STARTING A GASOLINE
ENGINE
When you start the engine, the idle speed
increases. This helps to warm up the
engine. If the engine idle speed does not
slow down automatically, have your
vehicle checked by an authorized dealer. Note:
You can crank the engine for a total
of 60 seconds without the engine starting
before the starting system temporarily
disables. The 60 seconds does not have to
be all at once. For example, if you crank the
engine three times for 20 seconds each
time, without the engine starting, you
reached the 60-second time limit. A
message appears in the information display
alerting you that you exceeded the cranking
time. You cannot attempt to start the
engine for at least 15 minutes. After 15
minutes, you are limited to a 15-second
engine cranking time. You need to wait 60
minutes before you can crank the engine for
60 seconds again.
Before starting your vehicle, check the
following:
• Make sure all occupants have fastened
their safety belts.
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on.
• Make sure the transmission is in park
(P).
• Switch the ignition on. For vehicles with
a keyless ignition, see the following
instructions.
Vehicles with an Ignition Key
Note: Do not touch the accelerator pedal.
1. Fully depress the brake pedal.
2. Turn the key to the start position to start the engine.
Note: The engine may continue cranking
for up to 15 seconds or until it starts.
Note: If you cannot start the engine on the
first try, wait for a short period and try again.

Automatic Engine Shutdown
For vehicles with a keyless ignition, this
feature automatically shuts down the
engine if it has been idling for an extended
period. The ignition also turns off in order
to save battery power. Before your vehicle
shuts down, a message appears in the
information display showing a timer
counting down from 30 seconds. If you do
not intervene within 30 seconds, your
vehicle shuts down. Another message
appears in the information display to
inform you that your vehicle has shut down
to save fuel. Start your vehicle as you
normally do.
Automatic Engine Shutdown Override
Note:
You cannot permanently switch off
the automatic shutdown feature. When you
switch it off temporarily, it turns on at the
next ignition cycle.
You can stop the shutdown, or reset the
timer, at any point before the 30-second
countdown has expired by doing any of the
following:
• You can reset the timer by interacting
with your vehicle, for example pressing
the brake or accelerator pedal.
• You can temporarily switch off the
shutdown feature any time the ignition
is on using the information display. See
Information Displays (page 99). The
feature only remains off for the current

Guarding Against Exhaust Fumes WARNING
If you smell exhaust fumes inside
your vehicle, have your vehicle
checked by your authorized dealer
immediately. Do not drive your vehicle if
you smell exhaust fumes. Carbon
monoxide is present in exhaust fumes.
Take precautions to avoid its dangerous
effects. Important Ventilating Information
If you stop your vehicle and then leave the
engine idling for long periods, we
recommend that you do one of the
following:
•
Open the windows at least 1 in (3 cm).
• Set your climate control to outside air.
ENGINE BLOCK HEATER (If
Equipped) WARNINGS
Failure to follow engine block heater
instructions could result in property
damage or serious personal injury.
Do not use your heater with
ungrounded electrical systems or
two-pronged adapters. There is a risk
of electrical shock. Do not fully close the hood, or allow
it to drop under its own weight when
using the engine block heater. This
could damage the power cable and may
cause an electrical short resulting in fire,
injury and property damage. Note:
The heater is most effective when
outdoor temperatures are below 0°F
(-18°C).
The heater acts as a starting aid by
warming the engine coolant. This allows
the climate control system to respond
quickly. The equipment includes a heater
element (installed in the engine block) and
a wire harness. You can connect the
system to a grounded 120-volt AC
electrical source.
We recommend that you do the following
for a safe and correct operation:
• Use a 16-gauge outdoor extension cord
that is product certified by
Underwriter ’s Laboratory (UL) or
Canadian Standards Association
(CSA). This extension cord must be
suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard.
• Use as short an extension cord as
possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the
extension cord plug and heater cord
plug connections are free and clear of
water. This could cause an electric
shock or fire.
• Make sure your vehicle is parked in a
clean area, clear of combustibles.
• Make sure the heater, heater cord and
extension cord are firmly connected.
• Check for heat anywhere in the
electrical hookup once the system has
been operating for approximately 30
minutes.
166
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Starting and Stopping the Engine

Some fuel stations, particularly those in
high altitude areas, offer fuels posted as
regular unleaded gasoline with an octane
rating below 87. We do not recommend
these fuels.
For best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather as well
as other conditions, for example when
towing a trailer. See Towing (page 238).
Do not use any fuel other than those
recommended because they could lead to
engine damage that will not be covered by
the vehicle Warranty.
Note: Use of any fuel other than those
recommended can impair the emission
control system and cause a loss of vehicle
performance.
Do not use:
• Diesel fuel.
• Fuels containing kerosene or paraffin.
• Fuels containing more than 85%
ethanol or E100 fuel.
• Fuels containing methanol.
• Fuels containing metallic-based
additives, including manganese-based
compounds.
• Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Leaded fuel (using leaded fuel is
prohibited by law).
The use of fuels with metallic compounds
such as methylcyclopentadienyl
manganese tricarbonyl (commonly known
as MMT), which is a manganese-based
fuel additive, will impair engine
performance and affect the emission
control system. Do not be concerned if the engine
sometimes knocks lightly. However, if the
engine knocks heavily while using fuel with
the recommended octane rating, contact
an authorized dealer to prevent any engine
damage.
Switching Between E85 and
Gasoline
We do not recommend repeatedly
alternating between E85 and gasoline. If
you switch from using E85 to gasoline, or
from gasoline to E85, add as much fuel as
possible, at least half a tank. Drive your
vehicle immediately for a minimum of 5 mi
(8 km)
to allow it to adapt to the change
in ethanol concentration. If you use E85
exclusively, we recommend that you fill
the fuel tank with regular unleaded
gasoline at each scheduled oil change.
FUEL FILLER FUNNEL
LOCATION
The fuel filler funnel is located in the spare
wheel storage tray.
RUNNING OUT OF FUEL
Running out of fuel can cause damage not
covered by the vehicle Warranty.
If your vehicle runs out of fuel:
• Add a minimum of
1.3 gal (5 L) of fuel
to restart the engine. If your vehicle is
out of fuel and on a steep slope, more
fuel may be required.
• You may need to switch the ignition
from off to on several times after
refueling to allow the fuel system to
pump the fuel from the tank to the
engine. When restarting, cranking time
takes a few seconds longer than
normal.

Note:
When you insert the correct size fuel
pump nozzle a spring loaded inhibitor will
open.
2. Insert the fuel pump nozzle up to the first notch on the nozzle A. Keep it
resting on the cover of the fuel tank
filler pipe opening. 3. Hold the fuel pump nozzle in position
B when refueling. Holding the fuel
nozzle in position A can affect the flow
of fuel and shut off the fuel nozzle
before the fuel tank is full. 4. Operate the fuel pump nozzle within
the area shown. 5.
Slightly raise the fuel pump nozzle and
then slowly remove it.
6. Fully close the fuel tank filler door.
Note: Do not attempt to start the engine
if you have filled the fuel tank with incorrect
fuel. Incorrect fuel use can cause damage
not covered by the vehicle Warranty. Have
your vehicle checked immediately.
System Warnings (If Equipped)
If the fuel filler inlet does not fully close a
warning message appears in the
information display.
1. Stop your vehicle as soon as safely possible and shift the transmission into
park (P) or neutral (N).
2. Apply the parking brake and switch the
ignition off.
3. Fully open the fuel tank filler door until
it engages.
4. Check the fuel filler inlet and the area around it for any items or debris that
may be obstructing its movement.

5. Insert a fuel pump nozzle or the fuel
filler funnel provided with your vehicle
in to the fuel tank filler pipe opening.
This action should dislodge any debris
that may be preventing the fuel filler
inlet from fully closing.
Note: If this action corrects the problem
the message may not reset immediately. If
the message remains and the service engine
soon warning lamp appears in the
information display, have your vehicle
checked as soon as possible.
FUEL CONSUMPTION
Empty reserve is the amount of fuel
remaining in the tank after the fuel gauge
indicates empty. The amount of usable
fuel in the empty reserve varies and should
not be relied upon to increase driving range.
• The usable capacity of the fuel tank is
the amount of fuel that you can add to
the fuel tank when the fuel gauge
indicates empty, before the first fuel
filler nozzle automatic shutoff event.
• The advertised capacity is equal to the
volumetric difference between actual
fuel fill before the first fuel filler nozzle
automatic shutoff event and the fuel
quantity when the fuel gauge indicates
empty. See Capacities and
Specifications (page 332). It is the
usable capacity minus the empty
reserve.
• Due to the empty reserve, you may be
able to add more fuel than the
advertised capacity of the fuel tank
when the fuel gauge indicates empty. Filling the Fuel Tank
For consistent results when refueling:
•
Turn the ignition off before fueling; an
inaccurate reading results if the engine
is left running.
• Use the same fill rate
(low-medium-high) each time the tank
is filled.
• Allow no more than one automatic
shut-off when refueling.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the
first
1,000 mi (1,600 km) of driving (this is
your engine ’s break-in period). A more
accurate measurement is obtained after
2,000 mi (3,200 km)
to 3,000 mi
(4,800 km). Also, fuel expense, frequency
of fill ups or fuel gauge readings are not
accurate ways to measure fuel economy.
1. Fill the fuel tank completely and record
the initial odometer reading.
2. Each time you fill the fuel tank, record the amount of fuel added.
3. After at least three fill ups, fill the fuel tank and record the current odometer
reading.
4. Subtract your initial odometer reading from the current odometer reading.
To calculate L/100 km (liters per 100
kilometers) fuel consumption, multiply the
liters used by 100, then divide by kilometers
traveled. To calculate MPG (miles per
gallon) fuel consumption, divide miles
traveled by gallons used.
174
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Fuel and Refueling

Keep a record for at least one month and
record the type of driving (city or highway).
This provides an accurate estimate of your
vehicle
’s fuel economy under current
driving conditions. Keeping records during
summer and winter will show how
temperature impacts fuel economy.
Conditions
• Heavily loading your vehicle reduces
fuel economy.
• Carrying unnecessary weight in your
vehicle may reduce fuel economy.
• Adding certain accessories to your
vehicle such as bug deflectors, rollbars
or light bars, running boards and ski
racks may reduce fuel economy.
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures.
• Fuel economy may decrease when
driving short distances.
• You will get better fuel economy when
driving on flat terrain than when driving
on hilly terrain.
EMISSION CONTROL SYSTEM WARNINGS
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. 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:
•
Use only the specified fuel listed.
• Avoid running out of fuel.
• Do not turn off the ignition while your
vehicle is moving, especially at high
speeds.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
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.
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
175
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Fuel and Refueling

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 171).
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
176
Explorer (TUB) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Fuel and Refueling

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.
