Pavement
This vehicle is designed for off-road use only.
Avoid paved surfaces. Turn gradually and go
slowly if you must drive on pavement.
Water
If you must cross shallow, slow-moving water
up to the depth of the vehicle’s floorboard,
choose your path carefully to avoid sharp
drop-offs, large rocks, or slippery surfaces
that could cause the vehicle to overturn. Nev-
er operate through water deeper than 37 cm
(15 in) or fast-flowing water. Choose a path
where both your entrance into and exit point
from the water is a gradual incline. Determine
the water depth and currents before crossing.
Operating this vehicle through deep or fast-
flowing water can lead to loss of control or
overturn. To reduce your risk of drowning or
other injuries, use care when crossing
through water.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.
NOTICEECB02170After 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 and air duct and the V-belt case drain
plug. 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 the muffler or exhaust pipe, or next to other hot
parts. Check under the vehicle after operating
in areas where combustible materials may
have collected. Do not idle or park the vehicle
in long dry grass or other dry ground cover.
Encountering obstacles
If you cannot go around an obstacle, such as
a fallen tree or a ditch, stop the vehicle where
it is safe to do so. Set the parking brake and
get out to inspect the area thoroughly. Look
from both your approach side and exit side. If
you believe you can continue safely, choose
the path that will allow you to get over the ob-
stacle and at as close to a right angle as pos-
sible to minimize vehicle tipping. Go only fast
enough to maintain your momentum but still
give yourself plenty of time to react to chang-
es in conditions.UB3D7AE0.book Page 21 Tuesday, November 7, 2017 9:38 AM

If there is any question about your ability to
maneuver safely over the obstacle, you
should turn around if the ground is flat and
you have the room or back up until you find a
less difficult path.UB3D7AE0.book Page 22 Tuesday, November 7, 2017 9:38 AM

most important points of vehicle inspection,
adjustment, and lubrication are explained on
the following pages.
WARNING
EWB01842Failure to properly maintain the vehicle or
performing maintenance activities incor-

lead to eye injury, burns, fire, or carbon
monoxide poisoning - possibly leading
to death. See page 2-5 for more informa-
tion about carbon monoxide.
WARNING
EWB02691Brake discs, calipers, drums, and linings
can become very hot during use. To avoid
possible burns, let brake components cool
before touching them.
