Caution
Loose items stored in the cargo
area may damage the CNG fuel
tank and fuel system
components. Secure all items in
the cargo area to avoid shifting
and any damage to the CNG fuel
tank and CNG fuel tank
components.
Starting and
Operating
Starting the Engine
Starting the engine in a CNG
vehicle is similar to starting a
gasoline engine. See “Starting the
Engine” in the owner manual.
Fuel Selection
A switch allows the selection of fuel.
See Fuel 08. The vehicle typically
defaults to the fuel used on the last
key cycle.
If a tank refill has occurred after an
automatic low fuel level transition
from one fuel to another, CNG to
gasoline for example, the vehicle
recognizes the refill and if conditions
are met, will start on the fuel last
selected on the switch.
To protect engine and gasoline fuel
system components, an automatic
switch to gasoline may occur at any
time. The vehicle will transition back
to CNG automatically once the
gasoline system has run for a pre–
set time.

Cold Weather Starting
If the outside temperature is below
2 °C (35 °F), the engine may start on
gasoline when CNG is selected.
After starting on gasoline, the
vehicle will automatically transition
to CNG operation after a set amount
of warm-up time.
Using the engine heater,
if equipped, may make it easier to
start. See“Engine Heater” in the
owner manual.
. Turn off all electrical
accessories.
. Do not hold the ignition switch in
START for more than
15 seconds.
Caution
If you add electrical parts or
accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
See “Add-On Electrical
Equipment” in the owner manual.

Fuel
If a fuel leak is suspected, see Fuel
System Leak 014.
. If the vehicle runs out of CNG or
gasoline, it will automatically
switch to the other fuel system,
if there is fuel.
. If it takes unusually long to fill
the CNG cylinder, the fuel fill
receptacle may be clogged.
Contact your dealer for
inspection and/or replacement.
See “Fuel Filling Problems” in
Filling the Tank (CNG) 09.
This vehicle is designed to operate
on gasoline or CNG and has a
gasoline tank and a CNG fuel
storage system. See “Fuel”in the
owner manual for gasoline
information.

of CNG (for motor vehicles) in the
state of California should be in
compliance with Title 13 California

2292.5. The remaining regions of
North America do not employ
regulated CNG fuel quality
