Best Method for Stopping CNG Flow
and Turning Off the Engine
Turn off the ignition switch, and remove
the key.
Turning off the ignition switch automatically
shuts off the flow of CNG from the fuel
tank. It also turns off power to the airbags
and the seat belt tensioners within 3
minutes.
To use this method, turn the ignition switch
to the LOCK (0) position, and remove the
key. (Removing the key prevents the vehicle
from being inadvertently restarted.)
Second-Best Method for Stopping
CNG Flow and Turning Off the
Engine
Remove the main fuse, and disconnect
or cut the battery negative cable.
This method should be used if the ignition
switch is in the ON (II) position, and you
cannot reach the key, but you can reach
under the hood.
Removing the main fuse shuts off the flow
of CNG from the fuel tank and turns off the
engine. Disconnecting the battery negative
cable cuts power to the airbags and the seat
belt tensioners within 3 minutes. It also
prevents the engine from being restarted.
