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,
Distronic 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 301).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.
iIf the messageDistronic
Currently unavailable!
see oper. manualdisappears during driving and the last
speed stored flashes for approximately
five seconds, the dirt (e.g. slush) has
dissolved; Distronic works again.

232 Controls in detailDriving systemsOffset 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 its narrow profile, the vehicle
traveling near the edge of the roadway has
not yet been detected by Distronic. There
will be insufficient distance to the vehicle
ahead.

Driving systems
Parktronic (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 release the parking brake. 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 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 301).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers or the air
brakes of trucks) can cause the system to
send erratic indications, and should be tak-
en into consideration.
Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.

234 Controls in detailDriving systemsRange of the sensors
To function properly, the sensors must be
free of dirt, ice, snow and slush. Clean the
sensors regularly, being careful not to
scratch or damage the sensors.Front sensors
Rear sensors
Minimum distance
If the system encounters an obstacle in
this range, all the warning lamps come on
and you hear a warning signal. If the obsta-
cle is closer than the minimum distance,
the actual distance may no longer be indi-
cated by the system.

!During parking maneuvers, pay special
attention to objects located above or
below the height of the sensors (e.g.
planters or trailer hitches). The Parktro-
nic system will not detect such objects
at close range and damage to your ve-
hicle or the object may result.
Ultrasonic signals from outside sourc-
es (e.g. truck air brakes or jackham-
mers) may impair the operation of the
Parktronic system.

Driving systems
Warning indicators
Visual signals indicate to the driver the rel-
ative distance between the sensors and an
obstacle. The warning indicator for the
front area is located above the center air
vents in the dashboard. The warning indi-
cator for the rear area is integrated in the
rear dome lighting.Front area warning indicator1Left side of the vehicle
2Right side of the vehicleEach warning indicator is divided into six
yellow and two red segments for either
side of the vehicle. The Parktronic system
is ready when the border around the indi-
cator is illuminated.
The position of the gear selector lever de-
termines which warning indicators will be
activated.As your vehicle approaches an object, one
or more segments will come on, depending
on the distance. When the eighth segment
comes on, you have reached the minimum
distance.


Front area: An intermittent acoustic
warning will sound as the first red seg-
ment comes on and a constant acous-
tic warning lasting a maximum of three
seconds will sound for the second red
segment. The signal is canceled when
the gear selector lever is placed in
positionP.


Rear area: An intermittent acoustic
warning will sound as the first red seg-
ment comes on and a constant acous-
tic warning lasting a maximum of three
seconds will sound for the second red
segment. The signal is canceled when
the gear selector lever is placed in po-
sition D orP.
