Briefly lift the cruise control lever up to
the resistance point in direction of
arrow1 (

!
Setting the automatic transmission toN
while driving cancels the cruise control.
However, the automatic transmission should not
be set toN 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 the cruise control. After a brief accel-
eration (e.g. for passing), the cruise control will
resume the last set speed.
i
The set value is increased in 1 mph
(Canada: 1 km/h) increments each time you lift
the cruise control lever up to the resistance
point.
Warning!
G
You can increase the vehicle speed in
5 mph (Canada 10 km/h) increments.
When using this feature, keep in mind that it
may take a brief moment until the vehicle
has reached the set speed.
Increase the vehicle speed to a value that
the prevailing road conditions permit. Other-
wise, sudden and unexpected acceleration
of the vehicle could cause an accident
and/or serious injury to you and others.i
The set value is increased in
5 mph (Canada: 10 km/h) increments each time
you lift the cruise control lever past the
resistance point.

250 Controls in detailDriving systems
Briefly press the cruise control lever
down past the resistance point in direc-
tion of arrow2 (
page 246).

Release the cruise control lever.
The vehicle speed decreases in incre-
ments of 5 mph (Canada: 10 km/h).Setting to last stored speed
(“Resume” function)

Briefly pull the cruise control lever in di-
rection of arrow4 (
page 246).
The cruise control resumes to the last
set speed, or if no speed is stored, it
will set and store the current speed.

Remove your foot from the accelerator
pedal.
The last set speed appears in the multi-
function display for approximately
5 seconds.
Distronic*
When activated, the Distronic adaptive
cruise control system increases the driving
convenience afforded by the cruise control
while traveling on expressways and other
major roadways.

If the Distronic 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.


If there is no vehicle directly ahead of
you, Distronic will function in the same
way as standard cruise control
(page 245).
i
The new speed is set and the vehicle will
decelerate. Keep in mind that it may take a brief
moment until the vehicle has reached the set
speed.
Warning!
G
The set speed stored in memory should only
be set again if prevailing road conditions
permit. Possible acceleration or decelera-
tion differences arising from returning to the
preset speed could cause an accident
and/or serious injury to you and others.

Setting the following distance in
Distronic
You can set the specified following
distance for Distronic by varying the time
setting between 1.0 and 2.0 seconds. Us-
ing this time 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
(page 255).
The distance setting switch for the time
setting is located on the cruise control le-
ver on the left-hand side of the steering
column.1Distance setting switch
2To decrease distance
3To increase distance
Increasing distance
Increasing the distance setting tells
Distronic to maintain a greater following
distance to the preceding vehicle.

Turn distance setting switch1 in
direction of arrow3.
Warning!
G
Distronic 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. At that time the
driver must apply the brakes in order to
reduce vehicle speed further or bring it to a
stop.!
Setting the automatic transmission toN
while driving cancels the Distronic. However, the
automatic transmission should not be set toN
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 the Distronic. After a brief accelera-
tion (e.g. for passing), the Distronic will resume
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.

261 Controls in detail
Driving systems
Decreasing distance
Decreasing the distance setting tells
Distronic to maintain a smaller following
distance to the preceding vehicle.
Turn distance setting switch1 in
direction of arrow2.
Driving with Distronic
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 system.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 will switch off, and the message
DISTRONIC currently unavailable
– See
Operator’s Manual
appears in the multi-
function display.
For cleaning and care of the Distronic sen-
sor, see “Cleaning the Distronic* system
sensor cover” (
page 408).
Warning!
G
Distronic works to maintain the speed se-
lected by the driver unless a moving obsta-
cle proceeding directly ahead of it in the
same travel direction is detected (e.g. fol-
lowing another vehicle ahead of you at your
set distance).
This means that:

Your vehicle can pass another vehicle
after you have changed lanes.


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 be-
tween your vehicle and those directly ahead
of it, but does not register stationary objects
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 should not be used in snowy or icy
road conditions.
i
If the message
DISTRONIC available
again
appears during driving the dirt (e.g.
slush) has dissolved; Distronic works again, if
you reactivate it (

For information on how to program the set
speed while driving, see “Adjusting Down-
hill Speed Regulation speed with DSR
switched on” (
page 266).
Warning!
G
If the accelerator pedal is depressed while
the Downhill Speed Regulation is activated,
the vehicle can drive faster than the pro-
grammed set speed. You should therefore
drive downhill with particular caution as it
could otherwise lead to an accident and/or
serious injury to you or others. Keep in mind
that as soon as you remove the foot from
the accelerator pedal with the DSR switched
on, the DSR will start regulating the vehicle’s
speed including use of brakes if required.
Depending on the programmed set speed,
actual vehicle speed and gradient, the DSR
can cause the vehicle to slow down rapidly.
Sudden and unexpected deceleration can
result in loss of vehicle control, causing an
accident and/or serious personal injury to
you and others.
i
The DSR can only be switched on if the vehi-
cle speed is below 18 mph (Canada: 30 km/h).
