Storing a Flat or Spare Tire
and Tools
WARNING
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.
To store the flat tire:
1. If the flat tire is larger than the
spare tire, use the longer
mounting bolt from the tool bag.
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.
