DISTRONIC Plus requires familiarity with its
operational characteristics. We strongly rec-
ommend that you review the following infor-
mation carefully before operating the
system.Warning!
G
DISTRONIC Plus cannot take street and traf-
fic conditions into account. Only use
DISTRONIC Plus if the road, weather and
traffic conditions make it advisable to travel
at a steady speed.Warning!
G
Use of DISTRONIC Plus can be dangerous
on slippery roads. Rapid changes in tire trac-
tion can result in wheel spin and loss of con-
trol.
DISTRONIC Plus does not act upon adverse
sight distance conditions. Do not use
DISTRONIC Plus during conditions of fog
and heavy rain, snow or sleet.Warning!
G
DISTRONIC Plus cannot take weather condi-
tions into account. Switch off
DISTRONIC Plus or do not turn it on if:
roads are slippery or covered with snow
or ice. The wheels could lose traction
while braking or accelerating, and the
vehicle could skid.
the sensor is dirty or visibility is
diminished due to snow, rain or fog. The
distance control could be impaired.
Always pay attention to traffic conditions
even while DISTRONIC Plus is switched on.
Otherwise, you may not be able to recognize
dangerous situations until it is too late and
could cause an accident resulting in person-
al or fatal injury to you or others.
Warning!
G
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.Warning!
G
Close attention to road and traffic condi-
tions is imperative at all times, regardless of
whether or not DISTRONIC Plus is activated.
Use of DISTRONIC Plus can be dangerous
on winding roads as conditions do not allow
safe driving at a steady speed.
DISTRONIC Plus may not react to stationary
objects in the roadway (e.g. a stopped vehi-
cle in a traffic jam or a disabled vehicle).
DISTRONIC Plus will also not respond to on-
coming vehicles.

Active Body Control (ABC)*
The ABC system automatically selects the
optimum suspension tuning and ride
height for your vehicle.
The ABC system consists of an active, hy-
draulically controlled suspension and
damping system.
Vehicle level control with ABC*
Your vehicle automatically adjusts its ride
height to:
reduce fuel consumption
increase vehicle stability
The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed:
With increasing speed, ride height is re-
duced by up to approximately 0.6 in
(15 mm).
With decreasing speed, the ride height
is again raised to the selected vehicle
level.The following vehicle level settings can be
selected when the vehicle is stationary:
Select the “Raised” level setting only when
required by current driving conditions.
Otherwise:
Fuel consumption may increase.
Handling may be impaired.

These height adjustments are so small that
you may not notice any change.

Warning!
G
Please note that objects which do not touch
the ground, such as the bumper of a vehicle
parked behind you, a trailer hitch, or the
back of a truck, may appear to be further
away than they actually are. In this case, you
should not use the guide lines to judge dis-
tance as the use of the guide lines to judge
distance increases the risk of impacting the
objects.
Even when the object you approach is di-
rectly on the ground (and nothing on the ob-
ject extends above the ground beyond the
object's contours directly touching the
ground) and no objects that do not touch
the ground, such as the bumper of a vehicle
parked behind you, a trailer hitch, or the
back of a truck are in the path, do not ap-
proach the object on the ground any closer
than red guide line4.
