Points to note
G
WARNING
When the vehicle is stationary and the green
READY indicator in the instrument cluster is
lit, this means that the engine has been
switched off automatically. All of the vehicle's
systems remain active.
If you remove your foot from the brake pedal
while in transmission position D or R, the
vehicle may pull away automatically.
There is a risk of an accident.
Exit the vehicle only if:
R
both the green and yellow READY
indicators in the instrument cluster are off
R
you have secured the vehicle to prevent it
from rolling away.
Hybrid technology combines a fuel efficient
internal combustion engine with a powerful
electric motor. The hybrid system
automatically selects the most efficient
operating mode for every driving situation.
Drive the vehicle in the usual manner.
In order to save fuel, the hybrid system
switches the engine off as often as possible,
whenever less power output is required as
you drive. When the output required is low,
propulsion is provided by the electric motor.
The engine is switched on, even while the
vehicle is in motion, when a higher power
output is required. The engine is usually
switched off when the vehicle is stationary.
The typical idling of conventional engines is
therefore generally absent.
For the high-consumption tasks of pulling
away and accelerating, the electric motor
assists the internal combustion engine using
the stored energy from the high-voltage
battery. This energy is also used for driving in
partially electric mode, to operate the electric
refrigerant compressor and support the 12 V
on-board electrical system. In this manner,
the hybrid drive makes a crucial contribution
to fuel conservation.
Notes on driving and parking (
Y
page 21).
You can display the hybrid system's current
operating mode in the multifunction display
and the COMAND display (
Y
page 30).
In the COMAND display, you can also call up
a graphic display of the fuel consumption and
generated electricity (
Y
page 33).
RBS
If you have activated RBS (
Y
page 15), the
electric motor will operate as a generator in
overrun mode and when braking. Hybrid
technology converts the kinetic energy of the
vehicle into electricity and stores it in the
high-voltage battery. It is unnecessary to
additionally charge the high-voltage battery
via an external power system.
