2021 FORD F-550 heating

Touch the button to switch the
heated steering wheel on and
off.
Note: You can use the heated steering
wheel only when the engine is running.
Note: The system uses a sensor and is
designed to control the temperature of the
steering wheel and to prevent it from
overheating.
Note: In warm temperatures, the steering
wheel quickly reaches its maximum
temperature and the system reduces the
current to the heating element. This could
cause you to think that the system has
stopped working but it has not. This is
normal.

Press and hold the function button you
want to program for 2 seconds, then
release. Repeat this step. Depending
on your brand of garage door opener,
you may need to repeat this sequence
a third time.
Gate Operator / Canadian
Programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission –
which may not be long enough for
HomeLink to pick up the signal during
programming. Similar to this Canadian law,
some U.S. gate operators are designed to
“time-out” in the same manner.
Note: If programming a garage door opener
or gate operator, it is advised to unplug the
device during the “cycling” process to
prevent possible overheating.
1. Press and release, every two seconds,
your hand-held transmitter until the
HomeLink indicator light changes to a
rapidly blinking or continuously on light.
2. Release the hand-held transmitter button.
3. Continue programing HomeLink. See In-Vehicle Programming, Step 4.
Erasing the Function Button Codes
Note: You cannot erase individual buttons. 1. Press and hold the outer two function
buttons simultaneously for
approximately 10 seconds until the
indicator light above the buttons
flashes rapidly.
2. When the indicator light flashes, release the buttons. You erased the
codes for all buttons.
Reprogramming a Single Button
To program a device to a previously trained
button, follow these steps:
1. Press and hold the desired button. Do NOT release the button.
2. The indicator light begins to flash after
20 seconds. Without releasing the
button, follow Step 1 in the
Programming section.

Right Fuel: Vehicles Operated
Where Ultra Low Sulfur Diesel Fuel
Is Required (United
States/Canada/Puerto Rico/U.S.
Virgin Islands And Other Locales)
Note:
Your warranty will not cover damage
caused by using an improper type of fuel or
fuel additive.
Note: Do not blend used engine oil with
diesel fuel under any circumstances.
Blending used oil with the fuel will
significantly increase your vehicle ’s exhaust
emissions and reduce engine life due to
increased internal wear.
We recommend Top Tier diesel fuel where
available to help minimize engine deposits
and maintain optimal vehicle and engine
performance. For additional information,
refer to www.toptiergas.com.
You should use Ultra-Low Sulfur Diesel
fuel (also known as ULSD) designated as
number 1-D or 2-D with a maximum of
15-ppm sulfur in your diesel vehicle. You
may operate your vehicle on diesel fuels
containing up to 20% biodiesel, also
known as B20. These fuels should meet
the ASTM D975 diesel or the ASTM D7467
B6-B20 biodiesel industry specifications.
Outside of North America, use fuels
meeting EN590 or equivalent local market
standard. Using low sulfur diesel fuel
(16-500 ppm) or high sulfur
diesel fuel (greater than 500
ppm) in your diesel engine will cause
certain emission components to
malfunction which may also cause the
service engine soon light to illuminate
indicating an emissions-related concern. Diesel fuel is adjusted seasonally for cold
temperature. For best results at
temperatures below 19°F (-7°C), we
recommended using a diesel fuel which
has been seasonally adjusted for the
ambient conditions.
Fuel Requirements - Choosing The
Right Fuel: Vehicles Operated
Where Ultra Low Sulfur Diesel Fuel
Is Not Required
For the engine to operate reliably on
low-sulfur or high-sulfur diesel fuel, the
engine must be a factory built high-sulfur
engine (available as a dealer order option
for select markets) or an ultra low sulfur
diesel fuel configured engine that has been
retrofitted for high-sulfur diesel fuel using
Ford Motor Company dealer service parts.
Failure to use retrofit components other
than those available through your
authorized dealer will result in coolant
system damage, engine overheating,
selective catalyst reduction system or
diesel particulate filter damage and
possible base engine damage.
Use only a diesel engine configured for use
with high sulfur diesel fuel in markets with
diesel fuel that has sulfur content greater
than 15 ppm. Using low sulfur diesel fuel
(16–500 ppm) or high sulfur diesel fuel
(greater than 500 ppm) in a diesel engine
designed to use only Ultra Low Sulfur
Diesel fuel may result in damage to engine
emission control devices and the
aftertreatment system, potentially
rendering the vehicle inoperable.
Vehicles with engines configured for use
with high sulfur diesel fuel are only
available for sale in countries where ultra
low sulfur diesel fuel is generally not
available or mandated by the government.

diesel fuel market that are subsequently
