Introduction

ABOUT THIS SUPPLEMENT

This booklet supplements your Owner Guide and is part of the owner’s
portfolio. It describes the operation of your natural gas vehicle (NGV)
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 Guide. Please read this supplement carefully and
completely. Refer to the Owner 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 your NGV. For further
information, refer to your Warranty Information Booklet.

Specified maintenance procedures must be followed. Repairs must be
made by trained personnel.

It is important that your NGV be properly maintained by qualified Ford
trained gaseous fuel service technicians. If a problem occurs, it is
important that properly trained personnel diagnose and repair the cause.
If the problem relates to the fuel system, proper part replacement is
imperative to keep your vehicle operating correctly. NGV fuel system
components and standard gasoline fuel system components are not
interchangeable. If your NGV is not maintained in accordance with
approved service procedures, damage may occur and your warranty may
be invalidated.

Any modification to the fuel system of your NGV voids the Ford New
Vehicle Limited Warranty.

Introduction

COMPRESSED NATURAL GAS (CNG) FUEL SYSTEM

Your vehicle is equipped with a dedicated compressed natural gas (CNG)
fuel system that is under high pressure.

Depending upon the application, the CNG fuel system is rated at a pressure
of 20,700 kPa (3,000 psi) at 21°C (70°F) or 24,800 kPa (3,600 psi) at
21°C (70°F). Refer to the label on the fuel filler door to determine the
fuel system pressure rating.

Use caution when servicing or maintaining any of the components of the
CNG fuel system.

Service to high-pressure fuel system components must be

conducted only at qualified dealerships by qualified technicians.
Failure to do so may cause damage to components or cause bodily
harm.

On F-150 Heritage natural gas vehicles, do not modify or replace the
bed with any non-OEM components. Should the bed need to be removed
for service or replacement, it should be done by a qualified dealership
using qualified technicians. Do not sit, stand or place heavy loads on the
in-bed or in-vehicle tank covers. Any bed cap added to this vehicle must
be well ventilated. Failure to provide adequate ventilation could result in
gas vapor build up over time potentially resulting in a combustible
mixture.

FUSES/ELECTRICAL SYSTEMS

NGV fuse strategy may be different than a non-NGV. Consult the Fuses
and Relays section in the Roadside emergencies chapter of your

Owner’s Guide for differences.

FUEL GAUGE

The fuel gauge in your NGV behaves similarly to a typical gasoline fuel
gauge. However, the gauge operation is based on the pressure and
temperature of the natural gas, not on the level of liquid gasoline.
Depending upon application, a fuel gauge reading of Full 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). The NGV fuel gauge will
provide a linear reading from this point down to Empty. Refer to the
Fueling section of this supplement for more information on fuel gauge
performance during the fast-fill method of fueling.

CNG FUEL SYSTEM COMPONENT IDENTIFICATION

The following illustrations depict the major unique components of the
CNG fuel system. All of these unique components are constructed of
special materials that withstand the effects of CNG. NEVER replace a
unique CNG fuel system component with a standard gasoline fuel system
component or any aftermarket component.
