When wheel spin occurs as the
vehicle is moving, the driver may
notice a slight shaking or shudder-
ing of the vehicle. This indicates
that the vehicle is losing traction
on this terrain. This should be
stopped as soon as possible to
prevent vehicle component
damage.

The driver should do the
following:
1. Reduce speed and apply the
brakes.
2. Assess the terrain properly and
adjust the vehicle speed and
gear ranges accordingly.
- Use Four-Wheel High for
higher speeds or Four-Wheel
Low Lock for more torque
and lower speeds.
- Select the proper transmis-
sion gear; usually first gear
for such obstacles.
3. When you feel the shaking or
shuddering sensation, apply
slight pressure to the brake
and keep the vehicle moving
in a controlled manner.
4. Be prepared to alternate
between the brake and throt-
tle through the adverse ter-
rain.
GETTING FAMILIAR WITH
OFF-ROAD DRIVING
It's a good idea to practice in an
area that's safe and close to home
before you go into the wilderness.
Off-road driving does require
some new and different driving
skills.
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'll
need to respond to vibrations and
vehicle bounce.
