Electric drive readiness, silent start

The vehicle is ready to drive without starting the

can be activated within an interval of approx. 2
to 60 seconds after radio readiness is switched
on, under the following conditions:

conditions met to allow electric driving,
refer to page

During electric driving, please note that
pedestrians and other road users may fail

to notice the vehicle in the usual way due to the
lack of engine noise. For example, proceed with
particular caution when pulling into and out of a
parking space.

Starting the combustion engine

When drive readiness is switched on under the
following circumstances, the combustion
engine is started:

drive system not at operating temperature

high temperature of hybrid system

insufficient charge state of high-voltage
battery or fully charged high-voltage battery

If a Silent start is not possible:
Avoid frequent starting of the combustion

engine in quick succession or repeated starting
attempts in which the engine does not start.
Otherwise, the fuel is not burned or inade-
quately burned and there is a danger of over-
heating and damaging the catalytic converter.
