You can activate Distronic if


the vehicle speed is within a certain
range. The range is between
20 mph (30 km/h) and 110 mph
(180 km/h).


the ESP

When Distronic is activated the speedome-
ter display will show a message such as
DTR 60 mph
.
If Distronic is deactivated, the speedome-
ter display will show the message

.
In the following cases you cannot activate
Distronic:


up to 2 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.

iIf you do not take your foot off of the
accelerator completely, the following
message will appear in the speedome-
ter display field:DTR override
.
The distance to slower moving vehicles
in front of you will not be set. Your ve-
hicle speed will then be determined
only by the accelerator 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.
iWhen you use the cruise control lever
to decelerate, the brakes will be ap-
plied to support deceleration.
In addition, the transmission will auto-
matically downshift on long downhill
grades.

or

Step on the brake pedal.
Distronic will be deactivated. The last
speed set will be stored into memory.Distronic deactivates automatically when


you set the parking brake

You move the gear selector lever into
positionN.
A signal will sound. The
DTR off
mes-
sage appears in the speedometer dis-
play for approximately 5 seconds.
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 endanger yourself and oth-
ers.
iThe 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 25 mph (40 km / h)
or, depending on vehicle production date,
20 mph (30 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.

216 Controls in detailDriving systemsWhen pressing the brake pedal, the warn-
ing sound ceases. The warning sound will
also cease when the distance to the vehi-
cle ahead is sufficient again without apply-
ing the brakes. In this case, the distance
warning lamp will also go out.
Activating

Press switch1.
The indicator lamp on the switch
comes on. A loudspeaker symbol ap-
pears in the speedometer display
(page 211).
Deactivating

Press switch1 once more.
The indicator lamp on the switch goes
out. No loudspeaker symbol appears in
the speedometer display.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. This will
deactivate the Distronic system.
Warning!
G
If the DTR warning lamp (red) E in the
speedometer dial comes on while driving
and/or an intermittent warning sounds, im-
mediate attention on the part of the driver is
required.
As required by the traffic situation, apply the
brakes and navigate around a possible ob-
stacle. However, do not drive by relying on
the distance warning function, as this will re-
sult in an emergency braking application.
Especially depending on road surface condi-
tions and driver reaction, this will not always
enable you to avoid a collision.
iComplex driving situations are not al-
ways fully recognized by Distronic. This
could result in wrong or missing dis-
tance warnings.
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 a dis-
tance set by Distronic). 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 could
lose sight of a vehicle traveling in front
of it. Your vehicle could then accelerate
to the previously selected speed.

Driving systems
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, Dis-
tronic will switch off, and the message Distronic Currently unavailable. See
Oper. Manual
appears in the multifunction
display.
For cleaning and care of the Distronic sen-
sor, see “Cleaning the Distronic* system
sensor cover” (page 325).Turns and bends
In turns or bends, Distronic may not detect
a moving vehicle in front, or it may detect
one too soon. This may cause your vehicle
to brake late or unexpectedly.
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 on the alert, ob-
serve all traffic and intercede as required by
steering or braking the vehicle.
Warning!
G
Distronic should not be used in snowy or icy
road conditions.
