Various warning labels are attached to your
vehicle. These warning labels are intended to
make you and others aware of various risks.
Do not remove any of these warning labels
unless explicitly instructed to do so by
information on the label itself. Removing
warning labels may cause you and others to
be unaware of certain risks which may result
in an accident and/or personal injury.
Danger of electric shock
The components of the HYBRID system are
indicated by yellow warning labels to make
you aware of high voltage. High-voltage
cables are orange-colored.
GWarning!
The HYBRID system is energized by high
voltage.
You could be seriously or even fatally injured
when you
Rtamper with components or high-voltage
cables of the HYBRID system
Rtouch components or high-voltage cables
of the HYBRID system after the vehicle has
been involved in an accident
Rtouch damaged components of the HYBRID
system
Do not remove covers of components of the
HYBRID system that carry the yellow warning
label. Do not tamper with any components or
with the orange high-voltage cables of the
HYBRID system.

ECO Start/Stop function
When the green READY indicator lamp : in
the instrument cluster is on, the combustion
engine turns off automatically when
R you stop the vehicle and keep the brake
pedal depressed
R you activate the HOLD function
All vehicle systems remain active, for
example the climate control system.
When you remove the foot from the brake
pedal or accelerate when the HOLD function
is activated, the combustion engine starts
automatically. You can drive off as usual.GWarning!
When the green READY indicator lamp in the
instrument cluster is on while the combustion
engine is off, the combustion engine has been
turned off automatically. All vehicle systems
continue to be active. When you open the
driver’s door, unbuckle the seat belt, or take
your foot off of the brake pedal, the
combustion engine starts automatically. The
vehicle could start to drive off. An accident
causing serious or even fatal personal injury
to you and/or others could be the result.
Therefore, always do the following before
leaving the vehicle:
R Engage the electronic parking brake.
R Shift the automatic transmission into park
position P.
R Switch off the ignition. The green or yellow
READY indicator lamp goes out.
The conditions for turning off the combustion
engine automatically are fulfilled when
R the combustion engine has reached its
operating temperature
R the driver seat belt is fastened and the
driver’s door is closed
R the vehicle has exceeded a speed of 9 mph
(15 km/h) after driving off. In subsequent
stop-and-go traffic, brief forward
movement of the vehicle is sufficient
R you take your foot off the accelerator pedal
R the hood is closed and properly engaged
R the automatic transmission is in drive
position D or neutral position N
R the high-voltage battery is charged
sufficiently
R the HYBRID system is operating
undisturbed
i For information on driving with the
DISTRONIC Plus, see ( Y page 18).
When the conditions for turning off the engine
automatically are not fulfilled, the yellow
READY indicator lamp : is illuminated. The
combustion engine does not turn off
automatically when
R the self-diagnosis of the engine
management is still running
R the temperature of the coolant or the
catalyst is too low
R the climate control system of the vehicle
requires the engine to run
R the battery is being charged
R the vehicle has moved backward shortly
before
R the automatic transmission is in reverse
gear R
R automatic emission tests are in progress
After the combustion engine has been turned
off automatically, it restarts automatically in
circumstances, when
R the charging condition of the high-voltage
battery has reached the lower limit
R the settings of the climate control systems
require the engine to run, for example at an
outside temperature over 100‡ (38 †)

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.
