Important!
When starting the engine, Distronic goes through an
initialization and self-test phase – this can take up to
2minutes.
The most likely cause for a malfunctioning system is a
by 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 – CLEAN SENSOR!” appears in the
multifunction display.
For cleaning and care of the Distronic sensor see
page 384.
Restart the engine after cleaning the sensor.
The following are some sample situations which may
influence the functions of Distronic.
Wa r n i n g !
Distronic works to maintain the speed selected by
the driver unless a moving obstacle proceeding
directly ahead of it in the same travel direction is
detected (e.g. following another vehicle ahead at a
distance set by Distronic). This means that:• your vehicle can pass another vehicle after you
change lanes,• while in a sharp turn or if the vehicle in front
is in a sharp turn, Distronic could lose sight of
a vehicle traveling in front of it, then your
vehicle could accelerate to the previously
selected speed.Distronic regulates only the distance between your
vehicle and those directly ahead, but does not
register stationary objects in the roadway, e.g.:
• a stopped vehicle in a traffic jam.
• a disabled vehicle.
• an oncoming vehicle.
The driver must always be on the alert and observe
all traffic and intercede with steering and braking
inputs as necessary.Wa r n i n g !
Distronic should not be used in snowy or icy road
conditions.

electronic key or the start-/stop button (vehicles with
KEYLESS-GO), the engine can be turned off by
withdrawing two fuses.

marked on the fuse chart as “ENGINE EMERGENCY
