Warning!G
The jack is designed exclusively for jacking 
up the vehicle at the jack tubes built into 
both sides of the vehicle. To help avoid per-
sonal injury, use the jack only to lift the ve-
hicle 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, es-
pecially on hills. Always try to use the jack 
on a hard level surface. Be sure that the jack
arm is fully inserted in the jack tube. Always 
lower the vehicle onto sufficient capacity 
jackstands before working under the vehi-
cle.
