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.
197
Explorer (CTW) Canada/United States of America, enUSA, Edition date: 201902, Third-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 301).
• 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.
198
Explorer (CTW) Canada/United States of America, enUSA, Edition date: 201902, Third-Printing- Engine Emission Control

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.

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 350).
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. If the light does not
illuminate during start up, remains on or
flashes, 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 107).
Note: Indicators vary depending on region. This lamp also illuminates
momentarily when you switch
the ignition on to confirm the
lamp is functional. If it does not
illuminate when you switch the
ignition on, or 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
spun as a generator to create electrical
current. This recharges the battery and
slows the vehicle. In effect, once the
accelerator pedal is released, the motor
changes from an energy user to an energy
producer.
214
Explorer (CTW) Canada/United States of America, enUSA, Edition date: 201902, Third-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 202).
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.
Shift into gear.
Press the accelerator pedal and pull away
in a normal manner. The red warning lamp turns off.
If it remains illuminated or flashes, the
electric parking brake has not released.

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 273).
• Electronic stability control and traction
control maintain your vehicle control
in adverse conditions or high
performance driving. See
Stability
Control (page 225).
• 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 182).
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
Note:
Drive mode changes may not be
available when the ignition is off or when
the engine is not running.
Note: Button icons shown may vary from
your vehicle. Rotate the drive mode dial on the center
console to select or change a drive mode.
To select drive modes for RWD vehicles
use the console mounted control.
DRIVE MODES

TRAILER SWAY CONTROL (IF
EQUIPPED) WARNING: Turning off trailer sway
control increases the risk of loss of
vehicle control, serious injury or death.
Ford does not recommend disabling this
feature except in situations where speed
reduction may be detrimental (such as
hill climbing), the driver has significant
trailer towing experience, and can control
trailer sway and maintain safe operation.
Note: This feature does not prevent trailer
sway, but reduces it when it begins.
Note: This feature cannot stop all trailers
from swaying.
Note: In some cases, if your vehicle speed
is too high, the system may turn on multiple
times, gradually reducing your vehicle speed.
The system applies the brakes to the
individual wheels and reduces engine
torque to aid vehicle stability. If the trailer
begins to sway, the stability control
warning lamp flashes and a message
appears in the information display. See
Information Messages (page 120). Slow
your vehicle down, pull safely to the side
of the road and check for correct load
distribution. See
Load Carrying (page
281).
You can switch this feature off in the
information display. When you switch the
ignition on, the system automatically turns
on. RECOMMENDED TOWING
WEIGHTS
Note:
Do not exceed the trailer
weight for your vehicle
configuration listed in the chart
below.
Note: Be sure to take into
consideration trailer frontal area.
Do not exceed 20 ft² (1.86 m²) if
your vehicle can tow a class I
trailer, or 55 ft² (5.11 m²) if your
vehicle can tow a class III trailer
weighing more than
5,000 lb
(2,267 kg).
Note: Your vehicle could have
reduced performance when
operating at high altitudes, and
when heavily loaded or towing a
trailer. When driving at elevation,
in order to match driving
performance as perceived at sea
level, reduce gross vehicle weight
and gross combination weight by
2% per
1,000 ft (300 m) of
elevation.
