start. The starter motor
can be heard. R
The engine electronics are malfunctioning.
R The fuel supply is malfunctioning.
X Turn the key back to position gin the ignition lock before attempt-
ing to start the engine again.
X Restart the engine (Y page 96). Avoid excessively long and frequent
attemptstos tart the engine, as this (Y page 96) will drain the bat-

.The starter motor
can be heard. The yellow reserve fuel warning
lamp is lit and the needle
of the fuel gauge shows
0. The fuel tank is empty.
X Refuel the vehicle.
X Bleed the fuel system (Y page 110).The engine does not
start
.You cannot hear
the starter motor. The on-board voltage is too low because the battery is too weak or
discharged.
X Jump-start the vehicle (Y page 227).
If the engine does not start despite attempt stojump-start it:
X Consult aqualified specialist workshop. The starter motor was exposed to excessively high thermal load.
X Allow the starter motor to cool down for approximately two minutes.
X Try to start the engine again.
If the engine still does not start:
X Consult aqualified specialist workshop. The coolant temperature
display is showing more
than 120 †. Adisplay
message may also
appear in the multifunc-
tion display and awarn-

being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant to
cool down.
X Check the coolant level (Y page 215). Observe the warning notes
as you do so and top up the coolant if necessary. If the coolan
tlevel is correct, the radiator fan may be faulty. The cool-
ant is too hot and the engine is not being cooled sufficiently.
X If the coolant temperature is below1 20 †, you can continue driving
to the nearest qualifieds pecialist workshop.
X Avoid heavy loadsont he engine as you do so, e.g. driving in moun-

abattery. There is arisk 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 bat-
tery is electrostatically charged. Electrostatic
charge is created, for example:
R by wearing synthetic-fibre clothing
R by friction between clothing and the seat
R if you pull or push the battery across carpet or
other synthetic materials
R if you rub the battery with acloth G
WARNING
During the charging process, abattery produ-
ces hydrogen gas. If ashort circui toccurs or
sparks are created ,the hydrogen gas can
ignite. There is arisk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicl eparts.
R Never place metal objects or tools on abat-
tery.
R It is important that you observe the descri-
bed order of the battery terminal swhen
connecting and disconnecting abattery.
R When jump-starting, make sure that the
battery pole swith identical polarity are
connected.
R It is particularl yimportant to observe the
described order when connecting and dis-
connecting the jump leads.
R Never connect or disconnect the battery
terminal swhile the engine is running. G

Avoid contact with the skin, eyes and clothing. Wea
reye protection. Keep children at
asafe distance. Observe this Owner's Manual.
For safety reasons, Mercedes-Benz recom-
mends that you use only batteries that have
been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide
increased impact protection to prevent the vehi-
cle occupants from suffering acid burns should
the battery be damaged in the event of an acci- dent.
In order for the battery to achieve the maximumpossible service life, it should always be suffi-
ciently charged.
Like other batteries, the vehicle battery may
discharge over time if you do not use the vehicle.
In such cases, have the battery disconnected at aq uali fied specialist workshop .However, you
can also charge the battery with acharger rec-
ommended by Mercedes-Benz. For more infor-
mation, please contact aquali fied specialist
workshop.
Have the battery charge checked more fre-
quently if yo uuse the vehicle mainly for short
trips or if yo uleave it standing idl efor an exten-
ded period .Consul taq ualified specialist work-
shop if yo uwishtol eave your vehicle parked up
for along period of time.
Whe nyou park the vehicle, remove the key if you
do not require any electrica lconsumers. The
vehicle will then use very little energy, thus con- serving battery power.
i If the power supply has bee
ninterrupted,
e.g. du etoad ischarged battery, yo uwillh ave
