Risk of inju
ry
Fo rs afety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. Thes ebatteries provide
increased impact protection to prevent vehi-
cle occupant sfrom suffering aci dburns
should the battery be damaged in the event
of an accident.
To prevent acid burns, observe the following
safety notes when handling batteries:
R do not lean over the battery.
R do not place any metal objects on abattery.
Otherwise ,you coul dcause ashort circuit
and the battery's gas mixtur ecould ignite.
R mak esure that you do not create an elec-
trostatic charge, e.g. by wearing synthetic
clothing or as aresult of friction on fabrics.
Therefore, you should not pull or slide the
batter yover carpets or other synthetic
materials.
R neve rtouch the battery first. To discharge
ap ossible electrostatic charge, step out of
the vehicle first and touc hthe bodywork.
R do not wipe the battery usin gacloth. The
battery may explode as aresult of electro-
static charge or due to flying sparks.
! Switc hoff th eengine and remove the key
before disconnectin gthe termi nalclamps
from the battery .Onvehicles with KEY-
LE SS -GO, make sure that the ignition is
switched off. Check that all the indicator
lamps in the instrument cluste rare off.
Otherwise, yo umay destroy electronic
components, such as the alternator.
i Remove the key if you park the vehicle
and do not require any electrical consum-
ers. The vehicle will then use very little
energy, thus conserving battery power.
Mercedes-Benz recommends that you do not
carr yout work on batteries yourself, e.g.
removing, charging or replacing. Always have this work performed at
aqualified specialist
workshop, e.g. aMercedes-Ben zService
Cent re. Installation location of the battery

the ignition lock and remove it, or, with
KEYLESS-GO, make sure that the ignition

Ris
kofi njury
Only charge the batter yinawell-ventilated
area. As the battery is being charged ,gases
can escape and generate minor explosions.
This could injure you and other persons or
cause damage to the paintwork or acid cor-
rosion on the vehicle.
You can obtain information about battery
chargers which allow the battery to be
charged while still installed from aqualified
specialist workshop ,e.g. aM ercedes-Benz
Ser vice Centre. G
Risk of injury
There is arisk of acid burns during the charg-
ing process due to the gases which escape
from the battery. Do not lean over the battery

approved by Mercedes -Benz .These battery
chargers allow the battery to be charged
while still installed.
! Only use battery chargers with amaxi-
mum charging voltage of 14.8 V.

Risk of injury
There is arisk of acid burns when jump-starting avehicle due to the gases which escape from
the battery. Do not lean over the batter ywhile the engin eisbeing jump-started. G
Risk of explosion
Gases escapin gfrom th ebattery during jump-starting may cause minor explosions. Avoid cre-
ating sparks. Keep naked flames away from the battery, and do not smoke.
Comply with safety precautions when handling batteries. You will find these under "Battery" in
the index.
! Avoid repeated and lengthy startin gattempts. Otherwise, non-combuste dfuel may dam-
age the catalytic converter 41
and create arisk of fire.
Do not use arapid-charging device to start the engine.
Make sure the jump leads are not damaged.
Make sure the jump leads are not touching any other metal objects when they are connected
to the battery.
If your vehicle's battery is discharged ,the engin ecan be jump-started from another vehicle
or from asecond batter yusing jum pleads.
Observ ethe followin gpoints:
X The battery is not accessible in all vehicles. If the other vehicle' sbattery is not accessible,
jump-start the vehicle using asecond batter yorajump-star ting device.
X Only jump-start the vehicl ewhen th eengineisc old an dthe catalytic converter system has
cooled down 42
.
X Do no tstart the engine if the battery is frozen. Let the battery thaw first.
X Jump-starting may only be performed from batterie swithanominal voltage of 12 V.
X Only use jum pleads which have asufficient cross-section and insulated terminal clamps.
X Make sure that the jump leads cannot come into contact with parts, such as the pulley or
the fan. Thes eparts move when the engine is started and while it is running.
X If the battery is fully discharged ,leave the batter ythat is being used to jump-star tconnected
for afew minutes befor eattempting to start. This charges the battery alittle.
i Jump leads and further information about jump-startin gcan be obtained from any
Mercedes-Ben zService Centre.
X Make sure that the two vehicles do not touch.
X Apply the parking brak efirmly.
X Manual transmission: engage neutral.
X Automatic transmission: move the selector lever toP.

missible gross vehicle weigh tofyour vehicle. G
Risk of accident
The vehicle is braked when the HOL Dfunction
or DISTRONIC PLUS is activated. Therefore,
deactivate HOLD and DISTRONIC PLUS if the
vehicle is to be towed.
It is better to have the vehicle transported
than to have it towed.
! Whe ntowing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles coul dbedamaged.
! Do not use the towing eye for recovery,
as this could damage the vehicle. If in
doubt, recover the vehicle with acrane.
! Youm ay tow the vehicle for amaximum
of 50 km. Atowing speed of 50 km /h must
no tbee xceeded.
For towing distances over 50 km, the entire
vehicl emust be lifted up and transported.
! On vehicles with KEYLESS-GO, use the
key instead of the Start/Stop button .Turn
the key to position 2in the ignition lock and
shif tthe automatic transmission to N.
Then, turn the key back to 0and leave it in
the ignitio nlock.
! Only secur ethe tow cable or towing bar
to the towing eyes. You could otherwise
damage the vehicle.
Please note:
R vehicles with an automatic transmission
must not be tow-started.
R if you ar etowing the vehicle over alonger
distance, this must be done with the rear
axle raised.
R the ignition must be switched off if you are
towin gthe vehicle with the rea raxle raised. Intervention by ESP
®
could otherwis edam-
age the brake system.
R if the vehicle has suffered transmission
damage, only tow it with the propelle rshaft
disconnected.
R if the engin edoes not start, tr yjump-start-
ing it (Y page 289).
R if it is not possible to jump-start the vehicle,
have it towed to the nearest qualified spe-
cialist workshop, e.g. aMercedes-Benz
Servic eCentre.
R the automatic transmission must be in
position Nwhen the vehicle is being towed.
Before towing the vehicle, mak esure that the
battery is connected and charged. You will
otherwis ebeunable to switch on the ignition
or shift the transmissio ntoNin vehicles with
an automatic transmission.
i Switch off the automatic locking feature
before the vehicle is towed (Y page 208).
You could otherwise be locked out when
pushing or towing the vehicle. Fitting the towing eye
Vehicles with atrailer to whitch: if you intend
to use the vehicle for towing, fold out the ball
coupling and connect the towbar to it
(Y page 186).

koff ire
Only use fuses that have been approve dfor
Mercedes-Ben zvehicles and which have the
cor rect fuse rating for the systems con-
cerned. Do not attempt to repai rorbridge
faulty fuses .Otherwise, acircuit overload
could cause afire. Have the cause traced and
rectified at aqualified specialist workshop,
e.g. aMercedes-Benz Ser vice Centre. Blow
nfuses must be replaced with fuses of
the same rating, which you can recognise by
the colour and value. The fuse ratings are lis-
ted in the fuse allocation chart .AMercedes-
Ben zService Cent rewill be happy to advise
you.
If the newly inserted fuse also blows, have the
cause traced and rectified at aqualified spe-
cialist workshop, e.g. aMercedes-Benz
Ser vice Centre.
