Tyre pressure close to limit
of permitted toleranceGeneral warning light
lights up yellow.
The critical tyre pressure
flashes.
Measured tyre pressure is
close to the limit of permitted
tolerance. Correct the tyre pressure as
stated on the inside cover of
the Rider's Manual.
The tyre-pressures listed
on the inside cover are
temperature-compensated;
the reference tyre temperat-
ure for these readings is al-
ways 20 °C. The procedure
for correctly tyre pressures
when the tyres are not at this
reference temperature is as
follows:
Calculate the difference
between the specified value
stated in the Rider's Manual and the reading shown by the
RDC system. Use the public
air line at a petrol station or
motorway service area to
adjust the tyre pressure by
this amount.
Tyre pressure outside
permitted tolerance
General warning light
flashes red.
The critical tyre pressure
flashes.
Measured tyre pressure is
outside permitted tolerance. Check the tyre for damage
and to ascertain wheth-
er the motorcycle can be
ridden with the tyre in its
present condition.
If the motorcycle can be rid-
den with the tyre in its present
condition: Incorrect tyre pressures
impair the motorcycle's
handling characteristics.
If tyre pressure is incorrect it
is essential to adapt your style
of riding accordingly.
Correct the tyre pressure at
the earliest possible oppor-
tunity.
Have the tyre checked for
damage by a specialist
workshop, preferably an
authorised BMW Motorrad
dealer.
If you are unsure whether the
motorcycle can be ridden with
the tyre in its present condi-
tion: Do not continue your jour-
ney.
Notify the breakdown ser-
vice.

Tyre pressure control
RDC
OE
FunctionA sensor integrated into each
tyre measures the air tem-
perature and the air pressure
inside the tyre and transmits
this information to the control
unit.
Each sensor has a
centrifugal-force tripswitch
that does not enable
transmission of the measured
values until the motorcycle
has accelerated to about
30 km/h. The display shows--
for each tyre until the
tyre-pressure signal is
received for the first time. The
sensors continue to transmit
the measured-value signals
for approximately 15 minutes
after the motorcycle comes to
a stop. The control unit can
administrate four sensors, so
two different sets of wheels
with RDC sensors can be
alternated on the motorcycle.
An error message is issued
if wheels without sensors
are fitted to a motorcycle
equipped with an RDC control
unit.
Temperature
compensationThe tyre-pressure readings
shown by the multifunction
display are temperature-
compensated; the reference
tyre temperature for these
readings is always 20 °C.
The air lines available to
the public in petrol stations
and motorway service areas
almost invariably show
temperature-dependent
tyre pressures, so in most
instances these gaugereadings will not tally with
the readings shown by the
multifunction display.
Tyre-pressure rangesThe RDC control unit differ-
entiates between three air-
pressure ranges, all of which
are parameterised for the mo-
torcycle:
Air pressure within permit-
ted tolerance.
Air pressure close to limit of
permitted tolerance.
Air pressure outside permit-
ted tolerance.Brake system, generalDescending mountain

There is a danger of the
brakes fading if you use
only the rear brakes when
descending mountain passes.
