setting and the current speed of your vehicle,
Distronic calculates and sets the required
following distance to the preceding vehicle.
The set distance will be shown in the
multifunction display.
G
Warning!
It is up to the driver to exercise discretion
to select the appropriate setting given road
conditions, traffic, driver’s preferred driving
style and applicable laws and driving
recommendations for safe following
distance.
1
Thumbwheel for setting distance
X
Increasing distance: Turn thumbwheel
1 towards ¯.
Increasing the distance setting tells
Distronic to maintain a greater following
distance to the preceding vehicle.
X
Decreasing distance: Turn thumbwheel
1 towards ®.
Decreasing the distance setting tells
Distronic to maintain a shorter following
distance to the preceding vehicle.
Driving with Distronic
This section describes a number of driving
situations where special precaution is
required on the part of the driver. Be prepared
to brake in such situations. Braking will
deactivate the Distronic system.
G
Warning!
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 of you at
your set distance).
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
previously 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.
