Saving new reference values for tire inflation pressure monitoring*
In order for the tire pressure monitoring system1 to function correctly, tire pressure reference values must be saved correctly. To help ensure that the system can correctly alert the driver of low inflation pressure, this must be done each time the tires are changed or the inflation pressure is adjusted.
To store the new inflation pressure as a reference value in the system:
Switch off the ignition.
Inflate the tire to the correct inflation pressure; see the tire pressure placard on the driver's side B pillar for recommended pressures for factory-mounted tires.
Start the vehicle.
Tap 
in the center display.
in the center display.Tap Car status.
Tap Store pressure. When the inflation pressure is stored, the vehicle must be on and stationary.
Note
The Store pressure button is used to save new reference values for inflation pressure in the tire pressure monitoring system. For safety reasons, it is only available (selectable) when the vehicle is stationary and the engine is running.
The inflation pressure must be saved after adjusting the inflation pressure or if the tire is replaced. Adjust the inflation pressure to the recommended value and tap Confirm to store the inflation pressure.
Note
To prevent the Store pressure function from being activated inadvertently, it is necessary to confirm in a second step that the inflation pressure should be saved.
Drive the vehicle until the new inflation pressure has been saved. The new inflation pressure is stored when the vehicle is driven at speeds over 35 km/h (22 mph).
When enough data has been collected for the system to detect low inflation pressure, the animation showing the progress of the procedure for storing a new reference value will disappear from the center display.
If storing cannot be performed, a message will be displayed.
