The cruise control speed segments in the
multifunction display goes out and an acous-

G
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 accel-
eration (e.g. for passing), the Distronic will
resume the last set speed.
Setting the following distance in Dis-
tronic
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 fol-
lowing distance to the preceding vehicle.
The set distance will be shown in the multi-
function 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
style and applicable laws and driving rec-
ommendations for safe following distance.

Driving with Distronic
This section describes a number of driving
situations where special precaution is
required on the part of the driver. Be prepared
to brake in such situations. Braking will deac-
tivate the Distronic system.
G
Warning!
Distronic works to maintain the speed
selected by the driver unless a moving
obstacle proceeding directly ahead of it in
the same travel direction is detected (e.g.
following another vehicle ahead of you at
your set distance).
