228 Controls in detailDriving systemsThe most likely cause for a malfunctioning
system is a dirty sensor (located behind
the hood grille), especially at times of snow
and ice or heavy rain. In such a case, Dis-
tronic will switch off, and the message:DISTRONIC
CURRENTLY UNAVAILABLE
SEE OPERATORS MANUALappears in the multifunction display.
For cleaning and care of the Distronic sen-
sor, see “Cleaning the Distronic* system
sensor cover” (
page 335).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 insuffi-
cient distance to the vehicle ahead.
iIf the message:DISTRONIC
CURRENTLY UNAVAILABLE
SEE OPERATORS MANUALdisappears during driving and the last
speed stored flashes for approximately
five seconds, the dirt (e.g. slush) has
dissolved; Distronic is again operation-
al.
