Protective structure
The vehicle cage/frame provides a protective
structure that helps limit intrusions by branch-
es or other objects and may reduce your risk
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
passenger. The driver must be sure that the
passenger is belted before driving.

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.UB3D7AE0.book Page 5 Tuesday, November 7, 2017 9:38 AM

3. Push the latch plate into the buckle until itclicks. Pull up on the latch plate to make
sure it is secure.
4. Put the lap portion of the belt low on your hips. Pull up on the shoulder part so the
belt is snug across your hips. Be sure the
seat belt is not caught on the shoulder
bolster or other object. 5. Position the shoulder belt over your
shoulder and across your chest. The
shoulder belt should fit against your
chest. If it is loose, pull the belt out all the
way and then let it retract.
6. Check if the seat belt shoulder position suits the size of the driver and passenger.
To lower the belt, insert the belt into the
seat belt height adjuster slot as shown.
To raise the belt, remove the belt from the
height adjuster slot.1. Buckle

Doors
The doors are designed to reduce the likeli-
hood that you will stick your leg out to stop
the vehicle from tipping over or for any other
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
a rollover. Passenger handhold
The passenger handhold is provided to grip
during operation to maintain proper position
and balance. Holding onto the handhold
helps to reduce the likelihood that the pas-
senger puts a hand outside the vehicle if the
vehicle begins to tip.
The driver should make sure the passenger is
holding onto the handhold with both hands
before operating the vehicle.

The seats and shoulder bolsters are designed
to help keep you in the vehicle. Do not put
your hand or arm on or outside of the shoul-
der bolster during operation. Your hand or
arm may be struck by objects or crushed
against outside objects or the ground during
a rollover.1. Handhold support

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.
EBU33581Cleaning 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:11 N·m (1.1 kgf·m, 8.1 lb·ft)
