•
Check the extension cord for heat
anywhere when the system has been
operating for approximately 30
minutes.
• Unplug and properly stow the system
before starting and driving your vehicle.
The protective cover seals the
terminals of the engine block heater
cord plug when not in use.
• Check the engine block heater system
for proper operation before winter.
HOW DOES THE ENGINE BLOCK
HEATER WORK
The engine block heater warms the engine
coolant. This allows the climate control
system to quickly respond. The equipment
includes a heater element installed in the
engine block and a wire harness. You can
connect the system to a grounded
220-240 volt AC electrical source.
Note: The engine block heater is most
effective when outdoor temperatures are
below 0°F (-18°C).
USING THE ENGINE BLOCK
HEATER
Make sure the receptacle terminals are
clean and dry prior to use. Clean them with
a dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours
of energy per hour of use. The system does
not have a thermostat. It achieves
maximum temperature after
approximately three hours of operation.
Using the engine block heater longer than
three hours does not improve system
performance and unnecessarily uses
electricity. STOPPING THE ENGINE

HYBRID ELECTRIC VEHICLE
INFORMATION – FREQUENTLY
ASKED QUESTIONS
How long is the high voltage battery
system designed to last?
The high voltage battery system is
designed to last the life of your vehicle.
Does the high voltage battery require
maintenance? The high voltage battery does not
require maintenance.
What should I do if the vehicle runs out
of fuel and the high voltage battery is
out of charge? Refuel and start your vehicle normally.
The engine will recharge the high
voltage battery.
Why does the engine sometimes start
at key-on? The vehicle's computer will determine
if an engine start is required at key-on.
It starts the engine when necessary for
cabin heating, windshield defrost, or if
the outside temperature is low.
Can I put E15 or E85 in my vehicle, and
how will it affect my fuel economy? Your hybrid vehicle can use E15 (15%
ethanol, 85% gasoline) fuel, but you
may notice slightly reduced fuel
economy because ethanol contains
less energy per gallon than gasoline.
Your hybrid vehicle is not designed to
use E85 (85% ethanol). Why does it take a long time before the
engine shuts down?
There are several reasons the engine
stays on for an extended amount of
time when you first start it. One
common reason is to make sure that
the emissions components are warm
enough to minimize tailpipe emission.
As the climate gets cooler, the
engine-on time is extended.
Why does my engine stay on when it is
extremely cold outside? In order to make sure that the climate
control system can begin heating the
cabin or defrosting the windshield as
soon as a driver requests it, the engine
coolant temperature has to be kept
sufficiently hot. Keeping the engine on
is required to maintain the correct
coolant temperature.
ECO IDLE
WHAT IS ECO IDLE
Eco idle reduces fuel consumption when
your vehicle is in park (P) and idling for long
periods of time. Eco idle more efficiently
extends the use of features that are
powered by the high voltage battery when
your vehicle is stationary.
HOW DOES ECO IDLE WORK
Eco idle increases the engine idle speed
above normal for a short period of time to
efficiently charge the high voltage battery.
Note: Engine sound and vibration could be
more noticeable.
SWITCHING ECO IDLE ON AND OFF
To switch eco idle on and off use the
touchscreen:

ENGINE OIL CAPACITY AND
SPECIFICATION
For filling information, please refer to the
Capacities and Specifications section of
your owner's manual. See
Engine Oil
Capacity and Specification (page 489). CHECKING THE COOLANT
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 642).
Note: Make sure that the coolant level is
between the minimum and maximum marks
on the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between
-29°F (-34°C) and -35°F
(-37°C). Coolant concentration should be
checked using a refractometer. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.
Adding Coolant WARNING:
Keep your hands and
clothing clear of the cooling fan. 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 add engine
coolant when the engine is on or the
cooling system is hot. Failure to follow
this instruction could result in personal
injury.

2022 F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202109, First-Printing Maintenance

WARNING: Do not add coolant
further than the MAX mark. 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:
Do not allow the fluid
to touch your skin or eyes. If this
happens, rinse the affected areas
immediately with plenty of water and
contact your physician.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
Note: Automotive fluids are not
interchangeable.
It is very important to use prediluted
coolant approved to the correct
specification in order to avoid plugging the
small passageways in the engine cooling
system. See
Capacities and
Specifications (page 558). Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine
or cooling system components and could
void the vehicle Warranty.
Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with deionized or
distilled water. See
Capacities and
Specifications (page 558). Using water that
has not been deionized may contribute to
deposit formation, corrosion and plugging
of the small cooling system passageways.
To top up the coolant level do the
following: 1. Unscrew the cap slowly. Any pressure
escapes as you unscrew the cap.
2. Add enough prediluted coolant to reach the correct level.
Note: We do not recommend the use of
recycled coolant.
3. Replace the coolant reservoir cap. Turn
the cap clockwise until it contacts the
hard stop.
4. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If necessary, repeat step
2.
If you have to add more than
1.1 qt (1 L) of
engine coolant per month, have your
vehicle checked as soon as possible.
Operating an engine with a low level of
coolant can result in engine overheating
and possible engine damage.
In case of emergency, you can add a large
amount of water without engine coolant
in order to reach a vehicle service location.
Service your vehicle as soon as possible.
Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute, as they can cause engine
damage from overheating or freezing:
• Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of
the coolant.
