Ram Trucks 2015 3500 - CNG Supplement - Manual (Page 9)

• Natural gas contains an odorant additive and persistent
natural gas odor may indicate a leak. If a persistent
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 very high pressure even when
the engine is not running. To avoid risk of personal
injury, any repair to the fuel system should be per-
formed 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 provided 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.
• When a vehicle is involved in an accident which has or
may have caused damage to the natural gas fuel system,
the system must be inspected and pressure tested by
a qualified technician before returning the vehicle to
service.
• Any fuel system component, including the containers,
that has been subjected to fire may not be returned to
service due to reduced pressure capability.
