Briefly press button1 to change from
normal level to raised level. When vehi-
cle is at raised level, pressing the but-
ton will return the vehicle to normal
level.
When raised level is set, indicator
lamp2 in the button comes on.
When normal level is set, indicator
lamp2 in the button goes out.
iAt a speed of approximately above 75 mph
(120 km/h) or if the speed amounts to between
50 mph (80 km/h) and 75 mph (120 km/h) for
approximately 5 minutes, the setting raised is
canceled. Indicator lamp2 in the button goes
out.
If you do not drive in this speed range, the raised
level remains stored even if the SmartKey is re-
moved from the starter switch.

Driving systems
Parktronic 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
activated when you switch on the ignition,
release the parking brake, 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 or depress the parking brake
pedal.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 337).
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 remains 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,
especially at times of snow and ice, see
“Cleaning the Parktronic* system sensors”
(
page 337).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers, car wash or
the air brakes of trucks) can cause the sys-
tem 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.

Front sensors
Rear sensorsMinimum 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 might no
longer be indicated by the system.

Cornersapprox. 32 in (80 cm)
!During parking maneuvers, pay special at-
tention 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 sources (e.g.
truck air brakes, car wash or jackhammers) may
impair the operation of the Parktronic 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 indicator
1Left side of the vehicle
2Right side of the vehicle
3Readiness indicatorsEach warning indicator is divided into five
yellow and two red segments for either
side of the vehicle. The Parktronic system
is operational when yellow readiness
indicators3 are illuminated.
The position of the gear selector lever
determines 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 seventh seg-
ment illuminates, you have reached the
minimum distance.

Front area: An intermittent acoustic
warning will sound as the first red
distance segment illuminates and a
constant acoustic warning lasting a
maximum of 2 seconds will sound for
the second red distance segment. The
signal is canceled when the gear selec-
tor lever is placed in positionP or the
parking brake is activated.

Rear area: An intermittent acoustic
warning will sound as the first red
distance segment illuminates and a
constant acoustic warning lasting a
maximum of 2 seconds will sound for
the second red distance segment. The
signal is canceled when the gear selec-
tor lever is placed in positionD, P or
the parking brake is activated.Gear selector

The Parktronic system can be switched off
manually.
The Parktronic switch is located in the low-
er part of the center console (

Parktronic system malfunction
If only the red distance segments illumi-
nates and an acoustic warning sounds,
there is a malfunction in the Parktronic
system. The Parktronic system will auto-
matically switch off after 20 seconds and
the indicator 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-
nates 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 seconds and the indicator lamp in the
Parktronic switch comes on.
Switch off the ignition (page 38).

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

Loading
Roof rack*
1Trim
Open trim1 at the trim strips in the
roof.
Secure the roof rack according to
manufacturer’s instructions for instal-
lation.
Loading instructions
The total load weight including vehicle
occupants and luggage/cargo should not
exceed the total load limit indicated on the
corresponding placard located on the driv-
er’s door B-pillar.
The handling characteristics of a fully load-
ed vehicle depend greatly on the load dis-
tribution. It is therefore recommended to
load the vehicle according to the illustra-
tions shown, with the heaviest items being
placed towards the front of the vehicle.
Always place items being carried against
front or rear seat backrests, and fasten
them as securely as possible.
The heaviest portion of the cargo should
always be kept as low as possible since it
influences the handling characteristics of
the vehicle.
Warning!G
Only use roof racks approved by
Mercedes-Benz for your vehicle model to
avoid damage to the vehicle.
Follow the manufacturer’s installation
instructions. Otherwise, an improperly at-
tached roof rack system or its load could be-
come detached from the vehicle.
Do not exceed the maximum roof load of
220 lb (100 kg).
Take into consideration that when the roof
rack is loaded, the handling characteristics
are different from those when operating the
vehicles without the roof rack loaded.
!Load the roof rack in such a way that the ve-
hicle cannot be damaged while driving.
Make sure

you can fully raise the tilt/sliding sunroof

you can fully open the trunk

Pull catches2 in direction of arrows.
Open the cover1 downwards in direc-
tion of the arrow.1Hook and loop fastener
Unfasten hook and loop fastener1.
Pull ski bag into passenger compart-
ment and unfold.
Open the front storage compartment in
the rear center console (
page 247).
Remove the cup holder (page 247).
Warning!G
Always fasten items being carried as secure-
ly as possible fastening materials appropri-
ate for the weight and size of the load.
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.
