Risk of accident
Clear all windows of ice or snow before setting
off. Otherwise, impaired visibility could
endanger you and others.
i The rear window heating has a high cur-
rent draw. You should therefore switch it
off as soon as the window is clear, as it only
switches off automatically after several
minutes.

Risk of accident
Only switch over to air-recirculation mode
briefly at low outside temperatures. Other-
wise, the windows could mist up, thus impair-
ing visibility and endangering yourself and
others. This may prevent you from observing

General notes
G
Risk of injury
Make sure that nobody can become trapped
when closing the sliding sunroof. If there is a
risk of entrapment, release the switch and
push it briefly in any direction to stop the slid-
ing sunroof. G
Risk of injury
Children could injure themselves if they oper-
ate the sliding sunroof.
Never leave children unsupervised in the vehi-
cle. Always take the key with you when leaving
the vehicle, even if you are only leaving it for
a short time. G
Risk of injury
The glass in the panorama sunroof could
break in an accident. If you are not wearing a
seat belt, there is a risk that you could be
thrown through the opening in the event of the
vehicle overturning. Therefore, always wear a
seat belt to reduce the risk of injuries.
! Only open the panorama sliding sunroof
if it is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding sunroof. The seals could otherwise
be damaged.
i When the sliding sunroof is open, apart
from the normal airflow noises resonance
noises may also occur. They are caused by minor pressure fluctuations in the vehicle
interior. Change the position of the sliding
sunroof or open a side window slightly to
reduce or eliminate these noises.

Loading guidelines
The handling characteristics of a laden vehi-
cle depend on the distribution of the load
within the vehicle. You should therefore load
your vehicle as shown in the illustrations. Observe the following notes when transport-
ing a load:
R
when transporting a load, never exceed the
maximum permissible gross vehicle weight
or the permissible axle loads for the vehicle
(including occupants).
R position heavy loads as far forwards and as
low down in the luggage compartment as
possible.
R the load must not protrude above the upper
edge of the backrests.
R always place the load against the front or
rear seat backrests.
R always place the load behind unoccupied
seats if possible.
R secure the load with sufficiently strong and
wear-resistant load restraints. Pad sharp
edges for protection. Stowage compartments

Risk of injury

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.
i
There are various mobile phone brackets
that may be fitted to your vehicle; in some
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 130).
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 com-
puter (Y page 99).
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. 140 FeaturesControls

!
In countries in which diesel with a higher
sulphur content is available (e.g. 0.035 per-
cent by weight), the engine oil should be
renewed at more frequent intervals. More
information about intervals for changing
the engine oil can be obtained from any
Mercedes-Benz Service Centre.
! The use of fuels which do not meet the
requirements of EN 590 or German stand-
ard DIN 51628 can cause increased wear,
and damage the engine and 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 war-
ranty.
Further information on "Fuel" (Y page 245) .
Low outside temperatures The flow properties of diesel may be inade-
quate at low ambient temperatures.
To prevent operating problems, diesel fuel
with improved cold flow qualities is available
during the winter months. Your vehicle must
be refuelled with winter diesel at tempera-
tures of – 5 † or below.
You can use winter diesel at temperatures
down to about – 20 †without any problems.
If only "summer diesel" or less cold-resistant
"winter diesel" (e.g. in Mediterranean
regions) is available, you should add an amount of flow improver to the fuel corre-
sponding to the outside temperature.
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.
Flow improver
The effectiveness of a flow improver is not
guaranteed with every fuel. Observe the infor-
mation provided by the manufacturer when
using a flow improver. Only use flow improv-
ers that have been tested and approved by
Mercedes-Benz. You can obtain further infor-
mation from any Mercedes-Benz Service
Centre. Engine compartment
Bonnet
G
Risk of accident
Do not pull the release lever while the vehicle
is in motion. If you do so, the bonnet may open
up and block your view.
Opening G
Risk of injury
There is a risk of injury if the bonnet 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 Owner’s Manual
and observe the relevant safety notes. G
Risk of injury
The radiator fan between the radiator and the
engine can start automatically, even if the key
has been removed from the ignition lock. For
this reason, you must not reach into the fan
rotation area. Otherwise, you could be
injured. 146 Engine compartmentOperation

R the engine is being started.
R the ignition is switched on and the engine
is being cranked by hand.
You could otherwise suffer an electric shock
