up the vehicle at the jack take-up brackets 
built into 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 under the lifted vehicle. Always 
firmly set parking 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, 
especially on hills. Always try to use the jack 
on level surface. Make sure the jack arm is
