ASC+T/DSC* Tire Pressure Control (RDC)*
To reactivate the system
Press the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with ASC+T/DSC.
An appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the
system as an excuse for taking risks.<
For additional details concerning
ASC+T/DSC, please refer to the
chapter describing "Advanced
technology" on page 207.
The concept
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 system to "learn" the
correct tire inflation pressure, check the
inflation pressure in all tires. Refer to
the table of "Tire inflation pressures"
beginning on page 29 and make any
necessary corrections. Then activate
the system.
This indicator lamp in the in-
strument cluster or the Check
Control will inform you if the
tire pressure is not correct.
Activate the system
1 Turn the ignition key to position 2 (do
not start the engine).
2 Press and hold the button (arrow) un-
til the yellow indicator lamp in the in-
strument cluster comes on for a few
seconds or the message "SET TIRE
PRESSURE" appears in the Check
Control.
3 After you have driven for a few min-
utes, the RDC will import the current
inflation pressure in the tires as the
target values which the system will
monitor.
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.
