ave work on the batteries carried
out at aqualified specialist workshop. Should
it, in exceptional circumstances, be abso-
lutely necessary to disconnect the 12-volt
battery yourself, please observe the follow-
ing:
R secure the vehicle to prevent it from rolling
away.
R switch the ignition off.
R first, disconnect the negative terminal, fol-
lowed by the positive terminal.
Vehicles with automatic transmission: the
transmission is locked in position Pafter dis-
connecting the battery.
After the work has been completed, firmly
reinstall the battery and the cover of the pos-
itive terminal.
Comply with safety precautions and take pro-
tective measures when handling batteries. Risk of explosion
Fire, naked flames and smoking are
prohibited when handling the bat-
tery. Avoid creating sparks.
Electrolyte or battery acid is corro-
sive. Avoid contact with the skin,
eyes or clothing.
Wear suitablep rotective clothing, in
particular gloves, an apron and a
face mask.
Immediately rinse electrolyte or acid
splashes off with clean water. Con-
sult adoctor if necessary. Wear eye protection.
Keep children away.
Observe this Owner's Manual. For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz.T
hese batteries provide
increased impact protection to prevent vehicle
occupants from suffering acid burns should the battery be damaged in the event of an accident.
In order for the battery to achieve the maximum possible service life, it must always be suffi-
ciently charged.
Like other batteries, the vehicle battery may
discharge over time if you do not use the vehicle.In such cases, have the battery disconnected ataq ualified specialist workshop. You can also
charge the battery with acharger recommended
by Mercedes-Benz.F or more information,
please contact aqualified specialist workshop.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for alengthy
period. Consult aqualified specialist workshop
if you wish to leave your vehicle parked up for a
long period of time.
When you park the vehicle, remove the key if you do not require any electrical consumers. The
vehicle will then use very little energy, thus con- serving battery power. Charging the 12
Vbattery
Vehicles with alithium-ion battery:
! Only use battery chargers with
amaximum
charging voltage of 14.4 V.
All other vehicles G
WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a risk of an explosion.
Particularlya void fire, naked flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over abattery. G
WARNING
Battery acid is caustic. There is arisk of injury.
Avoid contact with the skin, eyes or clothing.
Do not breathe in any battery gases. Do not
lean over the battery. Keep the batteries out Battery (vehicle)

General notes When handling engine oil, observe the important
safety notes on service products (Y page 371).
The quality of the engine oil is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Benz approves
engine oils that correspond to the current tech-
nical standard.
Therefore, only Mercedes-Benz approved
engine oils may be used in Mercedes-Benz
engines.
Further information on tested and approved
engine oils can be obtained from any Mercedes-
Benz Service Centre. Mercedes-Benz recom-
mends that you have the oil change carried out
at aq ualifieds pecialist workshop. Mercedes-
Benz approval is indicated on the oil container
by the inscription "MB-Freigabe" or "MB-
Approval "and the corresponding designation,
e.g. MB-Freigabe or MB-Approval 229.51. You can call up an overview of approved engine
oils on the Internet at
http://bevo.mercedes-benz.com by entering
the designation, e.g. 229.5.
The table shows which engine oils have been
approved for yourv ehicle.
Petrol engines: in certain countries, different
engine oils can be used,p rovidedthat the main-
tenance intervals are reduced .For more infor-
mation, please contact aqualifieds pecialist

Importan tsafety notes G
WARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is arisk of fire and injury.
Let the engine cool dow nbefore yo utop up
the antifreeze .Make sur ethat antifreeze is
not spilled next to the filler neck. Thoroughly clea
nthe antifreeze from components before
starting the engine.
! Only ad
dcoolant that has bee npremixed
with the desire dantifreeze protection. You

! Always use
asuitabl ecoolant mixture, even
in countries where hig htemperatures prevail.
Otherwise ,the engine cooling system is not
sufficiently protected from corrosion and
overheating.
i Have the coolant regularly replaced at a
qualified specialist workshop and the replace- ment confirmed in the Service Booklet.
Comply with the important safety precautions
for service products whe nhandling coolant
(Y page 371).
The coolant is amixture of water and anti-
freeze/corrosion inhibitor. It is responsible for
the following:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
If antifreeze/corrosion inhibito rispresent in the
correct concentration, the boiling point of the
coolant during operation will be approximately
130 †.
The antifreeze concentrate/corrosion inhibitor
concentration in the engine cooling system
should:
R be at least 50%. Thi swillp rotect the engine
cooling system against freezing dow nto
approximatel y-37 †.
R not excee d55% (antifreeze protection down
to -45 †). Hea twillo therwise not be dissipa-
