e service. Observe the notes on charging the high-voltage
batt

ery ( page 166). Risk of explosion.
Fire, naked
Oames and smoking ar
e
prohibited when handling the battery.
Avoid creating sparks. Electrolyte or battery acid is corrosive.
A

void contact with the skin, eyes or

Notes on starting assistance and charging the 12
V batt

ery All vehicles
When c

harging the battery and during starting
assistance, always use the jump-start connection
point in the engine compartment. *
NOTE Damag
e to the battery due to over-
voltage When charging using a battery charger without
a maximum c
harging voltage, the battery or
the on-board electronics may be damaged. 
Only use battery chargers with a maxi-
mum c

harging voltage of 14.8 V. &
WARNING Risk of e
xplosion due to the
ignition of hydrogen gas
If there is a short circuit or sparks are created,
t
here is a danger of hydrogen gas igniting
when you charge the battery. 
Make sure that the POSITIVE terminal of
a connect

ed battery does not come into
contact with vehicle parts. 
Never place metal objects or tools on a
batt
ery. 
When connecting and disconnecting the
batt
ery, always observe the sequence of
battery terminals described. 326
Breakdown assistance


During starting assistance, always take
car
e to connect only battery terminals of
identical polarity. 
During starting assistance, observe the
seq
uence described for connecting and
disconnecting the jump leads. 
Do not connect or disconnect the bat-
t

ery terminals with the engine running. &
WARNING Risk of e
xplosion due to explo-
sive mixture of gases
An explosive mixture of gases can escape
fr
om the battery during charging and starting
assistance. 
Fire, naked Oames, smoking and cr
eating
sparks must be avoided. 
Make sure there is adequate ventilation. 
Do not stand over the battery. &
WARNING Risk of e
xplosion from a frozen
battery
A discharged battery may freeze at tempera-
tur
es slightly above or below freezing point.
During starting assistance or battery charging,
battery gas can be released. 
Always allow a battery to thaw before
c
harging it or performing starting assis-
tance. If the indicator/warning lamps in the instrument
clus
ter 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 dramatically shortened. The starting char-
acteristics may be impaired, especially at low
temperatures.
It is recommended that you have a thawed battery
checked at a qualiNed specialist workshop. All vehicles
* NOTE Damag
e caused by numerous or
extended attempts to start the engine Numerous or extended attempts to start the
engine ma

y damage the catalytic converter
due to non-combusted fuel. 
Avoid numerous and extended attempts
t

o start the engine. Observe the following points during starting assis-
t
ance and when charging the battery:
= Only use undamaged jump lead/charging
cables with a suPcient cross-section and
insulated terminal clamps.
= Non-insulated parts of the terminal clamps
must not come into contact with other metal
parts while the jump lead/charging cable is
connected to the battery/jump-start connec-
tion point.
= The jump lead/charging cable must not come
into contact with any parts which may move
when the engine is running. Breakdown assistance

approved for Mercedes-Benz.
= Read the battery charger's operating instruc-
tions before charging the battery.
Observe the additional following points during
starting assistance:
= Starting assistance may only be provided
using vehicles, batteries or other jump start
devices with a nominal voltage of 12 V.
= The vehicles must not touch. Starting assistance and charging the 12 V battery

Only have starting assistance provided by a
q

ualiNed specialist workshop, e.g. a
Mercedes-Benz Service Centre. 
Only have the battery charged at a q

towing it away.
For towing, use a tow rope or tow bar with both
axles on the ground. Do not use tow bar systems.
If you notice that the vehicle has lost coolant, do
not have it towed away. Have the vehicle transpor-
ted instead.

swerve or overturn. 
Before tow-starting or towing away,
c

heck if the vehicle to be tow-started or towed away exceeds the permissible
g

ross mass. If a vehicle must be tow-started or towed away, its
per

missible gross mass must not exceed the per-
missible gross mass of the towing vehicle.

Notes on electrical fuses
&
WARNING Risk of accident and injur
y due
to overloaded lines
If you manipulate or bridge a faulty fuse or if
y
ou replace it with a fuse with a higher amper-
age, the electric line could be overloaded.
This could result in a Nre. 
Always replace faulty fuses with speci-
Ned ne

w fuses containing the correct
amperage. *
NOTE Damag
e due to incorrect fuses Using incorrect fuses can result in damage to
electr
ical components or systems or their
functions being considerably restricted. 
Use only fuses approved for Mercedes-
Benz wit

h the respective speciNed fuse
rating. Blown fuses must be replaced with fuses of the
same r
