cautions to ensure your drivin g enjoyment and to help prevent t he clo-
sure of areas to off-road vehicles.
● Drive your vehicle only in areas where off-road vehicles are pe rmit-
ted to travel.

private property.

WARNING
■ Off-road vehicle precautions
Always observe the following precautions to minimize the risk o f death, seri-
ous injury or damage to your vehicle:
● In a rollover crash, an unbelted person is significantly more l ikely to die
than a person wearing a seat belt. Therefore, the driver and al l passengers
should always fasten their seat belts.
● Avoid sharp turns or abrupt maneuvers, if at all possible.
Failure to operate this vehicle correctly may result in loss of control or
vehicle rollover causing death or serious injury.
● Avoid loading any items on the roof that will raise the vehicle ’s center of
gravity.
● Always slow down in gusty crosswinds. Because of its profile and higher
center of gravity, your vehicle is more sensitive to side winds than an ordi-
nary passenger car. Slowing down will allow you to have better control.
● When driving off-road or in rugged terrain, do not drive at excessive
speeds, jump, make sharp turns, strike objects, etc. This may c ause loss
of control or vehicle rollover causing death or serious injury. You are also
risking expensive damage to your vehicle’s suspension and chass is.
● Do not drive horizontally across steep slopes. Driving straight up or
straight down is preferred. Your vehicle (or any similar off-ro ad vehicle)
can tip over sideways much more easily than forward or backward .
