If a Tire Goes Flat It is unusual for a tire to "blow out" while you are driving, especially if you maintain your tires properly. If air goes out of a tire, it is much more likely to leak out slowly. See Tires on page 413 for additional information. Your vehicle, when new, had run-flat tires. This type of tire can operate effectively with no air pressure, so you will not need to stop on the side of the road to change a flat tire. You can just keep on driving. The shorter the distance you drive and the slower the speed, the greater the chance that the run-flat tire will not have to be replaced. Run-flat tires perform so well without any air that a Tire Pressure Monitor (TPM) is used to alert you if a tire has lost pressure. See Run-Flat Tires on page 420 and Tire Pressure Monitor System on page 423. {CAUTION: When the TIRE FLAT MAX SPD 55, REDUCED HNDLG message is displayed on the Driver Information Center, your vehicle's handling capabilities will be reduced during severe maneuvers. If you drive too fast, you could lose control of your vehicle. You or others could be injured. Don't drive over 55 mph (90 km/h) when the TIRE FLAT MAX SPD 55, REDUCED HNDLG message is displayed. Drive cautiously and check your tire pressures as soon as you can. If the TPM system detects a tire pressure below 5 psi (34 kPa), the TIRE FLAT MAX SPD 55, REDUCED HNDLG warning message is displayed on the Driver Information Center (DIC). See DIC Controls and Displays on page 204 and DIC Warnings and Messages on page 206 for information and details about the DIC operation and displays. 440
