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 (

Programming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:

Check the frequency of hand-held re-
mote control5 (typically located on
the reverse side of the remote). The in-
tegrated remote control is compatible
with radio-frequency devices operating
between 280-390 MHz.


Put a new battery in hand-held remote
control5. This will increase the likeli-
hood of the hand-held remote control
sending a faster and more accurate sig-
nal to the integrated remote control.


While performing step 3, hold
hand-held remote control5 at differ-
ent lengths and angles from the signal
transmitter button (2, 3 or4) you
are programming. Attempt varying an-
gles at the distance of 2 to 5 in
(5 to 12 cm) away or the same angle at
varying distances.


If another hand-held remote control is
available for the same device, try the
programming steps again using that
other hand-held remote control. Make
sure new batteries are in the hand-held
remote control before beginning the
procedure.


Straighten the antenna wire from the
garage door opener assembly. This
may help improve transmitting and/or
receiving signals.
i
Certain types of garage door openers are in-
compatible with the integrated remote control. If
you should experience further difficulties with
programming the integrated remote control,
contact an authorized Mercedes-Benz Center, or
call Mercedes-Benz Customer Assistance Cen-
ter (in the USA only) at 1-800-FOR-MERCedes, or
Customer Service (in Canada) at
1-800-387-0100.

610 OperationWinter drivingBefore the onset of winter, have your
vehicle winterized at an authorized
Mercedes-Benz Center. This service
includes:

Check of anticorrosion and antifreeze
concentration.


Addition of cleaning concentrate to the
water of the windshield and headlamp
cleaning system. Add MB Windshield
Washer Concentrate “MB Summerfit”
to a premixed windshield washer sol-
vent/antifreeze which is formulated for
below freezing temperatures
(page 772).


Battery test. Battery capacity drops
with decreasing ambient temperature.
A well charged battery helps to make
sure that the engine can be started,
even at low ambient temperatures.


Tire change.
Winter tires
Always use winter tires at temperatures
below 45°F (7°C) and whenever wintry
road conditions prevail. Not all M+S rated
tires provide special winter performance.
Make sure the tires you use show the
mountain/snowflake.marking on the
tire sidewall. These tires meet specific
snow traction performance requirements
of the Rubber Manufacturers Association
(RMA) and the Rubber Association of Can-
ada (RAC) and have been designed specif-
ically for use in snow conditions. Use of
winter tires is the only way to achieve the
maximum effectiveness of the ABS, EBP,
ESP
® and 4MATIC in winter operation.
For safe handling, make sure that all
mounted winter tires are of the same make
and have the same tread design.Always observe the speed rating of the
winter tires installed on your vehicle. If the
maximum speed for which your tires are
rated is below the speed rating of your
vehicle, you must place a notice to this
effect where it will be seen by the driver.
Such notices are available from your tire
dealer or from any authorized
Mercedes-Benz Center.
Warning!
G
Winter tires with a tread depth of less than 1/6in (4 mm) must be replaced. They are no
longer suitable for winter operation.

614 OperationMaintenance
Resetting the maintenance service indicator
In the event that the maintenance service
on your vehicle is not carried out by an au-
thorized Mercedes-Benz Center, you can
have the maintenance service indicator re-
set. The automotive maintenance facility
carrying out the maintenance service will
find the information for resetting the main-
tenance service indicator in the mainte-
nance-relevant information for your
vehicle. Such information is available from
any authorized Mercedes-Benz Center or
directly from Mercedes-Benz.
i
If the battery is disconnected, the days of
disconnection will not be included in the count
shown by the maintenance service indicator.
To arrive at the true maintenance service dead-
line, you will need to subtract these days from
the days shown in the maintenance service indi-
cator message or maintenance service indicator
display.
i
If the maintenance service indicator was in-
advertently reset, have an authorized
Mercedes-Benz Center correct it.
Only reset if the proper maintenance service has
been performed. Resetting the system without
performing the proper service as called for by
the maintenance service indicator will result in
engine damage and/or other vehicle damage not
covered by the Mercedes-Benz Limited
Warranty.
