M Dynamic Driving Control Tire Pressure Warning (RDW)
Whenever it is required, this system
changes the settings of the Servotronic
power steering, and the accelerator
pedal response from a performance-
comfort mode to a pure performance
mode. That is, steering response
becomes more performance-oriented
and the response of the accelerator
pedal is much more spontaneous
(Performance Recognition).
Performance Recognition
With the ignition key in position 2, press
the key (arrow). The indicator lamp illu-
minates.
Deactivating Performance Recognition:
Press the button again; the indicator
lamp goes out.
The coordinated performance-comfort
mode is activated automatically each
time you start the engine.

The concept
RDW monitors the tire pressure at all
four wheels – even while you are driv-
ing. The system provides an alert when-
ever the inflation pressure drops signifi-
cantly below the specified pressure in
one or more tires.
In order for the system to "learn" the
correct tire inflation pressure, check the
inflation pressure in all tires according
to the inflation pressure table beginning
on page 26 and make corrections as
necessary. Then activate the system.
The Check Control (refer to page 73)
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)
until the message "SET TIRE
PRESSURE" is displayed for a few
seconds in the Check Control.
3 After you have driven a few minutes,
RDW transfers the current tire infla-
tion pressures as the nominal values
to be monitored.
You will only have to repeat this proce-
dure following a correction of the tire in-
flation pressure. Otherwise, the system
is automatically activated in ignition key
position 2 and therefore whenever the
vehicle is driven.
