When wheel spin occurs as the vehicle is moving, the

driver may notice a slight shaking or shuddering of

the vehicle. This should be stopped as soon as possible

to prevent damage to vehicle components. This is the

indication that a loss of traction is occuring on this

terrain. The operator should:

1. Reduce throttle, brake wheels.

2. Assess the terrain properly and adjust vehicle

speed and gear ranges accordingly: 4HI position

for higher speeds and 4LO LOCK for more torque

and lower speeds. Transmission FIRST (1) gear

is generally recommended.

3. Apply slight pressure to the brake when the shaking

or shuddering sensation is felt, keeping the vehicle

moving in a controlled manner.

4. Be prepared to modulate the brake and throttle

through the adverse terrain.

Getting Familiar with Off-Road Driving

It is a good idea to practice in an area that is safe

and close to home before you go into the wilderness.

Off-road driving does require some new and different

skills. Here is what we mean.

Tune your senses to different kinds of signals. Your

eyes, for example, need to constantly sweep the terrain

for unexpected obstacles. Your ears need to listen

for unusual tire or engine sounds. With your arms,

hands, feet and body, you will need to respond

to vibrations and vehicle bounce.

Controlling your vehicle is the key to successful off-road

driving. One of the best ways to control your vehicle

is to control your speed. Here are some things to keep

in mind. At higher speeds:

•

you approach things faster and you have less time

to scan the terrain for obstacles.

•

you have less time to react.

•

you have more vehicle bounce when you drive over

obstacles.

•

you will need more distance for braking, especially

since you are on an unpaved surface.

{

CAUTION:

When you are driving off-road, bouncing and

quick changes in direction can easily throw

you out of position. This could cause you to

lose control and crash. So, whether you’re

driving on or off the road, you and your

passengers should wear safety belts.
