Ford Police Interceptor Sedan (2018 year). Manual — part 45

A warning lamp illuminates and
a message may appear in the
information display.

If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.

When this occurs, your vehicle still
operates, however:
•

Engine power is limited.

•

The air conditioning system turns off.

Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.

When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.

When Fail-Safe Mode Is Activated

WARNINGS

Fail-safe mode is for use during
emergencies only. Operate your
vehicle in fail-safe mode only as long

as necessary to bring your vehicle to rest
in a safe location and seek immediate
repairs. When in fail-safe mode, your
vehicle will have limited power, will not be
able to maintain high-speed operation, and
may completely shut down without
warning, potentially losing engine power,
power steering assist, and power brake
assist, which may increase the possibility
of a crash resulting in serious injury.

Never remove the coolant reservoir
cap when the engine is running or
hot.

Your vehicle has limited engine power
when in the fail-safe mode, drive your
vehicle with caution. Your vehicle does not
maintain high-speed operation and the
engine may operate poorly.

Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:

1.

Pull off the road as soon as safely
possible and switch the engine off.

2. If you are a member of a roadside

assistance program, we recommend
that you contact your roadside
assistance service provider.

3. If this is not possible, wait a short

period for the engine to cool.

4. Check the coolant level. If the coolant

level is at or below the minimum mark,
add prediluted coolant immediately.

5. When the engine temperature cools,

you can re-start the engine. Have your
vehicle checked as soon as possible to
minimize engine damage.

Note:

Driving your vehicle without repair

increases the chance of engine damage.

Engine Coolant Temperature
Management

(If Equipped)

WARNING

To reduce the risk of crash and injury,
be prepared that the vehicle speed
may reduce and the vehicle may not

be able to accelerate with full power until
the coolant temperature reduces.

If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long
or steep grade in high ambient
temperatures.

At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.

You may notice a reduction in vehicle
speed caused by reduced engine power in
order to manage the engine coolant
temperature. Your vehicle may enter this
mode if certain high-temperature and
high-load conditions take place. The
amount of speed reduction depends on
vehicle loading, grade and ambient
temperature. If this occurs, there is no
need to stop your vehicle. You can
continue to drive.

The air conditioning may automatically
turn on and off during severe operating
conditions to protect the engine from
overheating. When the coolant
temperature decreases to the normal
operating temperature, the air conditioning
turns on.

If the coolant temperature gauge moves
fully into the red zone, or if the coolant
temperature warning or service engine
soon messages appear in your information
display, do the following:

1.

Stop your vehicle as soon as it is safe
to do so. Fully apply the parking brake,
shift into park (P) or neutral (N).

2. Leave the engine running until the

coolant temperature gauge needle
returns to the normal position. After
several minutes, if the temperature
does not drop, follow the remaining
steps.

3. Switch the engine off and wait for it to

cool. Check the coolant level.

4. If the coolant level is at or below the

minimum mark, add prediluted coolant
immediately.

5. If the coolant level is normal, restart

the engine and continue.

AUTOMATIC TRANSMISSION
FLUID CHECK - 2.0L
ECOBOOST™

6F35 Transmission

The automatic transmission does not have
a transmission fluid dipstick.

The automatic transmission does not
consume fluid. If the transmission is not
working correctly, for example, the
transmission slips, shifts slowly or there
are signs of fluid leakage, have the system
checked by an authorized dealer.

Change the automatic transmission fluid
and filter at the correct service interval.

Do not use supplemental automatic
transmission fluid additives because they
are unnecessary and could lead to
transmission damage that may not be
covered by the vehicle Warranty.

AUTOMATIC TRANSMISSION
FLUID CHECK - 3.5L DURATEC/
3.5L ECOBOOST™/3.7L

6F50/6F55 Transmission

(If Equipped)

WARNING

The dipstick and surrounding
components are hot. Use gloves
when moving components and

checking the transmission fluid level.
Failure to follow this warning could result
in serious personal injury.

Note:

Automatic transmission fluid

expands when warmed. To obtain an
accurate fluid check, drive your vehicle until
you warm it up, approximately 20 mi
(30 km). If you operate your vehicle for an
extended period at high speeds, in city traffic
during hot weather or pulling a trailer, switch
your vehicle off until it reaches normal
operating temperatures to allow the fluid
to cool before checking. Depending on
vehicle use, cooling times could take up to
30 minutes or longer.

Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission
does not consume fluid. However, you
should check the fluid level if the
transmission is not working properly. For
example, if the transmission slips or shifts
slowly or if you notice some sign of a fluid
leak.

1.

Drive your vehicle 20 mi (30 km) or
until it reaches normal operating
temperature.

2. Park your vehicle on a level surface and

engage the parking brake.

3. With the parking brake engaged and

your foot on the brake pedal, start the
engine and move the gearshift lever
through all of the gear ranges. Allow a
minimum of 10 seconds for each gear
to engage.

4. Put the gearshift lever in park (P) and

leave the engine running.

Note:

For vehicles with the EcoBoost

engine, move the air filter assembly aside
to access the transmission dipstick. See
Moving the Air Filter Assembly for more
information.

5. Remove the dipstick and wipe it clean

with a dry, lint free clean rag. If
necessary, refer to the Under hood
overview in this chapter for the location
of the dipstick.

6. Install the dipstick making sure you

fully seat it in the filler tube by turning
it to the locked position.

7.

Remove the dipstick and inspect the
fluid level. The fluid should be in the
designated areas for normal operating
temperature.

(Accessing the Dipstick)

WARNING

Do not start the engine with the air
filter removed. This can cause
damage not covered by the vehicle

Warranty and can result in serious injury.

1.

Switch the engine off.

7.

Pull the air filter assembly up to
disconnect it from the seated
grommets located under the air filter
assembly.

8. Rotate the air filter assembly 90

degrees counterclockwise. Make sure
the rubber hose is still connected to the
air filter assembly.

9. Tighten the clamp.

You can now access the transmission fluid
level indicator.

Checking the fluid level

Check the transmission fluid at the normal
operating temperatures between
88°C+5°C (190°F+10°F) on a level
surface. Drive your vehicle until you warm
it up to the normal operating temperature
after approximately 20 mi (30 km).

Correct fluid level

Target the transmission fluid level within
the marked area at the normal operating
temperature between 88°C+5°C
(190°F+10°F).
