ton and thumbwheel for setting distance
are located on the lower part of the front
center console.
1Distance warning function on/off but-
ton
2Thumbwheel for setting distanceIncreasing distance
Increasing the distance setting tells
Distronic to maintain a greater following
distance to the vehicle ahead.

Turn thumbwheel2 towards¯.
Decreasing distance
Decreasing the distance setting tells
Distronic to maintain a shorter following
distance to the vehicle ahead.

Turn thumbwheel2 towards®.Distance warning function
When Distronic is deactivated, this func-
tion will continue to warn you when recog-
nizing 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 sounds.
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 stops. The warning sound also
stops when the distance to the vehicle
ahead is sufficient again without applying
the brake pedal. In this case the distance
warning lampl also extinguishes.

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 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.
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.


218 Controls in detailDriving 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,
Distronic will switch off, and the message DISTRONIC CURRENTLY UNAVAILABLE SEE
OPERATORS MANUAL
appears in the multi-
function display.
For cleaning and care of the Distronic sen-
sor, see “Cleaning the Distronic* system
sensor cover” (
page 322).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.
iIf the message
DISTRONIC CURRENTLY
UNAVAILABLE SEE OPERATORS MANUAL
disappears during driving and the last
speed stored flashes for approximately
5 seconds, the dirt (e.g. slush) has dis-
solved; Distronic is again operational.

Driving systems
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.Narrow vehicles
Because of their narrow profiles, the vehi-
cles traveling near the outer edges of the
lane have not yet been detected by
Distronic. There will be insufficient dis-
tance to the vehicles ahead.

lowered according to the selected level
setting and to the vehicle speed:


With increasing speed, ride height is re-
duced by up to approximately 0.95 in

With decreasing speed, the ride height
is again raised to the selected vehicle
level.Select the level 1 and 2 settings only when

Parktronic system* (Parking assist)
The Parktronic system is an electronic aid
designed to assist the driver during park-
ing maneuvers. It visually and audibly indi-
cates the relative distance between the
vehicle and an obstacle.
The Parktronic system is automatically ac-
tivated when you switch on the ignition
and placed the gear selector lever in posi-
tion D, R, or N.
The Parktronic system deactivates at
speeds over approximately 11 mph
(18 km/h). At lower speeds the Parktronic
system turns on again.
The Parktronic system also deactivates
when you place the gear selector lever in
position P.The Parktronic system monitors the sur-
roundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
1Sensors in the front bumperWarning!
G
Parktronic is a supplemental system. It is
not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always rests with the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Parktronic
system can be affected by dirty sensors, es-
pecially at times of snow and ice, see
“Cleaning the Parktronic* system sensors”
(page 322).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers, car wash,
or the air brakes of trucks) can cause the
system to send erratic indications, and
should be taken into consideration.
Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.
