Braking
When slowing down or stopping, take your
foot off the accelerator pedal and press the
brake pedal smoothly. Abrupt or improper
use of the brakes can cause the tires to lose
traction, reducing control of the vehicle and
increasing the possibility of an accident.
Braking ability is affected by type of terrain. In
most cases, gradual application of the brakes
is more effective than abrupt braking, partic-
ularly on loose surfaces, such as gravel. Al-
ways allow for greater braking distance on
rough, loose, or slippery surfaces.
Engine compression braking will also help
slow the vehicle down. With the transmission
still in gear, take your foot off the accelerator
and allow the drivetrain and engine to absorb
vehicle speed. Downshift as necessary. Ap-
plication of the brakes provides additional
stopping power. Leaving the vehicle
Do not get out of the vehicle while the engine
is running. Take the key with when you leave
the vehicle. There is a serious risk of injury or
death because:

Children or other unauthorized persons
may attempt to operate the vehicle.
 Objects tossed into the vehicle may strike
the shift lever and accidently engage the
transmission.
 The parking brake may not keep the vehicle
from moving.
Parking on a flat area
Even when parking on a seemingly flat area, it
is good practice to leave the transmission in
gear to prevent the vehicle from rolling.
Therefore, shift into first or reverse gear, stop
the engine and always apply the parking
brake.UBAS7AE0.book Page 15 Wednesday, June 19, 2019 11:51 AM

Vehicle loading can affect handling as well as
the recommended tire pressure. (See pages
7-12, 6-9.)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 –even on flat, open areas. These rollovers can
result in crushed limbs and other serious inju-
ries or death to drivers or passengers.
When operating the vehicle in areas which re-
quire the use of a safety flag, mount the safety
flag pole on the flag pole bracket. See page
5-32.
Hills
Choose carefully which hills you attempt to
climb or descend. Avoid hills with slippery
surfaces or those where you will not be able
to see far enough ahead of you. Use commonUBAS7AE0.book Page 17 Wednesday, June 19, 2019 11:51 AM

were designed to match the performance ca-
pabilities and to provide the best combination
of handling, braking, and comfort. It is best to
replace all four tires at the same time. If that is
not possible, you must replace the tires in
pairs (front or rear) with tires of the same size
and type as the originals. Never replace just
one tire.
