R
you switch on the turn signals. In this
event, the warnings are suppressed for a
certain period of time.
R a driving safety system intervenes, e.g.
ABS, BAS or ESP ®
.
R you accelerate hard, e.g. kickdown.
R you brake hard.
R you steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly.
R you cut the corner on a sharp bend.
In order that you are warned only when nec-
essary and in good time if you cross the lane marking, the system recognizes certain con-
ditions and warns you accordingly.
The warning vibration occurs earlier if:
R you approach the outer lane marking on a
bend.
R the road has very wide lanes, e.g. a high-
way.
R the system recognizes solid lane markings.
The warning vibration occurs later if:
R the road has narrow lanes.
R you cut the corner on a bend. PLUG-IN HYBRID operation
Points to remember
General notes Hybrid technology combines a fuel efficient
internal combustion engine with a powerful
electric motor. In HYBRIDmode, the hybrid
system automatically selects the most effi-
cient operating mode for every driving situa-
tion. Drive the vehicle in the usual manner.
To save fuel, in HYBRIDmode, the hybrid
system switches off the combustion engine
as often as possible during the journey when power output requirements are low. When
power output requirements are low, the elec-
tric motor powers the vehicle. 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. Consequently,
there is usually no engine idling as with com-
bustion engine vehicles.
For pulling away and accelerating, the electric motor supports the internal combustion
engine using the power stored in the high-
voltage battery. This energy is also used for
driving in partially electric mode, to operate
the electric refrigerant compressor and sup-
port the 12 V on-board electrical system. In
this way the hybrid drive helps to reduce your
vehicle's fuel consumption.
Observe the driving tips on PLUG-IN HYBRID
operation (Y page 287).
Recuperative Brake System If you release the accelerator pedal when the
vehicle is in motion, overrun recuperation is
initiated. The electric motor is operated as a
generator when in overrun mode and when
you brake. Hybrid technology converts the
kinetic energy of the vehicle into electricity
and stores it in the high-voltage battery.
Observe the important safety notes for the
Recuperative Brake System (Y page 48). Important safety notes
If the engine is switched off by the ECO start/
stop function and you open the driver's door:
R a message appears in the multifunction dis-
play and
R a warning tone sounds
Further information (Y page 340).
All of the vehicle's systems remain active, if:
R the vehicle is stationary
R the combustion engine is switched off and
R the READY indicator in the instrument clus-
ter lights up
If you remove your foot from the brake pedal
while in transmission position D or R, the
vehicle may pull away automatically.
Observe the notes on the READY display of
the ECO start/stop function (Y page 288).276
