The tire pressures are already being moni‐
tored.

The values displayed in the multifunction dis‐
play may deviate from those of the tire pres‐
sure gauge as they refer to sea level. At high
altitudes, the tire pressure value indicated by
a pressure gauge are higher than those
shown by the on-board computer. In this
case, do not reduce the tire pressure.
