by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.

vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on a level surface. Make sure the jack arm is
fully seated in the jack take-up bracket.
Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.
