The system may be impaired or may not function
in the following situations:

there is a sudden pressure loss caused, for
R
example, by a foreign object penetrating the
tire
there is a malfunction caused by another

process of the system is not yet complete.
The tire pressures are already being moni‐

The teach-in process takes longer if you have
engaged the differential locks. Check the tire
pressure again at a later date.
Compare the tire pressure with the recom‐

% 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.
