Compare the tyre pressure with the recom-
mended tyr
e pressure for the current operat-
ing condition (/ page 395). Additionally,
observe the notes on cold tyres
(/ page 394).
%
The values displayed in the on-board com-
put
er 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.

Aer you have been driving for a few minutes,
the system checks whether the current tyre
pressures are within the specied range. The
current tyre pressures are then accepted as
reference values and monitored.
