Warning!
Distronic switches off and releases the brakes
when the vehicle decelerates below the
minimum speed of 20 mph (30 km/h) by
operation of the system. At that time the
driver must apply the brakes in order to
reduce vehicle speed further or bring it to a
stop.
Depressing the accelerator pedal does not
deactivate the Distronic. After a brief
acceleration (e.g. for passing), the Distronic
will resume the last set speed.
Setting the following distance in
Distronic
You can set the specified following distance
for Distronic by varying the time setting
between 1.0 and 2.0 seconds. Using this time
setting and the current speed of your vehicle,
Distronic calculates and sets the required
following distance to the preceding vehicle.
The set distance will be shown in the right
multifunction display.
G
Warning!
It is up to the driver to exercise discretion to
select the appropriate setting given road
conditions, traffic, driver's preferred driving
