Remove your foot from the accelerator
pedal.
The selected speed appears in the multi-
function display for approximately five sec-
onds, and the corresponding speedometer
segments from the selected speed to the
vehicle maximum speed are illuminated
(
page 256).
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.

260 Controls in detailDriving systemsParktronic 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
positionD,R,orN.
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
positionP.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 bumper
Range 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, see
“Cleaning the Parktronic system* sensors”
(
page 350).
Warning!
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 350).
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.

If the system detects an obstacle in this
range, all the distance warning segments
illuminate and you hear a warning signal. If
the obstacle is closer than the minimum
distance, the actual distance may no long-
er be indicated by the system.Center

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

262 Controls in detailDriving systemsWarning 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.
1Left side of the vehicle
2Right side of the vehicle
Each warning indicator is divided into six
yellow and two red distance segments for
either side of the vehicle. The Parktronic
system is ready when the border around
the indicator 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 distance segments will illuminate,
depending on the distance. When the
eighth distance segment illuminates, you
have reached the minimum distance.


Front area: An intermittent acoustic
warning will sound as the first red dis-
tance segment illuminates and a con-
stant acoustic warning lasting a
maximum of two seconds will sound for
the second red distance segment. The
signal is canceled when the gear selec-
tor lever is placed in positionP.


Rear area: An intermittent acoustic
warning will sound as the first red dis-
tance segment illuminates and a con-
stant acoustic warning lasting a
maximum of two seconds will sound for
the second red distance segment. The
signal is canceled when the gear selec-
tor lever is placed in position DorP.

Parktronic system malfunction
If only the red distance segments illumi-
nate and a acoustic warning sounds, there
is a malfunction in the Parktronic system.
The Parktronic system will automatically
switch off after 20 seconds and the indica-
tor lamp in the Parktronic switch comes
on.

Have the Parktronic system checked
by an authorized Mercedes-Benz
Center as soon as possible.If only the red distance segments illumi-
nate and no acoustic warning sounds, the
Parktronic system sensors are dirty or
there is an interference from other radio or
ultrasonic signals. The Parktronic system
will automatically switch off after 20 sec-
onds and the indicator lamp in the Park-
tronic switch comes on.

Switch off the ignition.

Clean the Parktronic system sensors
(page 350).

Switch on the ignition.
or

Check the Parktronic system operation
at another location to rule out interfer-
ence from outside radio or ultrasonic
signals.

switched on when the ignition is
switched on (
