Problems with the seat heating
Problem
Possible causes/consequences and
M
MSolutions The seat heating has
switched off prema-
turely or cannot be
switched on. The on-board voltage is too low because too many electrical con-
sumers are switched on.
X Switch off electrical consumers that you do not need, such as
the rear window heating or interior lighting.
Once the battery is sufficiently charged, the seat heating can be
switched back on manually. Switching the seat ventilation on/off
Front seats The three blue indicator lamps in the buttons
indicate the blower setting you have selected.
X Turn the key to position 1or 2in the ignition
lock (Y page 159).
X To switch on: press button:repeatedly
until the desired blower setting is set.
X To switch off: press button:repeatedly
until all the indicator lamps go out.
i If the battery voltage is too low, the seat
ventilation may switch off.
i You can open the side windows using the
"Convenience opening" feature
(Y page 100). The seat ventilation of the
driver's seat automatically switches to the
highest level.
i When the vehicle is stationary, the fan
speed can be reduced automatically. This
reduces the noises of the seat ventilation. Seats

When the auxiliary heating is switched on,
make sure that:
R no flammable materials come into contact
with hot vehicle components
R the exhaust gas can escape from the
exhaust pipe unhindered
R the exhaust gas does not come into contact
with flammable materials.
The auxiliary heating and the exhaust gas out-
let are situated behind the right-hand front
wheel.
! Operating the auxiliary heating/ventila-
tion draws on the vehicle battery. After you
have heated or ventilated the vehicle a
maximum of two times, drive for a longer
distance.
Switch the auxiliary heating on regularly once
a month for about ten minutes.
The auxiliary heating heats the air in the vehi-
cle interior to the set temperature. This
occurs without using the heat of the running
engine. The auxiliary heating is operated
directly using the vehicle's fuel. For this rea-
son, the tank content must be at least at
reserve fuel level to ensure that the auxiliary
heating functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux- iliary heating could switch from ventilation
mode to heating mode or from heating mode to ventilation mode.
The auxiliary heating switches off when the
engine is switched off. The auxiliary ventila-
tion switches off when you turn the key to key
position 2(Y page 159).
The auxiliary heating switches off automati-
cally after 30 minutes. This time limit can be
altered. To do this, visit a qualified specialist
workshop.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature. Before switching on X
Turn the key to position 2in the ignition
lock (Y page 159).
X Set the desired temperature using the
w rocker switch on the front control unit
or using COMAND Online (see the separate operating instructions).
If you do not alter the temperature before
switching on the auxiliary heating, the last
temperature setting will be adopted.
Auxiliary heating or ventilation can also be
switched on if the manually set climate con-
trol is activated. Optimum comfort can be
attained when the system is set to automatic
mode. Set the temperature to 22 †.
You can activate or deactivate the auxiliary
heating/ventilation:
R using the rocker switch on the centre con-
sole (Y page 149)
R using the remote control (Y page 150)
The on-board computer can be used to spec- ify up to three departure times, one of which
may be preselected:
R using the remote control (Y page 150)
R using COMAND Online (see the separate
operating instructions)
Switching the auxiliary heating/venti-
lation on/off using the centre console
rocker switch The colours of the indicator lamps on the
rocker switch have the following meanings:
Blue Auxiliary ventilation switched on
Red Auxiliary heating switched on

X
To switch the auxiliary heating/ventila-
tion on: press rocker switch :up or down.
The red or the blue indicator lamp in rocker
switch :lights up.
X To set the temperature: switch on auxili-
ary heating/ventilation.
COMAND Online is activated for approx-
imately one minute.
X Set the desired temperature using
COMAND Online (see the separate operat-
ing instructions).
In addition you can adjust the temperature at any time using COMAND Online if the auxili-
ary heating/ventilation is switched on. To do
so, call up COMAND Online using the qbut-
ton on the centre console.
X To switch the auxiliary heating/ventila-
tion off: press rocker switch :up or
down.
The red or the blue indicator lamp in rocker
switch :goes out.
Switching the auxiliary heating/venti-
lation on/off using the remote control General notes
Your vehicle comes with one remote control.
You may use two additional remote controls
for your vehicle. For more information, please contact a qualified specialist workshop.
Store the remote control for the auxiliary
heating so that the auxiliary heating cannot
be switched on unintentionally. In particular,
ensure that the remote control for the auxili- ary heating is kept out of the reach of chil-
dren.
The remote control has a range of approx-
imately 300 metres. This range is reduced by:
R sources of radio interference
R solid objects between the remote control
and the vehicle
R the remote control being in an unfavoura-
ble position in relation to the vehicle
R transmitting from an enclosed space
i The optimum range can be achieved if you
hold the remote control vertically, pointing
upwards when you press one of the but-
tons.
If the remote control battery is low, the bat-
tery symbol on the left of the display is shown as empty. Replace the remote control battery and observe the important safety notes when
doing so (Y page 152).

sion surrounding the possible health risk
posed by electromagnetic fields.
Mercedes-Benz recommends the use of an
approved exterior aerial. This ensures:
R optimal mobile phone reception quality in
the vehicle
R that mutual interference between the vehi-
cle electronics and mobile phones is mini-
mised
An exterior aerial has the following advan-
tages:
R it conducts the electromagnetic fields gen-
erated by a wireless device to the exterior
R the field strength in the vehicle interior is
lower than in a vehicle that does not have
an exterior aerial
Information on retrofitting two-way radios
and mobile phones (RF transmitters)
(Y page 400).
General notes Depending on the vehicle equipment, there
are various mobile phone brackets that may
be fitted in your vehicle; in some cases, these
are country-specific.
More information on suitable mobile phones,
mobile phone brackets and on connecting
Bluetooth ®
-capable mobile phones with
COMAND Online can be obtained:
R at your Mercedes-Benz Service Centre
R on the Internet at http://www.mercedes-
benz.com/connect
The functions and services available when
you use the phone depend on your mobile
phone model and service provider.
Using a mobile phone To connect a mobile phone to the exterior
aerial and charge it, insert it into the mobile
phone bracket. X
Open the telephone compartment
(Y page 316).
X Place the mobile phone bracket into the
pre-installed fitting; see the separate instal-
lation instructions for the mobile phone fit-
ting.
X Insert the mobile phone into the mobile
phone bracket; see the separate installa-
tion instructions for the mobile phone fit-
ting.
i The mobile phone can also be operated
without being in the bracket. However, the charging function and aerial function are
not available.
In order to use Bluetooth ®
(SAP profile) on
your telephone module, you must first insert
the telephone module into the pre-installed
fitting. This connects it to the exterior aerial.
If you wish to charge the mobile phone, then
you must connect it to a USB port.
Further information on the telephone module
with Bluetooth ®
(SAP profile) can be found in
the Digital Owner's Manual.
Operating the mobile phone You can operate the telephone using the
6 and~ buttons on the multifunction
steering wheel. You can operate other mobile
phone functions via the on-board computer
(Y page 254).
When you remove the key from the ignition
lock, the mobile phone is disconnected from
the vehicle. You can then no longer make calls using the hands-free system.
If a call is active and you remove the key from the ignition lock, the conversation is trans-
ferred over to the mobile telephone. It is then
possible to continue the conversation on the
mobile telephone. Features
