Abrupt maneuvers or aggressive driving, even on flat, open areas, can cause loss of control,
including rollovers. The Wolverine has higher ground clearance and other features to handle
rugged terrain, and, as a result, can overturn in situations where some other vehicles may not.
 Avoid rollovers:
• Use care when turning:
• Turning the steering wheel too far or too fast can result in a rollover.
• Avoid sideways sliding, skidding, or fishtail ing (rear-wheel sliding), and never do donuts.
• Slow down before entering a turn and avoid hard braking in a turn.
• When making tight turns from a stop or at sl ow speeds, avoid sudden or hard acceleration.
• Drive straight up and down inclines, not across them. If crossing a hill is unavoidable, drive
slowly and turn downhill immediately if you feel the vehicle may tip.
• Avoid paved surfaces. Turn gradually and go slowly if you must drive on pavement. This vehicle is designed for off-road use only.UB3D7AE0.book Page 4 Tuesday, November 7, 2017 9:38 AM

If you think or feel that the vehicle may tip or roll, keep your body completely inside the protec-
tive structure of the vehicle:
• Brace yourself by pressing your feet firmly on the floorboard and keep a firm grip on the
steering wheel or passenger handhold.
• Do not put your hands or feet outside of the vehicle for any reason. Your arm or leg could be
crushed.
• Do not try to stop a vehicle tipover using your arm or leg.
 Do not operate this vehicle on any public street , road, or highway, even if dirt or gravel.
 Do not operate the vehicle in fast-flowing water or water deeper than 37 cm (15 in). If you must
cross shallow, slow-moving water, choose your path carefully to avoid sharp drop-offs, large
rocks, or slippery surfaces. Operating this vehi cle through deep or fast-flowing water can lead
to loss of control or overturn. To reduce your risk of drowning or other injuries, use care when
crossing through water.
 When loaded with cargo or towing a trailer:
• Reduce speed, operate in low gear only, and allow more room to stop.
• Avoid hills and rough terrain. Use extreme cautio n when towing or carrying a load on inclines.
• Load trailer properly and use extra care when towing or pulling.
 Do not tow or pull objects from any part of the vehicle other than the trailer hitch bracket or
winch (if installed).
