service reset FORD SUPER DUTY 2003 1.G Owners Manual

The appearance of your vehicle’s trip computer may differ depending on
your vehicle’s option package, but the functions are the same.
The trip computer onlyoperates with the ignition in the ON position.
Trip computer features are as follows:
Selectable features
English/metric display
Press this control to change the trip
computer displaybetween metric
and English units.
Mode control
Each press of the MODE control will
displaya different feature as follows:
Average fuel economy.The
displaywill indicate the vehicle’s
average fuel economyin liters/100
km (or miles/gallon) since the
average fuel economywas last reset.
If you calculate your average fuel
economybydividing liters of fuel used by100 kilometers traveled (miles
traveled by gallons used), your figure may be different than displayed for
the following reasons:
•your vehicle was not perfectly level during fill-up
•differences in the automatic shut-off points on the fuel pumps at
service stations
•variations in top-off procedure from one fill-up to another
•rounding of the displayed values to the nearest liter (gallon)
To reset the average fuel economy:
1. Press the MODE control repeatedlyuntil average fuel economyis
displayed (this is the only resettable display).

•Tires have their maximum inflation pressure and associated load rating
imprinted on the tire sidewall. This pressure mayor maynot be the
same as that shown as recommended on the vehicle. The vehicle
operator mayhave to adjust the tire inflation pressure to
accommodate the snowplow and payload. Consult your dealer or
equipment installer for help with proper inflation pressures.
•Federal and some local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your dealer for additional
information.
•After installing a snowplow to the vehicle, ensure the vehicle’s front
toe alignment and front ride height are within specification (reset if
required). These specifications are located in the vehicle’s Workshop
Manual.
Note:Do not exceed the GVWR or the GAWR specified on the
certification label.
Removing snowplow
After removing a snowplow from the vehicle, ensure the vehicle’s front toe
alignment and front ride height are within specification (reset if required).
Snowplowing with your air bag-equipped vehicle
Your vehicle is equipped with a driver and passenger air bag
Supplemental Restraint System (SRS) The SRS is designed to activate in
certain frontal and offset frontal collisions when the vehicle sustains
sufficient longitudinal deceleration.
Careless or high speed driving while plowing snow which results in
sufficient vehicle decelerations can deploythe air bag. Such driving also
increases the risk of accidents.
All occupants of the vehicle, including the driver, should always
properlywear their safetybelts, even when an air bag (SRS) is
provided.
Never remove or defeat the “tripping mechanisms” designed into the
snow removal equipment byits manufacturer. Doing so maycause
damage to the vehicle and the snow removal equipment as well as
possible air bag deployment.
Do not attempt to service, repair, or modifythe Air Bag
Supplemental Restraint System or its fuses. See your Ford or
Lincoln Mercurydealer.

•Decreased engine coolant concentrations below 40% will
decrease the corrosion protection characteristics of the engine
coolant and may cause engine damage.
•Decreased engine coolant concentrations below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.
•Refer to the chart on the coolant container to ensure the
coolant concentration in your vehicle will provide adequate
protection at the temperatures in which you drive.
Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
What you should know about fail-safe cooling (if equipped)
If the engine coolant supplyis depleted, this feature allows the vehicle to
be driven temporarilybefore incremental component damage is incurred.
The “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.
How fail-safe cooling works
If the engine begins to overheat:
•The engine coolant temperature
gauge will move to the red (hot)
area.
•The
andsymbol will
illuminate.
•TheService Engine Soon
indicator light will illuminate.
If the engine reaches a preset
over-temperature condition, the engine will automaticallyswitch to
alternating cylinder operation. Each disabled cylinder acts as an air
pump and cools the engine.
When this occurs the vehicle will still operate. However:
•The engine power will be limited.
•The air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completelyshut down, causing steering and braking effort to
increase.

Exhaust leaks mayresult in entryof harmful and potentially
lethal fumes into the passenger compartment.
Do not make anyunauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionallyremove an emission control device or prevent
it from working. Information about your vehicle’s emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal identifies engine displacement and gives some tune up
specifications.
Please consult yourWarranty Guidefor complete emission warranty
information.
Readiness for Inspection/Maintenance (I/M) testing
In some localities, it maybe a legal requirement to pass an I/M test of
the on-board diagnostics system. If your “Check Engine/Service Engine
Soon” light is on, refer to the description in theWarning lights and
chimessection of theInstrument clusterchapter. Your vehicle maynot
pass the I/M test with the “Check Engine/Service Engine Soon” light on.
If the vehicle’s powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a “not ready for I/M test”
condition. To readythe on-board diagnostics system for I/M testing, a
minimum of 30 minutes of cityand highwaydriving is necessaryas
described below:
•First, at least 10 minutes of driving on an expresswayor highway.
•Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
