Users Manual Part 5

The tyre pressures are already being moni‐
tored.
#
Compare the tyre pressure with the recom‐
mended tyre pressure for the current operat‐
ing condition (/ page 493). Observe the
notes on tyre temperature (/ page 492).
%
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 a pressure gauge are higher than those
shown by the on-board computer. In this
case, do not reduce the tyre pressure.
