Mercedes-Benz 2003 S 430 Operator's Manual page 209

Distronic regulates only the distance be-
tween your vehicle and those directly ahead
of it, but does not register stationary objects
in the road, e.g.:
a stopped vehicle in a traffic jam
a disabled vehicle
an oncoming vehicle
The driver must always be on the alert, ob-
serve all traffic and intercede as required by
steering or braking the vehicle.
Warning!
Distronic should not be used in snowy or icy
road conditions.
The 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 - CLEAN SENSOR! SEE
appears in the multifunc-

sor, see "Cleaning the Distronic* system
sensor cover" ( page 285).

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
