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 your brakes. If
necessary, apply the brakes several times to
let friction dry out the linings.
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.

EBU33580Cleaning the air filter elementThe air filter element should be cleaned every
20–40 hours. It should be cleaned and lubri-
cated more often if the vehicle is operated in
extremely dusty areas. Each time air filter ele-
ment maintenance is performed, check the air
inlet to the air filter case for obstructions.
Check the air filter element rubber joint to the
throttle body and manifold fittings for an air-
tight seal. Tighten all fittings securely to avoid
the possibility of unfiltered air entering the en-
gine.NOTICEECB02270Never operate the engine with the air filter
element removed. Doing so would allow
unfiltered air to enter, causing rapid en-
gine wear and possible engine damage.
Additionally, the fuel injection system
would be affected, resulting in poor engine
performance and possible overheating.
1. Remove the storage compartment locat-ed between the driver seat and the pas-
senger seat as shown.
2. Remove the air filter case cover by un- hooking the holders.1. Storage compartment

EBU33672Cleaning the air filter case/air duct
check hoseThere is a check hose at the bottom of the air
filter case and at the bottom of the air duct.
