The RDC monitors the tire pressures at 
all four wheels, even when the vehicle 
is moving. The system provides an alert 
whenever the inflation pressure drops 
significantly below the specified pres-
sure in one or more tires. 

In order for the RDC system to "learn" 
the correct tire inflation pressure, first 
check the tire inflation pressure in all 
tires. Then compare these pressures 
with the tire inflation pressure chart 
(page 

activate the system. 

This indicator lamp in the instru-
ment cluster informs you when-
ever the tire pressure is not 

normal.

Depending on the type of equipment, 
the switch either has the letters RDC on 
it or the RDC-symbol.

1 Turn the ignition key to position 2 

(do not start the engine).

2 Press the switch long enough for the 

indicator lamp in the instrument 
cluster to light up yellow for a few 
seconds.

3 After a few minutes driving time, the 

RDC sets the current inflation pres-
sure in the tires as the target values 
to be monitored.

You will only have to repeat this proce-
dure following a correction of the tire 
inflation pressure. Otherwise, the RDC 
functions automatically when the igni-
tion key is in position 2, and thus oper-
ates whenever the vehicle is driven.

If the inflation pressure has dropped 
significantly over a long period of time 
(which is normal for any tire), the indi-
cator lamp will come on with a yellow 
lamp.

This alerts you that you should have the 
tires inflated to the specified pressures 
as soon as possible.

If you are prompted to check the 
tire pressure shortly after a 

correction has been made, this indi-
cates that the corrected values were 
not accurate. Please check the inflation 
pressure again and make corrections 
according to the inflation pressure 
table. Then activate the system once 
again.
