302 WHAT TO DO IN EMERGENCIES WARNING! Raising the vehicle higher than necessary can make the vehicle less stable. It could slip off the jack and hurt someone near it.

Lightly tighten the nuts. To avoid the risk of forcing the vehicle off the jack, do not tighten the nuts fully until the vehicle has been lowered. 8. Lower the vehicle by turning the jack screw counter clockwise, and remove the jack and wheel blocks. 9. Finish tightening the lug nuts. Push down on the wrench while tightening for increased leverage. Alternate Rear Jacking Location 5. Raise the vehicle by turning the jack screw clockwise.
