This means that:
R
Your vehicle can pass another vehicle
after you have changed lanes.
R
While in a sharp turn or if the preceding
vehicle is in a sharp turn, Distronic could
lose sight of the preceding vehicle. Your
vehicle could then accelerate to the pre-
viously selected speed.
Distronic regulates only the distance
between your vehicle and those directly
ahead of it, but does not register stationary
objects in the road, e.g.:
R
a stopped vehicle in a traffic jam
R
a disabled vehicle
R
an oncoming vehicle
The driver must always be alert, observe all
traffic and intercede as required by means
of steering or braking the vehicle.
Distronic should not be used in snowy or
icy road conditions.
The most likely cause for a malfunctioning
system is a dirty Distronic system sensor
cover (located in the hood grille), especially
at times of snow and ice or heavy rain.
In such a case, Distronic will switch off, and
the message DISTRONIC Currently
Unavailable – See Operator’s Manual
appears in the multifunction display.
For cleaning and care of the Distronic system
sensor cover, see (

If the message DISTRONIC Currently
Unavailable – See Operator’s Man-
ual disappears during driving and the last
set speed flashes for approximately 5 sec-
onds, the dirt (e.g. slush) has dissolved;
Distronic works again.
Turns and bends
In turns or bends, Distronic may not detect a
moving vehicle in front, or it may detect one
too soon. This may cause your vehicle to
brake late or unexpectedly.
Offset driving
A vehicle traveling in your lane but offset from
your direct line of travel may not be detected
by Distronic. There will be insufficient dis-
tance to the preceding vehicle.
