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.

Some localities mandate a sticker be displayed showing the date of the
next required inspection. In localities requiring this sticker, refueling
station technicians arenot allowedto refill your gaseous fuel tank(s) if
the sticker is not visible or if the date has expired.
Refer to the following for more information regarding gaseous fuel tank
inspection and replacement requirements.
Compressed natural gas (CNG)
For your protection, the CNG fuel tanks require visual inspection every
three years or 48 000 kilometers (30 000 miles), whichever comes first.
The purpose of the inspection is to check for damage to the fuel tank(s)
or tank wrap which may shorten the tank(s) usable life span.
CNG fuel tanks that leak or show serious damagemustbe repaired or
replaced.
The expiration date for the tank replacement is stated on each tank
label. See instructions on fuel container for inspection and service life.
Inspection and expiration dates for
the CNG fuel tank(s) are listed on
this label. Depending upon
application this label can be located
in the engine compartment, on the
fuel filler door and on the fuel
tank(s).

Liquefied petroleum gas (LPG)
For your protection, the LPG fuel tanksshouldbe visually inspected
every three years or 48 000 kilometers (30 000 miles) whichever comes
first. The purpose of the inspection is to check the tank(s) for damage or
excessive corrosion which may shorten the tank(s) usable life span.
All LPG fuel tank(s) used in Canada may require visual inspection every
five years. Contact the local authority governing the enforcement of
gaseous fuel regulations in the jurisdiction of which you refuel.
LPG fuel tanks that leak, show serious damage or excessive corrosion
mustbe repaired or replaced.
FUEL FILTER
YourBi-fuelvehicle is equipped with a separate fuel filter for the
gaseous fuel injection system. Its primary function is to remove
contaminants from the CNG or LPG fuel and trap it in the filter.
The fuel filter must be drained and/or replaced on a regular basis. 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 the 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.
