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
G
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.

Engine compartment
195Engine oil
Depending on how it is driven, the vehicle
consumes a maximum of 0.8 l oil per 1,000
km. The oil consumption may be higher than
this when the vehicle is new or if you fre-
quently drive at high engine speeds. You can
only estimate the oil consumption after you
have driven a considerable distance.
You will find further information about engine
oil in the "Technical data" section
(Y page 314).
Checking the engine oil level To do so:
R
the vehicle should be parked on level
ground
R the engine should be switched off for at
least five minutes if the engine was at nor-
mal operating temperature
R the engine should be switched off for at
least 30 minutes if the engine was not at
operating temperature (i.e. if you only star-
ted the engine briefly) Using the oil dipstick
Example of a vehicle with a petrol engine (CLS 350)

3 Lower mark
X Pull oil dipstick 1 out of the oil dipstick
tube.
X Wipe off oil dipstick 1.
X Insert oil dipstick 1 into the oil dipstick
tube to the stop, and take it out again.
The oil level is correct if the level is between
lower mark 3 and upper mark 2.
X Top up the oil if necessary ( Y page 195).i
The difference in quantity between lower
mark 3 and upper mark 2 is approxi-
mately 2 litres.

X Unscrew cap 1 and remove it.
X Top up by the amount of oil required.
! Do not add too much oil. If too much oil
is added, there is a risk of damage to the
engine or the catalytic converter.
X Screw cap 1 onto the filler neck.
H Environmental note
When topping up the oil, take care not to
spill any. Oil must not be allowed to escape
into the soil or waterways. You would oth-
erwise be damaging the environment.
Coolant
G Risk of injury
The cooling system is pressurised. There-
fore, only unscrew the cap once the engine
has cooled down. The coolant temperature
gauge must display less than 70°C. You
could otherwise be scalded by escaping hot
coolant.
Coolant consists of water and antifreeze/cor-
rosion inhibitor. Only check the coolant level
when the vehicle is on a level surface and the
engine has cooled down. Checking the coolant levelThe expansion tank is located in the engine
compartment on the left when viewed in the
direction of travel.

Notes on care
Regular and proper care maintains the value
of your vehicle.
i It
is advisable to use Mercedes-Benz care
products.
Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-
cialist workshop immediately, e.g. a
Mercedes-Benz Service Centre.
Repair damage caused by loose chippings
and remove the following substances imme-
diately, whilst avoiding rubbing too hard:
R Soak insect remains with insect remover
and rinse off afterwards.
R Soak bird droppings with water and rinse
off afterwards.
R Remove tree resin, oils, fuels and grease by
rubbing gently with a cloth soaked in clean-
ing or lighter fluid.
R Use silicone remover to remove wax.
R Use tar remover to remove tar stains. H
Environmental note
Dispose of empty packaging, cleaning
cloths and polishing wads in an environ-
mentally responsible manner.
! Do not affix:
R stickers
R films
R magnetic plates or similar
to painted surfaces, otherwise you could
damage the paintwork. Vehicle care
!

Do not park the vehicle for a long period
of time directly after cleaning, especially if
the wheels have just been cleaned with a
wheel cleaner. Wheel cleaners could cause
rapid corrosion of the brake discs and
brake pads/linings. After cleaning, park
the vehicle when it is at normal operating
temperature. Operation

Service products and capacities
316 Coolant
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
i When the vehicle is first delivered, it is
topped up with a coolant that will ensure
adequate antifreeze and corrosion protec-
tion.
! Only top up with coolant that has been
premixed
with the desired quantity of anti-
freeze protection. You could otherwise
damage the engine.
There is more information about coolant
and topping it up on Mercedes-Benz Spec-
ifications for Service Products Sheet
310.1.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the cooling system will not be
sufficiently protected from corrosion, and
the boiling point will be too low. If antifreeze/corrosion inhibitor is present in
the
correct concentration, the boiling point of
the coolant will be around 130 °C.
The antifreeze/corrosion inhibitor concentra-
tion in the cooling system should:
R be at least 50%. This will protect the cooling
system against freezing down to around –
37 °C.
R not exceed 55% concentration (antifreeze
protection down to –45 °C), otherwise heat
will not be effectively dissipated.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor-
rosion inhibitor. Mercedes-Benz recom-
mends using an antifreeze/corrosion inhibi-
tor which has been approved for Mercedes-
Benz.
! The cooling system contains a lifetime
supply which must be renewed after 15
years, or after 250, 000 km at the latest.
Have the renewal confirmed in the Service
Booklet.
The warranty is only valid if you top up with
an antifreeze/corrosion inhibitor which
has been approved by Mercedes-Benz. Technical data

Brake fluid
Over a period of time, the brake fluid absorbs
moisture from the air; this lowers its boiling
point. G
Risk of accident
If the boiling point of the brake fluid is too
low,
vapour pockets may form in the brake
system when the brakes are applied hard
(e.g. when driving downhill). This would
impair braking efficiency. Have the brake fluid renewed every two
years with a brake fluid that has been
approved by Mercedes-Benz and have this
confirmed in the Service Booklet.
i There is usually a notice in the engine
compartment

to remind you when the next
brake fluid change is due. Windscreen washer system
The washer fluid reservoir holds approxi-
mately 4.5 litres; on vehicles with the head-
lamp cleaning system* it holds 7 litres.
The headlamp cleaning system*
and the
windscreen washer system are both supplied
from the washer fluid reservoir.
