7. 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

properly positioned.
CAUTION
Never get under the vehicle when the vehicle is
supported by the jack alone.
