The jack is designed exclusively for jacking
up the vehicle at the jack tubes built both
sides of the vehicle. To help avoid personal
injury, use the jack only to lift the vehicle
during a wheel change. Never get beneath
the vehicle while it is supported by the jack.
Keep hands and feet away from the area un-
der the lifted vehicle. Always firmly set park-
ing brake and block wheels before raising
vehicle with jack.
Do not disengage parking brake while the
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 level surface. Make sure the jack arm is
fully inserted in the jack tube. Always lower
the vehicle onto sufficient capacity jack-
stands before working under the vehicle.
