WARNING Risk of an accident due to work
carried out incorrectly on the battery
Work carried out incorrectly on the battery
can, for example, lead to a short circuit. This
can restrict functions relevant for safety sys-
tems and impair the operating safety of your
vehicle.
You could lose control of the vehicle in the fol-
lowing situations in particular:
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
#
In the event of a short circuit or a similar
incident, contact a qualied specialist
workshop immediately.
#
Do not drive on.
#
Always have work on the battery carried
out at a qualied specialist workshop.

For safety reasons, Mercedes-Benz recommends
that you only use batteries which have been
approved for your vehicle by Mercedes-Benz.
All vehicles except vehicles with a lithium-ion bat-
tery
&
WARNING Risk of explosion due to elec-
trostatic charge
Electrostatic charge can ignite the highly
explosive gas mixture in the battery.
#
To discharge any electrostatic charge
that may have built up, touch the metal
vehicle body before handling the battery.
The highly ammable gas mixture is created while
the battery is charging and during starting assis-
tance.
&
WARNING Danger of chemical burns from
the battery acid
Battery acid is caustic.
#
Avoid contact with the skin, eyes or
clothing.

Notes on starting assistance and charging the 12
V battery
All vehicles
When charging the battery and during starting
assistance, always use the jump-start connection
point in the engine compartment.
*
NOTE Damage to the battery due to over-
voltage
When charging using a battery charger without
a maximum charging voltage, the battery or
the on-board electronics may be damaged.
#
Only use battery chargers with a maxi-
mum charging voltage of 14.8 V.

WARNING Risk of explosion due to the
ignition of hydrogen gas
If there is a short circuit or sparks are created,
there is a danger of hydrogen gas igniting
when you charge the battery.
#
Take care that the positive terminal of a
connected battery does not come into
contact with vehicle parts.
#
Never place metal objects or tools on a
battery.
#
When connecting and disconnecting the
battery, always observe the sequence of
battery terminals described.
#
During starting assistance, always take
care to connect only battery terminals of
identical polarity.
#
During starting assistance, observe the
sequence described for connecting and
disconnecting the jump leads.
#
Do not connect or disconnect the bat-
tery terminals with the engine running.
&
WARNING Risk of explosion due to explo-
sive mixture of gases
An explosive mixture of gases can escape
from the battery during charging and starting
assistance.
#
Fire, naked ames, smoking and creating
sparks must be avoided.
#
Make sure there is adequate ventilation.
#
Do not stand over the battery.
&
WARNING Risk of explosion from a frozen
battery
A discharged battery may freeze at tempera-
tures slightly above or below freezing point.
During starting assistance or battery charging,
battery gas can be released.
#
Always allow a battery to thaw before
charging it or performing starting assis-
tance.
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 vehi-
cle nor charge the battery.
The service life of a battery that has been thawed
may be reduced drastically. The starting behaviour
may deteriorate, particularly at low temperatures.
It is recommended that you have a thawed battery
checked at a qualied specialist workshop.
Plug-in hybrid
If your vehicle has been started with starting
assistance, it may not be possible to use the elec-
tric drive for approximately 30 minutes.
Starting assistance is not considered to be a nor-
mal operating condition.
All vehicles
*
NOTE Damage caused by numerous or
extended attempts to start the engine
Numerous or extended attempts to start the
engine may damage the catalytic converter
due to non-combusted fuel.
#
Avoid numerous and extended attempts
to start the engine.

cables with a sucient cross-section and
insulated terminal clamps.
R
Non-insulated parts of the terminal clamps
must not come into contact with other metal
parts while the jump leads/charging cables
are connected to the battery/jump-start con-
nection point.
R
The jump leads/charging cables must not
come into contact with any parts which may
move when the engine is running.
R
Always make sure that neither you nor the bat-
tery is electrostatically charged.
R
Keep away from re and naked ames.
R
Do not lean over the battery.
Observe the additional following points when
charging the battery:
R
Only use battery chargers tested and
approved for Mercedes-Benz.
R
Read the battery charger's operating instruc-
tions before charging the battery.
Observe the additional following points during
starting assistance:
R
Starting assistance may only be provided
using vehicles, batteries or other jump start
devices with a nominal voltage of 12 V.
R
The vehicles must not touch each other.
R
Vehicles with a petrol engine: jump-start the
vehicle only when the engine and exhaust sys-
tem are cold.

Replacing the 12 V battery
#
Observe the notes on the 12 V battery
(/ page 664).
Mercedes-Benz recommends that you have the
12 V battery replaced at a qualied specialist
workshop, e.g. at a Mercedes-Benz Service
Centre.
Observe the following notes if you want to replace
the battery yourself:
R
Always replace a faulty battery with a battery
which meets the specic vehicle require-
ments.
The vehicle is equipped with an AGM (Absorb-
ent Glass Mat) technology battery or a lithium-
ion battery. Full vehicle functionality is only
guaranteed with an AGM battery or lithium-ion
battery. For safety reasons, Mercedes-Benz
recommends that you only use batteries which
have been tested and approved for your vehi-
cle by Mercedes-Benz.
R
Use detachable parts such as vent hoses,
elbow ttings or terminal covers from the bat-
tery which is to be replaced.
R
Make sure that the vent hose is always con-
nected to the original opening on the side of
the battery.
Fit any existing or supplied cell caps.
Otherwise, gases or battery acid could
escape.
R
Make sure that detachable parts are recon-
nected in the same way.
Tow-starting or towing away
Overview of the permitted towing methods (not
plug-in hybrid)

NOTE Damage from automatic braking
If one of the following functions is activated,
the vehicle will brake automatically in certain
situations:
R
Active Brake Assist
R
Active Distance Assist DISTRONIC
R
HOLD function
R
Active Parking Assist
To avoid damaging the vehicle, deactivate
these systems e.g. during towing or in the car
wash.
Mercedes-Benz recommends transporting your
vehicle in the case of a breakdown, rather than
towing it away.
For towing with both axles on the ground, use a
tow rope or tow rod. Do not use tow bar systems.
*
NOTE Damage to the vehicle due to tow-
ing away incorrectly
#
Observe the instructions and notes on
towing away.
