Electronic Damping Control
EDC*
If parameters such as road surface quality or
operating conditions such as steering, braking
etc. change, the damping automatically adapts
to the changed circumstances.
iDrive, principle, see page 14.
1. Press the button to call up the start
menu.
2. Move the controller towards "Settings".
3. Select "Car" and press the controller.
4. Select "EDC" and press the controller.
Two programs are available.
Whenever the controller is pressed, you can
change between "Comfort" and "Sports".
Comfort program
The Comfort program can be maintained
across the entire road-speed range and for any
vehicle load.
Sport program
The Sport program should be called up if a pro-
nounced sports characteristic for the shock
absorbers and steering is desired.
Run Flat Indicator RPA
The principle
The Run Flat Indicator monitors the pressures
in the four tyres fitted to the wheels while the
car is being driven. The system reports any sig-
nificant loss of pressure in one tyre in relation to
the others.
In the event of a loss of pressure, the operating
radius and therefore the rotational speed of the
wheels changes. This change is detected and
reported as tyre failure.
Operating requirements
To ensure that tyre failure can be reported reli-
ably, the system must have been initialised
while the tyre pressures are correct.
The system has to be reinitialised every
time tyre pressures are corrected, after
each change of a wheel or tyre, and after a trailer
has been attached or detached.<
System limits
The Run Flat Indicator is unable to warn
the driver of sudden, severe tyre damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tyres over a lengthy period of
time.<
In the following situations, the system could be
slow to respond or operate incorrectly:
> If the system has not been initialised.
> When driving on snow-covered or slippery
surfaces.
> Sporty style of driving: causing the driven
wheels to spin, high lateral acceleration.
> When driving with snow chains
*
.
Initialising the system
Initialising is completed by driving the car;
this process can be interrupted at any
time. Initialising resumes automatically when
you continue your journey. Do not initialise the
system while driving with snow chains
