OPERATION
Driving on a Sidehill (Sidehilling)
Driving on a sidehill is not recommended. Improper procedure could
cause loss of control or rollover. Avoid crossing the side of any hill
unless absolutely necessary.
If crossing a hill is unavoidable, follow these precautions:
1. Engage all-wheel drive.
2. Drive slowly and use extreme caution.
3. If the vehicle begins to roll over, or if it feels as if it may roll over,
immediately turn downhill.
4. Avoid obstacles and changes in terrain that may lower or raise one
side of the vehicle or cause the vehicle to slide.
5. If the vehicle begins to slide downhill, immediately turn downhill to
stop the slide, or stop the vehicle and maneuver slowly and
carefully until the vehicle can be driven straight downhill.
