Tire Pressure Control (RDC)*

The concept

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 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 system

1 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.

Loss of tire pressure

If 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.<
