refill with the recommended final gear oil up to the brim of the filler hole.
6. Check the oil filler bolt gasket for dam- age, and replace it if necessary.
7. Install the 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.
EBU36065Differential gear oilCheck the oil level and change the differential
gear oil at the intervals specified in the period-
ic maintenance 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 boltand 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.
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.1. Differential gear oil filler bolt
