Set/Push Button Switch

The push button (with tire failure symbol) is mounted below the instrument cluster to the right of the steering wheel. The push button is used to carry out the following functions:

• Initialization of the system - after changing inflation pressures or tires.
• Switching the RDW system OFF - After switching the ignition switch ON, briefly press the button "TIRE MONITORING INACTIVE" will be displayed in the matrix.
• Self diagnosis of the control module (only for manufacturing purposes) - however if the push button is pressed and held while switching the ignition ON, "TIRE PRESSURE INACTIVE" will be displayed in the matrix.
