Step on the brake pedal.
Distronic will be deactivated. The last

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.
The thumbwheel for making the time set-
ting is located on the lower section of the
center console.1Distance warning function on/off

Increasing distance
Increasing the distance setting tells
Distronic to maintain a greater following
distance to the vehicle ahead.

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 re-
duce vehicle speed further 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.

252 Controls in detailDriving systemsDecreasing distance
Decreasing the distance setting tells
Distronic to maintain a smaller following
distance to the vehicle ahead.
Turn thumbwheel3 towards®.
Distance warning function
When Distronic is deactivated, this func-
tion will continue to warn you when recog-
nizing a stationary obstacle or a slower
vehicle moving in the vehicle’s path and
the danger of a collision exists:


The distance warning lampl in the
instrument cluster comes on.


An intermittent warning will sound if
necessary.
If these warnings are issued, you must
brake manually to maintain a safe distance
and avoid a collision with the vehicle
ahead.
When 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.
Indicator lamp 2 on the switch comes
on. A loudspeaker symbol appears in
the multifunction display (

Deactivating

Press switch1.
Indicator lamp 2 on the switch goes
out. No loudspeaker symbol appears in
the multifunction display.
Warning!
G
If the distance warning lampl in the in-
strument cluster 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 pos-
sible obstacle. However, do not drive by re-
lying on the distance warning function, as
this will result in an emergency braking ap-
plication. Especially depending on road sur-
face conditions 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.

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.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

Currently unavailable
See Operator’s Manualappears in the multifunction display.
For cleaning and care of the Distronic sen-
sor, see “Cleaning the Distronic* system
sensor cover” (
page 366).
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, then your vehicle could 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 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.
iIf the message Distronic

speed stored flashes for approximately
5 seconds, the dirt (e.g. slush) has dis-
solved; Distronic works again.

254 Controls in detailDriving systemsTurns 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.Offset driving
A vehicle traveling in your lane but offset
from your direct line of travel may not be
detected by Distronic. There will be insuffi-
cient distance to the vehicle ahead.Lane changing
Distronic has not yet detected the vehicle
changing lanes. There will be insufficient
distance to the lane-changing vehicle.

255 Controls in detail

Narrow vehicles
Because of their narrow profile, the vehi-
cles traveling near the outer edges of the
lane have not yet been detected by Dis-
tronic. There will be insufficient distance to
the vehicles ahead.
Airmatic DC (Dual Control)*
Airmatic automatically selects the opti-
mum suspension tuning and ride height for
your vehicle. The Airmatic consists of two
components:

Adaptive Damping System (ADS)


Vehicle level control
The ADS automatically selects the opti-
mum damping for the respective driving
conditions. At the same time the suspen-
sion is set to either Sport 1, Sport 2 or
Comfort.Suspension tuning
The suspension tuning is set according to:


Your driving style


Road surface conditions


Your choice of suspension style,
Sport 1, Sport 2 or Comfort, which you
select using the damping button1
(page 256).
The following suspension styles are
available:

Your vehicle automatically adjusts its ride
height to


increase vehicle safety


reduce fuel consumption
The following vehicle chassis ride heights
can be selected:


Normal


Raised
The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed:


At a speed exceeding approximately
68 mph (110 km/h) with normal level
set or exceeding 75 mph (120 km/h)
with raised level set, the ride height is
reduced automatically. The table on
the next page provides an overview of
the vehicle levels.


With decreasing speed, the ride height
is again raised to the normal level.
!If you have selected the Comfort sus-
pension tuning, the vehicle lowers
slightly when you lock it within approx-
imately 60 seconds after switching off
the engine. When parking, make sure
that your vehicle cannot come into con-
tact with other objects, such as a curb,
while lowering. Your vehicle could oth-
erwise be damaged.iThe selected suspension style is stored
in memory, even after the SmartKey is
removed from the starter switch.
