Ford Police Interceptor Sedan (2018 year). Manual — part 26

Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.

An improperly operating or damaged
exhaust system may allow exhaust to
enter the vehicle. Have a damaged or
improperly operating exhaust system
inspected and repaired immediately.

Do not make any unauthorized 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 intentionally remove
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
also lists engine displacement.

Please consult your warranty information
for complete details.

On-Board Diagnostics (OBD-II)

Your vehicle has a computer known as the
on-board diagnostics system (OBD-II) that
monitors the engine’s emission control
system. The system protects the
environment by making sure that your
vehicle continues to meet government
emission standards. The OBD-II system
also assists a service technician in properly
servicing your vehicle.

When the service engine soon
indicator illuminates, the OBD-II
system has detected a

malfunction. Temporary malfunctions may
cause the service engine soon indicator to
illuminate. Examples are:

1.

Your vehicle has run out of fuel—the
engine may misfire or run poorly.

2. Poor fuel quality or water in the

fuel—the engine may misfire or run
poorly.

3. The fuel fill inlet may not have closed

properly. See Refueling (page 101).

4. Driving through deep water—the

electrical system may be wet.

You can correct these temporary
malfunctions by filling the fuel tank with
good quality fuel, properly closing the fuel
fill inlet or letting the electrical system dry
out. After three driving cycles without these
or any other temporary malfunctions
present, the service engine soon indicator
should stay off the next time you start the
engine. A driving cycle consists of a cold
engine startup followed by mixed city and
highway driving. No additional vehicle
service is required.

If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may
not have symptoms that are apparent,
continued driving with the service engine
soon indicator on can result in increased
emissions, lower fuel economy, reduced
engine and transmission smoothness and
lead to more costly repairs.

Readiness for Inspection and
Maintenance (I/M) Testing

Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs
to inspect the emission control equipment
on your vehicle. Failure to pass this
inspection could prevent you from getting
a vehicle registration.

If the service engine soon
indicator is on or the bulb does
not work, your vehicle may need

service. See On-Board Diagnostics.

Your vehicle may not pass the I/M test if
the service engine soon indicator is on or
not working properly (bulb is burned out),
or if the OBD-II system has determined
that some of the emission control systems
have not been properly checked. In this
case, the vehicle is not ready for I/M
testing.

If the vehicle’s engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the
vehicle is not ready for I/M testing. To
determine if the vehicle is ready for I/M
testing, turn the ignition key to the on
position for 15 seconds without cranking
the engine. If the service engine soon
indicator blinks eight times, it means that
the vehicle is not ready for I/M testing; if
the service engine soon indicator stays on
solid, it means that your vehicle is ready
for I/M testing.

The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.

If the vehicle is not ready for I/M testing,
you can perform the following driving cycle
consisting of mixed city and highway
driving:

1.

15 minutes of steady driving on an
expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.

2. Allow your vehicle to sit for at least

eight hours with the ignition off. Then,
start the vehicle and complete the
above driving cycle. The vehicle must
warm up to its normal operating
temperature. Once started, do not turn
off the vehicle until the above driving
cycle is complete.

If the vehicle is still not ready for I/M
testing, you need to repeat the above
driving cycle.

AUTOMATIC TRANSMISSION

WARNINGS

Always apply the parking brake fully
and make sure you shift into park (P).
Switch the ignition off and remove

the key whenever you leave your vehicle.

Do not apply the brake pedal and
accelerator pedal simultaneously.
Applying both pedals simultaneously

for more than a few seconds will limit
engine performance, which may result in
difficulty maintaining speed in traffic and
could lead to serious injury.

Understanding the Positions of
Your Automatic Transmission

Putting your vehicle in or out of gear:

1.

Fully press down the brake pedal.

2. Move the gearshift lever into the

desired gear.

3. Come to a complete stop.

4. Move the gearshift lever and securely

latch it in park (P).

E206672

Park (P)

This position locks the transmission and
prevents the wheels from turning.

Reverse (R)

With the gearshift lever in reverse (R), your
vehicle will move backward. Always come
to a complete stop before shifting into and
out of reverse (R).

Neutral (N)

With the gearshift lever in neutral (N), your
vehicle can be started and is free to roll.
Hold the brake pedal down while in this
position.

Drive (D)

Drive (D) is the normal driving position for
the best fuel economy. The overdrive
function allows automatic upshifts and
downshifts through gears one through six.

Low (L)

The low (L) button is located at the end
of the column shifter. Activating low (L)
gear:
•

Provides maximum engine braking.

•

Will downshift to the lowest available
gear for the current vehicle speed;
allows for first gear when vehicle
reaches lower speeds.

•

Is not intended for use under extended
or normal driving conditions and results
in lower fuel economy.

Brake-Shift Interlock

WARNINGS

Do not drive your vehicle until you
verify that the brake lamps are
working.

When doing this procedure, you need
to take the transmission out of park
(P) which means your vehicle can

roll freely. To avoid unwanted vehicle
movement, always fully apply the parking
brake prior to doing this procedure. Use
wheels chocks if appropriate.

WARNINGS

If the parking brake is fully released,
but the brake warning lamp remains
illuminated, the brakes may not be

working properly. Have your vehicle
checked as soon as possible.

Your vehicle is equipped with a brake-shift
interlock feature that prevents moving the
gearshift lever from park (P) when the
ignition is in the on position and the brake
pedal is not pressed.

If you cannot move the gearshift lever out
of park (P) position with the ignition in the
on position and the brake pedal pressed,
a malfunction may have occurred. It is
possible that a fuse has blown or your
vehicle’s brake lamps are not operating
properly. See Fuse Specification Chart
(page 162).

If the fuse is not blown and the brake
lamps are working properly, the following
procedure will allow you to move the
gearshift lever from park (P):

1.

Apply the parking brake. Turn the
ignition key to the off position, then
remove the key.

2. Move the steering column to the full

down and full rearward position
(toward the driver’s seat).

3. Remove the gearshift lever boot.

4. Place fingers into gearshift lever boot

hole and pull top half of shroud up and
forward to separate it from the lower
half of the shroud. There is a hinge at
the forward edge of the top shroud.
Roll the top half of the shroud upward
on the hinge point to clear the hazard
flasher button, then pull straight
rearward toward the driver’s seat to
remove.

5. Remove the top half of the shroud.

6. Remove the three fasteners under the

column that secure the lower shroud
half to the column.

7.

Pull the tilt steering lock lever into the
full unlocked position and remove the
lower shroud cover by pulling the lever
handle through the slot in the cover.

8. Apply the brake, pull the white disk

then move the shifter to neutral (N).

9. Start your vehicle.

Perform Steps 4 through 8 in reverse order,
making sure to engage the hinge pivots
between the upper and lower halves of the
shroud. Keep slight pressure in the forward
direction as the halves rotate together.

See your authorized dealer as soon as this
procedure is used.
