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:
you approach the outer lane marking on a
R
bend.
the road has very wide lanes, e.g. a high-
R
way.
the system recognizes solid lane markings.

The warning vibration occurs later if:
the road has narrow lanes.

Points to remember
General notes
Hybrid technology combines a fuel efficient
internal combustion engine with a powerful
electric motor. In HYBRID mode, 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 HYBRID mode, 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 ( 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.

If the engine is switched off by the ECO start/
stop function and you open the driver's door:
a message appears in the multifunction dis-
