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 insuffi-
cient 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 this winter diesel at temper-
atures of -5 °C or below.
You can use this winter diesel at tempera-
tures down to about -20 °C without problems.
If only summer diesel fuel or less cold-resist-
ant winter diesel fuel (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
insufficient. Otherwise, malfunctions
can only be rectified by heating the entire fuel
system, e.g. by parking the vehicle in a heated
garage. G
Risk of fire
Do not use petrol to refuel vehicles with a
diesel
engine. Never mix diesel with petrol.
This would damage the fuel system and
engine and could result in a vehicle fire.
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. Information about flow
improvers that have been tested and
approved by Mercedes-Benz can be obtained
from any Mercedes-Benz Service Centre. Engine compartment
Bonnet

Risk of accident
Do not pull the release lever while the vehi-
cle is in motion. The bonnet could other-
wise open.
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 Man-
ual 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 turning area of the fan. You could
otherwise sustain an injury.

approved by Mercedes-Benz. Mixing oils reduces the benefits of high-
grade engine oil.
! Do
not use lubricant additives, since they
lead to increased wear and damage to the
mechanical assemblies. The use of lubri- cant additives will result in a restriction of
your warranty.
! Engine oils for vehicles without a diesel
particle
filter may also be used temporarily
in vehicles with a diesel particle filter if the
engine oil listed is not available. You must
then have an oil change carried out as soon
as possible.
