Driving and Operating 7
Filling the Tank
{Warning
CNG is flammable and highly
explosive. You could be killed or
seriously injured if leaking natural
gas is ignited. If you suspect a
leak, do not start the engine or
drive the vehicle. Have the
vehicle immediately towed,
inspected, and repaired by an
authorized GM dealer.
{Warning
When refueling in temperatures
below−20 °C (−4 °F), CNG may
leak from the fuel tank valve
pressure relief port if the fast fill
method is used. You or others
could be injured if leaking CNG is
ignited. Fill the vehicle with the
time fill method or refuel when the
temperature is above −20 °C
(−4 °F).
Before filling the fuel tanks, turn off
the engine.
The fill valve is behind a hinged fuel
door on the driver side.
There is an identifying blue
diamond-shaped CNG label on the
right rear cargo door. Do not remove
this label —it is necessary for
compliance with NFPA-52
regulations and insuring the vehicle.
Driving without this label may violate
the laws or regulations in some
states. Replacement labels can be
ordered from your dealer. Refueling Procedure
There are two methods of refueling:
fast filling or time filling. Fast filling
is normally used in fuel stations for
natural gas vehicles. It takes about
six to eight minutes to fill up the fuel
tanks. Time filling is done with a
vehicle refueling appliance or a
time-fill post provided by the fleet
operator. Refueling time varies,
based on the refueling system used.
Consult with the refueling station
attendant or system provider.
Always observe all safety
recommendations and operating
instructions on the refueling
equipment. When refueling, use a
fuel fill nozzle that complies with
ANSI/CSA-NGV 1-2006 standards.
Nozzles are designed according to
their maximum fill pressure: P30
(blue handle) for 20 684 kPa
(3,000 psig) and P36 (yellow
handle) for 24 800 kPa (3,600 psig).
A fuel nozzle less than 7.6 cm (3 in)
long may be difficult to disengage
after dispensing CNG.

Doing Your Own
Service Work
{Warning
Never try to do your own service
work on the Compressed Natural
Gas (CNG) fuel system. The CNG
fuel system operates under high
pressure. You can be injured and
the vehicle can be damaged if
you try to do your own service
work. Service and repair of this
system should only be performed
by a qualified dealer.
Fuel System Components
{Warning
Tampering with, or improperly
maintaining the high-pressure fuel
system can cause a dangerous
condition in which serious injury(Continued)
Warning (Continued)
or death may result. Never
attempt to modify the fuel system,
and always have the fuel system
repaired and maintained by a
qualified dealer.
CNG fuel system components
include fuel tanks located in the
cargo area and under the vehicle,
an integrated fuel pressure
regulator, in-tank fuel shutoff valves,
high pressure fuel lines,
electronically controlled multipoint
fuel injectors, and other equipment.
Fuel system components comply
with appropriate safety standards.
These components have been
designed and approved for use in a
CNG vehicle. Never modify or
replace any original CNG
components or parts with those
specified for a gasoline-powered
vehicle. Improper parts or
components can damage the
vehicle fuel system and affect the
vehicle safety and performance. Do not modify, tamper with,
or perforate the cargo area tank
shield. Damage to the fuel system
can result.
There is an identifying blue
diamond-shaped CNG label on the
rear of the vehicle. Do not remove
this label. This label is necessary for
compliance with NFPA-52 or CSA
B109 regulations. Driving without
this label may violate the laws or
regulations in some jurisdictions.
Replacement labels can be ordered
from your dealer.
