with the climatic specifications of standard
EN 590 can help to prevent operating prob-
lems. If the ambient temperature is unusually
low or if you use fuel that has not been adap-
ted to the climatic specifications (e.g. diesel
fuel from the Mediterranean area), the flow
properties of the fuel may be inadequate.
Flow improver
Flow improvers can be added to improve the
cold resistance of diesel fuel. The effective-
ness of a flow improver is not guaranteed with
every fuel.
Correct dosage and thorough mixing are deci-
sive factors in ensuring improvement in low-
temperature resistance. Under certain cir-
cumstances, an excessive dosage may
actually decrease low-temperature resist-
ance and should therefore be avoided (follow
the manufacturer'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. Engine compartment
Bonnet
G
Risk of accident
Do not pull the release lever while the vehicle
is in motion. The bonnet may otherwise open
and block your view.
Active bonnet (pedestrian protection) The active bonnet can reduce the risk of injury
to pedestrians in certain accident situations.
Raising the bonnet increases the clearance to hard components, such as the engine. Fur-
ther information about the active bonnet
(Y
page 302).
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 Operating
Instructions 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.
Keep away from the area of rotation of the fan
blades. Otherwise you could be injured.
Vehicles with a petrol engine:
The electronic ignition system uses high volt-
age. For this reason, you must never touch the
ignition system components (ignition coil,
ignition cable, spark plug connector or test
socket) while:
R the engine is running
R the engine is being started
R the ignition is switched on and the engine
is being cranked by hand
You could otherwise receive an electric shock
and be severely or fatally injured.
Vehicles with a diesel engine:
the electronic injector control operates at
high voltage. For this reason, you must never
touch injection system components while:
R the engine is running
R the engine is being started
R the ignition is switched on
You could otherwise receive an electric shock
and be severely or fatally injured. Engine compartment

not properly engaged. Open it again and
close it with a little more force. Engine oil
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).
Depending on the engine, the oil dipstick may
be installed at a different location. 220

Driving tips
R
Maintain a greater distance from the vehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then, increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from a standstill refer to sea
level. When driving in mountainous areas,
note that the power output of the engine,
and consequently the vehicle's gradient-
climbing capability, decrease with increas-
ing altitude.
If the trailer swings from side to side:
X Do not accelerate.
X Do not counter-steer.
X Brake if necessary. G
Risk of accident
On no account should you attempt to draw the
vehicle/trailer combination out by increasing
speed. Folding in the ball coupling
i Fold the ball coupling back in if you are
not using the trailer tow hitch. G
Risk of injury
Make sure that no persons or animals are in
the pivoting range of the ball coupling. Other-
wise, they could be injured.
X Place the protective cap on the ball cou-
pling.

Battery acid is caustic.
Avoid contact with the skin,
eyes or clothing.
Wear suitable protective
clothing, in particular
gloves, an apron and a face
mask.
Immediately rinse acid
splashes off with clean
water. Consult a doctor if
necessary.
Wear eye protection.
Keep children away.
Observe this Owner's Man-
ual.
H
Environmental note
Do not dispose of batteries in the household
rubbish. Dispose of defective batteries in an
environmentally responsible manner. Take
them to a Mercedes-Benz Service Centre or
to a special collection point for old batteries. G
Risk of injury
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide
increased impact protection to prevent vehi-
cle occupants from suffering acid burns
should the battery be damaged in the event
of an accident.
To prevent acid burns, observe the following
safety notes when handling batteries:
R do not lean over the battery.
R do not place any metal objects on a battery.
Otherwise, you could cause a short circuit
and the battery's gas mixture could ignite. R
make sure that you do not create an elec-
trostatic charge, e.g. by wearing synthetic
clothing or as a result of friction on fabrics.
Therefore, you should not pull or slide the
battery over carpets or other synthetic
materials.
R never touch the battery first. To discharge
a possible electrostatic charge, step out of
the vehicle first and touch the bodywork.
R do not wipe the battery using a cloth. The
battery may explode as a result of electro-
static charge or due to flying sparks.
! Before loosening the terminal clamps of
the battery, switch off the engine and
remove the key or, on vehicles with KEY-
LESS GO*, make sure that the ignition is
not switched on. In the instrument cluster,
all of the indicator lamps must be out. Oth-
erwise, you may destroy electronic compo-
nents, such as the alternator.
i Mercedes-Benz recommends that you
have work involving the battery, e.g.
removal, charging and replacement, car-
ried out at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
Installation location of the battery Saloon
Depending on its engine type, your vehicle is
equipped with a battery in the engine com-
partment or boot/luggage compartment. It is
located in front of the bulkhead on the right-
hand side or in the spare wheel well on the320
