2021 FORD F-150 service indicator

Note:
During parking maneuvers, the
adaptive steering system balances the driver
workload for various steering wheel inputs
and vehicle loading conditions. Under
extreme operating conditions the system
locking device could engage. This strategy
prevents overheating and permanent
damage to the adaptive steering system.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
Adaptive Learning
Adaptive learning helps correct road
irregularities and improves overall handling
and steering. It communicates with the
brake system to help operate advanced
stability control and crash avoidance
systems. Additionally, whenever you
disconnect the battery or install a new
battery, you must drive your vehicle a short
distance before the system relearns the
strategy and reactivates all systems. STEERING –

DRAINING THE FUEL FILTER
WATER TRAP - DIESEL WARNING: Do not drain the
water-in-fuel separator while the engine
is running. Failure to follow this warning
may result in fire, serious injury, death or
property damage. WARNING:
Do not dispose of fuel
in the household refuse or the public
sewage system. Use an authorized waste
disposal facility.
Your vehicle's fuel system has a fuel filter
and water separator to remove water from
the fuel.
If the water in fuel indicator illuminates
when the engine is running, stop your
vehicle as soon as safely possible, shut off
the engine, then drain the fuel and water
separator.
Note: Allowing water to stay in the fuel
system after the water in fuel indicator
illuminates could result in extensive damage
or failure of the fuel injection system. The fuel water trap is above the frame rail
under the driver side of the vehicle.
Make sure the ignition is off before
performing the following steps.
Front of Vehicle.
A
1. Loosen the drain plug approximately one and a half turns.
2. Allow the water to drain.
3. Tighten the drain plug until you feel a strong resistance.
4. Switch the ignition on for 30 seconds, then switch the ignition off. Repeat
twice.

Note:
If the system does not enter
reset mode, try again starting at
Step 2. If after repeated attempts
to enter the reset mode, the horn
does not sound, the system
indicator does not flash and no
message shows in the information
display, contact your authorized
dealer.
5. Remove the valve cap from the
valve stem on the left front tire.
Decrease the air pressure until
the horn sounds.
Note: The single horn tone
confirms that the sensor
identification code has been
learned by the module for this
position. If the horn sounds twice,
the reset procedure was
unsuccessful, and you must repeat
it.
6. Remove the valve cap from the
valve stem on the right front
tire. Decrease the air pressure
until the horn sounds.
7. Repeat the previous step on the right rear tire and then on
the left rear tire.
8. Switch the ignition off.
Note: If the horn sounds twice
again after switching the ignition
off, and repeating the procedure,
contact your authorized dealer and
have your vehicle checked as soon
as possible.
9. Set all four tires to the
recommended air pressure as
indicated on the Safety
Compliance Certification Label. Trailer Tire Pressure
Monitoring System (If Equipped)
Note: Additional equipment may
be required for your vehicle to
support trailer tire pressure and
temperature monitoring. See your
authorized dealer for more
information.
Note: The trailer tire pressure
monitoring system is not a
substitute for proper tire
maintenance. It is your
responsibility to maintain correct
tire pressures at all times.
Note: If a trailer tire is repaired,
replaced or broken down for
service, the screw and valve on the
trailer tire pressure sensor should
be replaced. See your authorized
dealer for details. The trailer tire pressure monitoring
system is an added safety feature
that allows you to view your trailer
tire pressures and temperatures
through the information display.

CHANGING A FLAT TIRE
If you get a flat tire when driving, do not
apply the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe
place on the side of the road.
Have a flat serviced by an authorized
dealer to prevent damage to the system
sensors. See Tire Pressure Monitoring
System Precautions (page 560). Replace
the spare tire with a road tire as soon as
possible. When repairing or replacing the
flat tire, have the authorized dealer inspect
the system sensor for damage.
Note: The use of tire sealant could damage
your tire pressure monitoring system. Only
use in roadside emergencies.
Note: The tire pressure monitoring system
indicator light illuminates when the spare
tire is in use. To restore the full function of
the monitoring system, you must mount all
road wheels that come with tire pressure
monitoring sensors on this vehicle.
Dissimilar Spare Wheel and Tire
Assembly Information WARNING:
Failure to follow these
guidelines could result in an increased
risk of loss of vehicle control, injury or
death.
If you have a dissimilar spare wheel and
tire, the intent of the spare wheel is for
temporary use only. This means that if you
need to use it, replace it as soon as
possible with a road wheel and tire
assembly that is the same size and type
as the road tires and wheels originally
provided by Ford. We define a dissimilar spare wheel and tire
assembly as a spare wheel and tire
assembly that is different in brand, size or
appearance from the road tires and
wheels.
Full-size dissimilar spare
When driving with the full-size dissimilar
spare wheel and tire assembly, do not:
•
Exceed
70 mph (113 km/h).
• Use more than one dissimilar spare
wheel and tire assembly at a time.
• Use snow chains on the end of the
vehicle with the dissimilar spare wheel
and tire assembly.
Engage any four-wheel drive mode. See
Four-Wheel Drive Limitations (page 292).
The usage of a full-size dissimilar spare
wheel and tire assembly can lead to
impairment of the following:
• Handling, stability and braking
performance.
• Comfort and noise.
• Ground clearance and parking at curbs.
• Winter weather driving capability.
• Wet weather driving capability.
• Four-wheel drive capability.
When driving with the full-size dissimilar
spare wheel and tire assembly, give
additional caution to:
• Towing a trailer.
• Driving vehicles that come with a
camper body.
• Driving vehicles with a load on the
cargo rack.
Drive cautiously when using a full-size
dissimilar spare wheel and tire assembly
and seek service as soon as possible.
