Setting the following distance in
DISTRONIC Plus
You can set the specified following dis-
tance for 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, DISTRONIC Plus cal-
culates and sets the required following dis-
tance to the preceding vehicle. The set
distance will be shown in the multifunction
display.The distance setting switch for the target
distance is located on the DISTRONIC Plus
lever.

Setting the automatic transmission to neu-
tral positionN while driving cancels the
DISTRONIC Plus. However, the automatic trans-
mission should not be set to neutral positionN
while driving except to coast when the vehicle is
in danger of skidding (e.g. on icy roads).
i
Depressing the accelerator pedal does not
deactivate DISTRONIC Plus. After brief accelera-
tion (e.g. for passing), DISTRONIC Plus will re-
sume to the last set speed.
Warning!
G
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 recom-
mendations for safe following distance.

458 Controls in detailDriving systemsIncreasing distance
Increasing the distance setting causes
DISTRONIC Plus to maintain a greater fol-
lowing distance to the preceding vehicle.

rection 3.Driving with DISTRONIC Plus
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. Braking
will deactivate the DISTRONIC Plus sys-
tem.
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 Plus will switch off, and the
message:
Warning!
G
DISTRONIC Plus works to maintain the
speed selected by the driver unless a mov-
ing 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:

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 Plus
could lose sight of a vehicle traveling in
front of it, then your vehicle could accel-
erate to the previously selected speed.
DISTRONIC Plus regulates only the distance
between your vehicle and those directly
ahead of it. It may not register stationary ob-
jects in the road, e.g.:

a stopped vehicle in a traffic jam


a disabled vehicle


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 Plus should not be used in
snowy or icy road conditions.

Cross-traffic
DISTRONIC Plus may inadvertently detect
crossing vehicles. If you switch on DIS-
TRONIC Plus, for example, at a traffic light
with cross-traffic, the vehicle may sudden-
ly start to drive off.
Active Body Control (ABC)
The ABC system is an active, comput-
er-controlled system that hydraulically ad-
justs the suspension at all four wheels in
response to various driving situations. It
automatically selects the optimum suspen-
sion tuning and ride height for your vehicle.Vehicle level controlWarning!
G
When you switch off the engine, the entire
vehicle is lowered. You should therefore
make sure that no one is near the wheel
housing or under the vehicle when you
switch off the engine. Otherwise, parts of
the individuals body could be trapped.!
When you switch off the engine, the entire
vehicle is lowered. When parking, position your
vehicle in such a way that it will not scrape
against a curb, for example, when it is lowered.
Your vehicle could otherwise be damaged.
i
CL 63 AMG and CL 65 AMG only:
When you switch off the engine, the entire vehi-
cle is lowered by 0.2 in (5 mm).
Warning!
G
To help avoid personal injury, keep hands
and feet away from wheel housing area, and
stay away from under the vehicle when
lowering the vehicle chassis.

need for extreme care. The responsibility
during parking and other critical maneuvers
always remains with the driver.Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.!
Special attention must be paid to objects
with smooth surfaces or low silhouettes (e.g.
trailer couplings, painted posts, elevated cross-
bars or road curbs). Such objects may not be
detected by the system and can damage the
vehicle.

!
During parking maneuvers, pay special at-
tention to objects located above or below the
height of the sensors (e.g. street curbs, painted
posts, or trailer hitches etc.). The Parktronic sys-
tem will not detect such objects at close range
and damage to your vehicle or the object may
result.
Ultrasonic signals from outside sources (e.g.
truck air brakes, car wash, or jackhammers) may
impair the operation of the Parktronic system.
