Description and Action
Message
A warning message appears
in the information display
when the fuel system fails
to depressurize or the fuel
filler door fails to open. You
may have to use the fuel
filler door manual override
lever.
Refuel
Error See
Manual
If the information message appears, do the
following:
1. Check the fuel filler door for anything that may be obstructing its movement,
for example ice or snow.
2. Remove any obstruction from the fuel filler door.
3. Press the button on the driver door to open the fuel filler door.
4. If the fuel filler door fails to open and the information message remains in
the information display, use the fuel
filler door manual override lever.
Fuel Filler Door Manual Override
Lever 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.
Note: The transmission must be in park (P)
or neutral (N).
When using the manual override lever do
the following:
1. Switch the ignition on. Note:
The manual override lever is in the
driver side rear wheel well area.
2. Pull the manual override lever.
3. Switch the ignition off.
4. Complete the refueling process within 20 minutes.
FUEL CONSUMPTION
Advertised Capacity
The advertised capacity is the maximum
amount of fuel that you can add to the fuel
tank when the fuel gauge indicates empty.
See
Capacities and Specifications
(page 391).
194
Explorer (CTW), enUSA, Edition date: 202007, Second-Printing Fuel and RefuelingE297793

In addition, the fuel tank contains an empty
reserve. The empty reserve is an
unspecified amount of fuel that remains
in the fuel tank when the fuel gauge
indicates empty.
Note:
The amount of fuel in the empty
reserve varies and should not be relied upon
to increase driving range.
Calculating Fuel Economy
Your vehicle calculates fuel economy
figures through the trip computer average
fuel function. See Information Displays
(page 112).
The first
1,000 mi (1,600 km) of driving is
the break-in period of the vehicle. A more
accurate measurement is obtained after
2,000– 3,000 mi (3,200–4,800 km)
.
1. Completely fill the fuel tank and record
the initial odometer reading.
See
Refueling (page 192).
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.
Keep a record for at least one month and
record the type of driving, for example city
or highway. This provides an accurate
estimate of your vehicle ’s fuel economy
under current driving conditions. Keeping
records during summer and winter shows
how temperature impacts fuel economy. Conditions Influencing Fuel Efficiency
•
Carrying unnecessary weight in your
vehicle will reduce fuel efficiency.
• Avoid adding accessories that increase
aerodynamic drag to your vehicle such
as bug deflectors, car top carriers and
ski or bike racks.
• Remove empty roof racks and keep
windows shut at high speeds to reduce
wind resistance and fuel use.
• Check and adjust tire pressure
regularly. Under inflated tires will
increase fuel consumption.
• Sudden acceleration and braking
degrade fuel efficiency. Drive smoothly
looking as far ahead as possible and
avoid short trips when possible.
• Fuel efficiency degrades with lower
temperatures.
• Comfort Features use additional energy
and consume more fuel. Use AC and
other comfort features only when
necessary.
• Using fuel blended with alcohol may
increase fuel consumption.

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.

8.
Make sure that the oil level is between
the maximum and minimum marks. If
the oil level is at the minimum mark,
add oil immediately. See Capacities
and Specifications (page 391).
9. If the oil level is correct, replace the dipstick and make sure it is fully seated.
Note: Do not remove the dipstick when the
engine is running.
Note: If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km)
.
Adding Engine Oil WARNING: Do not remove the filler
cap when the engine is running.
Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may
not be covered by the vehicle Warranty. Only use oils certified for gasoline engines
by the American Petroleum Institute (API).
An oil with this trademark symbol
conforms to the current engine and
emission system protection standards and
fuel economy requirements of the
International Lubricants Specification
Advisory Committee (ILSAC).
To top up the engine oil level do the
following:
1. Clean the area surrounding the engine
oil filler cap before you remove it.
2. Remove the engine oil filler cap. See Under Hood Overview
(page 323).
Turn it counterclockwise and remove
it.
3. Add engine oil that meets our specifications. See
Capacities and
Specifications (page 391). You may
have to use a funnel to pour the engine
oil into the opening.
4. Recheck the oil level.
5. If the oil level is correct, replace the dipstick and make sure it is fully seated.
6. Replace the engine oil filler cap. Turn it clockwise until you feel a strong
resistance.
Note: Do not add oil further than the
maximum mark. Oil levels above the
maximum mark may cause engine damage.
Note: Make sure you install the oil filler cap
correctly.
Note: Soak up any spillage with an
absorbent cloth immediately.
