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.

Attach the ratchet, with the
UP mark facing you,

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
