WARNING Risk ofexplosion from hydro‐
ge nga s igniting
A battery generates hydrogen gas during the
ch arging process. If there is a short circuit or
spar ksstart toform ,th ere is a danger of the
hy drogen gas igniting. #
Make sure that the positive term inal of
th e connected battery does not come
into contact with vehicle parts. #
Never place me tal objects or tools on a
batter y. #
When connecting and disconnecting the
batter y,yo u must obse rveth e described
order forth e battery clamps. #
When giving starting assistance, alw ays
make sure that you on lyconnect battery
te rm inals with identical polarity. #
During starting assis tance, you must
obse rveth e described order for con‐
necting and disconnecting the jumper
cables. #
Do not connect or disconnect the bat‐
te ry cla mp s while the engine is running. &
WARNING Risk ofexplosion during
ch arging process and starting assis tance
During thech arging process and starting
assis tance, the battery may release an explo‐
sive gas mixture. #
Avoid fire , open flames, creating spar ks
and smoking. #
Make sure that there is suf ficient venti‐
lation du ring thech arging process and
during starting assis tance. #
Do not lean over a batter y. &
WARNING Risk ofexplosion from a fro‐
zen battery
A dischar ged battery may freeze at temp era‐
tures slightly abo veor below freezing point.
During starting assis tance or battery charg‐
ing, battery gas may be released. #
Alwaysth aw a frozen battery out first
before charging it or per form ing starting
assis tance. If
th ewa rning/indicator lamps do not light up in
th e instrument display around or below freezing point, it is
very likely that the discharged battery
has frozen.
In this case, obser vethefo llowing points:
R do not give theve hicle starting assis tance or
ch arge the battery
R the service life of a battery that has been
th awe d may be reduced drastically
R thest art-up behavior may de teriorate, partic‐
ularly at low temp eratures
R it is recommended that you ha veath awed
battery checked at a qualified specialist work‐
shop

TEDama gecaused bynume rous or
ex tended attempts tostart the engine Nume
rous or extended attempts tostart the
engine may damage the catalytic con verter
due tonon-combu sted fuel. #
Avoid numerous and extended attem pts
to start the engine. Obser
vethefo llowing points during starting
assis tance and when charging the battery:
R only use undamaged jumper cables/charging
cables with a suf ficient cross-section and
insula tedte rm inal clamps
R non-insulated parts of thete rm inal clamps
must not come into con tact wi thother me tal
parts while the jumper cables/charging
cables are connected tothe battery/jump-
st art connection point
R the jumper cables/charging cable must not
come into contact with any parts which may
mo vewhen the engine is running
R alwa ys make sure that nei ther you nor the
battery is electros tatically charged
R alwayske ep away from fire and open flames
R do not lean over a battery
R when charging: only use a battery charger
th at has been tested and appr ovedby
Mercedes-Benz and read the operating
instructions foryo ur charge r before charging
th e batter y.
Obser vethe additional following points during
st arting assis tance:
R starting assis tance may only be pr ovided
using batteries with a nominal voltage of 12 V
R theve hicles must not touch each other 220

Vehicles with a battery main switch: check
whe ther the battery main switch is switched
on (/ page114). #
Secu retheve hicle using the parking brake. #
Vehicles with automatic transmission:
shift the transmission toposition 005D. #
Switch off the ignition and all electrical con‐
sumers. #
Open the hood (/ page 202). Example: jump-s

Remo vethe co ver from the positive term inal
on the donor batter y. #
First, connect the positive term inal clamp of
th e jumper cables/charging cables tothe
positive term inal of theot her vehicle's bat‐
te ry. #
With positive term inal clamp 2ofthe
jumper cable, slide there d pr otective cap on
jump-s tart connection point 1back with a
clockwise turn. #
Connect the positive term inal clamp tothe
positive term inal of jump-s tart connection
point 1. #
During starting assistance: start the engine
of the donor vehicle and let it run at idle
speed. #
Connect the negative term inal of the donor
battery tothe ground point of your ow nve hi‐ cle with
the jumper cable/charging cable.
Begin with the donor batter y. #
During starting assistance: start the engine
on your ow nve hicle. #
When charging: start thech arging process. #
During starting assistance: letthe engine
ru nfo r a few minutes. #
During starting assistance: before discon‐
necting the jumper cable, switch on an elec‐
trical consumer on your ow nve hicle, e.g. the
re ar wind owheater or lighting.
When thest arting assis tance/charging process is
comple te: #
First,re mo vethe jumper cables/charging
cables from the ground point and negative
te rm inal of theot her vehicle's batter y,then
from the positive term inal of jump-s tart con‐
nection point 1and the positive term inal of
th eot her vehicle's batter y.Each time, begin
at the contacts on your ow nve hicle.
The red pr otective cap springs back toits ini‐
tial position when positive term inal clamp 2
is disconnected from jump-s tart connection
