engine FORD F-150 2021 Owners Manual

When operating your vehicle with a
snowplow:
•
Do not exceed 45 mph (72 km/h).
• Your engine could run at a higher
temperature than normal.
•If you are driving more than
15 mi
(24 km) at temperatures above
freezing, angle the plow blade
either full left or full right to provide
maximum airflow to the radiator.
• If you are driving less than
15 mi
(24 km) at speeds up to 45 mph
(72 km/h) in cold weather, you do
not need to worry about blade
position to provide maximum
airflow.
• Shift to 4L when plowing in small areas
at speeds below
5 mph (8 km/h).
• Shift to
4H when plowing larger areas
or light snow at higher speeds above
5 mph (8 km/h)
. Do not exceed
15 mph (24 km/h).
• Do not shift the transmission from a
forward gear to reverse (R) until the
engine is at idle and the wheels have
stopped.
Note: Careless or high-speed driving when
snowplowing, which results in significant
vehicle decelerations, can deploy the airbag.
Such driving also increases the risk of
accidents.
Note: Drive your vehicle at least
500 mi
(800 km) before using your vehicle for
snowplowing.
Note: Follow the severe duty schedule for
engine oil and transmission fluid change
intervals. See
Special Operating
Conditions Scheduled Maintenance (page
675
). SNOWPLOW MODE
WHAT IS SNOWPLOW MODE
Snowplow mode reduces vehicle electrical
load to allow the electrical system to have
sufficient power to support residential
snowplow use.
SWITCHING SNOWPLOW MODE
ON AND OFF
Vehicles receive a physical button in the
instrument panel or an option in the SYNC
menu to enable snowplow mode.
Snowplow mode does not remember the
setting when you switch your vehicle off.
You must re-enable the mode every time
you wish to use it.
The following features turn off and are
disabled in snowplow mode and cannot
be turned back on until snowplow mode
is switched off:
•
120 V
inverter.
• Fog lamps.
• Heated and cooled front seats.
The body module also activates the
snowplow relay that provides power to
aftermarket snowplow controls.
Note: The electrical system supports the
addition of a residential snowplow of up to
60 A
continuous, and snowplow lights of
up to 20 A continuous using snowplow
mode. The system does not support
snowplow usage with additional electrical
aftermarket accessories.
Push Button
(If Equipped)
Press the snowplow button on the
instrument panel to switch on snowplow
mode. The snowplow button illuminates
and a message displays.

Post-Incident
1. Do not store a severely damaged
vehicle with a lithium-ion battery inside
a structure or within 50 ft (15 m) of any
structure or vehicle.
2. Make sure that passenger and luggage
compartments remain ventilated.

JUMP STARTING THE VEHICLE
JUMP STARTING PRECAUTIONS 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:
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:
Use only adequately
sized cables with insulated clamps. WARNING:
Make sure that the
cables are clear of any moving parts and
fuel delivery system parts. WARNING: Connect batteries with
only the same nominal voltage. WARNING: If the engine is running
while the hood is open, stay clear of
moving engine components. Failure to
follow this warning could result in serious
personal injury or death.
Do not attempt to push-start an automatic
transmission vehicle. This could cause
transmission damage.
Do not disconnect the battery of the
disabled vehicle. This could damage your
vehicle's electrical system.
PREPARING THE VEHICLE
Use only a 12 volt supply to start your
vehicle.
Park the booster vehicle close to the hood
of the disabled vehicle, making sure the
two vehicles do not touch.

JUMP STARTING THE VEHICLE
Connecting the Jumper Cables
WARNING: Do not connect the
negative jumper cable to any other part
of your vehicle. Use the ground point.
Note: If you are using a jump pack or
booster box, follow the manufacturer's
instructions. 1. Pull the red rubber boot backward.
Connect the positive (+) jumper cable
to the positive (+) terminal of the
discharged battery.
2. Connect the other end of the positive (+) jumper cable to the positive (+)

4. Make the final connection of the negative (-) jumper cable to an
exposed metal part of the disabled
vehicle's engine, as shown in the
following illustration, away from the
battery and fuel injection system, or
connect the negative (-) jumper cable
to a ground connection point if
available.
Note: Do not use the hood latch as a
negative (-) connection point. This could
cause springs in the latch to burn and
prevent the hood from operating correctly. Starting the Engine

Start the engine of the booster vehicle
and moderately rev the engine, or
gently press the accelerator to keep
the engine speed between 2000 and
3000 RPM, as shown in your
