frame  behind  the  flat tire.  If the  flat  tire is on  the 
rear,  position  the jack  on the  rear  axle  between  the 
spring  and  the  shock  absorber.

Getting  under a vehicle when  it is jacked  up is 
dangerous. If the  vehicle  slips off the  jack, you 
could be  badly  injured  or  killed. Never  get  under 
a vehicle when it is supported  only by a  jack. 
NOTICE: 
Raising  your  vehicle with the  jack  improperly 
positioned  will damage  the  vehicle or may  allow 
the  vehicle  to 
fall off the  jack.  Be sure  to  fit  the 
jack  lift  head  into  the  proper  location  before 
raising  your  vehicle.

Put  the  tire  on  the  ground  at  the  rear of the  vehicle 
with  the  valve  stem  pointed  down  and 
to the  rear. 
Tilt 
the retainer  downward  and  through  the  wheel 
opening.  Make  sure  that  the  retainer 
is fully  seated 
across  the  underside  of the  wheel. 
Attach  the  ratchet,  with  the 
UP mark  facing  you, 
near  the  hook  at  the  end 
of the  jack  handle.  Insert the 
other  end,  on  an  angle, through 
the hole in  the rear 
bumper  and  into the  hoist  shaft. 
Raise  the  tire  fully  against  the  underside 
of the 
vehicle.  Continue  turning  the  ratchet 
until there  are 
two  “clicks”  or “ratchets.”  The  spare  tire  hoist 
cannot  be  over-tightened. 
Grasp  and  push  against  the  tire to be  sure it  is  stored 
securely  and  does  not  move.
