lights LINCOLN BLACKWOOD 2003 Bi Fuel Supplement Manual

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.
