2020 FORD EXPLORER check engine light

•
Carry unnecessary weight
(approximately 1 mpg [0.4 km/L] is
lost for every 395 lb (180 kg) of weight
carried).
• Driving with the wheels out of
alignment.
Conditions
• Heavily loading a vehicle or towing a
trailer may reduce fuel economy at any
speed.
• Adding certain accessories to your
vehicle (for example bug deflectors,
rollbars, light bars, running boards, ski
racks or luggage racks) may reduce
fuel economy.
• To maximize the fuel economy, drive
with the tonneau cover installed (if
equipped).
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures during the first
5–10 mi
(12 –16 km) of driving.
• Driving on flat terrain offers improved
fuel economy as compared to driving
on hilly terrain.
• Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.
• Four-wheel-drive operation (if
equipped) is less fuel efficient than
two-wheel-drive operation.
• Close the windows for high-speed
driving.
COLD WEATHER
PRECAUTIONS
The functional operation of some
components and systems can be affected
at temperatures below
-13°F (-25°C). BREAKING-IN
You need to break in new tires for
approximately
300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics.
Avoid driving too fast during the first
1,000 mi (1,600 km)
. Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
Do not tow during the first
1,000 mi
(1,600 km).
DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note: Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the front
rocker area of your vehicle. 297

housing and cover to make sure no dirt
gets in the engine and that you have a
good seal.
7. Install a new air filter element. Be careful not to crimp the filter element
edges between the air filter housing
and cover. This could cause filter
damage and allow unfiltered air to
enter the engine if it is not properly
seated. 8. Install the air filter housing cover.
9. Engage the clips to secure the air filter
housing cover to the air filter housing.
10. Reconnect the boot to the air filter housing cover and torque to 3.69 lb.ft
(5 Nm).
ENGINE COOLANT CHECK WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury. WARNING:
Do not put coolant in
the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield. WARNING:
To reduce the risk of
personal injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling system
is under pressure. Steam and hot liquid
can come out forcefully when you loosen
the cap slightly. WARNING:
Do not add coolant
further than the MAX mark.
When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 487).
Note: Make sure that the coolant level is
between the
MIN and MAX marks on the
coolant reservoir.

Manual or your local maintenance guide.
POWER STEERING FLUID
CHECK
Your vehicle is equipped with an electric
power steering (EPS) system. There is no
fluid reservoir to check or fill.
CHANGING THE 12V BATTERY
WARNING: Batteries normally
produce explosive gases which can
cause personal injury. Therefore, do not
allow flames, sparks or lighted
substances to come near the battery.
When working near the battery, always
shield your face and protect your eyes.
Always provide correct ventilation. WARNING:
When lifting a
plastic-cased battery, excessive pressure
on the end walls could cause acid to flow
through the vent caps, resulting in
personal injury and damage to the
vehicle or battery. Lift the battery with a
battery carrier or with your hands on
opposite corners. WARNING:
Keep batteries out of
reach of children. Batteries contain
sulfuric acid. Avoid contact with skin,
eyes or clothing. Shield your eyes when
working near the battery to protect
against possible splashing of acid
solution. In case of acid contact with skin
or eyes, flush immediately with water for
a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed,
call a physician immediately. WARNING:
Battery posts,
terminals and related accessories
contain lead and lead compounds,
chemicals known to the State of
California to cause cancer and
reproductive harm. Wash your hands
after handling
. WARNING:
This vehicle may have
more than one battery. Removing the
battery cables from only one battery
does not disconnect your vehicle
electrical system. Make sure you
disconnect the battery cables from all
batteries when disconnecting power.
Failure to do so may cause serious
personal injury or property damage. WARNING:
For vehicles with
Auto-Start-Stop the battery requirement
is different. You must replace the battery
with one of exactly the same
specification.
The battery is in the engine compartment.
See
Under Hood Overview (page 324).
Your vehicle has a maintenance-free
battery. It does not require additional
water during service.
If the vehicle battery has a cover and vent
hose, make sure you correctly install it after
cleaning or replacing the battery.
For longer, trouble-free operation, keep the
top of the battery clean and dry and the
battery cables tightly fastened to the
battery terminals. If any corrosion is
present on the battery or terminals, remove
the cables from the terminals and clean
with a wire brush. You can neutralize the
acid with a solution of baking soda and
water.
We recommend that you disconnect the
negative battery cable terminal from the
battery if you plan to store your vehicle for
an extended period.

GENERAL INFORMATION
The recommended tire inflation pressures
are found on the Tire Label which is
located on the B-pillar or the edge of the
driver door. This information can also be
found on the Safety Compliance
Certification Label, affixed to either the
door hinge pillar, door-latch post, or the
door edge that meets the door-latch post,
next to the driver
’s seating position.
We strongly recommend maintaining these
tire pressures at all times. Failure to follow
the tire pressure recommendations can
cause uneven treadwear patterns, reduced
fuel economy, and adversely affect the
way your vehicle handles.
Note: Check and set the tire pressure at the
ambient temperature in which you are
intending to drive your vehicle and when the
tires are cold.
Note: Check your tire pressures at least
once per month.
If your vehicle has a spare tire, set the
pressure to the highest value given for your
vehicle and tire size combination.
Use only approved wheels and tire sizes;
using other sizes could damage your
vehicle.
If you change the diameter of the factory
installed tires, the speedometer could
display the incorrect speed. This could
effect the functionality of the 4WD system
(if equipped). Take your vehicle to an
authorized dealer and have the engine
management system reprogrammed.
If you intend to change the size of the
factory installed tires, check the suitability
with an authorized dealer.
Additional information related to the
functionality and maintenance of your tires
can be found in the Wheels and Tire
section. See Tire Care (page 355). Self-Sealing Tires
(If Equipped)
Self-Sealing tires are a special type of tire
that have a material on the inside of the
tire that can seal punctures up to
0.2 in
(6 mm) in diameter in the tread area. This
material does not protect from damage or
punctures in the sidewall of the tire.
Self-sealing tires can be identified by the
tire manufacturer with a special mark.
If your TPMS warning light comes on,
inspect your tires for damage and re-inflate
your tires to the pressure indicated on the
tire placard. See
Tire Pressure
Monitoring System (page 370). If your
tires are damaged or continue to lose air,
take your vehicle to the nearest authorized
dealer to have your tires inspected and
repaired/replaced as necessary.
Note: Replace self-sealing tires with
self-sealing tires to maintain the
functionality provided.
Note: Do not drive on a deflated
self-sealing tire. This damages the tire
beyond repair.
Notice to utility vehicle and truck
owners WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death. WARNING:
In a rollover crash, an
unbelted person is significantly more
likely to die than a person wearing a
seatbelt.
