Storing a Flat or Spare Tire and
Tools
{CAUTION:
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.
{CAUTION:
The underbody-mounted spare tire needs to be
stored with the valve stem pointing up. If the
spare tire is stored with the valve stem pointing
downward, its secondary latch will not work
properly and the spare tire could loosen and
suddenly fall from your vehicle.
CAUTION: (Continued)
CAUTION: (Continued)
If this happened when your vehicle was being
driven, the tire might contact a person or
another vehicle, causing injury and, of course,
damage to itself as well. Be sure the
underbody-mounted spare tire is stored with
its valve stem pointing up.
Notice:An aluminum wheel with a at tire should
always be stored under the vehicle with the hoist.
However, storing it that way for an extended period
could damage the wheel. To avoid this, always stow
the wheel properly with the valve stem pointing up
and have the wheel repaired as soon as possible.
Follow this diagram to store the underbody-mounted at
or spare tire.
