Storing a Fla' or Spare 'ire :
d Tools
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.
The underbody-mounted spaL, tire needs to
be stored with the valve stem pointing down.
If the spare tire is stored with the valve stem
pointing upwards, its secondary latch won't
work properly and the spare tire could loosen
and suddenly fall from your vehicle. 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 down.
