Tire Pressure Control (RDC)
*
The conceptThe 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 to "learn" the cor-
rect tire inflation pressure, first check 
the tire inflation pressure in all tires. 
Then compare these pressures with the 
tire inflation pressure chart (page 28) 
and adjust if necessary. Then activate 
the system. 
This indicator lamp in the instru-
ment cluster informs you when-
ever the tire pressure is not nor-
mal.
Activate the system1 Turn ignition key to position 2 
2 Press the switch long enough for the 
indicator lamp in the instrument clus-
ter to light up yellow for a few seconds
3 After a few minutes of driving, the 
RDC sets the current inflation pres-
sure in the tires as the target value to 
be monitored.
You will only have to repeat this proce-
dure if the tire inflation pressure must 
be corrected. Otherwise, the RDC func-
tions automatically when the ignition 
key is in position 2, and thus operates 
whenever the vehicle is driven.462de228
Loss of tire pressureIf the inflation pressure has dropped too 
much over a period of time (which is 
normal for any tire), the indicator lamp 
will come on with a yellow lamp.
This alerts you to have the tires inflated 
to the specified pressures as soon as 
possible.
If you are prompted to check the 
tire pressure shortly after a cor-
rection has been made, this indicates 
that the corrected values were not ac-
curate. Please check the inflation pres-
sure again and make corrections ac-
cording to the inflation pressure table. 
Then activate the system once again.<
