2021 FORD F-350 warning light

The trailer tire pressure monitoring system
can be reset through the menu in the
information display. See General
Information (page 110). Performing the
trailer setup process also resets the trailer
tire pressure monitoring system.
CHANGING A ROAD WHEEL WARNING:
If the tire pressure
monitor sensor becomes damaged it
may not function.
Note: If your vehicle is equipped with the
tire pressure monitoring system, the
indicator light illuminates when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.
Note: You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
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.
If your vehicle is equipped with the tire
pressure monitoring system, have a flat
serviced by an authorized dealer in order
to prevent damage to the system sensors.
See
Tire Pressure Monitoring System
(page 421). Replace the spare tire with a
road tire as soon as possible. During
repairing or replacing of the flat tire, have
the authorized dealer inspect the system
sensor for damage. 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, then it is intended for temporary use
only. This means that if you need to use it,
you should 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 that were originally provided
by Ford. If the dissimilar spare tire or wheel
is damaged, it should be replaced rather
than repaired.
A dissimilar spare wheel and tire assembly
is defined 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.
When driving with the full-size dissimilar
spare wheel and tire assembly, 4WD
functionality may be limited. You may
experience the following:
• Additional noise from the transfer case
or other drive components.
• Difficulty shifting out of a mechanically
locked 4WD mode.
