Safety notes
G
Warning!
When your vehicle is in electric drive mode the
engine produces significantly lower noise
levels. Other motorists or pedestriants,
especially those who are visually or hearing
impaired, may be unable to hear your vehicle
while it is in motion. This is particularly true
when driving at lower speeds and during
parking maneuvers. At all times, it is the
responsibility of the driver to be aware of their
surroundings, especially in these low speed
situtations. Otherwise other road users could
be seriously or fatally injured. G
Warning!
Make sure absolutely no objects are
obstructing the pedals’ range of movement. Keep the driver’s footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure the pedals
still have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between or
under the pedals. You could then no longer
brake or accelerate. This could lead to
accidents and injury.
Starting the engine
:
READY indicator
X Switch on the ignition.
X Apply the brake pedal fully and release it.
The self-test of the RBS is completed. For
more information on the RBS, see
(Y page 9).
X Observe the notes on “Starting the engine”
in the Operator’s Manual and start the
combustion engine.
Silent-Start mode
The combustion engine may not start each
time you start the vehicle with the SmartKey
or with KEYLESS-GO.
Depending on various conditions such as the
charging level of the high-voltage battery, you
may drive off with electrical energy alone. The
vehicle is then in Silent-Start mode. The
READY indicator : will then indicate that the
HYBRID systems are operational. 16

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.
Address these messages accordingly and
follow the additional instructions given in this
Supplemental Operating Instructions
Booklet.
Selecting the Vehicle status message
memory menu in the control system displays
both cleared and uncleared messages.
High-priority messages appear in the
multifunction display in red color.
Certain messages of high priority cannot be
cleared from the multifunction display using
the reset button or button &, *,
U or V on the multifunction steering
wheel.
Other messages of high priority and
messages of less immediate priority can be
cleared from the multifunction display using
the reset button or button &, *,
U or V on the multifunction steering
wheel. They are then stored in the Vehicle
status message memory menu. Remember
that clearing a message will only make the
message disappear. Clearing a message will
not correct the condition that caused the
message to appear. G
Warning!
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. G
Warning!
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
R warning/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.
