command or automatically if the driveline is under torque. If driving
conditions allow, releasing the accelerator pedal or turning the steering

PREPARING TO DRIVE
WARNING:
Utility vehicles have a significantly higher rollover
rate than other types of vehicles.
WARNING:
In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt.
Utility vehicles and trucks have larger tires and increased ground
clearance, giving the vehicle a higher center of gravity than a passenger
car.
