2007 Cadillac CTS-V Owner's Manual - Page 217

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 on after this warning is acknowledged. See Tire Pressure Light (CTS-V Only) on page 201 for more information. Also see Tire Pressure Monitor System on page 405 for more information on tire pressure specifications. One-to-Four Shift Message (CTS-V Only) This message indicates that you can only shift from FIRST (1) to FOURTH (4) instead of FIRST (1) to SECOND (2). You must complete the shift into FOURTH (4) to turn off this feature. This helps you get the best possible fuel economy. After shifting to FOURTH (4), you may downshift to a lower gear if you prefer. See Manual Transmission Operation on page 122 for more information. Notice: Forcing the shift lever into any gear except FOURTH (4) when the 1 TO 4 SHIFT message comes on may damage the transmission. Shift only from FIRST (1) to FOURTH (4) when the light comes on. 217
