Storing a jack, a tire, or other
equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store all these in
the proper place.
Store the spare or flat tire in one of
the ways shown below. Storage
instructions will vary depending on
the bolt that came with the vehicle
and how it attaches to the vehicle.
This vehicle will have a slide in
fastener or a screw in fastener.
1. Turn the wrench
counterclockwise to remove the
fastener.
2. Replace the fastener with the
one provided in the foam.
3. Turn the wrench clockwise to
tighten the fastener.
4. Replace the foam, jack and
tools, and the tire.
5. Turn the retainer nut clockwise
to secure the tire.
6. Place the floor cover on the
wheel.
1. If the flat tire is larger than the
spare tire, use the longer
mounting bolt.
2. Slide the shorter bolt to remove
it from the floor and insert the
longer one.
3. Replace the jack and tools in
their original storage location.
