5. Position the jack lift head at the jack location
nearest the flat tire. The front location is about
8 inches (20 cm) behind the front wheel opening.
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.
