Onpavement and offroad driving tips
This vehicle belongs to the utility vehicle class. Utility vehicles
have a significantly higher rollover rate than other types of
vehicles. This vehicle will handle and maneuver differently
from an ordinary passenger car because it is designed for
off−road use also. In addition, this vehicle has a higher ground
clearance and center of gravity than that of an ordinary
passenger car. This vehicle design feature causes this type of
vehicle to be more likely to rollover. Failure to operate this
vehicle correctly may result in loss of control, accidents or
vehicle rollover causing death or serious injury. Be sure to read
“Off −road vehicle precautions” on page 339 and “Off −road
driving precautions” on page 343.
