Introduction
The HYBRID technology combines an
economical combustion engine with a
powerful electric drive. The HYBRID system
selects the most efficient operating mode for
each driving situation automatically. You can
drive the vehicle in the usual manner.
The HYBRID system turns the combustion
engine off when stopping as often as possible
in order to save fuel. You will just have to
continue to keep the brake pedal depressed
or to activate the HOLD function. Thus, the
engine should normally never run at idle
speed.
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.
G
Warning!
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.
Driving off and accelerating consumes the
most energy. Thus, the electric drive supports
the combustion engine with the energy stored
in the high-voltage battery. The energy is also
used for semi-electrical driving, for operation
of the electric compressor of the cooling
system and to support the 12-volt on-board
power supply. The hybrid drive thereby
contributes significantly to the fuel economy
of your vehicle.
For information on driving and parking, see
(Y page 16).
The current operating mode of the HYBRID
system can be displayed in the multifunction
display and in the COMAND display
(Y page 14).
The COMAND can also display a chart of the
fuel consumption and the electric power that
has been generated (Y page 16).
RBS
With the RBS activated (Y page 10), the
electric drive functions as a generator when
coasting and braking. HYBRID converts the
energy of movement into electric power and
stores it in the high-voltage battery. The high-
voltage battery does not require additional
charging by other means.
