Customer Action Required
Check tire pressure to ensure proper inflation. Ford recommends a digital or dial-type
tire pressure gauge for increased accuracy.
• Afterinflatingcoldtirestomanufacturer’srecommendedpressureasshownon
the tire label, the vehicle must be driven for at least 2 minutes at over 20 mph to
turn the light off and reset the system
• Ifthelightremainsonevenafterthesestepshavebeentaken,have the system
inspected by the dealership Service Department
NOTE: If the outside overnight temperature is significantly lower than the daytime
temperature, tire pressure will decrease 1 psi for every 10 degrees F drop in temperature.
This may cause the TPMS warning to illuminate. If all tires appear to be inflated,
customers should manually check the pressure and inflate all the tires to the recommended
cold pressure.
• Driving on the spare tire may activate the TPMS warning light, causing it to flash for
75 seconds followed by a solid light. Repair the damaged road wheel and remount
it on the vehicle. Reset the TPMS by driving at over 20 mph for at least 2 minutes
• Ifthetiresareinflatedtothemanufacturer’srecommendedpressureandthespare
tire is not in use, have the system inspected by the Service Department
