ABOUT THIS SUPPLEMENT
This booklet supplements your Owner’s Guide and is part of the owner’s
portfolio. It describes the operation of yourBi-fuelvehicle and how it
differs from a standard gasoline powered vehicle. Therefore it is very
important that you read this guide and thoroughly familiarize yourself
and others operating the vehicle with this information.
Some of the information in this supplement replaces certain instructions
in the Owner’s Guide. Please read this supplement carefully and
completely. Refer to the Owner’s Guide for complete vehicle information.
WARNINGS
Warnings remind you to be especially careful in those areas of the
vehicle where carelessness can cause damage to your vehicle or possible
personal injury to yourself, your passengers or others. Please read all
warnings carefully.

ABOUT THE WARRANTIES
The normal vehicle warranties will apply to yourBi-fuelvehicle. For
further information, refer to your Warranty Information Booklet in the
owner’s portfolio.
Specified maintenance procedures must be followed. Repairs must be
made by trained personnel.
It is important that yourBi-fuelvehicle be properly maintained by
qualified Ford service technicians. If a concern occurs, it is important
that properly trained personnel diagnose and repair the cause. If the
concern relates to the fuel system, proper part replacement is imperative
to keep your vehicle operating correctly.Bi-fuelcomponents and
standard fuel components are not interchangeable. If yourBi-fuel
vehicle is not maintained in accordance with approved service
procedures, damage may occur and your warranty may be invalidated.
GASEOUS FUEL INJECTION
YourBi-fuelvehicle is equipped with two fuel injection systems, an
unleaded gasoline fuel system and a gaseous fuel injection system.
Two types of gaseous fuel injection systems are available:
•Compressed Natural Gas (CNG)
•Liquefied Petroleum Gas (LPG)
Introduction

Labels similar to these are located in
the engine compartment and
contain diagnostic information for
your gaseous fuel injection system.
Compressed natural gas (CNG)
This label is located on the right
rear of your vehicle and identifies
the vehicle as using compressed
natural gas (CNG) as a fuel.
This warning label is located in the
engine compartment to help ensure
safe and proper maintenance of the
CNG fuel system.
Introduction

This label is located in the engine
compartment and on the CNG
tank(s) and lists the inspection and
expiration dates for the CNG fuel
tank(s).
Liquefied petroleum gas (LPG)
This label is located on the right
rear of your vehicle and identifies
the vehicle as using liquefied
petroleum gas (LPG) as a fuel.
This warning label is located on
either the driver’s side sun visor or
on the dashboard to help inform you
of cold weather operating conditions
when using LPG as a fuel.
This warning label is located in the
engine compartment to help ensure
safe and proper maintenance of the
LPG fuel system.
Introduction

The vehicle’s fuel system will NOT automatically change to the
gaseous fuel mode (CNG or LPG , depending upon application), if
the level of the unleaded gasoline runs low.
FUEL GAUGE
The fuel gauge in your CNG or LPGBi-fuelvehicle (depending upon
application) behaves similarly to a standard gasoline fuel gauge. The fuel
gauge will provide a linear reading from Full down to Empty.
•Fuel gauge operation for aLPG Bi-fuelvehicle is based on a float
type sensor measuring the level of the liquid propane in the fuel
tank(s).
•Fuel gauge operation for aCNG Bi-fuelvehicle is based on the
pressure and temperature of the natural gas in the fuel tank(s).
Depending upon the application, a full fuel gauge reading will occur at
a pressure of approximately 20 700 kPa (3 000 psi) or 24 800 kPa (3
600 psi) at a temperature of approximately 21°C (70°F). For more
information on fuel gauge performance during the fast-fill method of
CNG fueling, refer toRefueling your Bi-fuel vehiclein the
Maintenance and carechapter of this supplement.
WARNING LIGHTS
With the engine running, the“Check Engine/Service Engine Soon”
indicator light (depending upon application) will illuminate on the
instrument cluster when the On Board Diagnostics System and/or the
Gaseous Fuel Injection System detects a malfunction in one of the
engine’s emission controls. For more information, refer toWarning light
and chimesin theInstrumentationchapter of your Owner’s Guide and
this supplement.
If a malfunction of the LPG Gaseous
Fuel Injection System is detected
with the engine running in the
gaseous fuel mode, the green
indicator light on the fuel selector
switch will flash on and off.
The warning lights may illuminate or flash on and off (depending upon
application) without a driveability concern being noted. The vehicle will
usually be drivable and will not require towing. Contact a qualified Ford
dealership at the first available opportunity.

JACKING YOUR BI-FUEL VEHICLE
YourBi-fuelvehicle may be lifted with the emergency jack as described
inChanging the tiresin theRoadside emergencieschapter of the
Owner’s Guide.
When lifting yourBi-fuelvehicle, follow these additional steps:
•SHUT OFF the gaseous fuel injection system as outlined inGaseous
fuel injection system shutoffin theMaintenance and carechapter
of this supplement.
•DO NOT use the gaseous fuel injection system components (e.g.
tanks, brackets, valves, covers and fuel lines) as a lifting or contact
point.
•DO NOT allow lifting of vehicle to twist or distort the fuel lines of
your gaseous fuel injection system.
TOWING YOUR BI-FUEL VEHICLE
Refer toWrecker towingin theRoadside emergencieschapter of the
Owner’s Guide for towing procedures, except Econoline with the optional
fuel tank package whichmustbe flat-bed towed.
When towing yourBi-fuelvehicle, follow these additional steps:
•SHUT OFF the gaseous fuel injection system as outlined inGaseous
fuel injection system shutoffin theMaintenance and carechapter
of this supplement.
•DO NOT attach tow bars, tow chains, tow straps or safety chains to
the gaseous fuel injection system components (e.g. tanks, brackets,
valves, covers and fuel lines).
•DO NOT allow tow bars, tow chains, tow straps or safety chains to
rest or rub on components of your gaseous fuel injection system.

SERVICE RECOMMENDATIONS
Before you service yourBi-fuelvehicle, read and understand all
information found in theMaintenance and carechapter of your
Owner’s Guide and this supplement.
Refer to your scheduled maintenance guide for service requirements and
intervals.
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.
GASEOUS FUEL INJECTION SYSTEM SHUTOFF
When in the gaseous fuel mode under normal operating procedures, the
flow of CNG or LPG (depending upon application) is stopped when the
ignition is turned to the OFF position. The electrically operated control
valve(s) only allow the flow of fuel when the ignition is in the ON
position, with the engine running.
Liquefied petroleum gas (LPG)
If equipped with the manually-actuated supply valve(s), the flow of LPG
to the engine can be stopped by closing the supply valve located on the
LPG fuel tank(s).
If equipped, the manually-actuated supply valve(s) must be in the full
OPEN position for the engine to run on LPG.
Depending upon application, it may be necessary to remove an access
panel to close or open the supply valve(s).
Maintenance and care
