Fuel Gauge
The vehicle has a fuel gauge that
displays either gasoline or CNG fuel
level.
Metric
English
With the ignition on, the gasoline/
CNG fuel gauge indicates remaining
fuel in the tank for the fuel that is
being used. See “Fuel Selector
Switch” underFuel08.
To check the level of the fuel not
being used, see Driver Information
Center (DIC) 05.
For CNG, the fuel gauge has been
calibrated to display full at
approximately 24 800 kPa
(3,600 psig) and empty at
approximately 2 758 kPa (400 psig).

4 Instruments and Controls
CNG fuel gauge readings are
affected by changes in fuel
temperature and fuel pressure.
See“Fuel Gauge” in the owner
manual.
Malfunction Indicator
Lamp (Check Engine
Light)
The malfunction indicator lamp is in
the instrument cluster.
This vehicle has been specifically
designed to illuminate this indicator
when emissions exceed acceptable
levels while operating on either
gasoline or CNG fuel.
The malfunction indicator lamp
comes on to indicate that there is a
problem and service is required.
Malfunctions often will be indicated
by the system before any problem is apparent. This system is also
designed to assist the service
technician in correctly diagnosing
any malfunction.
Caution
If the vehicle is continually driven
with this light on, the emission
controls might not work as well,
the vehicle fuel economy might
not be as good, and the engine
might not run as smoothly. This
could lead to costly repairs that
might not be covered by the
vehicle warranty.
This light should come on as a
check to show you it is working
when the ignition is on and the
engine is not running.
This light comes on during a
malfunction in one of two ways:
Light Flashing
A misfire condition has been
detected. A misfire increases
vehicle emissions and could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
To prevent more serious damage to
the vehicle:
.
Reduce vehicle speed.
. Avoid hard accelerations.
. Avoid steep uphill grades.
If the light continues to flash, find a
safe place to stop and park the
vehicle. Turn the vehicle off, wait at
least 10 seconds, and restart the
engine. If the light is still flashing,
follow the previous steps and see
your dealer for service as soon as
possible.
Light On Steady
An emission control system
malfunction has been detected on
the vehicle. Diagnosis and service
might be required.
See the owner manual for more
information.

10 Driving and Operating
Warning (Continued)
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.
Before filling either fuel tank, turn off
the engine.
The gasoline tank is filled through
the standard fill pipe. See “Filling
the Tank” under“Fuel” in the owner
manual.
The CNG fill receptacle is behind
the fuel door on the passenger side
above the gasoline cap.
Refueling Procedure
There are two methods of refueling:
fast fill or time fill. Fast fill is
normally used in fuel stations for
natural gas vehicles. It takes about
two to five minutes to fill up the fuel
tank. Time fill is done with a
refueling appliance, including
residential appliances, or a time-fill
post provided by the fleet operator.
Refueling time varies depending
upon 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. If a 24 800 kPa
(3,600 psig) nozzle is not available,
a 20 684 kPa (3,000 psig) nozzle
may be connected to the vehicle.
A fuel nozzle less than 7.6 cm (3 in)
long may be difficult to disengage
after dispensing CNG. During fueling, CNG needs to be
delivered to the vehicle at the
appropriate pressure in relationship
to the ambient temperature. This
can be done automatically by a
temperature compensation system
on the CNG fuel dispenser or
manually by stopping the CNG fill at
a recommended pressure related to
the ambient temperature
compensation chart. GM
recommends that customers use
CNG fueling stations that have a
temperature compensation system
whenever possible. Check with the
fuel station. If one is not available,
see the temperature compensation
chart that follows in this section to
choose the appropriate fill pressure
for the ambient temperature. In
addition, fill only to the pressure
level for the lowest ambient
temperature anticipated during
fueling.
Leaving a vehicle connected to a
time fill station can cause the tank
to be filled to a higher pressure than
recommended, especially when
outside temperatures fluctuate.
Disconnect the vehicle from the time
