G
Risk of accident
Observe the legal requirements of the country
in which you are currently driving regarding
operating mobile communications equipment
in a vehicle.
If it is permitted by law to operate communi-
cations equipment while the vehicle is in
motion, you may only do so when the traffic
situation allows. Otherwise, you could be dis-
tracted from the traffic conditions, cause an
accident and injure yourself and others.
Two-way radios and fax equipment used with-
out low-reflection exterior aerials can inter-
fere with the vehicle's electronics and,
thereby, jeopardise the operating safety of
the vehicle and your safety. Therefore, you
must only use this equipment if it is correctly
connected to a separate, reflection-free, exte-
rior aerial. G
Risk of injury
Excessive electromagnetic radiation may
cause damage to your health and the health
of others. Using an exterior aerial takes into
account current scientific discussions relat-
ing to the possible health risk posed by elec-
tromagnetic fields.
To ensure optimum reception quality for
mobile phones in the vehicle, and to minimise
mutual influences between the vehicle elec-
tronics and mobile phones, Mercedes-Benz
recommends the use of an approved exterior
aerial. An exterior aerial conducts the elec-
tromagnetic fields generated by a wireless
device to the exterior of the vehicle; the field
strength within the vehicle interior is lower
than in a vehicle that does not have an exte-
rior aerial.

cases, these are country-specific. You can
obtain these mobile phone brackets from a
qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
The functions and services available when
you use the phone depend on your mobile
phone model and service provider.
Inserting the mobile phone
X Open the telephone compartment
(Y page 153).
X Place the mobile phone bracket into the
pre-installed fitting; see the separate
mobile phone bracket fitting instructions.
X Insert the mobile phone into the mobile
phone bracket; see the separate mobile
phone bracket fitting instructions.
If the mobile phone is inserted in the mobile
phone bracket, you can speak to the person
you are calling using the hands-free system.
You can operate the telephone using the
6 and~ buttons on the multi-function
steering wheel. You can operate other mobile
phone functions via the on-board computer
(Y page 111).
When you take the key out of the ignition lock,
the mobile phone stays on but you can no
longer use the hands-free system.
If you are making a call and you would like to
take the key out of the ignition lock, first
remove the mobile phone from the bracket.
Otherwise, the call will be ended. Garage door opener*

DIN 51628 German standard can lead to
increased wear, engine damage and dam-
age to the exhaust system.
Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not add such fuels to diesel fuel and do
not use any special additives (exception:
flow improvers – see "Low outside temper-
atures").
Damage caused by the use of unapproved
fuels or additives is not covered by the
implied warranty.
Further information on "Fuel" (Y page 287).
Low outside temperatures The flow properties of diesel may be inade-
quate at low ambient temperatures.
Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, various climate-dependent low-tem-
perature classes are defined in EN 590. Using
diesel fuels which meet the climatic require-
ments set out in EN 590 can help avoid oper-
ating problems. The flow properties of diesel
fuel may be inadequate at unusually low out-
side temperatures or when using fuel which
has not been adjusted to climatic conditions
(e.g. diesel fuels from Mediterranean
regions).
Flow improver
Flow improvers may be added to improve low-
temperature resistance. The effectiveness of
a flow improver is not guaranteed with every
fuel.
Correct dosage and mixing are decisive fac-
tors in ensuring improvement in low-temper- ature resistance. Under certain circumstan-
ces, an excessive dosage may actually
decrease low-temperature resistance, and
should therefore be avoided (follow the man-
ufacturer's dosing instructions).
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Otherwise, malfunctions
can only be rectified by heating the entire fuel
system, e.g. by parking the vehicle in a heated
garage.
Observe the information provided by the man-
ufacturer when using a flow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz. You can obtain
further information from any Mercedes-Benz
Service Centre.

Depending on driving style, the vehicle con-
sumes up to 0.8 l oil per 1,000 km. The oil
consumption may be higher than this when
the vehicle is new or if you frequently drive at
high engine speeds.
Checking the engine oil level Before checking the engine oil level the fol-
lowing conditions for the vehicle should be
met:
R the vehicle should be parked on level
ground.
R the engine should be switched off for at
least five minutes if the engine is at normal
operating temperature.
R the engine should be switched off for at
least 30 minutes if the engine is not at
operating temperature (i.e. if you only start
the engine briefly).

If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that
monitor the tyre pressures in all four tyres.
The tyre pressure monitor warns you when
the pressure drops in one or more of the
tyres. The tyre pressure monitor only func-
tions if the correct wheel electronics units are
fitted to all wheels. G
Risk of accident
The tyre pressure monitor does not warn you
of an incorrectly set tyre pressure. The table
on the inside of the fuel filler flap will help you
decide whether the tyre pressures should be
corrected.
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. Do not
make any sudden steering movements when
doing so.
i The operation of the tyre pressure moni-
tor can be affected by interference from
radio transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.

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 currently set tyre pressures as the speci-
fied values for monitoring.
