stops moving upward and is held firmly in place,

has released.

counterclockwise. Keep lowering the jack until
the compact spare tire is resting on the folding
wrench.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or flat tire using
the hoist assembly until it has been repaired or replaced.
Removing the Wheel Covers
If the wheel has a center cap, use the handle of the
folding wrench to pry it off. Then, with the other end of
the folding wrench, loosen the nuts.
5. Grasp the compact spare tire with both hands and
pull it out from under the vehicle.
6. Reach under the vehicle and remove the folding
wrench and jack.
If your vehicle has the plastic "bolt-on" wheel covers,
loosen the bolts completely using the folding wrench,
and remove the wheel cover.
