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 electric drive. The electric drive 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 9) and the notes on the 12-volt
battery in the Operator’s Manual.26Practical hints221_ZA; 1; 21, en-USd2ureepe,Version: 2.11.8.12009-05-13T13:56:31+02:00 - Seite 26

XConnect the positive terminal clamp of the
charge unit with jump start terminal 1.
XConnect the negative terminal clamp of the
charge unit with jump start terminal 2.
XCharge the 12-volt battery.
Charging the high-voltage battery
With the ignition switched on, the discharged
high-voltage battery is being charged via the
voltage transformer, provided the 12-volt
battery is charged sufficiently. During the
charging procedure the charge unit must
remain connected to the jump start
terminals.
iThe high-voltage battery can only be
charged via the 12-volt battery of your
vehicle. Observe the safety notes
(Y page 9).
XSwitch on the ignition.
The lamps in instrument cluster are on. The
message Charging Hybrid Battery
Please Wait appears in the multifunction
display.
Start the combustion engine when the
message Engine Can Now Be Started
appears in the multifunction display after a
few minutes.
Disconnecting the charge unitXDisconnect the charge unit. Follow the
instructions in the separate operating
instructions of the charge unit.
XInstall the jump start terminal cover
(Y page 28).
XInstall the high-voltage battery cover
(Y page 27).
XClose the hood.XDrive the vehicle for some time in order to
charge the 12-volt battery and the high-
voltage battery.
Jump starting
When the 12-volt battery is discharged, the
combustion engine can be started with
jumper cables and the battery of another
vehicle.
Observe the following:
RJump starting should only be performed
when the combustion engine and the
catalytic converter are cold.
RDo not jump start if the battery is frozen.
Let the battery thaw out first.
ROnly 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.
ROnly use jumper cables with sufficient
cross-section and insulated terminal
clamps.
RAlways make sure the jumper cables are
not on or near pulleys, fans or other parts
that move when an engine is started or
running.
RShould the battery be drained completely,
let the donating power source charge the
vehicle for several minutes before
reattempting the starting process.

iJumper 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.
Make sure the cable clamps do not touch
any other metal part while the other end is
still attached to a battery.
Connecting the jumper cables
XMake sure the two vehicles do not touch.XRemove the high-voltage battery cover
(Y page 27).
XRemove the jump start terminal cover
(Y page 28).
Your vehicle is equipped with two jump start
terminals in the engine compartment.
XConnect jump start terminal = with
positive terminal ; of the external battery
with a jumper cable. Clamp the jumper
cable to jump start terminal 3 first.
XConnect negative terminal 1 of the
external battery with jump start terminal
4 with a jumper cable. Clamp the jumper
cable to negative terminal 1 of the
external battery first.
Starting the combustion engine
XStart the engine of the vehicle with the
charged battery and run it at an engine
speed slightly above idle speed.
XSwitch on the ignition of your vehicle.
The lamps in the instrument cluster come
on. Wait to start the combustion engine, if
the message Charging Hybrid Battery
Please Wait appears in the multifunction
display.
Start the combustion engine only after the
message Engine Can Now Be Started
has appeared in the multifunction display.
This may take a few minutes.
If no messages appear in the
multifunctional display, you can start the
combustion engine directly.
XAfter the combustion engine of your vehicle
has been started, leave the engines of both
vehicles running at idle speed.
