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.

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

of the reach of children. Immediately rinse off
battery acid thoroughly with plenty of clean
water and seek medical attention at once. G
WARNING
Ad ischarged battery can freeze at tempera-
tures below freezin gpoint. When jump-start-
ing the vehicle or charging the battery, gases can escape from the battery. There is arisk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
! Only use battery chargers with
amaximum
charging voltage of 14.8 V.
All vehicles:
! Only charge the battery using the jump-start
connection point.
The jump-starting connection point is in the
engine compartment (Y page 345).
X Open the bonnet.
X Connect the battery charger to the positive
terminal and earth point in the same order as
when connectingt he donor battery in the
jump-starting procedure (Y page 345).
Keep away from fire and naked flames. Do not
lean over the battery. Never charge the battery
if it is still fitted to the vehicle, unless you use a battery charger which has been tested and
approved by Mercedes-Benz. Abattery charger
unit specially adapted for Mercedes-Benz vehi-
cles and tested and approved by Mercedes-
Benz is available as an accessory. This device
permits charging of the battery in position. Con-
tact aMercedes-Benz Service Centre for infor-
mation and availability. Read the battery charg-
er's operating instructions before charging the
battery.
All vehicles except vehicles with alithium-
ion battery: if the indicator/warning lamps in
the instrument cluster do not light up at low
temperatures, it is very likely that the dis-
charged battery has frozen .Inthis case you may
neither jump-start the vehicle nor charge the
battery. The service life of abattery that has
been thawed may be reduced. The starting char-
acteristics may be impaired, especially at low
temperatures. Have the thawed battery
checked at aqualified specialist workshop. Vehicles with
alithium-ion battery: at low
temperatures, do not charge abattery which has
been removed using abattery charger. Allow the
battery to warm up gently first, if necessary.
Otherwise, the service life can be shortened and the starting characteristics impaired, especially
at low temperatures. 344
