Compare the tyre pressure with the recom‐
mended tyre pressure for the current operat‐
ing condition (
→
page 430). Observe the
notes on tyre temperature (
→
page 429).
% 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.
