application).
If yourBi-fuelvehicle operates on LPG, under very cold conditions
(below–7°C [20°F]) the gaseous fuel injection system may, as indicated

To avoid damage to the unleaded gasoline fuel injection system of
your Bi-fuel vehicle, operate your vehicle at least every 60 days
using unleaded gasoline. Use a minimum of one full tank of
unleaded fuel every 60 days.
The characteristics of LPG are unique from those of CNG, unleaded
gasoline and diesel fuel. If yourBi-fuelvehicle operates on LPG, the
gaseous fuel injection system may, as indicated by the label on the
dashboard or the sun visor, automatically change to the unleaded
gasoline operating mode under certain conditions in very cold
temperatures (below–7°C [20°F]).
If you expect to operate your LPG Bi-fuel vehicle in very cold
temperatures, be sure to maintain an adequate supply of
unleaded gasoline in the fuel tank.
