indicator MERCEDES-BENZ C-Class 2011 W204 Manual PDF

The 115 V AC power socket : provides an
alternating voltage of 115 V, so that small
electronic devices can be connected. These
devices, such as games consoles, chargers
and laptops, should not consume more than
a maximum of 150 W altogether.
Requirements for operation of these devices:
R 12 V power sockets in the footwell of the
second row of seats and in the stowage
compartment must be functioning
correctly ( Y page 224).
R the plug of the electronic device is plugged
into the 115 V power socket :.
R the on-board voltage is within a permissible
voltage range.
R the maximum wattage of the device to be
connected must not exceed 150 W.
XOpen flap =.XInsert the plug of the electrical device into
the 115 V power socket :.
Indicator lamp ; lights up.
If indicator lamp ; does not light up, please
read the chapter on malfunctions.
XTo turn off: disconnect the plug from the
115 V power socket :.
Ensure that you do not pull on the cord.XClose flap =.Possible causes of malfunction:
R the on-board voltage of the vehicle is not
within the permissible voltage range.
R the temperature of the DC/AC converter is
momentarily too high.
R some small electronic devices have a
constant nominal power of less than
150 W, but a very high inrush current.
These devices will not work. If you connect
such a device, the 115 V power socket :
will not supply it with power.
If indicator lamp ; still does not light up,
consult a specialist workshop, e.g. an
authorized Mercedes-Benz Center.

Notes on programming the remote
control
Canadian radio frequency laws require
transmitter signals to "time-out" (or quit) after
several seconds of transmission. This may
Features233Loading, stowing and featuresBA 204 USA, CA Edition A 2011; 1; 5, en-UShereepeVersion: 3.0.3.62010-05-20T09:17:30+02:00 - Seite 233Z

not be long enough for the integrated signal
transmitter to pick up the signal during
programming. Similar to this Canadian law,
some U.S. gate operators are designed to
"time-out" in the same manner.
If you live in Canada or have difficulties
programming the garage door opener
(regardless of where you live) when using the
programming steps (see above), proceed as
follows:XPress transmitter button ( ;, = or ?) and
hold it down during the following steps until
the setup has been completed
successfully.XAt the same time, press transmitter button
B of the garage door remote control for
two seconds, then release it for two
seconds, then press it again for two
seconds.XRepeat this sequence on transmitter
button B of the garage door remote
control until the frequency signal has been
learned.XIf the setup procedure is successful,
indicator lamp : flashes once slowly and
goes out after a few seconds.XContinue with the other programming
steps (see above).
Problems when programming
If you have problems when programming the
integrated remote control, please note the
following:
R check the transmitter frequency of garage
door remote control A (which can usually
be found on the rear of the remote control).
The integrated remote control is
compatible with equipment that operates
in the frequency range 280 to 390 MHz.
R replace the batteries in garage door remote
control A. This increases the likelihood of
garage door remote control A sending a
strong and precise signal to the integrated
remote control on the rear-view mirror.
R When aiming the garage door remote
control at the transmitter buttons on the
rear-view mirror, hold garage door remote
control A at differing distances and angles
from the transmitter button that you are
programming. Try different angles from a
distance of 2 to 12 inches (5 to 30 cm) or
the same angle from differing distances.
R If there is another garage door remote
control for the same device, perform the
programming steps again using the remote
control. Before performing these steps,
make sure that new batteries have been
installed in the garage door remote control.
R Align the antenna cable of the garage door
opener unit. This can improve signal
reception/transmission.
Opening or closing the garage door
Once programmed, the integrated remote
control will assume the function of the garage
door system's remote control. Please also
read the operating instructions for the garage
door system.
XTurn the SmartKey to position 2 in the

overhead control panel that you have
programmed to operate the garage door.

Vehicle equipment
iThis manual describes all the standard
and optional equipment of your vehicle
which was available at the time of
purchase. Country-specific differences are
possible. Bear in mind that your vehicle
may not feature all functions described
here. This also refers to safety-related
systems and functions.
Engine compartment
Hood
Opening the hood
GWarning
Do not pull the release lever while the vehicle
is in motion. Otherwise, the hood could be
forced open by passing air flow.
This could cause the hood to come loose and
injure you and/or others.
GWarning
Do not open the hood when the engine is
overheated. You could be seriously injured.
Observe the coolant temperature gauge to
determine whether the engine may be
overheated. If you see flames or smoke
coming from the engine compartment, move
away from the vehicle. Wait until the engine
has cooled. If necessary, call the fire
department.
GWarning
There is a risk of injury if the hood is open,
even if the engine is not running.
Some engine components can become very
hot.
To avoid the risk of burns, only touch those
components described in the Operator's
Manual and observe the relevant safety notes.
GWarning
To help prevent personal injury, stay clear of
moving parts when the hood is open and the
engine is running.
The radiator fan may continue to run for
approximately 30 seconds or may even
restart after the engine has been turned off.
Stay clear of fan blades.
GWarning
The engine is equipped with a transistorized
ignition system. Because of the high voltage,
it is dangerous to touch any components
(ignition coils, spark plug sockets, diagnostic
socket) of the ignition system:
Rwith the engine running
Rwhile starting the engine
Rwhen the ignition is switched on and the
engine is turned manually
XMake sure that the windshield wipers are
switched off.
GWarning
The windshield wipers and wiper linkage
could be set in motion.
When the hood is open, you or others could
be injured by the wiper linkage.
Make sure that the windshield wipers are
switched off. Remove the SmartKey or make
sure that no ignition position has been
selected with KEYLESS-GO. All indicator
lamps must be off in the instrument cluster.
