5. After making sure no one is in the vehicle, raise it high enough
so that the spare tire can be installed.
Allow for the fact that you need more ground clearance when putting
on the spare tire than when removing the flat tire.
To raise the vehicle, insert the jack handle into the jack (it is a loose
fit) and turn it clockwise. As the jack touches the vehicle and begins
to lift, double–check that it is properly positioned.
CAUTION
Never get under the vehicle when the vehicle is supported by
the jack alone.
