Tire Pressure Warning Message When you see this flashing symbol, one or more of the vehicle's tires is either under or over-inflated. To acknowledge this warning, press either button on the outboard switch on the left spoke of the steering wheel. There are three levels of warning for this display: 1. High Tire Pressure (above 42 psi (290 kPa)) 2. Low Tire Pressure (below 25 psi (170 kPa)) 3. Flat Tire (below 5 psi (35 kPa)) For conditions 1 and 2, this warning will flash five times and the display will then show the tire pressure gage. For condition 3, this warning will flash continuously until the driver acknowledges it. In any of the three cases, the warning will redisplay every 10 minutes until the situation is corrected. Conditions 2 and 3 will also display a warning light elsewhere on the cluster that will stay illuminated after this warning is acknowledged. See Tire Pressure Light on page 3-45 for more information. Also see Tire Pressure Monitor System (CTS-V) on page 5-65 for more information on tire pressure specifications. 3-57
