Minimum speed for
transmission of the RDC
measured values:
min 30 km/h
The display shows
--
for each
tyre until the tyre-pressure sig-
nal is received for the first time.
The sensors continue to trans-
mit the measured-value signals
for some time after the vehicle
comes to a stop.
Time for transmission of
measured values after
vehicle comes to a stop:
min 15 min
An error message is issued if
wheels without sensors are fit-
ted to a vehicle equipped with
an RDC control unit.
Tyre pressure ranges
The RDC control unit distin-
guishes between three tyre
pressure ranges matched to
the vehicle:
Tyre pressure within permit-
ted tolerance.
Tyre pressure close to limit of
permitted tolerance.
Tyre pressure outside permit-
ted tolerance.
Temperature compensation
Tyre pressure is a temperature-
sensitive variable: pressure in-
creases as tyre-air temperature
rises and decreases as tyre-air
temperature drops. Tyre-air
temperature depends on ambi-
ent temperature as well as on
the style of riding and the dura-
tion of the ride.
The tyre pressures
are shown in the TFT
display as temperature
compensated and always
refer to the following tyre air
temperature:
20 °C
The air lines available to the
public in petrol stations and
motorway service areas have
gauges that do not compensate
for temperature; the reading
shown by a gauge of this
nature is the temperature-
dependent tyre-air pressure. As
a result, the values displayed
there usually do not correspond
to the values displayed in the
display.
