Tire Pressure Monitoring System Reset Procedure
WARNING: To determine the required pressure(s) for your
vehicle, see the Safety Compliance Certification Label (affixed to
either the door hinge pillar, door-latch post, or the door edge that
meets the door-latch post, next to the driver’s seating position), or Tire
Label located on the B-Pillar or the edge of the driver’s door. See Load
Carrying for more information.
Note: The tire pressure monitoring system reset procedure needs to be
performed after each tire rotation on vehicles that require different
recommended tire pressures in the front tires as compared to the rear
tires.
Overview
To provide the vehicle’s load carrying capability, some vehicles require
different recommended tire pressures in the front tires as compared to
the rear tires. The tire pressure monitoring system equipped on these
vehicles is designed to illuminate the low tire pressure warning light at
two different pressures; one for the front tires and one for the rear tires.
Since tires need to be rotated to provide consistent performance and
maximum tire life, the tire pressure monitoring system needs to know
when the tires are rotated to determine which set of tires are on the
front and which are on the rear. With this information, the system can
detect and properly warn of low tire pressures.
System reset tips:
• To reduce the chances of interference from another vehicle, the
system reset procedure should be performed at least three feet (one
meter) away from another Ford Motor Company vehicle undergoing
the system reset procedure at the same time.
• Do not wait more than two minutes between resetting each tire sensor
or the system will time-out and the entire procedure will have to be
repeated on all four wheels.
• A double horn chirp indicates the need to repeat the procedure.
