Buick Regal Owner's Manual page 329

Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the
appropriate safety equipment and
training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could
be badly injured or killed if the
vehicle slips off the jack. If a jack
is provided with the vehicle, only
use it for changing a flat tire.
7. Attach the jack lift assist tool to
the jack by fitting both ends of
the jack and tool over one
another.
8. Place the jack under the vehicle.
9. Position the jack lift head at the
jack location nearest the flat tire.
The location is indicated by a
mark near the bottom edge of
the lower molding. The jack
must not be used in any other
position.
10. Raise the vehicle by turning the
jack handle clockwise. Raise
the vehicle far enough off the
ground so there is enough
room for the road tire to clear
the ground.
