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:

WARNING: Always re-inflate tires
to recommended tire pressures before
the vehicle is operated on-road. The
recommended pressure is located on the
tire label or safety certification label,
located on the B-pillar, inside the driver's
door.
Driving off-road places more stress on your
vehicle than most on-road driving. After
driving off-road check for damage to your
vehicle and, if necessary, have your vehicle
fixed as soon as possible.
Inspect the underbody of your vehicle by
checking tires, body structure, steering,
suspension, and exhaust system for
damage.
Check the radiator for mud and debris and
clean as needed.
Remove accumulations of plants or brush.
These things could be a fire hazard or hide
damage to the fuel lines, brake hoses, and
propeller shafts.
After extended operation in mud, sand,
water, or similar dirty conditions, inspect
the underbody and clean your vehicle as
soon as possible.
If you experience unusual vibration after
driving in mud, slush or similar conditions,
check the wheels for impacted material.
Impacted material can cause vibrations
while driving and wheel imbalance.
Remove the material to resolve the
problem.
COLD WEATHER
PRECAUTIONS
The functional operation of some
components and systems can be affected
at temperatures below approximately
-13°F (-25°C)
. 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 your vehicle slides while
cornering, steer in the direction of the
slide until you regain control of your
vehicle.
On ice and snow, you should drive more
slowly than usual. Your vehicle has a four
wheel anti-lock brake system, do not pump
the brake pedal.
See Anti-Lock Braking
System Limitations (page 308).
BREAKING-IN
Your vehicle requires a break-in period. For
the first 1,000 mi (1,600 km), avoid driving
at high speeds, heavy braking, aggressive
shifting or using your vehicle to tow. During
this time, your vehicle may exhibit some
unusual driving characteristics.
DRIVING ECONOMICALLY
The following helps to improve fuel
consumption:
• There is no need to wait for your engine
to warm up. The vehicle is ready to
drive immediately after starting.
• Your fuel consumption should improve
throughout your hybrid's break-in
period.
• Accelerate and slow down in a smooth,
moderate fashion.
476
F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Driving Hints

•
Moderate braking is particularly
important since it allows you to
maximize the energy captured by the
regenerative braking system.
• Drive at steady speeds without
stopping.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Driving on flat terrain.
• Drive at reasonable speeds and
observe posted speed limits.
• Shut all windows when driving at high
speeds.
• Combine errands and minimize
stop-and-go driving.
• Drive with the tonneau cover installed
if your vehicle comes with one.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Follow the recommended maintenance
schedule and carry out the
recommended checks.
• Perform all scheduled maintenance.
Note: Having your engine running is not
always an indication of inefficiency. In some
cases, it is actually more efficient than
driving in electric mode.
Avoid these actions; they reduce your fuel
consumption:
• Revving the engine.
• Aggressive driving increases the
amount of energy required to move
your vehicle.
• Driving in lower temperatures during
the first 5–10 mi (12 –16 km) of driving.
• Idle for periods longer than one minute.
• Use the air conditioner or front
defroster. •
Adding certain accessories to your
vehicle like bug deflectors, rollbars,
light bars, running boards, ski racks or
luggage racks.
• Use the speed control in hilly terrain.
• Using fuel blended with alcohol.
• Drive a heavily loaded vehicle or tow a
trailer.
• Driving with the wheels out of
alignment.
DRIVING IN SPECIAL
CONDITIONS
EMERGENCY MANEUVERS
In an unavoidable emergency where you
must make a sudden sharp maneuver, turn
the steering wheel only as rapidly and as
far as required to avoid the emergency.
Apply smooth pressure to the accelerator
pedal or brake pedal as needed. Avoid
abrupt steering, acceleration and braking
changes. Abrupt changes could increase
the risk of vehicle roll over, loss of vehicle
control and personal injury. If possible, use
any available road surfaces to bring your
vehicle under control.
FLOOR MATS WARNING:
Use a floor mat
designed to fit the footwell of your
vehicle that does not obstruct the pedal
area. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Pedals that cannot
move freely can cause loss of vehicle
control and increase the risk of serious
personal injury.

GENERAL MAINTENANCE
INFORMATION
Why Maintain Your Vehicle?
Carefully following the maintenance
schedule helps protect against major repair
expenses resulting from neglect or
inadequate maintenance and may help to
increase the value of your vehicle when
you sell or trade it. Keep all receipts for
completed maintenance with your vehicle.
It is important that you have your vehicle
serviced at the proper times. These
intervals serve two purposes: first is to
maintain the reliability of your vehicle and
the second is to keep the cost of owning
your vehicle down.
It is your responsibility to have all
scheduled maintenance performed and to
make sure that the materials used meet
the specifications identified in this owner's
manual. See Capacities and
Specifications (page 574).
Failure to perform scheduled maintenance
and regularly inspect your vehicle may
result in vehicle damage not covered by
the vehicle Warranty.
Why Maintain Your Vehicle at Your
Dealership?
Our Genuine Replacement Parts
Dealerships stock our parts and our
authorized branded re-manufactured
replacement parts. These parts meet or
exceed our specifications. Parts installed
at your dealership carry a nationwide
24-month or unlimited mile (kilometer)
parts and labor limited warranty.
If you do not use our authorized parts they
may not meet our specifications and could
affect emissions compliance. Protecting Your Investment
Maintenance is an investment that pays
dividends in the form of improved
reliability, durability and resale value. To
maintain the proper performance of your
vehicle and its emission control systems,
make sure you have scheduled
maintenance performed at the designated
intervals.
Your vehicle comes with the Intelligent
Oil-Life Monitor system, a message
appears in the information display at the
proper oil change interval. This interval
may be up to one year or
10,000 mi
(16,000 km), hybrid vehicles could exceed
10,000 mi (16,000 km).
When the oil change message appears in
the information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or
500 mi
(800 km) of the message appearing. Make
sure to reset the Intelligent Oil-Life Monitor
after each oil change. See
Resetting the
Engine Oil Change Reminder (page 511).
If your information display resets
prematurely or becomes inoperative, you
should perform the oil change interval at
six months or
5,000 mi (8,000 km) from
your last oil change. Never exceed one year
or
10,000 mi (16,000 km) between oil
change intervals.
You can drive high performance vehicles
in such a way that may lead to higher oil
consumption including extended time at
high engine speeds, high loads, engine
braking, hard cornering maneuvers, track
and off-road usage. Under these
conditions, oil consumption of
approximately 1 quart per 500 miles (1 liter
per 800 km) is possible. Check the engine
oil level at every refueling and adjust to
maintain proper levels to avoid engine
damage.

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.
• Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for
climactic conditions.
