244 WHAT TO DO IN EMERGENCIES
Rear Jacking Location
5. Raise the vehicle by turning the jack handle clockwise
until the tire clears the ground.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
6. Remove the lug nuts and wheel.
7. Position the spare wheel/tire on the vehicle and install
the lug nuts with the cone-shaped end toward the wheel.
Lightly tighten the nuts until they are equally snug, using
a crisscross pattern. 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 and remove the jack and wheel
blocks.
