DISTRONIC PLUS
Safety notes
When activated, the DISTRONIC PLUS
adaptive cruise control system increases the
driving convenience afforded by the cruise
control while traveling on expressways and
other major roadways.
R If the DISTRONIC PLUS distance sensor
detects a slower moving vehicle directly
ahead, your vehicle speed will be reduced
so that you follow that vehicle at your
preset following distance.
R If there is no vehicle directly ahead of you,
the DISTRONIC PLUS will function in the
same way as standard cruise control
( Y page 146).
GWarning!
The DISTRONIC PLUS requires familiarity with
its operational characteristics. We strongly
recommend that you review the following
information carefully before operating the
system.
GWarning!
The DISTRONIC PLUS is a convenience
system. Its speed adjustment reduction
capability is intended to make cruise control
more effective and usable when traffic speeds
vary. It is not however, intended to, nor does
it, replace the need for extreme care.
The responsibility for the vehicle’s speed,
distance to the preceding vehicle and, most
importantly, brake operation to ensure a safe
stopping distance, always remains with the
driver.
The DISTRONIC PLUS cannot take street and
traffic conditions into account.
Complex driving situations are not always
fully recognized by the DISTRONIC PLUS. This
could result in wrong or missing distance
warnings.GWarning!
The DISTRONIC PLUS adaptive cruise control
is not a substitute for active driving
involvement. It does not react to pedestrians
or on stationary objects, nor does it recognize
or predict the curvature and lane layout or the
movement of preceding vehicles. The
DISTRONIC PLUS can only apply a maximum
of 40% of the vehicle’s braking power.
The DISTRONIC PLUS may not detect narrow
vehicles possibly driving in front of you, such
as motorcycles and vehicles driving in an
offset formation.
It is the driver’s responsibility at all times to
be attentive to the road, weather and traffic
conditions. Additionally, the driver must
provide the steering, braking and other driving
inputs necessary to remain in control of the
vehicle.
High-frequency sources such as toll stations,
speed measuring systems etc. can cause the
DISTRONIC PLUS system to temporarily
cease functioning.
GWarning!
The DISTRONIC PLUS cannot take road and
traffic conditions into account. Only use the
DISTRONIC PLUS if the road, weather and
traffic conditions make it advisable to travel
at a constant speed.
GWarning!
Use of the DISTRONIC PLUS can be
dangerous on slippery roads. Rapid changes
in tire traction can result in wheel spin and
loss of control.
Driving systems149Controls in detail212_AKB; 2; 41, en-USd2ureepe,Version: 2.11.8.12009-07-17T09:14:21+02:00 - Seite 149Z

Page 152 of 372

The DISTRONIC PLUS does not function in
adverse sight and distance conditions. Do not
use the DISTRONIC PLUS during conditions of
fog, heavy rain, snow or sleet.GWarning!
The DISTRONIC PLUS cannot take weather
conditions into account. Switch off the
DISTRONIC PLUS or do not switch it on if:
R roads are slippery or covered with snow or
ice. The wheels could lose traction while
braking or accelerating, and the vehicle
could skid.
R the DISTRONIC PLUS system sensor covers
are dirty or visibility is diminished due to
snow, rain or fog, for example. The distance
control system functionality could be
impaired.
Always pay attention to surrounding traffic
conditions even while the DISTRONIC PLUS is
switched on. Otherwise, you may not be able
to recognize dangerous situations until it is
too late. This could cause an accident in which
you and/or others could be injured.
GWarning!
The “Resume” function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed.
GWarning!
Close attention to road and traffic conditions
is imperative at all times, regardless of
whether or not the DISTRONIC PLUS is
activated.
Use of the DISTRONIC PLUS can be
dangerous on winding roads or in heavy traffic
because conditions do not allow safe driving
at a constant speed.
The DISTRONIC PLUS will not react to
stationary objects in the roadway (e.g. a
stopped vehicle in a traffic jam or a disabled
vehicle). The DISTRONIC PLUS will also not
respond to oncoming vehicles.
Switch off the DISTRONIC PLUS:
R when changing from the left to the right
lane if vehicles are moving more slowly in
the left lane
R when entering a turn lane or highway off
ramp
R in complex driving situations, such as in
highway construction zones
In these situations, the DISTRONIC PLUS will
continue to maintain the set speed unless
deactivated.
The DISTRONIC PLUS is designed and
intended only to maintain a set speed and
keep a set distance from moving objects in
front of it.
The DISTRONIC PLUS functions in a speed
range of 0 to 120 mph
(Canada: 0 to 200 km/h) if a preceding
vehicle is detected. If no preceding vehicle is
detected the DISTRONIC PLUS functions in a
speed range of 20 to 120 mph
(Canada: 30 to 200 km/h).
Always obey applicable speed limits.
Do not use the DISTRONIC PLUS if you are
driving on a road with steep uphill or downhill
slopes.
When traveling in Canada in a vehicle not
registered in Canada, you must switch off the
radar sensor system ( Y page 144). Canadian
law does not permit the use of the radar
sensor system for vehicles from outside of
Canada. When you switch off the radar sensor
system, the following functions are
deactivated:

vehicle ahead and your vehicle’s current
speed indicate that the DISTRONIC PLUS will
not be capable of slowing the vehicle
sufficiently to maintain the preset following
distance, which creates a danger of a
collision.
Immediately brake the vehicle to increase
your distance to the preceding vehicle. The
warning sound is intended as a final caution
in which you should intercede with your own
braking inputs to avoid a potentially
dangerous situation. Do not wait for the
operation of the warning signal to intercede
with your own braking. This will result in
potentially dangerous emergency braking
which will not always result in an impact being
avoided.
Tailgating increases the risk of an accident.
GWarning!
The DISTRONIC PLUS brakes your vehicle
with a maximum deceleration of 13 ft/s2
(4 m/s2). This corresponds to approximately
40% of the maximum deceleration of your
vehicle.
You must also apply the brakes yourself to
avoid a collision. The DISTRONIC PLUS brakes
the vehicle in an effort to restore the preset
distance or to maintain the set speed.
GWarning!
If you do not receive visual or acoustic
warning signals during a critical traffic
situation, DISTRONIC PLUS has either not
recognized the collision risk, has been
deactivated or is malfunctioning.
Remember, whether or not DISTRONIC PLUS
is operating, it is ultimately always the drivers
responsibility to apply the brakes in order to
control the vehicle and avoid a collision.

GWarning!
The DISTRONIC PLUS switches off and
releases the brakes when the vehicle
decelerates below the minimum speed of
20 mph (30 km/h) by operation of the system
unless the DISTRONIC PLUS detects a vehicle
directly ahead of you. At that time the driver
must apply the brakes in order to reduce
vehicle speed further or bring it to a stop.
Depressing the accelerator pedal does not
deactivate the DISTRONIC PLUS. After a brief
acceleration (e.g. for passing), the
DISTRONIC PLUS will resume the last set
speed.
Setting the following distance in
DISTRONIC PLUS
You can set the specified following distance
for the DISTRONIC PLUS by varying the time
setting between 1.0 and 2.0 seconds. Using
this time setting and the current speed of
your vehicle, the DISTRONIC PLUS calculates
and sets the required following distance to
the preceding vehicle.
The set distance will be shown in the
multifunction display.
GWarning!
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.
XIncreasing distance: Turn distance
setting switch : in direction of arrow ;.
Increasing the distance setting tells the
DISTRONIC PLUS to maintain a greater
following distance to the preceding vehicle.
XDecreasing distance: Turn distance

DISTRONIC PLUS to maintain a shorter
following distance to the preceding vehicle.
Driving with DISTRONIC PLUS
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 PLUS system.
GWarning!
The DISTRONIC PLUS 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:
RYour vehicle can pass another vehicle after
you have changed lanes.

PLUS could lose sight of the preceding
vehicle. Your vehicle could then accelerate
to the previously selected speed.
The DISTRONIC PLUS regulates only the
distance between your vehicle and those
directly ahead of it. It may not register
stationary objects in the road, e.g.:
Ra stopped vehicle in a traffic jam
Ra disabled vehicle
Ran oncoming vehicle
The driver must always be alert, observe all
traffic and intercede as required by means of
steering or braking the vehicle.
GWarning!
The DISTRONIC PLUS should not be used in
snowy or icy road conditions.
The most likely cause for a malfunctioning
system is a dirty sensor (located in the hood
grille and in the bumper), especially at times
of snow and ice or heavy rain.
In such a case, the DISTRONIC PLUS will
switch off, and the message DISTRONIC
PLUS Currently Unavailable See
Operator's Manual appears in the
multifunction display.
For cleaning and care of the sensors, see
(Y page 263).
iIf the message DISTRONIC PLUS
Currently Unavailable See
Operator's Manual disappears during
driving and the last speed stored flashes for
approximately 5 seconds, the dirt (e.g.
slush) has dissolved; the DISTRONIC PLUS
is available again.
Another cause might be that the radar
sensors have been manually switched off in
the instrument cluster control system. Please
verify that the radar sensors are switched on
(Y page 144).
Turns and bends
In turns or bends, the DISTRONIC PLUS may
not detect a preceding vehicle, or it may
detect one too soon. This may cause your
vehicle to brake late or unexpectedly.
Offset driving
A vehicle traveling in your lane but offset from
your direct line of travel may not be detected
by the DISTRONIC PLUS. There will be
insufficient distance to the preceding vehicle.
