REFUELING - HYBRID
ELECTRIC VEHICLE (HEV) WARNING: When refueling always
shut the engine off and never allow
sparks or open flames near the fuel tank
filler valve. Never smoke or use a cell
phone while refueling. Fuel vapor is
extremely hazardous under certain
conditions. Avoid inhaling excess fumes. WARNING:
The fuel system may
be under pressure. If you hear a hissing
sound near the fuel filler inlet, do not
refuel until the sound stops. Otherwise,
fuel may spray out, which could cause
serious personal injury. WARNING:
Do not pry open the
fuel tank filler valve. This could damage
the fuel system. Failure to follow this
instruction could result in fire, personal
injury or death. WARNING: Do not remove the fuel
pump nozzle from its fully inserted
position when refueling. WARNING:
Stop refueling when
the fuel pump nozzle automatically
shuts off for the first time. Failure to
follow this will fill the expansion space
in the fuel tank and could lead to fuel
overflowing. WARNING:
Do not overfill the fuel
tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray
and fire. WARNING:
Wait at least five
seconds before removing the fuel pump
nozzle to allow any residual fuel to drain
into the fuel tank. WARNING: Read and follow all the
instructions on the pump island.
1. When you stop your vehicle, shift into park (P) and switch the ignition off. 133

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the
vehicle from the engine and exhaust
system heat and noise. On vehicles with
no original equipment floor covering
insulation, do not carry passengers in a
manner that permits prolonged skin
contact with the metal floor. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors or the Diesel
Exhaust Fluid system can result in reduced
engine power and the illumination of the
service engine soon light. Tampering With a Noise Control
System
Federal laws prohibit the following acts:
•
Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.
The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.
137
Explorer (CTW) Police, Canada/United States of America, Police, enUSA, Edition date: 202007, Second-Printing Engine Emission Control

•
Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for
climactic conditions.
Note: Some vehicles have a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
Note: If these checks do not help you
correct the concern, have your vehicle
checked as soon as possible.
Noise Emissions Warranty,
Prohibited Tampering Acts and
Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb
(4,536 kg) Gross Vehicle Weight Rating
(GVWR). The preceding statements
concerning prohibited tampering acts and
maintenance, and the noise warranty
found in the Warranty Guide, are
applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR.
CATALYTIC CONVERTER WARNING:
Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off. WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable
exhaust emission standards.
To make sure that the catalytic converter
and other emission control components
continue to work properly:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle
(page 196).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.
If you use anything other than Ford,
Motorcraft or Ford-authorized parts for
maintenance replacements or for service
of components affecting emission control,
such non-Ford parts should be equivalent
to genuine Ford Motor Company parts in
performance and durability.

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.

AWD vehicles are equipped for driving on
sand, snow, mud and rough roads and have
operating characteristics that are
somewhat different from conventional
vehicles, both on and off the highway.
Under severe operating conditions, the A/C
may cycle on and off to protect
overheating of the engine.
Basic operating principles in special
conditions
•
Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.
If Your Vehicle Goes Off the Edge of the
Pavement
• If your vehicle goes off the edge of the
pavement, slow down, but avoid severe
brake application, ease the vehicle
back onto the pavement only after
reducing your speed. Do not turn the
steering wheel too sharply while
returning to the road surface.
• It may be safer to stay on the apron or
shoulder of the road and slow down
gradually before returning to the
pavement. You may lose control if you
do not slow down or if you turn the
steering wheel too sharply or abruptly.
• It often may be less risky to strike small
objects, such as highway reflectors,
with minor damage to your vehicle
rather than attempt a sudden return to
the pavement which could cause the
vehicle to slide sideways out of control
or rollover. Remember, your safety and
the safety of others should be your
primary concern. If Your Vehicle Gets Stuck WARNING: Apply the parking
brake, shift into park (P), switch the
ignition off and remove the key before
you leave your vehicle. Failure to follow
this instruction could result in personal
injury or death. WARNING:
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. WARNING:
Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
If your vehicle gets stuck in mud or snow it
may be rocked out by shifting between
forward and reverse gears, stopping
between shifts, in a steady pattern. Press
lightly on the accelerator in each gear.
If your vehicle has AdvanceTrac® with Roll
Stability Control ™, it may be beneficial to
disengage the AdvanceTrac® with Roll
Stability Control ™ system while
attempting to rock the vehicle.
Note: Do not rock the vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock the vehicle for more than
a few minutes or damage to the
transmission and tires may occur or the
engine may overheat.
Emergency Maneuvers
• In an unavoidable emergency situation
where a sudden sharp turn must be
made, remember to avoid
"over-driving" your vehicle (that is, turn
the steering wheel only as rapidly and
as far as required to avoid the
emergency). Excessive steering will

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out and an
authorized dealer should check them. If the
vehicle has continuous vibration or shudder
in the steering wheel while braking, an
authorized dealer should check your vehicle.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 242).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Switch the engine off, move the
transmission to park (P) and apply the
parking brake. Inspect the accelerator
pedal and the area around it for any items
or debris that may be obstructing its
movement. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at
which you press the brake pedal. It
provides maximum braking efficiency as
long as you press the pedal. Emergency
brake assist can reduce stopping distances
in critical situations. Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily
illuminates when you switch the
ignition on or apply the parking
brake. If the light does not illuminate
during start up, remains on or flashes,
except when you switch the ignition on or
apply the parking brake, the anti-lock
braking system may be disabled. Have the
system checked by an authorized dealer.
If the anti-lock brake system is disabled,
normal braking is still effective. See
Warning Lamps and Indicators (page
79).
Note: Indicators vary depending on region. This lamp also illuminates
momentarily when you switch
the ignition on or apply the
parking brake to confirm the
lamp is working. If it does not
illuminate when you switch the
ignition on, apply the parking brake, or if it
begins to flash at any time, have the
system checked by an authorized dealer.
If the brake warning lamp illuminates with
the parking brake released, have the
system checked immediately.
Regenerative Braking System
This feature is used to simulate the engine
braking of an internal combustion engine
and assist the standard brake system while
recovering some of the energy of motion
and storing it in the battery to improve fuel
economy. The standard brake system is
designed to fully stop the car if
regenerative braking is not available.
During regenerative braking, the motor is
151
Explorer (CTW) Police, Canada/United States of America, Police, enUSA, Edition date: 202007, Second-Printing Brakes E270480

If it continues to flash or does not
illuminate, the system has malfunctioned.
Have your vehicle checked as soon as
possible.
Note:
You can apply the electric parking
brake when the ignition is off.
Note: The electric parking brake could
automatically apply when you shift into park
(P). See Transmission (page 142).
Applying the Electric Parking Brake in
an Emergency
Note: Do not apply the electric parking
brake when your vehicle is moving, except
in an emergency. If you repeatedly use the
electric parking brake to slow or stop your
vehicle, you could cause damage to the
brake system.
You can use the electric parking brake to
slow or stop your vehicle in an emergency. Pull the switch upward and hold
it.
The red warning lamp
illuminates, a tone sounds and
the stoplamps turn on.
The electric parking brake continues to
slow your vehicle down unless you release
the switch.
Manually Releasing the Electric
Parking Brake
Switch the ignition on.
Press and hold the brake pedal.
Push the switch downward.
The red warning lamp turns off. If it remains illuminated or flashes, the
system has malfunctioned. Have your
vehicle checked as soon as possible.
Pulling Away on a Hill When Towing a
Trailer
Press and hold the brake pedal.
Pull the switch upward and hold
it.
Shift into gear.
Press the accelerator pedal until engine
has developed sufficient torque to prevent
your vehicle from rolling down the hill. Release the switch and pull
away in a normal manner.
Automatically Releasing the
Electric Parking Brake
Close the driver door.

WHAT IS DRIVE MODE
CONTROL
The system delivers a driving experience
through a suite of sophisticated electronic
vehicle systems. These systems optimize
steering, handling and powertrain
response. This provides a single location
to control multiple systems performance
settings.
Changing the drive mode changes the
functionality of the following systems:
•
Electric power-assisted steering
system adjusts steering effort and feel
based on the mode you select. See
Steering (page 174).
• Electronic stability control and traction
control maintain your vehicle control
in adverse conditions or high
performance driving. See
Stability
Control (page 157).
• Electronic throttle control enhances
the powertrain response to your driving
inputs.
• Transmission controls become
optimized with shift schedules tuned
to each mode.
• Four-wheel drive settings are optimized
and tuned to each mode.
• Electric vehicle mode selections may
be limited. See
Hybrid Vehicle
Operation (page 123).
The system tailors your vehicle
configuration for each mode you select.
Note: Not all settings may be available.
Note: The system has diagnostic checks
that continuously monitor the system for
proper operation. If a mode is unavailable
due to a system fault or change in gear
shifter position, the mode defaults to
Normal. SELECTING A DRIVE MODE
Police Pursuit Mode This mode does not use a switch.
This system is a temporary
driving enhancement that senses
the driver is demanding high performance
from the vehicle. On all Police Interceptor
applications, the transmission holds lower
gears and the engine holds higher engine
speeds longer than normal driving. The
mode terminates when the vehicle senses
the driver is no longer in high performance
demand. The vehicle then returns to
normal operation.
Note: Drive mode changes may not be
available when the ignition is off or when
the engine is not running. Press the drive mode button underneath
the information display to select or change
a drive mode.
DRIVE MODES
Deep Snow/Sand
For snow or soft dry sand. When
stuck in deep snow, use this
mode to help get unstuck.
Note: Using deep snow/sand mode on dry,
hard surfaces could produce some vibration,
driveline bind up, and potential excessive
tire wear. This mode is for slippery and loose
surfaces.

Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in park (P) to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow. 2. Set your vehicle parking brake.
3. Place the automatic transmission in
park (P).
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not
included with vehicle.)
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.

REDUCED ENGINE
PERFORMANCE
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop
without warning. Failure to follow this
instruction could result in the loss of
control of your vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position,
the engine is overheating. See Gauges
(page 78).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on
ambient temperature, vehicle load and
terrain. The engine continues to operate
with limited power for a short period of
time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually.
1. Gradually reduce your speed and stop your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See
Engine
Coolant Check (page 226).
5. Have your vehicle checked as soon as possible.
ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle. You may improve your fuel economy by
keeping these things in mind:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds (traveling
at
55 mph (88 km/h) uses 15% less
fuel than traveling at 65 mph
(105 km/h)).
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Revving the engine before switching it
off.
• Idle for periods longer than one minute.
• Warm up your vehicle on cold
mornings.
• Use the air conditioner or front
defroster.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while
driving.
• Drive a heavily loaded vehicle or tow a
trailer.
