Ve hicles with hybrid systems generate signi/-
cant lyless noise when stationary and when being
driven than vehicles with combustion engines.
When driving in elect ric mode, theve hicle may
not be heard by otherroad users due tothe signif-

forth is reason that theve hicle is equipped

Call the /re brigade. The
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
drive is not su1ciently charge d or the operat-
ing temp erature of the combustion engine has
not been reached, theve hicle can start with
th e combustion engine.
% 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.
% Tostart the combustion engine, the high-volt-
