process of the system is not yet complete. The
tyre pressures are already being monitored.
Compare the tyre pressure with the recom-

mended tyre pressure for the current operat-
ing condition ( page 384). Additionally,

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