Hybrid technology combines a fuel efficient
internal combustion engine with a powerful
electric motor. In HYBRID operating mode, the
hybrid drive system automatically selects the
most efficient drive for every driving situation.
Drive the vehicle in the usual manner.
To save fuel in HYBRID mode, the hybrid drive
system switches off the combustion engine as
often as possible during the journey when power
output requirements are low. When power out-
put requirements are low, the electric motor
powers the vehicle. The combustion engine is
automatically activated when power output
requirements are high. The engine is usually
switched off when the vehicle is stationary. Con-
sequently, there is usually no engine idling as
with combustion engine vehicles.
The high-voltage battery stores the energy nee-
ded to operate the electric motor and releases it
again. For pulling away and accelerating, the
electric motor supports the internal combustion
engine using the power stored in the high-volt-
age battery. In addition, the power is used for
partially electric driving, operation of the elec-
tric coolant compressor and to support the 12 V
on-board electrical system. In this way the
hybrid drive system helps to reduce your vehi-
cle's fuel consumption.
At very low outside temperatures the maximum
power output of the high-voltage battery may be
reduced. The high-voltage battery is then not
able to provide the normal electrical power out-
put. At very high outside temperatures, the max-
imum power output of the high-voltage battery
is reduced automatically in order to prevent
damage to the high-voltage battery.

Recuperative Brake System
If you release the accelerator pedal when the
vehicle is in motion, 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 electric energy and stores it in
the high-voltage battery.
The amount of electrical energy generated can
be displayed in the multimedia system display
( page 50).

Acoustic Vehicle Indication (acoustic
presence indicator)
Vehicles with an electric motor generate much
less driving noise than vehicles with internal
combustion engines. As a result, your vehicle
may not be heard by other road users in certain
situations.
Depending on the vehicle's equipment and
country-specific regulations, the vehicle can be
equipped with Acoustic Vehicle Indication which
is an acoustic presence indicator.
Acoustic Vehicle Indication generates a certain
sound at a speed between 0 and 19 mph
(30 km/h). This helps other road users, partic-
ularly pedestrians and cyclists, to hear your
vehicle better. The sound can also be heard
inside the vehicle.
The volume depends on the engine speed. The
faster you accelerate, the louder the sound is. At
a speed of over 19 mph (30 km/h) the sound is
switched off. Above this speed, normal vehicle
noise emission is sufficient for the vehicle to be
heard in good time by other road users.
