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 326).

!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 dam-
age 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.

Minimum distance
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.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 trim.
Front area warning indicator1Left side of the vehicle
2Right side of the vehicleEach 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.

226 Controls in detailDriving systemsAs 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 distance segment. The sig-
nal is canceled when the gear selector
lever is placed in position P or the park-
ing brake is set.
Rear area: An intermittent acoustic
warning will sound when the first dis-
tance segment illuminates. This signal
quickens with each additional distance
segment lit. When the eighth distance
segment illuminates, the acoustic
warning becomes a constant signal.
The signal is canceled when the gear
selector lever is placed in positionD
orP or the parking brake is set.Switching the Parktronic system

Parktronic system malfunction
If only the red distance segments illumi-
nate and a warning sounds, there is a mal-
function 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 warning sounds, the Parktron-
ic system sensors are dirty or there is an
interference from other radio or ultrasonic
signals. The Parktronic system will auto-
matically switch off after 20 seconds and
the indicator lamp in the Parktronic switch
comes on.
Switch off the ignition.
Clean Parktronic system sensors
(page 326).
Switch on the ignition (
page 36).
or
Check the Parktronic system operation
at another location to rule out interfer-
ence from outside radio or ultrasonic
signals.

Warning!
G
To help avoid personal injury during a colli-
sion or sudden maneuver, exercise care
when storing objects in the vehicle. Put lug-
gage or cargo in the trunk if possible. Do not
pile luggage or cargo higher than the seat
backs. Do not place anything on shelf be-
hind roll bar.
Parcel nets cannot secure hard or heavy ob-
jects.
Keep compartment lids closed. This will help
to prevent stored objects from being thrown
about and injuring vehicle occupants during
an accident.

Warning!
G
The parcel net is intended for storing
light-weight items only.
Heavy objects, objects with sharp edges or
fragile objects may not be transported in the
parcel net. In an accident, during hard brak-
ing, or sudden maneuvers, they could be
thrown around inside the vehicle and cause
injury to vehicle occupants.
The parcel net cannot protect transported
goods in the event of an accident.
Warning!
G
Secure all pieces of luggage in the rear with
the luggage straps. Unsecured pieces of lug-
gage can otherwise cause injury during a
braking maneuver and can increase the risk
of injury in an accident.
Never allow anyone to ride in the rear.
The luggage straps can only secure light lug-
gage items. Carry heavy pieces of luggage in
the trunk.
The rear compartment area is not designed
or intended to accommodate occupants. Se-
vere personal injury or death may be the re-
sult in an accident.
