General notes
Some systems perform a self test when the ignition is switched on. Some warning and indicator
lamps may temporarily switch on or flash during the test. This behaviour is nothing to be concerned about.
The warning and indicator lamps will alert you to a malfunction if they switch on or flash after the
drive system is started or while driving. Wa

If it is permitted by law to operate communica-
tions equipment while the vehicle is in motion,
you may only do so if the traffic situation per-
mits. You may otherwise be distracted from the
traffic conditions, cause an accident and injure
yourself and others.
Excessive levels of electromagnetic radiation
may cause damage to your health and to the
health of others. The use of an exterior aerial
takes into consideration the scientific discus-
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 vehicle
electronics and mobile phones is minimised
An exterior aerial has the following advantages:
R it conducts the electromagnetic fields gener-
ated 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 280).
General notes 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 Blue-
tooth ®
-capable mobile phones to
COMAND Online/Audio 20 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 226).
X Place the mobile phone bracket into the pre-
installed fitting; see the separate installation
instructions for the mobile phone fitting.
X Insert the mobile phone into the mobile phone
bracket; see the separate installation instruc- tions for the mobile phone fitting.
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 tele-
phone module into the pre-installed fitting. This connects it to the exterior aerial. If you wish to
charge the mobile phone, then you must con-
nect 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 181).
When you remove the key from the ignition lock, the mobile phone is disconnected from the vehi-cle. 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 transferred over to the mobile phone. It is then possible to
continue the conversation on the mobile phone. Features

Important safety notes
It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pres-
sure suitable for the operating situation
(Y page 269). Note that the correct tyre pres-
sure for the current operating situation must
first be taught-in to the tyre pressure monitor. If
there is a substantial loss of pressure, the warn-
ing threshold for the warning message is aligned to the reference values taught-in. Restart the
tyre pressure monitor after adjusting to the cold tyre pressure (Y page 272). The current pres-
sures are saved as new reference values. This
will ensure that a warning message will only
appear if the tyre pressure drops significantly.
The tyre pressure monitor does not warn you of
an incorrectly set tyre pressure. Observe the
notes on the recommended tyre pressure
(Y page 269).
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the tyre
is penetrated by a foreign object. In the event of a sudden loss of pressure, bring the vehicle to a
halt by braking carefully. Avoid abrupt steering
manoeuvres.
The tyre pressure monitor has a yellow warning lamp in the instrument cluster for indicating a
pressure loss or malfunction. Depending on how
the warning lamp flashes or lights up, a tyre
pressure that is too low or a malfunction in the
tyre pressure monitor is indicated:
R if the warning lamp is lit continuously, the tyre
pressure on one or more tyres is significantly
too low. The tyre pressure monitor is not mal-
functioning.
R if the warning lamp flashes for around a
minute and then remains lit constantly, the
tyre pressure monitor is malfunctioning.
In addition to the warning lamp, a message
appears in the multifunction display. Observe
the information on display messages
(Y page 209).
It may take up to ten minutes for a malfunction
of the tyre pressure monitor to be indicated. A
malfunction will be indicated by the tyre pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
fault has been rectified, the tyre pressure warn- ing lamp goes out after you have driven for a few
minutes.
The tyre pressure values indicated by the on-
board computer may differ from those meas-
ured at a filling station using a pressure gauge. The tyre pressures shown by the on-board com-
puter refer to those measured at sea level. At
high altitudes, the tyre pressure values indica-
ted by a pressure gauge are higher than those
shown by the on-board computer. In this case,
do not reduce the tyre pressures.
The operation of the tyre pressure monitor can
be affected by interference from radio transmit- ting equipment (e.g. radio headphones, two-way
radios) that may be being operated in or near the vehicle.

played for the position where the spare wheel is fitted is not the same as the current tyre pres-
sure of the emergency spare wheel.

Observe the instructions and safety notes in the display messages in the "Tyres" section
(Y page 209).
If the wheel positions on the vehicle are inter-
changed, the tyre pressures may be displayed
for the wrong positions for a short time. After a
few minutes of driving, this is rectified and the
tyre pressures are displayed for the correct
positions.
Restarting the tyre pressure monitor When you restart the tyre pressure monitor, all
existing warning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rently set tyre pressures as the reference values
for monitoring. In most cases, the tyre pressure monitor will automatically detect the new refer-
ence values after you have changed the tyre
pressure. However, you can also set reference
values manually as described here. The tyre
pressure monitor then monitors the new tyre
pressure values.
X Use the table on the inside of the charge
socket flap to ensure that the tyre pressure is
set correctly in all four tyres for the current
operating conditions.
Also observe the notes in the section on tyre
pressures (Y page 269).
X Make sure that the key is in position 2in the

Changing a wheel
Flat tyre
You can find information on what to do in the
event of a flat tyre in the "Breakdown assis-
tance" section (Y page 249). Information on
driving with MOExtended tyres in the event of a flat tyre can be found under "Breakdown assis-
tance" (Y page 250). Interchanging the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if the wheels or tyres have different dimensions.
The wheel brakes or suspension components may also be damaged. There is a risk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with a tyre pressure mon-
itor, electronic components are located in the wheel.
Tyre-fitting tools should not be applied in thearea of the valve, as this could damage the
electronic components.
Only have tyres changed at a qualified spe-
cialist workshop.
Interchanging the front and rear wheels of dif-
fering dimensions can render the general oper-
ating permit invalid.
Observe the instructions and safety notes in the "Changing a wheel" section (Y page 273).
The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear pat-
tern has formed on the tyres. Front tyres typi-
cally wear more on the shoulders and the rear
tyres in the centre.
On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time a wheel is
interchanged. Check the tyre pressure and reac-
tivate the tyre pressure monitor if necessary. Direction of rotation
Tyres with a specified direction of rotation have additional benefits, e.g. if there is a risk of aqua-
planing. These advantages can only be gained if the tyres are fitted corresponding to the direc-
tion of rotation.
An arrow on the sidewall of the tyre indicates its
correct direction of rotation. Changing a wheel
