478 Controls in detailDriving systemsPark Assist is automatically activated
when the engine is running and the trans-
mission is in drive position D, reverse
gearR or neutral positionN.
The Park Assist system deactivates at
speeds over approximately 10 mph
(16 km/h). At lower speeds the Parktronic
system turns on again.
Park Assist is also switched off when you
set the automatic transmission to P or
switch off the engine.
While the transmission is in neutral
positionN, Park Assist is switched off if
you secure the vehicle in place with the
electronic parking brake.
The Park Assist system monitors the sur-
roundings of your vehicle with four sensors
in the front bumper and two sensors in the
rear bumper.Range of the sensors
The sensors of the Park Assist system are
integrated in the front and rear bumpers.
Make sure that the bumpers are clear of
dirt, ice and slush in the area of the sen-
sors, as otherwise, Park Assist may not
function properly, see “Cleaning the driv-
ing systems sensors” (
page 620).

Power outlet
The power outlet is located in the rear cen-
ter console.
Switch on the ignition (
page 370).
Flip up cover1 and insert electrical
plug (cigarette lighter type).
Floormats*
!
The lighter socket can be used to accommo-
date 12V DC electrical accessories (up to a max-
imum 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 con-
necting and disconnecting, or using plugs that do
not fit properly) can damage the lighter socket.
With the socket damaged, 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 connecting 12V DC elec-
trical accessories designed for use with a stan-
dard “cigarette lighter” plug type.
i
Operation of the rear door lighters is only
possible, if the override switch (
page 64) is de-
activated.
i
If the engine is off and the cigarette lighter is
being used extensively, the vehicle battery may
become discharged.
i
The power outlet can be used to
accommodate 12V DC electrical accessories
(e.g. air pump, auxiliary lamps) up to a maximum
of 180 W.
If the engine is off and the outlet is being used
extensively, the vehicle battery may become dis-
charged.
Warning!
G
Whenever you are using floormats, make
sure there is enough clearance and that the
floormats are securely fastened.
Floormats should always be securely fas-
tened using the eyelets and the retainer
pins.
Before driving off, check that the floormats
are securely in place and adjust them if nec-
essary. A loose floormat could slip and
hinder proper functioning of the pedals.
Do not place several floormats on top of
each other as this may impair pedal move-
ment.i
To install or remove the floormat more easi-
ly, move the driver’s seat or front passenger seat
as far to the rear as possible (
page 373).

Passenger compartmentDriving abroad
Abroad, there is an extensive
Mercedes-Benz service network at your
disposal. If you plan to drive into areas
which are not listed in the index of your
Mercedes-Benz Center directory, you
should request pertinent information from
an authorized Mercedes-Benz Center.Control and operation of radio
transmitters
COMAND, radio, and telephone*Telephones and two-way radios
Radio transmitters, such as a portable tele-
phone or a citizens band unit should only
be used inside the vehicle if they are con-
nected to an antenna that is installed on
the outside of the vehicle.
Refer to the radio transmitter operation in-
structions regarding use of an external an-
tenna.
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 cause injury
to vehicle occupants unless the items are
securely fastened in the vehicle.
The trunk is the preferred place to carry ob-
jects.
Warning!
G
Please do not forget that your primary re-
sponsibility is to drive the vehicle safely.
Only operate the COMAND (Cockpit Man-
agement and Data System), radio, or tele-
phone
1 if road, weather and traffic
conditions permit. Otherwise, you may not
be able to observe traffic conditions and
could endanger yourself and others.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
1Observe all legal requirements.
Warning!
G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or
personal injury.
