Notes
Your vehicle is equipped with a 12-volt
battery and a high-voltage battery. The high-
voltage battery stores the power required for
the hybrid transmission. The hybrid
transmission also starts the combustion
engine.
Have any work on the batteries performed at
an authorized Mercedes-Benz Center.
i Read and observe the safety notes
(Y page 8) and the notes on the 12-volt
battery in the Operator’s Manual. G
Warning!
The electrolyte, i.e. the battery fluid, is toxic
and caustic. Do not allow this fluid to come in
contact with eyes, skin or clothing, for
example in case of an accident.
In case it does, immediately flush affected
area with water and seek medical help
immediately.
For information on the location of the 12-volt
battery and the high-voltage battery, see
(Y page 12). !
Deep discharge caused by prolonged
periods of the vehicle not being used, can
damage the high-voltage battery.
During such periods, operate the vehicle
every 4 weeks for several minutes in order
to charge the high-voltage battery.
During the charging process, switch off
electrical consumers that are currently not
needed, e.g. climate control system or seat
heating.
If necessary, get a jump start. G
Warning!
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and lead to death. Do not
run the engine in confined areas (such as a
garage) which are not properly ventilated.
If you do not intend to operate your vehicle
for an extended period of time, contact an
authorized Mercedes-Benz Center about
steps you need to observe. Charging the battery
Charging the 12-volt battery G
Warning!
Never charge a battery while still installed in
the vehicle unless the accessory battery
charge unit approved by Mercedes-Benz is
being used. Gases may escape during
charging and could cause an explosion that
may result in personal injury, paint damage or
corrosion.
An accessory battery charge unit specially
adapted for Mercedes-Benz vehicles and
tested and approved by Mercedes-Benz is
available. It permits the charging of the
battery in its installed position. Contact an
authorized Mercedes-Benz Center for
information and availability. 32

direction of arrow.
X Connect the positive terminal clamp of the
charge unit with positive terminal 2.
X Slide cover = from the negative terminal
in direction of arrow.
X Connect the negative terminal clip of the

X Charge the 12-volt battery.
Disconnecting the charge unit X
After the combustion engine has been
started, disconnect the charge unit. Follow
the instructions in the separate operating
instructions of the charge unit.
X Close the hood.
X Drive the vehicle for some time in order to
charge the 12-volt battery. Jump starting
When the 12-volt battery or the high-voltage
battery is discharged, the combustion engine
can be started with jumper cables and the
battery of another vehicle. Observe the following:
R
Jump starting should only be performed
when the combustion engine and the
catalytic converter are cold.
R Do not jump start if the battery is frozen.
Let the battery thaw out first.
R Only jump start from batteries with the
same voltage rating (12 V). Jump starting
with a more powerful battery could damage
the vehicle’s electrical system, which is not
covered by the Mercedes-Benz Limited
Warranty.
R Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.
R Always make sure the jumper cables are
not on or near pulleys, fans or other parts
that move when an engine is started or
running.
R Should the battery be drained completely,
let the donating power source charge the
vehicle for several minutes before
reattempting the starting process.
i Jumper cables and additional information
on jump starting are available at any
authorized Mercedes-Benz Center.
! Jump starting should only be performed
using the jump-start terminals located in
the engine compartment.
Avoid repeated and lengthy starting
attempts.
Do not attempt to start the engine using a
battery quick-charge unit.
If the engine does not run after several
unsuccessful starting attempts, have it
checked at the nearest authorized
Mercedes-Benz Center.
Excessive unburned fuel generated by
repeated failed starting attempts may
damage the catalytic converter and may
present a fire risk.
Make sure the jumper cables do not have
loose or missing insulation. Practical hints

battery C with negative terminal B with a jumper cable. Clamp the cable to
negative terminal ? of charged battery
C first. Starting the combustion engine
X Start the engine of the vehicle with the
charged battery and run it at an engine
speed slightly above idle speed.
X Make sure the automatic transmission is in
park position P.
X Starting the jump start process with
the SmartKey: To start the charging
process for the high-voltage battery, turn
the SmartKey in the starter switch first into
starting position 3.
X Turn the SmartKey back into ignition
position 2.
X Starting the jump start process with
