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. If you feel the vehicle begin to slide sideways
or the back wheels slide during a turn, steer
into the direction of the slide if possible, to re-
gain directional 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 passengers.
Never hold onto the cage/frame. The passen-
gers 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 theUB427AE0.book Page 20 Monday, May 18, 2015 9:17 AM

Installation1. Clean the surface of the spark plug gas-
ket and its mating surface, and then wipe
off any grime from the spark plug
threads.
2. Install the spark plug and tighten it to the specified torque. If a torque wrench is not
available when you are installing the
spark plug, a good estimate of the cor-
rect torque is one-quarter to one-half turn
past finger tight. Have the spark plug
tightened to the specified torque as soon
as possible.
3. Install the spark plug cap.
4. Lower the cargo bed.
EBU34810Cleaning 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.
Spark plug gap: 0.8–0.9 mm (0.031–0.035 in)
Tightening torque: Spark plug:13 Nm (1.3 m·kgf, 9.4 ft·lbf)
