CABIN AIR FILTER
Your vehicle is equipped with a cabin air
filter, which gives you and your passengers
the following benefits:
• It improves your driving comfort by
reducing particle concentration.
• It improves the interior compartment
cleanliness.
• It protects the climate control
components from particle deposits.
You can locate the cabin air filter behind
the glove box.
Note: Make sure you have a cabin air filter
installed at all times. This prevents foreign
objects from entering the system. Running
the system without a filter in place could
result in degradation or damage to the
system. Replace the filter at regular intervals. See
Scheduled Maintenance (page 499).
For additional cabin air filter information,
or to replace the filter, see an authorized
dealer.

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.
183
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 201711, Fourth-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 262).
• 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.

Explorer (TUB) Canada/United States of America, enUSA, Edition date: 201711, Fourth-Printing Engine Emission Control

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 179).
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.

PRINCIPLE OF OPERATION
This system is a proactive system. It has
the ability to anticipate wheel slip and
transfer torque to the rear wheels before
slip occurs. Even when wheel slip is not
present, the system is continuously making
adjustments to the torque distribution, in
an attempt to improve straight line and
cornering behavior, both on and off road.
The system automatically turns on every
time you switch the ignition on.
If any component requires maintenance,
a message appears in the information
display.
USING FOUR-WHEEL DRIVE
WARNING: Vehicles with a higher
center of gravity such as utility and
four-wheel drive vehicles handle differently
than vehicles with a lower center of gravity.
Utility and four-wheel drive vehicles are
not designed for cornering at speeds as
high as passenger cars any more than
low-slung sports cars are designed to
perform satisfactorily under off-road
conditions. Avoid sharp turns, excessive
speed and abrupt maneuvers in these
vehicles. Failure to drive cautiously could
result in an increased risk of loss of vehicle
control, vehicle rollover, personal injury and
death.
The intelligent 4WD system continuously
monitors vehicle conditions and
automatically adjusts the power
distribution between the front and rear
wheels. It combines transparent
all-surface operation with highly capable
four-wheel drive. The 4WD system is always active and
requires no driver input. It is capable of
handling all road conditions, including
street and highway driving as well as
off-road and winter driving. The driver can
optimize more 4WD control by moving the
terrain management switch for the correct
terrain. See Using Terrain Control (page
202
).
Note: A warning message will be displayed
in the information display when an 4WD
system fault is present
See Information
Messages (page 119). An 4WD system fault
will cause the 4WD system to default to
front-wheel drive only mode. When this
warning message is displayed, have your
vehicle serviced at an authorized dealer
Note: A warning message will be displayed
in the information display if the 4WD system
has overheated
See Information
Messages (page 119). This condition may
occur if the vehicle was operated in extreme
conditions with excessive wheel slip, such
as deep sand. To resume normal 4WD
function as soon as possible, stop the
vehicle in a safe location and stop the
engine for at least 10 minutes. After the
engine has been restarted and the 4WD
system has adequately cooled, the warning
message will turn off and normal 4WD
function will return.
Do not use a spare tire of a different size
other than the tire provided. If the
mini-spare tire is installed, the 4WD system
may disable automatically and enter
front-wheel drive only mode to protect
driveline components. This condition will
be indicated by a warning in the
information display
See Information
Messages (page 119). If there is a warning
message in the information display from
using the spare tire, this indicator should
turn off after reinstalling the repaired or
replaced normal road tire and cycling the
ignition off and on. It is recommended to

Driving on Snow and Ice
WARNING: If you are driving in
slippery conditions that require tire chains
or cables, then it is critical that you drive
cautiously. Keep speeds down, allow for
longer stopping distances and avoid
aggressive steering to reduce the chances
of a loss of vehicle control which can lead
to serious injury or death. If the rear end of
the vehicle slides while cornering, steer in
the direction of the slide until you regain
control of the vehicle.
Note: Excessive tire slippage can cause
driveline damage.
4WD vehicles have advantages over 2WD
vehicles in snow and ice but can skid like
any other vehicle.
Should you start to slide while driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
Avoid sudden applications of power and
quick changes of direction on snow and
ice. Apply the accelerator slowly and
steadily when starting from a full stop.
Avoid sudden braking as well. Although an
4WD vehicle may accelerate better than
a two-wheel drive vehicle in snow and ice,
it won ’t stop any faster, because as in other
vehicles, braking occurs at all four wheels.
Do not become overconfident as to road
conditions.
Make sure you allow sufficient distance
between you and other vehicles for
stopping. Drive slower than usual and
consider using one of the lower gears. In
emergency stopping situations, apply the
brake steadily. Since your vehicle is
equipped with a four wheel (ABS), do not
“pump ” the brakes. See Hints on Driving
With Anti-Lock Brakes
(page 197). Maintenance and Modifications
The suspension and steering systems on
your vehicle have been designed and
tested to provide predictable performance
whether loaded or empty and durable load
carrying capability. For this reason, Ford
Motor Company strongly recommends that
you do not make modifications such as
adding or removing parts (such as lowering
kits or stabilizer bars) or by using
replacement parts not equivalent to the
original factory equipment.
Any modifications to a vehicle that raise
the center of gravity can make it more likely
the vehicle will rollover as a result of a loss
of control. Ford Motor Company
recommends that caution be used with
any vehicle equipped with a high load or
device (such as ladder or luggage racks).
Failure to maintain your vehicle properly
may void the warranty, increase your repair
cost, reduce vehicle performance and
operational capabilities and adversely
affect driver and passenger safety.
Frequent inspection of vehicle chassis
components is recommended if the vehicle
is subjected to off-highway usage.
