WARNING
This Sport Utility Vehicle is designed for both
on-road and

off-road use. It can go places and
perform tasks for which conventional 2-wheel
drive passenger cars are not intended. This
vehicle will handle and maneuver differently
from conventional passenger cars in driving
conditions which may occur on streets,
highways and off-road use.
This vehicle has a higher ground clearance
and a higher center of gravity than many
passenger cars. As with other vehicles of this
type, if you make sharp turns at excessive
speeds or abrupt maneuvers, the vehicle may
roll over or may go out of control and crash.
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
Failure to operate this vehicle safely may
result in an accident, rollover of the vehicle,
and severe or fatal injury.
Before you start to drive this vehicle, read the
Operator's Manual. Take time to become
familiar with the driving characteristics of this
vehicle. Be sure you are familiar with all
vehicle controls. Learn how your vehicle
handles on different road surfaces. Do not
attempt sharp turns at excessive speeds or
abrupt maneuvers or other unsafe driving
actions that can cause loss of vehicle control.
When driving off-road or working the vehicle
hard, do not overload it. And, always wear
your seat belts at all times. In a rollover crash,
an unbelted person is significantly more likely
to die than a person wearing a seat belt. Operating safety
