Saving a new reference value for tyre pressure monitoring*
In order for the system for tyre pressure monitoring1 to work correctly, a reference value for the tyre pressure must be saved. This must take place every time the tyres are changed or the tyre pressure is changed so that the system can warn about low pressure correctly.
Perform the following procedure to store a new tyre pressure as a reference value in the system:
Switch off the car.
Inflate the tyres to the correct pressure, see the decal on the door pillar on the driver's side showing the recommended pressure for factory fitted tyres.
Start the car.
Press 
in the centre display.
in the centre display.Press Car status.
Press Store pressure. The car must be running and stationary when storing a tyre pressure.
Note
The Store pressure button is used to save new reference values for tyre pressures in the tyre pressure monitoring system. For safety reasons, it is only available (selectable) when the car is stationary and the engine is running.
The tyre pressure must be saved after adjusting tyre pressure or changing tyres. Adjust the tyre pressure to the recommended values and press Confirm to save the tyre pressure.
Note
To avoid mistaken activation of the Store pressure function, it is necessary to confirm in a second step that the tyre pressure should be saved.
Drive the car until the new tyre pressure has been saved. The new tyre pressure is stored when the car is driven at a speed above 35 km/h (22 mph).
When sufficient data have been collected for the system to be able to detect low tyre pressure, the animation showing the progress of storing the new reference value disappears from the centre display.
If storing fails, a message is shown.
Warning
The exhaust gases contain carbon monoxide, which is invisible and odourless, but highly toxic. The procedure to save a new tyre pressure must therefore always be performed outdoors or in a workshop with exhaust extraction.
