Distronic displays in the speedometer
dial
1Set speed
If Distronic is activated, one or two seg-
ments come on around the set speed.1Segments
If Distronic detects a vehicle directly
ahead, the segments (representing the dif-
ference) between the speed of the vehicle
ahead and the set speed come on.
If Distronic calculates that there is a dan-
ger of collision when the distance warning
function is activated (
page 238):


The Distronic warning lampl in the
instrument cluster comes on.


An intermittent warning sounds.

Immediately brake the vehicle to avoid
a collision.
Under no circumstances should the
driver await the intermittent warning
sound before braking. See the follow-
ing warning note.
The intermittent warning sound ceases
and the Distronic warning lampl
goes out when the necessary distance
to the vehicle ahead is reestablished.
iThe vehicle speed displayed on the
speedometer can briefly vary from the
speed setting on the Distronic system.

232 Controls in detailDriving systems
Distronic menu in the control system
In the Distronic menu you see the current
settings for Distronic. What appears in the
display depends on whether Distronic and
the distance warning function are turned
on or off.
Press buttonè orÿ repeatedly
until you see one of the following dis-
plays.
Warning!
G
An intermittent warning sounds and the
Distronic warning lamp in the instrument
cluster is illuminated if the Distronic system
calculates that the distance to the vehicle
ahead and your vehicle’s current speed indi-
cate that Distronic 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
the distance to the vehicle in front of you.
The warning sound is intended as a final cau-
tion that you have not interceded with your
own braking inputs to avoid a potentially
dangerous situation. Do not wait for the op-
eration of the warning signal to intercede
with your own braking, as that will result in
potentially dangerous emergency braking
which will not always result in an impact be-
ing avoided.
Tailgating increases the risk of an accident.
Warning!
G
Distronic brakes your vehicle with a maxi-
mum of 6.5 ft/s
2 (2 m/s
2). This corre-
sponds to about 20% of the maximum
deceleration ability of your vehicle.
Distronic brakes the vehicle in an effort to
restore the preset distance or to maintain
the speed. The brake pedal is automatically
applied as this happens which results in the
brake pedal moving.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the Distronic system.
Do not place your foot under the brake pedal
– your foot could become caught.

You can activate Distronic if

you are driving between 25 mph
(40 km/h) and 110 mph (180 km/h)


the ESP is activated (
page 79)
If Distronic has not been activated after
pressing the cruise control lever you will
see the message

in the multifunction
display.
In the following cases you cannot activate
Distronic:


up to two minutes after starting the en-
gine.


when you brake.


if you have set the parking brake.


if the gear selector lever is in
positionP, R or N.


if ESP is switched off.Setting the current speed

Accelerate or decelerate to the desired
speed.

Briefly lift or depress the cruise control
lever.
Distronic is activated and the current
speed is set.

Remove your foot from the accelerator
pedal.Setting a higher speed

Briefly tip cruise control lever in the di-
rection of arrow1 (
page 233) to in-
crease vehicle speed in increments of
5 mph (Canada: 10 km/h).
The new speed is set.
The stored speed is displayed in the
multifunction display for approximately
five seconds (
page 233), and one or
two segments around the stored speed
come on, on the speedometer
(
page 231).
iIf you do not take your foot off of the
accelerator completely, the following
message will appear in the multifunc-
tion display: Distronic override
.
Distronic will not work to maintain the
distance to slower moving vehicles in
front of you. Your vehicle speed will
then be determined only by the accel-
erator pedal position.
iDepressing the accelerator pedal does
not deactivate Distronic. After brief ac-
celeration (e.g. for passing), the cruise
control will resume the last speed set.

pedal.
iWhen you use the cruise control lever
to decelerate, the transmission will au-
tomatically downshift if the rate of de-
celeration is too low.
Warning!
G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to the pre-
set speed could cause an accident and/or
serious injury to you and others.

Distronic
You can set the specified following dis-
tance for Distronic by varying the time set-
ting between 1.0 and 2.0 seconds. Using
this time setting and the current speed of
your vehicle, Distronic calculates and sets
the required following distance to the vehi-
cle ahead. The set distance will be shown
in the multifunction display field.
The thumbwheel for making the time set-
ting is located on the lower section of the
center console.
iThe following message will appear in
the multifunction display for approxi-
mately five seconds:

.
The last stored speed is deleted when
you turn off the engine.
Warning!
G
Distronic switches off and releases the
brakes when the vehicle decelerates below
the minimum speed of approximately
25 mph ( 40 km / h) by operation of the sys-
tem. At that time the driver must apply the
brakes in order to reduce vehicle speed fur-
ther or bring it to a stop.
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.
