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.
