Climate control
Notes
The climate control system is available when
the vehicle is operational and the green or
yellow READY indicator lamp is on.
The set temperature of the vehicle interior is
maintained for a certain period after the
combustion engine was turned off
automatically. Air recirculation switches on
automatically. The indicator lamp in rocker
switch g is not lit when the air
recirculation mode is switched on
automatically.
Air conditioning switched on
automatically
If the operating temperature of the high-
voltage battery is too high, it will be cooled by
the climate control system. The air
conditioning switches on automatically.
In such circumstances it is not possible to
switch off the air conditioning via COMAND
for several minutes.
i For more information on the climate
control system, refer to the Operator’s
Manual.

Vehicle status messages in the
multifunction display
Notes
Warning and malfunction messages appear in
the multifunction display located in the
instrument cluster. Certain warning and
malfunction messages are accompanied by
an audible signal.
High-priority messages are shown in red in
the multifunction display. Messages of lower
priority are also shown in yellow or white.
Address these messages accordingly and
follow the additional instruction given in this
Supplemental Operating Instructions Booklet
and in the Operator’s Manual.
GWarning!
All categories of messages contain important
information which should be taken note of
and, where a malfunction is indicated,
addressed as soon as possible at an
authorized Mercedes-Benz Center.
Failure to repair the condition noted may
cause damage not covered by the Mercedes-
Benz Limited Warranty, or result in property
damage or personal injury.
GWarning!
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see
information about your driving conditions,
such as
R speed
R outside temperature
Rwarning/indicator lamps
R malfunction/warning messages
R failure of any systems
Driving characteristics may be impaired.
If you must continue to drive, do so with added
caution. Contact an authorized Mercedes-
Benz Center as soon as possible.
On the pages that follow, you will find a
compilation of the warning and malfunction
messages specific to the HYBRID system. For
all other warning and malfunction messages,
refer to the Operator’s Manual.
Clearing display messages
Some display messages with low priority are
cleared from the multifunction display after
several seconds. Other display messages
remain displayed in the multifunction display
until you clear them manually.
Certain messages of high priority cannot be
cleared from the multifunction display. Such
messages will appear in the multifunction
display until the causes for these messages
have been repaired.
Use the buttons on the multifunction steering
wheel.
XClear the messages using button a or

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

GWarning!
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 13).
! 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.
GWarning!
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.

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.
