• Do not attempt to force open or tamper with the fuel
fill receptacle. A sudden release of natural gas may
occur, possibly causing injury.
• Natural gas contains an odorant additive and persis-
tent natural gas odor may indicate a leak. If a persis-
tent natural odor is detected, the cause should be
located and corrected immediately by a qualified
technician.
• Do not park or service your vehicle near any source of
excessive heat or open flame. Never use a paint oven
to cure any paint repairs. The natural gas storage
containers on this vehicle are equipped with pressure
relief devices which vent at 230° F (110° C).
• Do not paint or under coat any natural gas fuel system
components. Unlike gasoline, a compressed natural
gas fuel system is under pressure even when the
engine is not running. To avoid risk of personal injury,
any repair to the fuel system should be performed by
a qualified technician.
• Natural gas vapors at atmospheric pressure are lighter
than air and will rise and disperse in open areas. In
enclosed areas, natural gas vapor may collect and form
a combustible mixture. If the vehicle is routinely
placed in an enclosed area, the area should be pro-
vided with adequate ventilation and/or a natural gas
detection system. For long term storage, the manual
shutoff valve and individual container valves should
be closed.
