fill station as soon as it is full,
unless an auto shutoff feature
is used.
{Warning
If CNG tanks are filled to a higher
pressure than recommended and
then exposed to a much higher
ambient temperature
environment, expansion of the
gas caused by the temperature
change may cause pressure relief
devices on the vehicle CNG
tank(s) to release gas, as
designed. If an ignition source is
present, this could create a risk of
fire or explosion. If there is any
possibility that the tank has been
over pressurized, take steps to
relieve the excess pressure, such
as by driving or running the
vehicle in an outdoor open area
to remove some fuel.Make sure that your CNG vehicle is
properly maintained and repaired to
avoid elevated temperatures
surrounding the tank, since elevated
temperatures in the area of the tank
could also raise the CNG pressure
in the tank.

To avoid the risk of fire or explosion
if an ignition source were present,
do not fill above the pressure level
that corresponds to the lowest
ambient temperature expected
during fueling.

12 Driving and Operating
Depending on CNG fill station
equipment/performance, CNG fill
volume will vary. This will affect
overall vehicle range.Put the vehicle into P (Park) and
turn off the engine prior to refueling.
Remove the dust cap from the
receptacle, clean off any dirt or
debris on the receptacle, and followthe refueling instructions on the
pump or provided by the station
operator.
Refueling will stop automatically
when the tank is full. Wait for the
high pressure fuel to be purged from
the hose before disconnecting. See
the station operator for information
on how the line is purged. To
disconnect the vehicle from the
refueling station, remove the nozzle
from the fill receptacle.
A momentary release of CNG will
occur when the nozzle is released.
This is normal.
Put the fill valve dust cap on
securely and close the fuel
filler door.
If fuel or vapor is heard or seen
leaking from the nozzle-fill
receptacle connection, stop
refueling immediately. Dirt or other
debris may be preventing a positive
connection. Turn off the refueling
dispenser, disconnect the nozzle,
and inspect the fill receptacle for a
missing, damaged, dirty, or worn
O-ring. Reconnect the refueling
