Introduction
Wa r n i n g !
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 were 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, 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.
