EMERGENCY PROCEDURES
Be sure to read and understand all information found in theRoadside
emergencychapter of your Owner’s Guide and this supplement.
Do not modify the gaseous fuel injection system configuration or
components. Do not replace the gaseous fuel injection system
components with parts not designed for use with your Bi-fuel vehicle.
Components designed for use in your CNG or LPG Bi-fuel vehicle
consist of special materials and are calibrated especially for your
vehicle. Failure to use the correct components may cause damage to
the engine and fuel system or possible personal injury.
Service to gaseous fuel injection system components must be
conducted only at qualified dealerships by qualified service
technicians. Failure to do so may cause damage to the engine and fuel
system components or possible personal injury.
Any modification to your Gaseous Fuel Injection System voids
the Ford New Vehicle Limited Warranty.
If a CNG fuel leak is suspected or detected, switch operation to
the unleaded gasoline mode and have the complete gaseous fuel
injection system tested by a qualified service technician
immediately.
If the vehicle is involved in an accident or fire that damages any
portion of the gaseous fuel injection system, the damaged
components MUST be replaced and the complete system tested by
a qualified service technician before the vehicle is operated
again.
The fuel selector switch only operates when the vehicle is at a
stop with the ignition in the OFF position. If the fuel selector
switch is moved while the vehicle is running, the gaseous fuel
injection system will NOT automatically change fuel modes and
no damage to the vehicle will occur.
If the engine cranks but does not start after a collision. the fuel
pump shut-off switch may have been activated. Refer to the
Roadside emergencies section of the Owner Guide for
instructions on how to reset the switch.
