The rear location is about 4 inches (10 cm) in
front of the rear wheel opening.
6. Raise the jack head until it fits firmly in the
vehicle's frame, where the notch is located,
nearest the flat tire.
7. Put the compact spare tire near the flat tire.
CAUTION:
{
Getting under a vehicle when it is jacked
up is dangerous. If the vehicle slips off
the jack you could be badly injured or
killed. Never get under a vehicle when
it is supported only by a jack.
CAUTION:
{
Raising your vehicle with the jack
improperly positioned can damage the
vehicle and even make the vehicle fall.
To help avoid personal injury and vehicle
damage, be sure to fit the jack lift head
into the proper location before raising the
vehicle.
8. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off
the ground so there is enough room for
the compact spare tire to fit under the vehicle.
