!
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.

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.

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.

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.
