over. Practice first on gentle slopes before at-
tempting steeper hills. Always check the
terrain carefully before attempting any hill.
To climb a hill, you need traction, momentum,
and steady throttle. For more traction and
control for climbing steeper and/or rougher
slopes, shift into low gear and select “4WD”
or “DIFF LOCK”. Travel fast enough to main-
tain momentum, but not so fast that you can-
not react to changes in the terrain as you
climb.
Slow down when you reach the crest of the
hill if you cannot see clearly what is on the
other side – there could be another person, an
obstacle, or a sharp drop-off.
If you start to lose traction or momentum
when climbing, and decide you will be unable
to continue, use the brakes to stop. Do not at-
tempt to turn the vehicle around. With your
foot on the brake pedal, look behind you and
plan your descent. Shift the transmission into
reverse so you can use engine braking to
slow your descent. Release the brake, andthen begin to coast down the hill. Use engine
braking as much as possible, gently applying
the brakes when necessary.
Downhill
Check the terrain carefully before going
downhill. When possible, choose a path that
lets you drive your vehicle straight downhill.
Choose your path carefully and drive slowly
enough to be able to react to obstacles that
you encounter.
For more traction and control, before going
down steeper and/or rougher slopes, shift
into low gear and select “4WD” or “DIFF
LOCK”. Engine braking will help you go
downhill slowly. Go as slowly as possible. If
you begin to go too fast, apply the brakes
gently. Avoid hard application of the brakes,
which could cause the vehicle to slide.UB5H7AE0.book Page 19 Wednesday, July 4, 2018 1:37 PM

Wet brakes may have reduced effectiveness.
After leaving the water, test the brakes. If nec-
essary, apply the brakes several times to let
friction dry them out.NOTICEECB02950After driving your vehicle in water, be sure
to drain the trapped water by removing the
check hoses at the bottom of the air filter
case. Wash the vehicle in fresh water if it
has been operated in salt water or muddy
conditions. Loose terrain/slippery terrain
When driving on slippery terrain, including
wet, muddy, or icy conditions, as well as
loose gravel, be aware that you could begin
skidding or sliding. To avoid loss of control,
slow down and put the vehicle in four-wheel
drive before driving on a slippery surface and
plan your path to avoid making abrupt ma-
neuvers. If you feel the vehicle begin to slide sideways
or fishtail (rear-wheel sliding), steer into the di-
rection of the slide if possible, to regain direc-
tional control. For example, if you feel the
back of the vehicle start
to slide to your right,
steer to the right.
Brush or wooded areas
When operating in areas with brush or trees,
watch carefully on both sides and above the
vehicle for obstacles such as branches that
the vehicle might hit, causing an accident.
Watch for brush that might enter the vehicle
as you pass and strike you or the passenger.
Never hold onto the cage/frame. The passen-
ger should always hold onto the passenger
handhold with both hands.
The muffler and other engine parts become
extremely hot during operation and remain
hot after the engine has stopped. To reduce
the risk of fire during operation or after leaving
the vehicle, do not let brush, grass and other
materials collect under the vehicle, near theUB5H7AE0.book Page 21 Wednesday, July 4, 2018 1:37 PM
