hybrid system combines a combustion engine
with an electric mo tor.
Characteristics when theve hicle is at a standstill:
R The combustion engine is generally switched
o..
R Idle speed only occurs in cer tain instances.
Characteristics when starting theve hicle:
R Ifth e high-voltage battery is su1ciently
ch arge d, theve hicle can be star ted with the
electric drive without the combustion engine
(noiseless start).
R Ifth e high-voltage battery forth e electrical

%
Depending on the system, it may happen that
ev en though the high-voltage battery is
ch arge d, electric mode has restric ted or no
av ailabilit y.Once the combustion engine has
been operated for long enough, electric mode
is again available without restriction.
Charac teristics wi thmoderate po wer output
re qu ests:
R The combustion engine is switched o. as
oTen as possible during the journe y.
R The vehicle can, depending on the drive pro-
gr am selected and the battery charge leve l, be
accelerated electrically up tospeeds of about
140 km/h.
Characteristics with high po wer output requ ests:
R The electric mo tor supports the combustion
engine (boost e.ect), e.g. when pulling away
or accelerating.
R The high-voltage battery is discharging.
Characteristics when releasing the accelerator
pedal during the journe y:
R The electric mo tor is operated as a alternator
when in overrun mode and during braking. R
The high-voltage battery is charging.
No tes on elect ric mode:
R Vehicles with hybrid systems generate signi/-
cant lyless noise when stationary and when
being driven than vehicles with combustion
engines.
R When driving in elect ric mode, theve hicle may
not be heard by otherroad users due tothe
signi/cant lyreduced noise generated.
It is forth is reason that theve hicle is equip-
ped with a sound generator, which ser ves as
an acoustic vehicle warning system (A VAS).
R If not all of theve hicle conditions for electric
mode are met, then the combustion engine is
switched on.
