the switch again to deactivate the system. The “Sway Bar
Indicator Light” (located in the instrument cluster) will

On-Road Driving Tips
Utility vehicles have higher ground clearance and a nar-
rower track to make them capable of performing in a wide
variety of off-road applications. Specific design character-
istics give them a higher center of gravity than conven-
tional passenger cars.
An advantage of the higher ground clearance is a better
view of the road, allowing you to anticipate problems.
They are not designed for cornering at the same speeds as
conventional passenger cars any more than low-slung
sports cars are designed to perform satisfactorily in off-
road conditions. Avoid sharp turns or abrupt maneuvers.
As with other vehicles of this type, failure to operate this
vehicle correctly may result in loss of control or vehicle
rollover.
