Driving with Distronic
This section describes a number of driving
situations where special precaution is re-
quired on the part of the driver. Be pre-
pared to brake in such situations. This will
deactivate the Distronic system.
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,
Distronic will switch off, and the message
Distronic Currently unavailable. See
Oper. Manual
appears in the multifunction
display.
For cleaning and care of the Distronic sen-
sor, see “Cleaning the Distronic* system
sensor cover” (
୴ page 325).
Warning! G
Distronic works to maintain the speed se-
lected by the driver unless a moving obsta-
cle proceeding directly ahead of it in the
same travel direction is detected (e.g. fol-
lowing another vehicle ahead of you at your
set distance. This means that:
ț Your vehicle can pass another vehicle
after you have changed lanes.
ț 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 set speed.
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.:
ț a stopped vehicle in a traffic jam
ț a disabled vehicle
ț an oncoming vehicle
The driver must always be alert, observe all
traffic and intercede as required by means
of steering or braking the vehicle.
Warning! G
Distronic should not be used in snowy or icy
road conditions.

If the message
Distronic available
again
appears in the multifunction display dur-
ing driving, the dirt (e.g. slush) has dissolved.
Distronic is available again if you reactivate it
(
