Tire Pressure Control (RDC)
*
The Tire Pressure Control system as-
sumes the task of regular tire pressure 
checks for you. Tire pressures are mon-
itored at all four wheels, even when the 
vehicle is moving.
Behind the valve stem in every wheel, 
there is an electronic chip which is de-
signed for severe-duty applications and 
long service life. It contains a pressure 
sensor, a transmitter and a battery. The 
pressure is measured in extremely short 
time intervals and then transmitted by a 
radio signal. If an irregularity is de-
tected, the transmission rate is in-
creased.

Near every wheel, there are antennas in 
the body which receive the signals from 
all four wheels. A central electronics 
system evaluates the quadruple signals 
which it receives and forwards any 
changes.
The RDC provides an important contri-
bution to driving safety.
