System not calibrated

If the system has not been calibrated or one or more tyres have
been replaced, the symbol and message shown in example
be displayed. Simultaneously, the specific warning light on the
instrument panel (see page 107) starts flashing, and continues to
flash for 90 seconds.
When the display cycle ends (20 seconds), the symbol and message

the engine off. Once the MENU screen page appears, select the
items "Car setup", "Calibr. TPMS".
