12 V battery - important safety notes
PLUG-IN HYBRID vehicles are equipped with a 12 V battery and a high-voltage battery. The
following notes refer to the 12 V battery.
Notes on the high-voltage battery can be
obtained in the "High-voltage battery – impor-
tant safety notes" section (Y page 440).
Work on the battery, e.g. removing or fitting,
requires specialist knowledge and the use of
special tools. Therefore, always have work on the battery carried out at a qualified specialist
workshop. G
WARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can lead to function restrictions applying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-lock braking system) or the
ESP ®
(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted. You could lose control of the vehicle, for
example:
R when braking
R in the event of abrupt steering manoeuvres
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar inci-
dent, contact a qualified specialist workshop
immediately. Do not drive any further. Always have work on the battery carried out at a
qualified specialist workshop.
Further information about ABS (Y page 79)
and ESP ®
(Y page 84).
All vehicles except vehicles with a lith-
ium-ion battery: G
WARNING
Electrostatic build-up can lead to the creation of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle body to remove any existing electrostatic
build-up.
The highly flammable gas mixture is created
while the battery is charging and when jump-
starting.
Always make sure that neither you nor the
battery is electrostatically charged. Electro-
static charge is created, for example:
R by wearing synthetic fibre clothing
R by friction between clothing and the seat
R when you pull or push the battery across
carpet or other synthetic materials
R when you rub the battery with a cloth G
WARNING
During the charging process, a battery produ- ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion. 438

R
Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts.
R Never place metal objects or tools on a bat-
tery.
R It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected.
R It is particularly important to observe the
described order when connecting and dis-
connecting the jump leads.
R Never connect or disconnect the battery
terminals while the engine is running. G
WARNING
Battery acid is caustic. There is a risk 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
of the reach of children. Immediately rinse off
battery acid thoroughly with plenty of clean
water and seek medical attention at once.

Environmental note Batteries contain pollutants.
It is illegal to dispose of them with the household rubbish.
They must be collected sep-
arately and disposed of in anenvironmentally responsible
recycling system. Dispose of batteries in an
environmentally responsible
manner. Take discharged
batteries to a qualified spe-
cialist workshop or to a col-
lection point for used batter-
ies.
! Have the battery checked regularly at a
qualified specialist workshop. Observe the service intervals in the Service
Booklet or contact a qualified specialist
workshop for more information.
! Always have work on the batteries carried
out at a qualified specialist workshop.
Should it, in exceptional circumstances, be absolutely necessary to disconnect the 12-
volt battery yourself, please observe the
following:
R secure the vehicle to prevent it from roll-
ing away.
R switch off the engine and remove the
key. Make sure the ignition is switched
off. Check that all the indicator lamps in
the instrument cluster are off. Otherwise,
you may damage electronic components such as the alternator, for example.
R first, disconnect the negative terminal
clamp, followed by the positive terminal
clamp. Never swap the terminal clamps.
The vehicle electronics may otherwise be
damaged.
R the transmission is locked in position P
after disconnecting the battery. The vehi-
cle is secured against rolling away. You
can then no longer move the vehicle.
The batteries and the covers of the positive
terminal clamps must always be fitted
securely during operation.
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
battery. Avoid creating sparks.
Electrolyte or battery acid is corro-
sive. Avoid contact with the skin,
eyes or clothing.
Wear suitable protective clothing,
in particular gloves, an apron and a face mask. Battery (vehicle)
439Breakdown assistance Z

Avoid contact with the skin, eyes or clothing.
Immediately rinse electrolyte splashes off
with water and seek medical attention
straight away.
! Exhaustive discharge caused by the vehi-
cle standing idle for lengthy periods can
damage the high-voltage battery. If the
vehicle is idle for lengthy periods leave the
high-voltage battery connected to a charg-
ing station.
Consult a Mercedes-Benz Service Centre if
you wish to leave your vehicle parked up for a
long period of time. Charging the 12 V battery
Vehicles with a lithium-ion battery:
! Only use battery chargers with a maxi-
mum charging voltage of 14.4 V.
All ot her vehicles G
WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a risk of an explosion.
Particularly avoid fire, naked flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery. G
WARNING
Battery acid is caustic. There is a risk 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
of the reach of children. Immediately rinse off
battery acid thoroughly with plenty of clean
water and seek medical attention at once. G
WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases can escape from the battery. There is a risk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
! Only use battery chargers with a maxi-
mum charging voltage of 14.8 V.
All ve hicles:
! Only charge the battery using the jump-
start connection point.
The jump-starting connection point is in the
engine compartment (Y page 443).
X Open the bonnet.
X Connect the battery charger to the positive
terminal and earth point in the same order
as when connecting the donor battery in
the jump-starting procedure (Y page 443).
Keep away from fire and open flames. Do not lean over the battery. Never charge the bat-
tery if it is still fitted to the vehicle, unless you
use a battery charger which has been tested
and approved by Mercedes-Benz. A battery
charger unit specially adapted for Mercedes- Benz vehicles and tested and approved by
Mercedes-Benz is available as an accessory.
This device permits charging of the battery in
position. Contact a Mercedes-Benz Service
Centre for information and availability. Read
the battery charger's operating instructions
before charging the battery.
All vehicles except vehicles with a lith-
ium-ion battery: if the indicator/warning
lamps in the instrument cluster do not light up at low temperatures, it is very likely that the
discharged battery has frozen. In this case
you may neither jump-start the vehicle nor
charge the battery. The service life of a bat-
tery that has been thawed may be reduced.
The starting characteristics may be impaired,
especially at low temperatures. Have the
thawed battery checked at a qualified spe-
cialist workshop.
Vehicles with a lithium-ion battery: at low
temperatures, do not charge a battery which
has been removed using a battery charger. Battery (vehicle)
