218 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 release the parking brake. The Park-
tronic system deactivates at speeds
exceeding 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
can be affected by dirty sensors, especially
at times of snow and ice, see “Cleaning the
Parktronic* system sensors” (
page 285).
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 that no persons or animals are in
the area in which you are maneuvering. You
could otherwise injure them.

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.Front sensors
Rear sensorsMinimum distance
If the system detects an obstacle in this
range, all the warning lamps light up and
you hear a warning signal. If the obstacle is
closer than the minimum distance, the ac-
tual distance might no longer be indicated
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 Park-
tronic system will not detect such ob-
jects at close range and damage to
your vehicle 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.

220 Controls in detailDriving systemsWarning indicators
Visual signals indicate to the driver the rel-
ative distance between the sensors and an
obstacle. The warning indicators for the
front area are located in the dashboard
(page 20). The warning indicator for the
rear area is integrated in the rear trim.
1Left front area warning indicator2Right front area warning indicator
Each 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 light up, depending
on the distance between your vehicle and
the object. When the eighth segment lights
up, you have reached the minimum dis-
tance.
Front area: An intermittent acoustic
warning will sound as the first red seg-
ment lights up and a constant acoustic
warning, both lasting a maximum of
three seconds, will sound for the eighth
segment, i.e. the second red segment.
Rear area: An intermittent acoustic
warning will sound as the first red seg-
ment lights up and a constant acoustic
warning, both lasting a maximum of
three seconds, will sound for the eighth
segment, i.e. the second red segment.
The signal is canceled when the selec-
tor lever is placed in position D orP.Switching the Parktronic system
on/off
You can switch off the Parktronic system
manually.
The Parktronic switch is located in the up-
per section of the center console.

Open trim at the trim strips in the roof.
Secure the roof rack according to man-
ufacturer’s instructions for installation.
Loading instructions
The total load weight including vehicle oc-
cupants and luggage/cargo should not ex-
ceed the vehicle capacity weight indicated
on the certification tag which can be found
on the left door pillar.
Warning!
G
Use only roof racks approved by Mer-
cedes-Benz for your vehicle model to avoid
damage to the vehicle. Follow manufactur-
er’s installation instructions.
!Load the roof rack in such a way that
the vehicle cannot be damaged while
driving.

Loading
Cargo tie-down hooks
Six hooks are located in the trunk.
Carefully secure cargo by applying
even load on all hooks with rope of suf-
ficient strength to hold down the cargo.
Warning!
G
Always fasten items being carried as secure-
ly as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.
To help avoid personal injury during a colli-
sion or sudden maneuver, exercise care
when transporting cargo. Put luggage or car-
go in the trunk if possible. Do not pile lug-
gage or cargo higher than the seat backs.
Do not place anything on the rear-window
shelf.
Never drive vehicle with trunk open. Deadly
carbon monoxide (CO) gases may enter ve-
hicle interior resulting in unconsciousness
and death.
