WARNING
If children are left unsupervised in the vehicle, they can:
R open doors and endanger other persons or
road users
R climb out and be injured by the traffic
R operate vehicle equipment and, for exam-
ple, trap themselves. Children could also set the vehicle in motion,
for example by:
R releasing the parking brake
R shifting the automatic transmission out of
park position P
R starting the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle. Always
keep the key out of reach of children.

There is a malfunction in the engine electronics.
R There is a malfunction in the fuel supply.
Before attempting to start the engine again:
X Turn the key back to position 0in the ignition lock.
or X Press the Start/Stop button repeatedly until all indicator lamps in
the instrument cluster go out.
X Try to start the engine again (Y page 160). Avoid excessively long
and frequent attempts to start the engine, as this will drain the
battery.
If the engine does not start after several attempts:
X Consult a qualified specialist workshop. The engine does not
start. The starter motor
can be heard. The
reserve fuel warning
lamp is lit and the fuel
gauge display shows
0. The fuel tank is empty.
X Refuel the vehicle. 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 397).
If the engine does not start despite attempts to jump-start it:
X Consult a qualified specialist workshop. The starter motor was exposed to a thermal load that was too high.
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 a qualified specialist workshop. Vehicles with a petrol
engine:
The engine is not running
smoothly and is misfir-
ing. There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
X Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it.
X Have the cause rectified immediately at a qualified specialist work-
shop. Driving

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 when you pull or push the battery across car-
pet or other synthetic materials
R when you rub the battery with a cloth G
WARNING
During the charging process, a battery produ- ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into con- tact with vehicle parts.
R Never place metal objects or tools on a bat-
tery.
R It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected.
R It is particularly important to observe the
described order when connecting and dis-
connecting the jump leads.
R Never connect or disconnect the battery
terminals while the engine is running. G
WARNING
Battery acid is caustic. There is a risk of injury. Avoid contact with the skin, eyes or clothing.
Do not breathe in any battery gases. Do not
lean over the battery. Keep the batteries out
of the reach of children. Immediately rinse off
battery acid thoroughly with plenty of clean
water and seek medical attention at once. H
Environmental note Batteries contain pollutants.
It is illegal to dispose of them
with the household rubbish.
They must be collected sep-
arately and disposed of in anenvironmentally responsible
recycling system. Dispose of batteries in an
environmentally responsible
manner. Take discharged
batteries to a qualified spe-
cialist workshop or to a col-
lection point for used batter-
ies.
! Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the Service
Booklet or contact a qualified specialist work- shop for more information.
! Always have work on the batteries carried
out at a qualified specialist workshop. Should
it, in exceptional circumstances, be abso-
lutely necessary to disconnect the 12-volt
battery yourself, please observe the follow-
ing:
R secure the vehicle to prevent it from rolling
away.
R switch the ignition off.
R first, disconnect the negative terminal, fol-
lowed by the positive terminal.
The transmission is locked in position Pafter
disconnecting the battery.
After the work has been completed, firmly
reinstall the battery and the cover of the pos- itive terminal.
Comply with safety precautions and take pro-
tective measures when handling batteries. Risk of explosion
Fire, naked flames and smoking are
prohibited when handling the bat-
tery. Avoid creating sparks. Battery (vehicle)

WARNING
If the housing of the high-voltage battery has
been damaged, electrolyte and gases may
leak out. These are poisonous and caustic.
There is a risk of injury.
Avoid contact with the skin, eyes or clothing. Immediately rinse electrolyte splashes off
with water and seek medical attention
straight away.
! Exhaustive discharge caused by the vehicle
standing idle for lengthy periods can damage
the high-voltage battery. If the vehicle is idle
for lengthy periods leave the high-voltage bat- tery connected to a charging station.
Consult a Mercedes-Benz Service Centre if you
wish to leave your vehicle parked up for a long
period of time. Charging the 12 V battery
G
WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a risk of an explosion.
Particularly avoid fire, naked flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery. G
WARNING
Battery acid is caustic. There is a risk of injury. Avoid contact with the skin, eyes or clothing.
Do not breathe in any battery gases. Do not
lean over the battery. Keep the batteries out
of the reach of children. Immediately rinse off
battery acid thoroughly with plenty of clean
water and seek medical attention at once. G
WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases can escape from the battery. There is a risk of
an explosion. Allow the frozen battery to thaw out before
charging it or jump-starting.
! Only use battery chargers with a maximum
charging voltage of 14.8 V.
! Only
charge the battery using the jump-start
connection point.
The jump-starting connection point is in the
engine compartment (Y page 397).
X Open the bonnet.
X Connect the battery charger in the same
order as when connecting the donor battery
during jump-starting: to the positive terminal
and earth point (Y page 397).
Keep away from fire and open flames. Do not
lean over the battery. Never charge the battery
if it is still fitted to the vehicle, unless you use a
battery charger which has been tested and
approved by Mercedes-Benz. A battery charger
unit specially adapted for Mercedes-Benz vehi-
cles and tested and approved by Mercedes-
Benz is available as an accessory. This device
permits charging of the battery in position. Con- tact a Mercedes-Benz Service Centre for infor-
mation and availability. Read the battery charg-
er's operating instructions before charging the
battery.
If the indicator/warning lamps do not light up at
low temperatures, it is very likely that the dis-
charged battery has frozen. In this case you may
neither jump-start the vehicle nor charge the
battery. The service life of a battery that has
been thawed may be reduced. The starting char-
acteristics may be impaired, especially at low
temperatures. Have the thawed battery
checked at a qualified specialist workshop.
PLUG-IN HYBRID vehicles: if the battery
charge is sufficient, the high-voltage battery can also supply the 12 V battery. This only happens
if the battery charge of the 12 V battery requires this, e.g. after using electrical consumers for anextended period with the engine switched off.
As the on-board voltage is continuously moni-
tored this can also be performed when the
engine is switched off. The battery charge of the
12 V battery and the on-board voltage are
thereby kept stable for longer. Battery (vehicle)
