Running Out of Fuel
*
[MC36200( ALL)01/96]
If your vehicle runs out of fuel, try to stop on
level ground away from traffic. Add at least two
gallons (8 liters) of fuel to start your vehicle
again. If your vehicle is not on level ground,
you may need as much as five gallons (20 liters)
of fuel to start it.
*
[MC36300( ALL)01/96]
You may need to crank the engine several times
before the fuel system starts to pump fuel from
the tank to the engine.

Fuel Economy
*
[MC36500( ALL)01/96]
Fuel economy is an estimate of the efficiency of
your vehicle and can be calculated as Miles Per
Gallon (MPG) or Liters Per 100 Kilometers
(L/100K).
*
[MC36600( ALL)01/96]
Do not calculate fuel economy during your
vehicle's break-in period. This would not be an
accurate estimate of how much fuel your vehicle
will normally use.
*
[MC36700( ALL)01/96]
To calculate fuel economy:
*
[MC36800( ALL)01/96]
1. Fill the tank completely and record the
initial odometer reading.
*
[MC36900( ALL)01/96]
2. Every time you buy fuel record the
amount (in gallons or liters) purchased.
*
[MC37000( ALL)01/96]
3. After at least three to five tankfuls, fill the
fuel tank and record the final odometer
reading.

Improving Fuel Economy
*
[MC37800( ALL)01/96]
Fuel economy is affected by a number of
variables which can reduce efficiency. You can
improve fuel economy by understanding these
variables and minimizing their effect.
*
[MC37900( ALL)01/96]
The following decrease fuel economy:
*
[MC38000( ALL)01/96]

Emission Control System
*
[MC38975( ALL)01/96]
RWARNING
Exhaust leaks may result in the entry of
harmful and potentially lethal fumes into
the passenger compartment. Under
extreme conditions excessive exhaust
temperatures could damage the fuel
system, the interior floor covering, or
other vehicle components, possibly
causing a fire.
[MC39025( M)01/96]
To make sure that the emissions control parts
continue to work properly:
*
[MC39075( ALL)01/96]
q
Avoid running out of fuel.
*
[MC39100( ALL)01/96]
q
Do not turn off the ignition while your
vehicle is moving, especially at high speeds.
*
[MC39125( ALL)01/96]
q
Have the services listed in theMaintenance
Schedule and Recordbooklet performed
according to the specified schedule. The
scheduled maintenance services are required
because they are considered essential to the
life and performance of your vehicle and to
its emissions system.
*
[MC39150( ALL)01/96]
In general, maintenance, replacement, or service
of the emissions control devices or systems in
your new Ford Motor Company vehicle or
engine may be performed at your expense by
any automotive repair establishment or
individual using automotive parts equivalent to
those which your vehicle or engine was
originally equipped.

[MC39175( ALL)01/96]
RWARNING
Do not park, idle, or drive your vehicle in
dry grass or other dry ground cover. The
emission system heats up the engine
compartment and exhaust system, which
can start a fire.
*
[MC39225( ALL)01/96]
If other than Ford or Motorcraft or Ford
authorized remanufactured parts are used for
maintenance, replacement, or for the service of
components affecting emissions control, the
owner should be assured that such parts are
warranted by their manufacturer to be
equivalent to genuine Ford Motor Company
parts in performance and durability. Please
consult your warranty information booklet for
complete warranty information.
*
[MC39275( ALL)01/96]
Do not make any unauthorized changes to your
vehicle or engine. Changes that cause more
unburned fuel to reach the exhaust system can
increase the temperature of the engine or
exhaust system.
*
[MC39300( ALL)01/96]
By law, anyone who manufactures, repairs,
services, sells, leases, trades vehicles, or
supervises a fleet of vehicles is not permitted to
intentionally remove an emission control device
or prevent it from working. In some of the
United States and in Canada, vehicle owners
may be liable if their emission control device is
removed or is prevented from working.
*
[MC39325( ALL)01/96]
Do not drive your vehicle if it does not operate
properly. See your dealer if the engine runs on
for more than five seconds after you shut it off
or if it misfires, surges, stalls, or backfires.

Readiness for Inspection/Maintenance
Testing
*
[MC39825( ALL)01/96]
In some localities it may become a legal
requirement to pass an
Inspection/Maintenance (I/M) test of the
On-Board Diagnostic (OBD) II system. If the
vehicle's powertrain system or its battery has
just been serviced, the OBD II system is reset to
a not ready for I/M testing condition. To
prepare for I/M testing, the law specifies a
ªneed for additional mixed city and highway
driving to complete the checkº of the OBD II
system. As soon as all of the OBD II system
checks are successfully completed, the OBD II
system is set to the ready condition. The amount
of driving required to reach the ready condition
varies with individual driving patterns. To
complete this requirement in the minimum
amount of time, refer to the OBD II Drive Cycle
defined below. If the vehicle owner cannot or
does not want to do the additional driving
required by law, a service center can perform
this drive cycle as it would any other type of
repair work.
*
[MC39850( ALL)01/96]
OBD II Drive Cycle
*
[MC39875( ALL)01/96]
The engine must be warmed up and at
operating temperature before proceeding with
the drive modes of the following OBD II Drive
Cycle.
*

1. Start the engine. Drive or idle (in neutral)
the vehicle for 4 minutes.
[MC39925( ALL)01/96]
