Parktronic system* (Parking assist)
The Parktronic system is an electronic aid
with ultrasonic sensors. It is designed to
assist the driver during parking maneu-
vers. It visually and audibly indicates the
relative distance between the vehicle and
an obstacle.
The Parktronic system is automatically ac-
tivated when you switch on the ignition, re-
lease the parking brake, or place the gear
selector lever in position D, R, or N. The
Parktronic system deactivates at speeds
exceeding approximately 11 mph
(18 km/h). At lower vehicle speeds the
Parktronic system turns on again. 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 326).
Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. Other-
wise you run the risk of causing injury.!
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.

Driving systems
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 2 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
on/off
You can switch off the Parktronic system
manually.
The Parktronic switch is located in the low-
er part of the center console (

Have the Parktronic system checked
by an authorized Mercedes-Benz
Center as soon as possible.

The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and cel-
lular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the multifunction steering wheel. To

!
The initial activation of the Tele Aid system
may only be performed by completing the sub-
scriber agreement and placing an acquaintance
call using the ¡ button. Failure to complete
either of these steps will result in a system that
is not activated.
If you have any questions regarding activation,
please call the Response Center at
1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada).
