368 Wheels and Tires Low tire Possible cause Customer action required pressure warning light Flashing warning Spare tire in use Repair the damaged road wheel and light tire and reinstall it on the vehicle to restore system function. For a description on how the system functions, see When your temporary spare tire is installed in this section. Tire pressure If the tires are properly inflated and monitoring the spare tire is not in use but the system light remains on, contact your malfunction authorized dealer as soon as possible. When inflating your tires When putting air into your tires (such as at a gas station or in your garage), the tire pressure monitoring system may not respond immediately to the air added to your tires. It may take up to two minutes of driving over 20 mph (32 km/h) for the light to turn off after you have filled your tires to the recommended inflation pressure. How temperature affects your tire pressure The tire pressure monitoring system monitors tire pressure in each pneumatic tire. While driving in a normal manner, a typical passenger tire inflation pressure may increase approximately 2 to 4 psi (14 to 28 kPa) from a cold start situation. If the vehicle is stationary overnight with the outside temperature significantly lower than the daytime temperature, the tire pressure may decrease approximately 3 psi (21 kPa) for a drop of 30°F (17°C) in ambient temperature. This lower pressure value may be detected by the system as being significantly lower than the recommended inflation pressure and activate the system warning light for low tire pressure. If the low tire pressure warning light is on, visually check each tire to verify that no tire is flat. If one or more tires are flat, repair as necessary. Check air pressure in the road tires. If any tire is under-inflated, carefully drive the vehicle to the nearest location where air can be added to the tires. Inflate all the tires to the recommended inflation pressure. 2013 F-250/350/450/550 (f23) Owners Guide gf, 3rd Printing, December 2012 USA (fus)

If the tires are properly inflated and
the spare tire is not in use but the
light remains on, contact your
authorized dealer as soon as possible.
When inflating your tires
When putting air into your tires (such as at a gas station or in your
garage), the tire pressure monitoring system may not respond
immediately to the air added to your tires.
It may take up to two minutes of driving over 20 mph (32 km/h) for the
light to turn off after you have filled your tires to the recommended
inflation pressure.
How temperature affects your tire pressure
The tire pressure monitoring system monitors tire pressure in each
pneumatic tire. While driving in a normal manner, a typical passenger tire
inflation pressure may increase approximately 2 to 4 psi (14 to 28 kPa)
from a cold start situation. If the vehicle is stationary overnight with the
outside temperature significantly lower than the daytime temperature, the
tire pressure may decrease approximately 3 psi (21 kPa) for a drop of 30°F
(17°C) in ambient temperature. This lower pressure value may be detected
by the system as being significantly lower than the recommended inflation
pressure and activate the system warning light for low tire pressure. If the
low tire pressure warning light is on, visually check each tire to verify that
no tire is flat. If one or more tires are flat, repair as necessary. Check air
pressure in the road tires. If any tire is under-inflated, carefully drive the
vehicle to the nearest location where air can be added to the tires. Inflate
all the tires to the recommended inflation pressure.
