Driving systems
Parktronic system (Parking assist)*, Canada only
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
(
page 34) 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
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*
(Canada only) sensors” (
page 369).
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.

270 Controls in detailDriving systemsRange 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*
(Canada only) sensors” (
page 369).
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 may no long-
er 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
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.

Loading
Loading instructions
The total load weight including vehicle oc-
cupants and luggage/cargo should not ex-
ceed the load limit or vehicle capacity
weight indicated on the corresponding
placard located on the driver’s door B-pillar
(page 333).
The handling characteristics of a fully load-
ed vehicle depend greatly on the load dis-
tribution. It is therefore recommended to
load the heaviest items being placed to-
wards the front of the vehicle.
Always place items being carried against
rear seat backrests, and fasten them as se-
curely as possible.
The heaviest portion of the cargo should al-
ways be kept as low as possible since it in-
fluences the handling characteristics of
the vehicle.
!To prevent damage to the soft top or
luggage/cargo when lowering the roof:
load trunk only to the height of the
luggage cover
do not permit luggage/cargo to
push up the closed luggage cover
do not place anything on the shelf
behind the roll bar
do not place anything on the soft
top compartment cover
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.
Never drive vehicle with trunk open. Deadly
carbon monoxide (CO) gases may enter ve-
hicle interior resulting in unconsciousness
and death.

Cup holdersWarning!
G
In order to help prevent spilling liquids on
vehicle occupants and/or vehicle equip-
ment, only use containers that fit into the
cup holder. Use lids on open containers and
do not fill containers to a height where the
contents, especially hot liquids, could spill
during braking, vehicle maneuvers, or in an
accident. Liquids spilled on vehicle occu-
pants may cause serious personal injury.
Liquids spilled on vehicle equipment may
cause damage not covered by the
Mercedes-Benz Limited Warranty
When not in use, keep the cup holder
closed. An open cup holder may cause injury
to you and others when contacted during
braking, vehicle maneuvers, or in an
accident.

!The lighter socket can accommodate
12V DC electrical accessories (up to a
maximum of 85 W) designed for use
with the standard “cigarette lighter”
plug type. Keep in mind, however, that
connecting accessories to the lighter
socket (for example extensive connect-
ing and disconnecting, or using plugs
that do not fit properly) can damage the
lighter socket. With the socket dam-
aged, the lighter may no longer be able
to be placed in the heating (pushed-in)
position, or the lighter may pop out too
early with the lighter not hot enough.
To help avoid damaging the cigarette
lighter socket, we recommend con-
necting 12V DC electrical accessories
designed for use with the standard
“cigarette lighter” plug type to the 12V
power outlet (
page 287) in your vehi-
cle whenever possible.
iThe power outlet can be used to
accommodate electrical consumers
(e.g. air pump, auxiliary lamps) up to a
maximum of 180 W.

The Tele Aid system consists of three
types of response:
automatic and manual emergency
roadside assistance and
informationThe Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and
cellular 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
raise, press buttonæ and to lower,
press buttonç. The volume can also be
adjusted using the volume knob on your
audio system or COMAND* head unit.
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.
!The initial activation of the Tele Aid
system may only be performed by
completing the subscriber 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).
iThe SOS button is located above the
interior rear view mirror.
The Roadside Assistance button•
and the Information button¡ are
located below the center armrest
cover.

Programming the integrated remote
control
Step 1:
Switch on the ignition (
page 36).
Step 2:
If you have previously programmed an
signal transmitter button and wish to
retain its programming, proceed to
step 3.
If you are programming the integrated
remote control for the first time, press
and hold the two outer signal transmit-
ter buttons2 and4 and release
them only when the indicator lamp1
begins to flash after approximately
20 seconds (do not hold the button for
longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory.
Warning!
G
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent po-
tential harm or damage. When programming
a garage door opener, the door moves up or
down. When programming a gate operator,
the gate opens or closes.
Do not use the integrated remote control
with any garage door opener that lacks
safety stop and reverse features as required
by U.S. federal safety standards (this
includes any garage door opener model
manufactured before April 1, 1982).
A garage door that cannot detect an object
- signaling the door to stop and reverse -
does not meet current U.S. federal safety
standards.
When programming a garage door opener,
park the vehicle outside the garage.
Do not run the engine while programming
the integrated remote control. Inhalation of
exhaust gas is hazardous to your health. All
exhaust gas contains carbon monoxide, and
inhaling it can cause unconsciousness and
possible death.
