Perform the Pre-Operation Checks on pages 5-1–
5-35. Set the parking brake, shift to neutral, and
follow the instructions on page 6-3 to start the en-
gine. Once it has warmed up and you have turned
the choke off, you are ready to begin driving your
vehicle. With the engine idling, shift the drive se-
lect lever into low or high. Then release the parking
brake. Press the accelerator pedal slowly and
smoothly. The centrifugal clutch will engage and
you will start to accelerate. Avoid higher speeds
until you are thoroughly familiar with the operation
of your vehicle.
When slowing down or stopping, take your foot off
the accelerator pedal and smoothly press the
brake pedal. Improper use of the brakes can
cause the tires to lose traction, reducing control
and increasing the possibility of an accident.

If you start to lose traction or momentum when
climbing, and you decide you will be unable to con-
tinue, use the brakes to come to a stop. Do not at-
tempt to turn the vehicle around. With your foot on
the brake, look behind you and plan your descent.
Shift the drive select lever in reverse so you can
use the engine brake if necessary to slow your de-
scent. Release the brake and begin to coast down
the hill. Use engine braking as much as possible,
gently applying the brakes when necessary.
GOING DOWNHILL
Check the terrain carefully before going down a
hill. When possible, choose a path that lets you
drive your vehicle straight downhill. Avoid sharp
angles that could allow the vehicle to pitch or roll
over. Carefully choose your path and drive no fast-
er than you will be able to react to obstacles that
may appear.

WARNING
Going down a hill improperly could cause loss
of control or cause the vehicle to overturn.

Always check the terrain carefully before
you start down any hill.


Never go down a hill at high speed.


Avoid going down a hill at an angle that
would cause the vehicle to lean sharply to
one side. Go straight down the hill where
possible.
Before starting down hill, make sure the vehicle is
in low-range 4WD. On most slopes, this will let you
use engine braking to help you go downhill slowly.
Go as slowly as possible. If you are starting to go
too fast, apply the brakes gently. Avoid sudden ap-
plication of the brakes, which could cause the ve-
hicle to start sliding.
If you are sliding or skidding, try to steer in the di-
rection the vehicle is sliding to help you regain con-
trol.

changed and the oil filter cartridge replaced at the
intervals specified in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the vehicle on a level surface.
2. Remove the console. (See page 8-21 for
console removal and installation proce-
dures.)
3. Start the engine, warm it up for several min-
utes, and then turn it off.
4. Wait a few minutes until the oil settles.

6. Insert the dipstick in the oil filler hole (without
screwing it in), and then remove it again to
check the oil level.NOTE:_ The engine oil should be between the minimum
and maximum level marks. _7. If the engine oil is at or below the minimum
level mark, add sufficient oil of the recom-
mended type to raise it to the correct level.
8. Insert the dipstick into the oil filler hole, and
then tighten the oil filler cap.
9. Install the console.

The coolant level should be checked before each
ride.
Checking the coolant level
1. Place the vehicle on a level surface.
2. Open the hood. (See pages 8-17–8-19 for
hood opening and closing procedures.)
3. Check the coolant level in the coolant reser-
voir when the engine is cold as the coolant
level varies with engine temperature.NOTE:_ The coolant should be between the minimum and
maximum level marks. _4. If the coolant is at or below the minimum level
mark, remove the reservoir cap, add coolant
to the maximum level mark, install the reser-
voir cap, and then close the hood.
Coolant reservoir capacity
(up to the maximum level mark):
