Tire pressure monitoring If the tires are correctly inflated and the system malfunction spare tire is not in use but the light remains on, have your vehicle checked by an authorized dealer as soon as possible. When Inflating the Tires When inflating the tires (for example; at a gas station), the system may not respond immediately to the air added to the 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 the Tire Pressures While driving in a normal manner, tire pressures may increase up to 4 psi (0.3 bar) from a cold start situation. If the vehicle is stationary overnight and the temperature significantly lower than the daytime temperature, tire pressures may decrease up to 3 psi (0.2 bar) for a drop of 30°F (17°C) in ambient temperature. This lower pressure value will be detected by the system as being significantly lower than the correct inflation pressure and the warning light will illuminate. If the warning light is on: • Check each tire to verify that none are flat. • If one or more tires are flat, repair as necessary. • Check the tire pressures and Inflate all the tires to the correct pressure. Tire Pressure Monitoring System Reset Procedure Note: The system reset procedure needs to be carried out after each tire replacement. 254 Transit (TTH) Canada/United States of America, enUSA, Edition date: 03/2014, Third Printing
