EBU31930ParkingWhen parking, stop the engine and shift the
drive select lever into the neutral position. Ap-
ply the parking brake to help prevent the ve-
hicle from rolling. See page 7-17 for more
information on parking and parking on a
slope.EBU31940LoadingTake extra precautions when driving with a
load or trailer. Follow these instructions and
always use common sense and good judg-
ment when carrying cargo or towing a trailer.
Prepare your load or trailer
WARNING
EWB03310Improper loading or towing can increase
the risk of loss of control, an overturn, or
other accident: 
Do not exceed the Maximum Loading
Limits for the vehicle (see “MAXIMUM
LOADING LIMIT” in this section and ve-
hicle labeling).
 Keep weight in the cargo bed centered
side to side, and as low and as far for-
ward as possible. Top-heavy loads in-
crease the risk of overturn. Be sure
cargo is secured – a loose load could
change handling unexpectedly or strike
occupants.
 Do not exceed the maximum tongue
weight.
 Make sure the load does not interfere
with your control or ability to see where
you are going.
 Tie down cargo in the trailer securely.
Make sure cargo in the trailer cannot
move around. A shifting load can cause
an accident.
Use the hooks equipped on the cargo bed to
tie down loads.

of injury in accidents. The protective structure
will not protect occupants in all rollovers or
accidents.
Body parts outside of vehicle can be struck
by passing objects or crushed during vehicle
rollover. Do not put your hands or feet outside
of the vehicle for any reason. Do not hold onto
the door, cage/frame or shoulder bolster.
Wear your seat belt and helmet.
If you think or feel that the vehicle may tip or
roll, do not put your hands or feet outside the
vehicle for any reason. You will not be able to
stop the vehicle from tipping over using your
body. Any part of your body (arms, legs, or
head) outside of the vehicle can be crushed
by the vehicle cage/frame.
Seat belts
Seat belts should be worn by the driver and
passengers. The driver must be sure that the
passengers are belted before driving. 
Be sure that each occupant’s seat belt
latch plate is inserted into the appropriate
buckle.
 Be sure the seat belt is not twisted, is close-
fitting across the hips and chest, and is
latched securely.
 Do not wear the seat belt across the abdo-
men or stomach.
 Do not put the seat belt behind the back.
Failure to use seat belts properly may lead to
an increased likelihood and severity of injury.
An unbelted occupant may strike the interior
of the vehicle, the protective structure, or oth-
er objects in an accident or during operation.
You may also fall completely out or be partial-
ly ejected from the vehicle, which may lead to
being crushed between the ground and the
vehicle. Wearing the seat belt helps you re-
main in the vehicle – the doors and passenger
handhold are not a substitute for using a seat
belt.UB857AE0.book Page 5 Monday, August 24, 2015 8:59 AM

reason in a rollover. The doors may also re-
duce intrusion of objects into the occupant
area. Make sure the door is securely latched
before operation. Do not place your arm or
hand on the door during operation. Your hand
or arm may be struck by objects or crushed
against outside objects or the ground during

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.
EBU34821Cleaning 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 elem ent 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, re sulting 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)

gerprints on the headlight bulb using a
cloth moistened with alcohol or thin-
ner.
