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.
G
Warning!
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 (Y page 244).
i
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.
