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

After you have driven for a few minutes, the
system checks whether the current tyre pres‐
