Tire pressure X 489 Press the 9 or : button to select Tire Pressure. X Press the a button. The current tire pressure for each wheel will be displayed in the multifunction display. If the vehicle has been parked for longer than 20 minutes, the Tire Pressures Displayed After Driving A Few Minutes message appears in the display. After a teach-in period, the tire pressure monitor automatically recognizes new wheels or new sensors. As long as a clear allocation of the tire pressure values to the individual wheels is not possible, the Tire Pressure Monitor Active message is shown instead of the tire pressure display. The tire pressures are already being monitored. short time. This is rectified after a few minutes of driving, and the tire pressures are displayed for the correct positions. Restarting the tire pressure monitor G Warning It is the driver's responsibility to set the tire inflation pressure to the recommended cold tire inflation pressure. Underinflated tires affect the ability to steer or brake the vehicle. You might lose control over the vehicle. TPMS warning messages If the tire pressure monitor detects a significant pressure loss on one or more tires, a warning message is shown in the multifunction display. A warning tone also sounds and the tire pressure warning lamp lights up in the instrument cluster. For each tire that is affected by a significant loss of pressure, the tire pressure is shown in yellow. If the Correct Tire Pressure message appears in the multifunction display: X Check the tire pressure on all four wheels and correct it if necessary. i If the wheel positions on the vehicle are interchanged, the tire pressures may be displayed for the wrong positions for a i Canada only: in most cases, the tire pressure monitor recognizes the new reference values automatically.

When you restart the tire pressure monitor, all existing warning messages are deleted and the warning lamps go out. The monitor uses the currently set tire pressures as the reference values for monitoring. The TPMS must be restarted when you set the tire pressure to a new value (as a result of changed handling or load characteristics, for example). The TPMS then monitors the new tire pressure values.
